So Boosting Our MSP's is not good..??

[DiscreetSpeed]

last i saw rods and pistons were 1300 together.
and to blow up from detonation well......that person should be shot for not knowing how much to do.

not knowing how much of what to do???

last time i checked not everyone here knows how to rebuild motors i fgure once u get the parts.....have a shop instlal them and blueprint the motor ur lookin at a good 3g job if you want it done right.....i rather spend that much on good management and diagonisatics (spellin?)

 

[DiscreetSpeed]

on how much boost to push silly, what else on a turbo car?
ya i agree but when you got a shop at your disposal and a dad that owns it, its pretty easy but i dont have the money(damnit).
but i agree not everyone has that.

well see thats my point, with proper management you can boost alot more on a stock motor......i have seen stock nissan motors put out over 450whp on the stock cast pistons and rods...granted they were built to be boosted but the general knowlegde that if tuned right you can go a long way is still there.....and the forged motor that blew was from a nissan 240sx....the sr20 motor in it didnt have the proper management and it leaned out on him at the drag strip......he rebuilt the project with a stock block and a tec2 management system and is running faster then he did with the old setup.....forged internals are cool....just not before good management....my case in point

Yes forged internals before engine management is ridiculous. Unfortunately, the Protege rods will never feel 250whp and stay put. Still, fuel control is a must on this car if you want it to run nicely.

I can't wait to start tinkering with an SR20, not feeling limited by bolt on mods.

the sr20 is a monster 4cyl motor....nissan put alot of knowledge on it and it shows....like i stated before...there was a race for the most whp from the stock block...539whp was the most.....even though the msp doesnt have any sort of internal work to help the turbo application, u can still work good whp with proper management. i felt the hype of the whole rwd drift scene and stepped out of the nissans....hence me in a msp now.....but i may return in a couple years, right now im gonna work on my msp....later i want to work on a skyline.....i would luv a clean r32 gt-r.....i smell to4r spoolin at 8k rpm

Ahem ..

Been there, done that. Unfortunately I sold the car before I got to do long term testing (or lost my ass anymore on the car depreciating- $7000 in 3 months was enough of a loss for me ), but with a proper tune- they aren't *as* weak as people make it out to be. The motor is weak in comparison to most factory turbo motors though..

yeh i dont assume anyone is gonna take the msp to the extreme....at this point it smy daily driver and will be until i finish my my ba in mech. engineering....in 3 years im gettin a real turbo car.....the list is growing, as to what will replace the msp

but if someone does take it, i would be wellin to bet the block could hold alot.....cant make assumtions until its done......i remeber when i got my 240 3 years ago....it was said the sr20det couldnt get more then 300whp on the stock block...they are puttin over 500 now.....

Joe you know a 5th gear pull on the road at that psi would've shot all 4 rods out the block.

RB is nice. I was considering a R33 GT-R before I found the 180SX. Figured, not only is the S13 cheaper, but I won't worry about it as much in public than with a Skyline. I'm going all-out on the 180 though, if you want, PM me for details.

how the hell did u get 18psi from our pee-wee t25?? had to be blowin mad hot air

Lol- I had done a couple, but not for extended periods- up to like 125-130 and then let off..

Ok here it is, I'm only talking about under load...when it counts. An engine can run 99.9% of it's life but the one time it runs lean at wide open throttle can cause it to fail. Do you think I just say this s*** for the **** of it? The only point of my last post was...

Mazda set it at "Whatever 6.5 to 7.0 Psi" They thought it couldn't handle more. Why would you expect that it would.

You guys are buying a car and overboosting it from what it was designed to be set at. Obvioulsy some of you are having problems and even blowing engines? If Mazda wanted to design an EVO they would have put forged internals and a bunch of really slick R&D into the MSP. Plus they would have charged more $$$$

Relax guy, don't be poopy. If you blow your engine, you will be the only one responsable for it.

With the tsunami of fuel being dumped into the cylinders I have a hard time seeing where this magical "Lean" spot just appears. But hey you are the all knowing, all seeing, Cannuck Tard so I'm sure when Santa Claus drives the Easter bunny home in his midly modified MSP it will just explode like a Mutha Fugga.

 

[yashooa]

yeah, people arround here all of a sudden got together and shitted their pants cause of 2 blown engines.
and i'm sure that people that blew them had more done to them than what they say. pretty sure boost was higher.

it's like a frigin negative curtain has been pulled over these boards cause of some people's stupidity.

Yes, It's like 5 cars have blown out of thousands of cars, one at stock boost no less, and all of a sudden every FUCKTARD in the world is like,"Man dude those MSP can't take more than like 6PSI without total destruction." or "Dude ya know ya gotta have like 12 grand of mods EM,FMIC,down pipe, full exhaust, and some magic carma mods or your just toast dude."
I'm sure it must (sarcasm) have been the lean condition that blew Jecky's stock boost car as well.

 

[Mr. Win]

haha i had to post just cause how ridiculously long this thread got haah next time thread starter talk with someone with turbo experinces like the hi boost guy or linux or spooling people that can be helpful not all these people who have a small idea of whats goign on in thier engine bay.

 

[AutoBox]

i must go out and blow my motor to attain the knowledge needed to explain the concept of not blowing my motor up? ?!?!?!:wtf:

haha i love this guy.
-Autobox i ran my car at 18psi one weekend and had no prods and now its at 15 all the time....tick tock tick tock its a time bomb.

 

[AutoBox]

have u done any management....what mods? its the whp i care to see...psi doesnt show the whole story

 

[DiscreetSpeed]

nah man im stock w/ a cai.

 

[AutoBox]

thats cool...u should get on the dyno and throw some whp up for us.....its not the psi that matters its the actually about of whp ur makin ......cus a guy pumpin 15psi thru a t3 is makin much more power then u pushin 15psi thru the stock t25.....either way i would like to one day disprove the assumetions that the motor is a pos
