Help with mods that actually give HP gains??

No one believes me. Evar.

twilght protege has more than just bolt ons. he's got good tuning on a microtech? i forget. and you know once you start cutting wires and soldering you're not longer bolting things on.

notice Redneck's dyno sheets. his A/F past 3k is pretty rich for N/A with the mp3 ecu. If he could just lean that out he'd see plenty gains. thrown in even more aggresssive timing up top.... (inout)

161.99 crank horsepower by my math. (not a math major though, figure it's just ratios)

95 118.38
130 = x
95x = 15389.4

x= 161.99

never bragged about my math though...

Thank you.


I have thought about an MPI to get more HP but am short on funds now.

When I get my next protege5/protege ( week or two hopefully)Im doing the same as last time Na wise. Intake,obx header, headerback exhaust. Very noticeable gains with the header back exhaust compaired to the regular catback. I'll go with the protege garage IM also this time though. Dont know about the mp3 ecu, want to stick with regular gas this time around.

I was told that the protegegarage IM was a single runner design that would work best in FI applications, and that the stock IM (ported and polished) was the best option if you want to stay NA.

i dont know wether i have different stuff on my uk car. but over here people have dynoed at 155 with

injen
obx
nology
and hks cat back

and thats without an ecu reset. im pretty confident my setup witch will be the same apart from the racing beat catback instead of the hks, will be around that figure if not a bit more.

I know what he has. The original poster wasn't specifically looking for what he could do with just a wrench. He was asking about N/A modifications. Engine management is outside of the block so I consider that fairly bolt-on-ish

Cutting and soldering is a basic skill. Tuning the stand alone ECU/ECM is more complicated, but not beyond DIY.

when i put my peformance parts in my car, i actually feel that the car is pretty fast. it pulls hard and everybody that i drive around always has a comment about my car. im pretty happy with the power output. my upgrades are.
obx headers
unorthodox udp
awr side inserts
mp3 ecu
megan catback
aem sri

im soom going to put a thermal spacer in my intake manifold, and take vtcs out. i heard that is going to be a good added gain as well. after that, i think ill be more than happy with a car that is decently fast that gets over 30 miles to the gallon.

 

[Woody54]

i've been looking at the MP3 ECU for a while now, with the mod's that i have already... see sig, do you think that i would notice a gain? and yes gas sucks and all but if i was really worried about that i would have gotten a hybrid.

soon to add motor mounts... by the way(nana)

 

[silverpro5]

I would love that ecu as well, lmk if you find one for me lol

 

[jomoyo069]

how much hp you lookin at gaining from the thermal spacer and vtcs removal?

someone on this forum can reflash the ecu for u.. i dont remember who it is

 

[ProtoType5]

The reflash in on the "other" forum......and yes you can reflash a regular ECU to the MP3 maps, but you absolutely have to have a manual tranny...and yes the gains are noticible and worth the gas expenses....The one thing I've noticed after the MP3 switch is running even more rich than before....I really wish there was a simple AFC out there that would work....

 

[jamesk]

im thinking 8whp? its the help with everythiing else i have, not 8 whp alone. if i didnt have all the other stuff maybe 5whp?

 

[BKJT05]

I/H/E might get you 15hp but I think the most N/A power made is like 140 to the wheels. There is one college guy that has a project car with EMS cams hi compression pistons cam gears and pretty much everthing you can do and putting down almost 200hp but that a whole lot of money probably 2x what a turbo would cost.

Turbo is the only real power adder for these motors!!

Hiboost FTW 260+/- torque

(burnout)

that engine bay is so sweet, as soon as i get my current bills paid off, im taking out a loan and buying the hiboost kit and building my block.

 

[Blake]

Terbow FTW

 

[shane02pro5]

Thanks! You won't regret the investment one bit, but you will also need performance clutch to go along with it.

Warning it is an addiction and it won't stop there!!!

Header and VTCS removal/intake porting are the best bang for the buck. Injen CAI was just a noisemaker, same with the HKS Hiper. Both did look nice though. They helped out a very very small amount at high rpm. Car still pulls very well to rev limiter.

 

[Wishmaster]

I've heard a number of people mention the VTCS removal helps and number of people who say it doesn't or only offers a tiny increase, so most likey an "in your head increase" and decrease in the future reliablity, felxibility and warm up ability of the car. Does anyone have info on the real deal with VTCS and/or dyno maps proving mods to it?

I'm a realist and will not bother doing anything to my car unless there are proven on paper results. I only want to mod items which don't actually change the way the car was designed to work. So far for simple DIY and bolt on's for an automatic... if I go with a combo of a CAI, Header and Catback (still want to keep one cat, which I guess kinda negates what I said above (shady) )... I am guarenteed of some decent results for some fairly easy to do mods with comparatively small cost ($1000 give or take).

So I think I've got enough info and am able to research which CAI, Header, Catback I should opt for in other areas of this forum... so thinkin this is pretty much done??

 

[DeadGeneration]

Also when you sell the car, if you start removing VTCS and changing under drive pullys your may or may not change them back to stock but its alot harder than taking an intake off and putting the stock back on.

 

[ProtoType5]

The Catted Midpipes from various vendors also is a noticble increase over the stock second cat....and you'll keep some emissions cleaning...

I read in Tuner, when they compared a High flow midpipe vs. a Test Pipe, that the difference on an NA application was around 1whp...That's all...
