Hey guys I am building a turbo b16a and would like some input. I am looking to run low to mid 11's. 10's would be awsome but im not sure if its doable for me. Chassis is a stock weight 1991 CRX Si minus a couple of things (probably about 2150lbs + Driver). Engine will be converted to OBD1 and tuned.

As of now I am getting/have a Full Race Stage 1 kit, Thermal 3" exhaust, RC 750cc injectors, walbro 255 lph hp fuel pump, arp headstuds, gsr cams, skunk 2 intake manifold, 62mm throttle body, adjustable cam gears, fuel rail, FPR, traction bar and some other little things.

Now I am considering building the engine more to withstand 350+whp but before i do i would like a general idea of what I am looking at.

1. How much whp will be needed for my car to break into the 11's (11.7-11.99)?
2. How much whp will be needed for low 11's (11.0-11.3)?
3. How much whp will be needed for anything 10.xx)?

NO LSD (possibly down the road if its a huge help), on slicks

Thanks.

 

with me still learning on how to drive, in SFWD trim, actually 240 lbs over the min weight,(min is 2400 w/driver, i am 2650) 520whp got me to 10.96. we added 4* timming and got to a 10.72. i am an 84mm b16 t3t67 ho.

 

I ran 11.30@126 with 387whp. B16 in a 94 coupe that weighs 2660 with me in it.

 

250-300whp for 11.'s
350-375 for low 11's
400 for high 10's

This seems to be the average for most cars which seems pretty good. So with my current setup (should be about 285whp) i should see 11.xx.

Now for a b16a to handle 350-375whp what needs to be done?

Crank, pistons, rods, sleeves, valves, valve springs, retainers???

For a B16 to handle that 350-375whp all you need is a good tune. Now if you are looking for a little more life out of the engine you could upgrade the rods/pistons and get a good tune. There were those guys on here not to long ago that made a ton of power out of a bone stock B16 and ran 10's on it with a hurt engine. It finally threw a rod during the burnout but still from what I remember reading it was beat to death at that point and they were expecting it to blow at any minute

I will be going to Jeff Evans who I have heard great things about so I am not worried about that.

Yes you are correct. I have seen people push retarded numbers out of stock b16's but I am interested in keeping it reliable as it will be a daily driver AND driven to the track.

So what would be the next step for reliability after a full tune up and headstuds to handle 350-375whp?

Thanks

i looked him up hes a little to far (4 hours)

 

Hes worth it and can send you a relatively safe basemap to run on if your chipped already to get you there.

totally agree with this

360whp running constant 11.20's 2250 lb 97 cx

 

how about 700whp on a 1800lbs car?

LOL yup

 

10.65 with about 500 hp in im guessing 2650 or so

 

Sounds about right.

I had a straight LS
92 LX 4 door civic,
10.89 @ 130 mph

right at 400 whp.
1.7X 60 foot.

 

This post is making me want to retune my car for more power!! Right now Im making about 315-330whp on 10psi. I want to run 10's on my setup and I believe it could be possible with more power. Not sure what my car weighs but man this post is making me want to go the 1/4 and try to run some low 11's.

 

11.80 @ 122 on stock gsr. 395whp...

True, The traction is also an issue..

 

what sort of horsepower and PSI boost are the stock B16 sleaves good to reliably if everything else is fully built? ive seen into the 500's at like 18-22 psi if i can recall correctly

What kind of trap speeds are you guys seeing with these times?

 

400whp will trap ~130 in eg hatch

 

reading this thread reminds me how much of a shitty driver I am ahha
