I just want some clarification, if someone could help me.

I keept getting an annoying PM by some "nyisles" on another forum.

He keeps on telling me how the MSP can take boost like there was nothing.

He keeps saying the MSP's stock internals wern't changed because mazda thought they were good enough to handle large amounts of boost.

Same goes with the tranny he thinks the tranny should beable to hold maybe 280 whp with no problems.

He also says the stock piping/intercooler are perfect the way they are, and that they are not restrictive in anyway shape or form.

oh yea, and upgrading the BOV for that "whosh whosh" sound makes no performance increase (which I'm not too sure about) and it's just rice.

oh yea then he was comparing the MSP to a DSM where he said "there are alot of DSMs running deep into 13s on stock internals/piping, so there goes your argument about that" Which means there goes my arguement that the MSP supposedly can't take too much more boost before needing to upgrade some internals/piping.

Oh yea, and he said I Didn't know anything about turbocharged cars (which is semi true...I know a good amount...but not enough to be called any sort of expert)

Oh yea about handling, he didn't seem to understand...I told him a Stock Spec can keep up with an ITR (in stock autocrossing, with professional drivers in both cars), and would probally fall behind an MSP, but not enough to make a HUGE diffrence, but with equal drivers the MSP should beat a spec in handling, but not big enough of a diffrence that you should like write home to your mom about (maybe like in autox a few secs diff (I'm a NEWB to auto x, so I'm not sure if that's alot of time or not)

But anyone else lilke to agree/disagree with him?

Oh yea this thread was not a VS thread of anykind, or anything to bash the MSP.

I'm just trying to get some proof that THERE are restrictions with the MSP's intercooler/piping, and the boost is kept low to protect the engine/tranny.

No one has had a failed tranny yet due to high levels of hp. besides that, the rest sounds false. except the BOV im not sure on that one.
 
The guy is fool of total s***.
Everything you mentioned he said is not true, from the tranny to the internals to the intercooler.

Haaa what tool:rolleyes:
And the bov will not give HP but it will combat compressure surge when the boost is raised and helps keep the turbo spooled when shifting......and by the way BOV's are not rice....far from it.
Altezza's, neon chrome rims and bleacher bench spoilers are

hhaaa what a tool:rolleyes:

yea...but I was talking about long term reliability...280whp sounds alot to me...like as a daily driver...

I'm sure there's more than just power, like if you do alot of clutch dumping it'll be harder on the tranny as well.

But I'm right...and I knew it..thanks for your replies, I sent him the link in a PM, hopefully NOW he'll understand.

OK,not to sound like an a$$,but if i hear one more person on this forum ask whether a BOV adds HP im gonna lose it!(pissed)
If you dont know what you're talking about then ask Q's from guys that do but dont make yourself look stupid!If you know someone is wrong that is trying to tell you otherwise then either educate them or ignore them and let them blow up their own s*it or anyones who is dumb enough to listen!!!!!(stupid)DSM cars will take a lot of power on stock internals(i know from much experience/17+lbs. of boost on a daily basis!)but their trannys are weak (had this discussion once already tonight)IMHO,i dont think many if any(person) on here know exactly what our MSP motors will take for boost ,for power or how the trannys will hold up under more power than they came with for the fact that i dont think any of us have enough miles on a modded car to give reliable info on these things!!! Not that im mad at any one but im tired of guys giving info that is just an opinion.Opinions dont count ,just because someone thinks i can run 15psi out of my turbo doesnt mean im gonna do it......SHOW ME THE FACTS!If you dont have facts then continue to give your opinions but make sure that you show that it is only an opinion!There is a lot of guys out there that dont know a lot about cars and rely on the info they find on this board.I wouldnt want to be the guy who blows his motor listening to people who dont know (facts) but state their opinion and he/she listened to them like they are a car god.

OK,i think ive said enough and i hope the right people get the point.Please let me know what you think of my OPINION!


This is a rant but i hope you will see the meaning.(hmm)
 
haha how can he say that plastic piping isn't restrictive. i think it sucks that our charge/intercooler piping is plastic. puts a big hastle on us tuners.
 
Yeah DSM's r great till they crank walk and fuckzord the motor! Yeah BOV dont give you horse power but can cure the lose of it from leaky ones.
 
Daewoos, if you're going to call someone out on a message board, it's common courtesy to at least try and give both sides of the story. But you couldn't do that, because you know that then the people here will see what a moron you are. Now it's time to level the playing field.

Since Daewoos didn't bother to give any background on the whole thing, here is the thread that the argument originated in:


http://www.b15sentra.net/forums/showthread.php?s=&threadid=51185&perpage=15&pagenumber=7

Please note the third-to-last post on that page. The mods locked the thread before I even saw the post, so I PM'd my response to this guy because I didn't want him to think he had "0WN3D" me with his ignorance or whatever. Since he thought it would be a good idea to twist just about everything I said in his post here, I will just paste the exact PM that I sent him over on b15sentra.net. Obviously, the sections inside the quote tags are parts of his tard-post that I was replying to.

"You must be glad these mods locked that thread. I'd still like to point out some horrendous problems with the post you made, though ;)

no the QR25 can handle power...it just can't handle boost. There is a diffrence.

How do you plan to put down 250+hp without some sort of boost, or nitrous? The QR25 isn't going to hold up to a big hit of nitrous any better or worse than it will handle boost.

A combination of Boost + power makes it worse (for an engine) the TRANNY all you need to talk about is power.

What?! This doesn't even make sense. Are you still trying to say that the SpecV trans will hold up better to high amounts of power than the MSP trans? If so, please show me this phantom information that educated you on just how much power the MSP trans can hold.

I'd also want to upgrade the BOV to make a nicer whoosh sound...and for more power...the wastegate I'd replace with a better one again for more power...and have you SEEN the piping, that's what's restricting EVERYTHING.

"Upgrading" the BOV for a "woosh sound" is rice, pure and simple. Hell, if the MSP's engine is MAF-based, setting up a BOV to make a "woosh sound" (read: vent to atmosphere) will make the car run WORSE, not better. Also, how will a "better" wastegate give you more power? Do you even know what a wastegates and BOVs are for? I'm thinking no.

As far as the piping issue goes, can you tell me the diameter of the stock MSP intake pipes? If not, then your comments make no sense. Just going on "well it LOOKS like it's restrictive" makes you sound foolish. Hell, there are guys with DSMs running deep into the 13s on the dinky stock intake piping, so there goes that argument.

Do your research first before you open your mouth.

LOL, this coming from someone who obviously doesn't know the first thing about turbocharged cars and just tried to lecture me about them. What irony!

Also JWT has a Turbo kit in the works, that supposedly has new internals with it for 5-6K. I know it's far easier to beef up an motor, than it is a tranny.

Not exactly. It all depends on the car and the options available, as well as whether or not the tranny even needs "beefing up." Plenty of cars (imports and domestics alike) can run far greater amounts of power over stock without having to do a damn thing to the trans.

The MSP also DOES not blow the Spec out of the water for handling. It feels a hell of alot more stable...but the Spec CAN I repeat CAN stick with the MSP. Stock for stock, the MSP just bearly outshines a ITR, the Spec can and on occasion beats the ITR in autox stock for stock with professional drivers. And the Spec is probally sitting higher than both cars, seeing the MSP is lowered, and the ITR is low as well compared to you the spec is like a 4X4 (well...you get the point)

Sorry, but it does. The MSP is one of the best-handling FWD cars in recent history. The only time a Spec-V is going to beat a Type-R on the track is if the Type-R driver is inferior, which is the case with just about any car. Put an expert driver in a Civic and a crap driver in a Vette Z06 and the vette will get outhandled... that doesn't mean the Civic handles better. Comparing autocross results, where the drivers vary from total novice to very experienced, is a poor way to determine if one car handles better than another.

But the Spec can also be made to handle well...your point?

What do you mean, "your point?" ANY car can be made to handle well if you throw enough money at it... we are talking stock vs stock here, not modded vs stock. Ricers love to talk about how fox-body Mustangs "can only go straight," but invest a few grand in a Griggs track suspension setup and a 5.0 can handle like a supercar. Mods are beyond the scope of the argument, sorry.

DO YOU KNOW why most turbo charged cars can be MADE to go fast easily? Because they came out of the factory with BEEFED UP internals, beefed up trannys, HUGE intercoolers, and decent sized piping. All THEY need is a Boost controler, and maybe a new wastegate.

Like you would say, "again you open your mouth without doing any research." Tell me now, which factory-turbo cars do you know that came with "huge" intercoolers? The SRT4 is one of the few cars to ever come with a factory front-mount intercooler, and it's far from huge. Most other cars came with a dinky factory side-mount intercooler which ends up being one of the first things people upgrade. And again, please tell me why they would need a "new" wastegate... I'd love to hear your reasoning!

the MSP doesn't come with anything more beefed up than a clutch. it doesn't handle boost well at all. And the intercooler, and piping is so damned restrictive.

How do you know how well it handles boost? Did you ever stop to think that maybe Mazda didn't "beef up" the engine because it handles boost well enough in its existing form? Please, show me how many people with MSPs have already blown their engines since they're so weak. Feel free to show me this phantom restrictive intercooler and piping as well... I'd be surprised if you even know the diameter of the piping, or flow numbers for the intercooler.

the MSP's engine can take more boost than the specs...but the tranny is no where near as durable as the engine. It's estimated it'll blow at 220- 240 whp (which is still alot of whp, but if I continue with my spec it'll be nothing)

Estimated by who? Where are you getting this crap?

Again beefing up an engine is realitivly cheap compared to beefing up a tranny.

Is there an echo in here? Is there an echo in here?

All mazda did was, take a protege, throw on a turbo, and that's their car. It would be the EXACT same thing as if Nissan took the spec v and threw a turbo on it. cept the turbo spec v would be making ALOT more power than the MSP would.

... and the turbo Spec-V would either be running 5psi maximum, or the engines would be blowing up after 10,000 mi. Also, if your aunt had balls then she'd be your uncle. But she probably doesn't, and Nissan isn't going to be making any turbo Spec-V, so let's stay away from the "if" game.

Point to take a note: The only turbo cars done right (for tuning) in north america. is the GTi 1.8, the SRT-4, the Evo8, and the WRX.
Funny how the MSP isn't fitting into this picture.

Point to note: A list of "turbo cars done right" from somebody who clearly doesn't know what they're talking about is not to be considered valid.

Another point to note: The only cars I'd really ever concider majorly building up on is the EVO8 and the WRX. FWD cars hold nothing compared to RWD/AWD cars.

Finally, you say something that makes sense! Bravo. :D "

There you have it, 100% unedited. So from this, somehow this guy reached the following conclusions:

1. I believe that the MS Protege can handle large amounts of boost on stock internals. Uhh no, I never said that. What I did say was that it can handle more than the QR25DE, and that Mazda saw the engine fit enough to handle a decent enough amount of boost to be sold with a turbo without being built up. This is common sense... Mazda wouldn't sell a car without building the engine if it thought the engine was on the edge of failure just by running stock boost, because this would be horribly costly when the engine replacements under warranty started coming in.

2. I think the intercooler and intake piping is "perfect." I never said this, I simply said that unless the intake piping is of extremely small diameter, it's not a bottleneck and doesn't need to be upgraded unless you plan to run serious amounts of boost above stock. If anyone knows the diameter of the stock MSP intake piping, this would come in handy right about now :D Remember, when it comes to intake/intercooler pipes, bigger is NOT always better.

3. I think the MSP engine has a bottom end as durable as the 4G63's. LOL, uhh... no. Again, trying to twist words will get you nowhere...
 
Modifying a recirculating BOV (or diverter valve, or shift valve, etc) or using an aftermarket BOV just to make a "wooshing" sound on an otherwise-stock car IS rice, sorry if you are in denial about this. Just about every factory-turbo car comes with a BOV these days (exactly for the reasons that "spoolinmp3" mentioned), however most of them are rerouted back into the intake tract to avoid confusing the MAF sensor. Venting to atmosphere causes the car to run rich, since the ECU will be providing fuel for air that isn't reaching the cylinders, which can cause rough running and/or stalling. If your car uses a computer with a MAP-based system for measuring the incoming air, then venting to the atmosphere is fine because it measures the air in a way that won't cause extra fuel to get dumped if you're pissing the air out of the intake tract.

You are also grasping at tiny straws in terms of the handling thing... you just need to admit when another car can outhandle yours and be done with it, none of this "well ok but it's still close, and with the right mods or the right driver or blah blah blah blah..." nonsense. Also, "a few secs" at an autocross is a significant difference.

I think that about covers everything. Sorry for the long posts (had to break it into two since VB wouldn't let me post more than 10,000 chars), and sorry for carrying on a pissing match on this board, even though I wasn't the one who brought it here. Finally, Daewoos, it's kind of silly to PM me with "consider yourself owned" when all you did was twist my words around (unsuccessfully) and make a fool out of yourself in this thread. I PM'd you for a reason... I could've easily started another thread over on b15sentra, but chose to talk to you man-to-man. Somehow I just knew you'd pull some crybaby nonsense like this... hopefully some of the more knowledgeable members can set you straight as well now that both sides of the argument are out in the open.

Take care now! ;)
 
yea the stock bov/divertor valves leak boost once you turn it up past a point. i dunno what the max psi is for the msp's but i thinkg for 2g dsm's its aorund 13-14, just a few above stock. so a bov is a good mod.
 
I just wanted to prove you wrong.

You never stated that the MSP's engine can take more boost than the Specs, but I've stated that over and over and over again.

IT's obvious. The Spec's engine is only good for 7psi, which will still put like 280 whp.

The MSP is around 10 if you wanna keep the tranny stock. (from what I've gathered but I could be wrong) and you were arguing that the tranny could handle alot of boost.

10 psi is ALOT, but that's nothing over stock, 3 psi...which if you were PAYING attention to the b15sentra topic, we were talking about which car could make the most whp without switching out internals and keep it as a daily ride, and the spec v won out, just because of displacement, and we can STILL turbo the engine, while the protege's tranny/internals are almost at it's max for daily driving reliablity...which you were arguing against. But then I said you should probally start by replacing the piping and I/C on the MSP, to remove any bottle necks that the stock piping might have (which there seems to be)

But I don't think too many sane people are gonna throw that much money into a FWD car to make that much power.

I made this thread to just show you that the internals/piping will NEED to be replaced if you wanted to start doing some serious boost to make like 280 whp.

Make your points more clear, which you never, you just state "Mazda left the internals stock because they thought they were good enough" Good enough for what? Since we were talking aobut high powered stuff, I assumed you ment good enough for high levels of boost.

Didn't your english teacher teach you to be more discriptive when you write?

oh yea, and you can't even spell my nick correctly either...moron, can't even read.

and no s*** nissan isn't gonna be making a turbo spec v. I never said they would, I just said, the MSP's engine is like taking a protege and throwing a turbo, which would be the exact same thing as taking a spec v, and throwing a turbo on it.

and no...the spec can run 7 psi reliabily with proper engine management. Travis has already discussed that.

Man, you have very bad interpertation of words, and then you also have bad writing skills, leaving holes everywhere.

Yes, the MSP's engine is perfect for the boost it is taking STOCK. but if YOU were paying attention the thread was about MAKING power on stock internals, which past a certain point the MSP max would probally reach it's max before the specs. Since it's estimated the Spec can do about 200-210 whp N/A then throw a mild turbo or supercharger and you're easily in the 270-280 whp range with good engine management.

I'm pretty sure the MSP's tranny would blow around 240 whp, as a daily driver.

240 whp on a FWD car is still insane...

But I guess you wern't reading, and you missed the whole point about the last thread and which is why you're arguing now, which your argument was lost, since you wern't even on topic now.

And let me ask you a question? Have you SEEN the Spec V handle against an ITR? Have you driven both cars? I have and they handle pretty damned similar.

and YES I have stated many times the MSP will out handle the Spec V it's more than obvious. Learn to read EVERY WORD, and not skimp out on what everyone else is talking about.

yeah when the bov leaks, you get a loss in hp. so a pull type bov (hint hint ssqv) is in order. with the msp, our bov leaks even at stock boost. so a pull type would be in order. some may say that a pull type is overkill on our cars which run low boost, but i say, what if you wanna turn it up.
 
This is strictly for nyisles

Finally someone who knows :wtf: they are talking about

I consider your posts on top of mine E-NUFF SAID!!!(bowdown)
 
hmmm...nyisles....seemed to misunderstand my posts.

Let me explain, the thread was about a Spec V engine vs an MSP engine.

Keeping stock internals, which one theroitically could make the most hp, without having to change anything of the tranny or engine.

Well, alot of us started out by saying it would be the spec, because we can make alot of power N/A and still throw on a mild turbo at 7 psi and our tranny would take it, and so would the engine with power engine management.

Then some people were saying why the MSP wouldn't beable to be built up as most other stock turbo cars out there.

And we stated if they wanted to do alot more boost on the MSP, the stock piping and intercooler are quite the bottleneck. And the engine/tranny were left stock from the normal protege, and (back to the topic of power) the Stock protege's tranny we estimated for a daily driver would probally max out around 240-250 whp, which we know by talking to some of the sentra's turbo experts, the Spec at around 7 psi with proper engine management should probally pull off 270-280 whp.

But I think nyisles saw my posts, and thought I was bashing the MSP's engine in it's stock form for not being able to handle the boost it produces stock. Which is NOT what we were talking about.

Then we got on to handling, and it's been proven that ITRs and Specs can hang together. and the MSP would be above them, but it wouldn't be a huge diffrence (apparently to him it would be).

In all I think it was a big misunderstanding from both of us. I was thinking he was talking about the MSP internals/tranny was good enough to make more than 280 whp (since this was a thread about msp power vs spec power when modded) and he was stating that it could go beyond the spec's capabilities (or that's how I took it as, but he was talking about it being STOCK and being strong enough for stock) and we argued.

Again it was all a big misunderstanding, and if he's a man, he would admit that too.

But I wish he would LEARN how to spell my nick properly it can't be THAT hard it's D-A-E-M-O-S not "D-A-E-W-O-O-S" cuz I don't know who this "Daewoos" is.

Well, alot of us started out by saying it would be the spec, because we can make alot of power N/A and still throw on a mild turbo at 7 psi and our tranny would take it, and so would the engine with power engine management.

You said, and I quote directly from the thread on b15sentra:

"the upper limits of the MSP is far less than of the Spec v...just because you don't really want to raise the boost of the MSP any more, or you risk destroying the tranny and the engine"

... which I replied was false. Using a "mild" turbo setup on a QR25 isn't going to get you much past 250hp, which is not more than what the MSP can do on stock engine and trans. I also hope you're not trying to say that you can go significantly above stock hp with bolt-ons and THEN "throw on a turbo kit" on top of that, since many bolt-on mods are not compatible with turbo setups. CAI, header, and most cams are not usable in a turbo application. Hell, I didn't even FLAME you with my response, and you came back crying and moaning, and telling me I needed to "do research" when you were the one making inaccurate statements. I will ask again, how many blown MSP engines and trannies have you come across?

Then some people were saying why the MSP wouldn't beable to be built up as most other stock turbo cars out there.

That is a given, and I never said otherwise. You are just giving the MSP far LESS credit than it deserves, which is what I took issue with.

And we stated if they wanted to do alot more boost on the MSP, the stock piping and intercooler are quite the bottleneck. And the engine/tranny were left stock from the normal protege, and (back to the topic of power) the Stock protege's tranny we estimated for a daily driver would probally max out around 240-250 whp, which we know by talking to some of the sentra's turbo experts, the Spec at around 7 psi with proper engine management should probally pull off 270-280 whp.

What I asked several times now, which still has not been answered, is how you came to the conclusion that the stock piping is such a bottleneck. Have you measured it? Have you done calculations to see if larger piping would be beneficial? Just saying "it looks small so therefore it is a bottleneck" is not acceptable. Most Turbo Dodge guys who intercool (or upgrade to front-mount intercoolers) use only 2.25" piping because anything larger is unnecessary.

But I think nyisles saw my posts, and thought I was bashing the MSP's engine in it's stock form for not being able to handle the boost it produces stock. Which is NOT what we were talking about.

... and that's NOT what I was talking about, either. Weren't you just blabbing about how I "can't even read" ? Obviously you're the one with this problem. What I have said numerous times now is that Mazda would not put out an engine that could not handle *a bit more boost than stock* unless they wanted to go out of business from all the warranty claims. Any company who makes factory-turbo cars knows that there are going to be people who throw on a $25 boost controller and add a few pounds of boost to an otherwise stock car... if they sold the car with an engine that would blow running 3-4psi above stock, they'd be setting themselves up for huge headaches down the road. Obviously, Mazda sees the engine as being strong enough to take stock boost plus several pounds more without a problem. Now, as Al Pacino would say... "does that seem CLEAR to you?"

Then we got on to handling, and it's been proven that ITRs and Specs can hang together. and the MSP would be above them, but it wouldn't be a huge diffrence (apparently to him it would be).

I said the MSP would "blow the Spec out of the water" stock for stock, which is an accurate statement given equal drivers. The MSP is simply set up better for track usage out of the box than the Spec-V is, plain and simple. Obviously the "blowing out of the water" statement is in relative terms... this isn't like comparing a Taurus with an S2000, of course.

In all I think it was a big misunderstanding from both of us. I was thinking he was talking about the MSP internals/tranny was good enough to make more than 280 whp (since this was a thread about msp power vs spec power when modded) and he was stating that it could go beyond the spec's capabilities (or that's how I took it as, but he was talking about it being STOCK and being strong enough for stock) and we argued.

Yes, that is more or less correct. I did not say MORE than 280whp, but that's about the range I would figure that the setup's good for before needing to be built up.

Again it was all a big misunderstanding, and if he's a man, he would admit that too.

I don't think there was much misunderstood here... this is the internet, it's very easy to get into arguments that are not caused by "misunderstandings." You made comments about the strength of the Protege's setup that I thought were considerable underestimates, and I called you out on it.

But I wish he would LEARN how to spell my nick properly it can't be THAT hard it's D-A-E-M-O-S not "D-A-E-W-O-O-S" cuz I don't know who this "Daewoos" is. [/B]

It was a subtle attempt at humor, Daewoos. You see, it could be interpreted such that someone of your automotive expertise ought to be driving a fine automobile like a Daewoo, or that ... well, nevermind, that's a whole different subject for a whole different thread. :D

You know what?
