ok i have a stage 3gt full race turbo kit, and a fulley built b16 81mm 8:1 C\R motor. what do you guys predict full boost will be by?

when i initally started building up my turbo kit i wasnt looking to rev to 10k But since i have upgraded to the full race stage 3gt kit, i now think i am going to have to rev pretty high.

that leads to my next question, what do you think a good rev limit would be with the motor/kit, i dont wanna rev to 10k with it, however if its unavoidable then that will have ot be that.

if the motor is built to handle the RPM's then just keep pushing it on the dyno until you stop making power.

8:1 with a 4088R....your off boost is not going to be fun...

Call up Full-Race and ask them. You bitch and moan in every SSAC/knock off thread about customer service and product quality compared to the people you deal with. Well take advantage of it.

PS: spending money on a fully built motor and not going to 84mm is retarded. 81-84mm at higher power levels is good for 10-30wtq gain at basically no extra cost.

I had a t3/t67 which is standard bearing and in my experience similar lag than a 4088r. Revving to 9600 cured that problem. Any lower and it would fall out of boost between shifts.

The full race stage 3 GT kits come with the GT35R not 40. This is the same kit I am going to get for my Ls/Vtec setup.

b18sihatch

correct it is the GT3582R not the 4088r

i have basicly the same setup that Fullrace shows in their stage 3 gt page, that car made 650whp with the stage 3 gt kit, and it had the 81.5mm bore.

basicly i think bore diameter depends on the person building the motor, at 650whp with 81.5 do you think the extra 30wtq is really going to matter?

at those whp levels and psi levels the only thing that matters is traction and driveability of the driver. other than that anything about 500whp can pretty much kill all, and a 81mm can do that, so in reality the extra 30wtq is irrellivant in the long run. thats just what i tihnk

i alkso wanted something that was more highway orianted, not so much drag.

im running the long geared LS transmission stage 3 clutch,PFI speed traction bar, aftermarket LSD. so its more orianted towards the highway

but i imagine 450whp could still put down nice numbers, altho i think 450+ would be undermining the complete setup

Um, displacement makes a huge difference in performance. It increases VE, decreases stress on internal parts, and makes more power everywhere. People that don't believe displacement is a great thing are just silly. So yes, 30wtq everywhere in your powerband will make a big difference. At 8000rpm thats nearly 50whp. 600whp to 650whp is an 8% increase in power. That's a good increase for no effective increase in price.

b18sihatch

i know that, however, take this inter consideration, the car is a 91 civic si, completely gutted, no AC no Heater core, no interior, it has 2 seats and a roll cage, power MIGHT make a difference when it comes to displacement yes however the weight to power ratio is A TON.

thats like going into a store to buy a 5 dollar cd with 6 dollars in your pocket. you see 10 on the ground and say oh well i already have more than enough for the cd, even though the 10 has no cost to myself.

b18sihatch

you guys are getting completely off topic with this, i choose 81mm thats that.


still diddnt get a answer with the spool times on the 35r on 8:1 compression ratio

b18sihatch

bump anyknow know the spool times i might be looking at with my setup

downeyballz

this guy probly went 81mm because his motor isnt sleeved, in that case 84mm isnt an option.

i had an 81mm 8:1 motor with a gt35r (.82 a/r) and it didnt hit full boost till after 7000rpm. it sucked driving it on the street because the powerband was so small. i hated the set up.

downeyballz

to fix this issue i bord it out to 84mm, went with 10:1 compression, and switched the turbo to a gt3076r with .63 a/r. this motor should have a much better power band and be much more fun on the street.

you should take you power goals into considerration when choosing a turbo. if you only want 450hp why but a turbo that makes 600hp, its overkill and your car will be a dog on the street.

good thread on b16 power
https://honda-tech.com/zerothread?id=1069197

b18sihatch

those are my mininual power goals, i want AT LEAST 450WHP TO 550

b18sihatch

what do you guys think it could run quarter mile?

b18sihatch

well basicly i am looking at the minimual ammount of 450 and would be willing to go all the way up to 550+ so when you take that into consideration, the gt35r is a pretty good match for the setup

That sounds like an absolutely horrible daily driver.

Speaking of which, I found this on another site. GT35 on a B18 at 8:5 C/R.

Would anyone want a curve like this? LAAAAAAAAAAAAAAAAAAAAAG, spin. Things makes gobs of useless power though.

but we are speaking in terms on Drag useage for that kinda car.

even so what would you say a car with that kinda power would run in the quarter?

b18sihatch

highway i wouldnt say a car like that makes bad power, becuase obviously you are starting from a reving motion to higher revs, which wouldnt be as bad as from a stand still with that kinda power.


alot of races i ever see, with the exception of drag racing, at least that arent in a controlled inviorment, are highway races, and with power like that, that much power would kill ALOT of cars out there, thats for sure

downeyballz

your quarter mile times will depend heavily on you suspension & tire setup. its not easy putting that much power to the ground with a ff car. with that said, with a the right set up, a good driver and your light car you should be in the 10's

No one here can accurately answer that question.
