I have a D16Y8 in my 88 CRX DX and am currently finishing up my Suspension/brakes upgrades and ball joint replacement. I haven't driven the car much because as soon as i got it i started working on the body and suspension. I bought it with DC Headers, 2.5" exhaust with a stock muffler (will be replaced!) and an intake. I'm running a P28 ecu with a 95 Civic Si Intake manifold.

What i want to know is what mods should i do next? I don't want to go turbo, at least yet. I hear people saying CAM, Pulley's, Port and Polish, etc. But for about $500 which is what i have right now...what can i do that will be the best in terms of N/A.

Also what kinds of numbers do you think i would put up with a D16Y8 I/H/E in my CRX?

THANKS,
Vince

 

High 14s with that setup, and a good driver. I would get a cam gear, fuel pressure regulator, and a cam. You can get a ZEX cam for about 280, cam gear 100, and FPR for about 80 with gauge.

 

How will the idle be with that cam and will it still be a good everyday driver?

This is probably a really dumb question, but what does the new FPR do as opposed to not having one? I'm assuming i have the stock one in my car now but does this increase fuel flow? or allow me to change the flow? or just see how much flow is available?

THANKS,

Vince

 

I have a z6 setup with the zex cam and I/H/E along with a z6 intake mani. I also have an 8lb flywheel, but i love it. Go with the cam. I am also using a p28, but having it chipped soon.

 

Yeah sounds like a cam is the way to go from what i have been hearing. How hard is the install and what other modifications or tweaks will i have to do once the new cam is installed?

THANKS,
Vince

 

High 14s my ***. He will run mid to low 15s at the best.

 

i am running basically the same setup and in the 1/8 im running 9.5s all motor so i dont see how you can say my *** to that.

 

my brother had a 91 STD hatch with d16z6, stage 2 zex cam, 4-1 dc header, 2.25" exhaust, si tranny, OBD1 conversion. the best he could muster was 9.6 in the 1/8, and this was with the car stripped. If you are runing 9.5 with no cam and a pace ******* header, you are a liar.

 

Those are good times for your brother, but we have too, hit a 9.6, not a 9.5 as he said. He didnt hit the 9.6 either, I did in his car, so you want to call someone out, go ahead, but here is the slip. This time was hit with full interior, in a 91 CRX HF.



JFI, usdm4gvtec off this board hit a 15.1, non obd, with IHE, and he had a video for it, so.. Before calling someone out, do some research.

That was befor his motor blew , So yes I could see high 14s with a boltons single cam. usdm4gvtec was in a hatch too.

 

azroth, you are correct, i would almost be willing to bet that you could hit 14s with this setup.

 

I would have to say you might need some light weight wheels, with a decent suspension, and an after market front crosmember to help with the launches. But as long as you dont weigh much more than a ton, and have a good, strong motor. there should be no problem with it.

 

91 crx si, dc 4-2-1, pwo, y8 head shaved 60/1000's, 2 1/4 mandrel exhaust, fpr
b16 t-body the car still has ac and run's 14.60's .70's all day long at sea level.
its all in the driver and a good motor.

 

there are a lot of other factors that contribute to timeslips

its not always "i have bla bla bla bla" and " only ran bla bla"

"so you must be lying!"

elevation of the track has a lot to do with times racing at sea level compared to denver could drop tremendous amount off your time

on that 9.6 run your brother made what were his 60' times?

60' times all depends on the driver and their ability to use their suspension to the fullest

what kind of tires were you running? street, drag radials, slicks?

what was the season and temperature at each track ?

track conditions? when you have big v8 monsters smoking the track the lanes are stickier than if you had an import night and everyone was running lame street tires.

as you can see i could go on and on

but im not

i hope everyone learned something

 

Nitrous all the way. Biggest bang for the buck. Don't listen to the typical "blow your motor" stereotype. I ran a 75 shot on my stock zc for a year and no compression was lost. $450 .

 

Nitrous

Whatever everyone says about nitrous

Tuned properly nitrous motors will last forever, to nitrous

 

either a chiped ecu or a cam,
pulley are not very costly, you can get them used and it will be fine, good improvement in power from the aem kit, you can actually feel it when you drive the car.

hope this help
Kranked

 

The AEM pulley kit comes with two pulleys for the D16...one is for the alternator and one for the power steering i think? So would i just be using one of them on my CRX cause i don't have power steering? How about all these underdrive crank pulleys i see on ebay for like $80, how about those too?

THANKS,
Vince

 

just curious but why did you change the Y8 manifold for the Z6 one? I'm kinda sick of the argument about "blah blah sea level gets better times" its not like i'm gonna drive all the way to the Colorado Rockies to see what my times are in a different sea level environment, i live in this part of the world so my times are relevent to the environment i'm in. BTW high 14's are possible with this setup, but thats just relevent to the sea level i'm at, so it may not be possible where you live

 

i gotta agree with 91civicdxdude, sohc vtec with i/h/e runnin high 14s, my *** it does. unless his car is fully gutted and runnin slicks

I had a D16Y8 with a bored out throttle body, homemade CAI, FPR, stock cat and crush bent exhaust in an 89 CRX Si and I hit a 15.2 with it, and a 9.8 1/8 mile, all on *** tires - 2.2 60' was my best. What's so hard to believe about it? These sohc vtec engines are quick... they're pretty new, unlike old *** ZC's.

 

If you are runing 9.5 with no cam and a pace ******* header, you are a liar.


maybe your brothers an idiot..you should consider that before you call people liars

*sigh*

As another guy already stated, some tracks have better altitude than others, like my track (23 feet above sealevel). With a light car, good tires, and a really good driver, you'd be surprised by what's possible. I ran a guy that netted a 15.5 with a basically stock D16A6 (I/H/E).

 

hmm what is the title of this thread again? Seems to me everyone should just race to see who is faster, because all of this talk means pretty much nothing. I would much rather have a B16 but i would rather put my money to other things. Plus it's more fun working on a car than just plopping in a faster engine and talking trash.

Anyway i want to keep going with what kranked91dx was saying...and hopefully someone can answer my question...

That way i'm setup for OBD1 with the P28, right injectors then all i needed was the dist. I heard the Z6 mani was better too, maybe not?
