Ok i just got my b16a1 installed in my 88 HF crx and here is the condition of the car prior to the race (brand new clutchmasters stage 1 clutch, brand new 7.5 lb flywheel, no intake (still need to get one), stock HF piping with 1/4 inch muffler , 13 inch stock tires, havent changed spark plugs yet, and 350 miles of break in................and i raced my friend with a stock 1995 Acura Integra Gsr with just exhaust. First race on a 1st gear roll he pulled on my by end of 2nd and wasted me by like 3 cars. Then we went on the freeway at 60 and downshifted and got embarrased by like 6 cars. Went one last time from 5th gear and hung till i topped out at 112 and he passed me.

Now should i go back to the performance shop and get my money back for getting me a POS jdm motor or what. My friends told me that i still need to break it in and get bigger piping and crap. I mean the 7.5 fly should be revving quick but it feels slow to get to redline. I here vtec engage normally and everything. Whats wrong with my engine??? Should i give it time? plz help thnx

(btw this is hybrider93's friend)

If it is a jdm motor, then it is already broken in(unless you got new pistons/seals etc.). I would just drive it until I am sure everything is in good working order. What tranny did you get? Ecu? When does vtec turn on? If you are still running old spark plugs that may be the problem...

 

First have you broke in your clutch yet? Takes around 500 miles of city traffic action to break in a new clutch. That's just so you don't destroy the clutch to start with! Second you've got a choke hold with your intake and exhaust! Think intake! There have been dyno tests showing a stock CRX SI can gain about 11 HP with just an intake alone! Think about this also, with a stock motor you still get performance gains by opening up your exhaust with manderal bent piping at the correct diameter. Let alone the fact that you have a B16A. That's like going snorkeling with a McDonalds straw, you can't breath! Hello neither can your engine. So try increasing your exhaust to a larger diameter. I think it should be between 2.25 and 2.5 inches, depending on how built the motor is. So with these improvements to start you shuld see a performance gain.Oh, also it all revolves around the driver.I don't know how well you drive so I can't nock or credit you, but I know there is always room for improvement. That goes for evry body including my self!

LATER-

 

an act unsprung 6 puck. best thing i ever bought on my zc and no break in required

 

Your car is going to remain slow as **** until you get rid of the hf exhaust.
There is no way spark plugs are making your car that slow. The reason it doesnt rev fast, is because its blowing through a straw.

 

You ever try an drink a bobba thai ice tea with a regular straw?Imagine that your exhaust is tryin to suck out some bobba ***** threw a coffe stiring straw.This is my description of whats happenin an why your car sucks right now,get rid of your coffe stiring straw an get a bobba straw.

 

Yeah I totally agree the exhaust is the problem!!!!!!!! HF piping is SUPER SMALL in diameter! Get at least 2.25" piping. Intake will help out but get the piping 1st IMO.

 

stock b16a... stock clutch.. stock dx piping, stock header, stock ecu, gay intake... in a 91 std hatchback, full interior.. i beat my friends 95 gsr with intake, exhaust, and vafc by 1/2 car... in front of him the whole time.. you should at least be able to keep up with gsrs..even with STOCK piping. i usually beat every gsr that i race.

I pulled away from a GSR on the highway, but he got me after the top speed. B16a, full interior, civic hatch....good luck

 

this happened to me,
i put a b16 in my crx, and raced my buddys crx si with i/h/e
on the highway he murdered me, i was in so much disbelief,


got to the track, first thing i did was advance my timing, because i had just replaced the dizzy and evidently it was retarded, 2nd thing i did was remove the exhaust, the previous owner put a cheapy on it with a 1inch tip, and last but not least, i guess i did a shitty job of putting the throttle cable on, so i tightened it up a whole lot, and boom 15.3

his car ran a 16.4 we havent raced on the highway anymore but im sure i could smoke his ***, i smoked a 2nd gen turbo rx7 last night.

 

those wheels and tires are messing up your gear ratios causing you to wine out faster I would go with a 15 for sure especialy because you have a JDM tranny as well

 

The exhaust system is killing you, especially with the cat. If you can't wait for a rematch, I'd say unbolt the muffler and take off the stock airbox (if thats what you're using) and give it another shot, I'm sure it will be a lot closer. When you look at an HF exhaust compared to a regular 2.25 system, the difference is incredible, it matters, that would be my next investment.

 

GET YOUR CAR TUNED !!!! you may also want to get a comperession test run to see what you still have left. did you do all the basic maintanence on the motor b4 you dropped it in.... (seals, belts , oil etc etc)? also you really want to wait the full 500 miles with a new clutch b4 you start trying to race (trust me youll regret itl later if you dont) and yes like the others said get your self an I/H/E setup it does make a big differance.......

 

okay.. read what i wrote above... i have a fully stock b16 in a full interior hatchback... i have no mods.. except a stupid gay intake that doesnt do anything except make noise. i have a cat with stock piping... you should still keep up with gsrs...... you have an HF.. you should at least keep up. check your crompression.. maybe your motor has a lot of miles on it...good luck

 

Maybe you got a LS trans....

 

damn that sucks cause with just intake and exhaust i was pulling on gsr's by at least a car lenth...and i got a 4door

 

your clutch is prolly slipping like mad. adjust it and grand ma drive for 2 weeks.......

 

Hmmm... the best you did in your B16 powered 'rex was a 15.3? With nothing more than a short-ram intake in my 'rex with stock motor and all was a 16.2, and that was my first trip to the dragstrip, ever. I'd say you might want to check everything out, 15.3 seems slow for a B16 unless there's something wrong with it or you're running on REALLY crappy tires and spin halfway down the track.

 

yeah...that does sound a little weak.....i was hitting 151's-15.3's right after my swap was done, with only intake and 2" exhaust....in a 4dr too i might add....you should be at least at mid-high 14's

 

haha...sorry to laugh, just proves my piont that b16's are junk even more

my 91 crx dx, d16z6, full interior, running stock air box, and stock exaust. would make most gsr's with bolt-ons look like ****...

as a matter of fact, only one gsr beat me b4 i went boost...and he sprayed me

D all the way baby

i have a frecking LS tranny, but i have plans so it doesn't matter hehe...........

 

like i said these are the crappiest tires evaR, they arent even v rated tires.

they suck they suck they suck they suck they suck they suck they suck they suck they suck they suck they suck they suck they suck they suck they suck they suck they suck they suck they suck they suck they suck they suck they suck they suck they suck they suck they suck they suck they suck they suck they suck they suck they suck they suck they suck they suck they suck they suck they suck they suck

my crx ran a 16.8 stock, my buddies crx si (same one i raced) ran a 16.2
i would say the tires are my issue,

the point of my post was to point out that he may need to make some adjustments to his timing, and remove his exhaust due to the sizeing,

to they guy that said he needed to tune his car, his car is all stock there isnt **** he can tune.

i need new tires, and new suspension. and i think i will be running 14s

 

A stiffer suspension will definetly help your launch by minimizing rearward weight transfer and keeping the front end planted. I highly recommend the Bridgestone Potenza SO3 Pole Positions as a great street/track tire (it's not a drag radial), I was netting easy 2.0 60's with 195/50/R15's when those were on the car. Some adjustable rear shocks would be a good addition as well, KYB AGX/Tokico Illumina/Koni's whatever as long as it's on the stiff setting at the track you'll be good (I have the Tokico's and can't say enough about them).

 

My damn 99 Si with i/h/e ran a damn 15.3 my only time at the track, with a high 2.3 60, you guys should be running way better times.

 

when I raced a friend's 90 Si w/AEM and exhaust I was always slightly faster w/my GS-R. At the time I only had I/E.
