i was just curious because ive had a few things changed on mine, also just got a simple nitrous kit installed and im making quite a bit of power and its hard to believe so i wanted you guys to tell me what i should be making for these parts and then ill post what my whp is thanks.

adjustable cam gear
ecu governor chip/speed
testpipe
full 3 inch exhaust
option racing fart can
option racing cold air intake
zex dry nitrous kit
cheap no name camshaft



what whp should i be producing with my D15B2 and these parts thanks.

also my top speed and redline are amazingly high as well

CoreyR

150 is my guess

my whp is 132. not sure if thats as good as ill get with my setup. ive never drove a stock d15 so i cant tell if its faster by much or not, i think its good seeing as stock is 92? my redline is at just over 7K and my top speed with just me in the car is 190kph. sound reasonable for what i have or no way?

CoreyR

i know people with headers exhaust and couple of other bolt ons make 130whp. sounds right to me.

3" exhaust?!?!

Thats 132whp with the n20 right?

CoreyR

yeah i was about to ask why such a big exuast. like freaking wrx stis have 3 inch u woulda been better off with 2.25 or 2.5 exhaust.

3 inch exhaust is way over kill for a d15b2 man. what size jet are you using for the nitrous? if your running too much hp and rev it to 7 grand all the time your going to blow it.. but if your replacing it with a new one then i guess it doesnt matter.

imported_dr.drew1987

well this setup was just the best for the money right now until i can get the engine swapped out and im planning on junking it. the 132 whp is with the nitrous. im running a 50 shot of nitrous dry and it only added approx 30whp. im hoping to get a b series in here with the dry kit, i did want a ZC swap but i dont think it would be any better than mine besides the dohc and 1.6 instead of 1.5L. my testpipe was custom made and the 3 inch exhaust was pracctically free it was so cheap thats why i sprung for it. it sounds beautiful. im hoping to get the swap during the winter because i will be bringing it to the st thomas strip in june for spring shootout.

I reallly doubt it.

Your powerband must suck ***** with a 3" exhaust.

imported_dr.drew1987

what do you mean by powerband? like acceleration?

chris_si98

No i dont mean acceleration. I mean powerband.

imported_janz3n

ya.. your probably losing hp with a 3 inch exhaust.. go to car quest and get a stock mid section and bolt that on unless the test pipe is too big to do that then never mind. you need backpressure to make power too.. if the exhaust flows too freely then you lose hp. 3inch is good for a turbo though.

When modding a car, you have to think of all the modifications you're doing as one big mod. Ask yourself, do they work in together? In the case of 3" exhaust, I'm not gonna flame you on it, but you would make more power with maybe a 25% increase in size, so say go to something like 2 1/4, high flow cat, and a quality muffler. You need backpressures when it comes to exhaust, if it's too free flowing you WILL lose power on the butt dyno. Trust me, at least in the low end.

chris_si98

^ whats in your cutlass?

VTEC_Thunder

I expected more with those mods......but then 3" exhaust on a d15 is nuts......thing must bark like a *****! lol.

Dont really like advertising what's in my car on this website, there has been thefts, but it'll run low 15s. Factory internals. Its my summer cruiser, not a racer. Exhaust wise its true duals, 2 1/4" no cats, dual 14" Mangaflow mufflers done by Noyz Boyz.
