Turbo E

as of now, i am making 224WHP with a Greddy turbo kit and Hondata S200b with RC 550cc injectors, ARP head studs. all else is stock.

I know the turbo can support up to 400hp

with the stock MAP sensor (limited to 11-12psi)

can this motor with such high compression be able to support 300+WHP?

I will be using 92-94 OCTANE fuel.

my tuner says i am pushing it. this car also has to be my daily driver.

any rational feedback is apreciated.

smartasses go do something else with your time.

I would also say you're pushing it, but of course with good, or in this case EXCELLENT tuning needed, then you can probably run 11-12psi. How long it will last I don't know. Also what psi are you currently running that is making 224WHP? I'm assuming its 6-7 since you said you have a greddy kit.

With over 11:1 compression and pump gas I would not push that motor any harder than about 8 psi on a daily driver.

ok guys. i guess its the end of the road for me.

I'm gonna upgrade my HKS MBC to a turbo XS unit and redyno my car. if i can hit 250 i will be happy.

thanks for the input.

I know the compression is a lil higher on the JDM B18C motors, but I just dyno'ed my bone stock 95 B18C

Oh god before this gets rediculous. PSI really doesn't matter! I thin kyou know that Turbo E 604. What breaks things is WHP. When boosting it's important not to detonate and the higher the compression (GSR's) the harder it is not to detonate. An LS can be safely boosted and tuned to about 280-300WHP safely...it can as has been seen to have 350+ WHP turbo LS's...just they run ultra conservative in fuel AND timing because even one cylinder detonating will either fry the ring/lift the head/break a rod/walk a sleeve/etc... So with a GSR I think (not sure...confirmation someone?) They are a little stronger internally then the LS piston and rods, but not by much.

In the end, yes 300WHP is very doable with a safe conservative tune...you can do even more, but remember you are now testing the limits as a single detonation will end your engine versus a lower HP and detonating you may survive it.

I hope that helps , and remember don't post on what you don't know and have read hear..thats how **** gets messed up

Is this tru?... The turbo that comes with the Greddy kit!

Turbo E

the 18G can support up to 400 hp according to greddy.

and yah i know WHP is the limiting factor. not boost

I cant afford to live on the jagged edge so, as i need my car to goto work. so 250WHP ( = 300crank ) will be fine

lowering the comp via thick HG is definately not an option as I dont feel like killing myself again.

Yes the motor can support around 390 I know for sure with everything stock (exept injectors) I have seen it done on 2 ITR motors in Hawaii. That is also with pump gas and Torco Additive. Now the motor probably wont last long at all but it is possable.

Good luck with your set-up

Could not have lasted very long.

reading comprehension owns me

im runnin 290whp on 93 octance stock 98 usdm b18c1. thats on 9 psi slightly bigger turbo.

ive got a 96 B18Cspec R swaped in my eg with a drag kit pushing 9 psi @ 271 hp with no problems. if you want to hit more than 280 get a 50-70k head gasket to lower the compression and open up the exhaust with a 3" down pipe all the way back and course a good set of "equal length manifold" will put you way over the 300 hp level with tones of reliability. Ill be posting my thread in a few minutes with my setup and some dyno vids.

thanks for the replies, guys.

if anyone else has something to add, please do.

I never said that it would last long. I think his motor did run for about a year and a half or it might have been just a year

Yes, the turbo itself can support that much power...However "greddys" manifold,wastegate & actuator, and downpipe will not....I have tried pushing the 18g turbo to its limits, but its hard to do when the rest of greddys setup is not up to the task...

I'm running 11:1 compression, 93 octane, 265 whp and I beat the **** out of my motor, no signs of any problems yet. . .

correct, i should have mentioned that. the DP included with the kit is FAR too small to make big power, as is the manifold and wastegate. you'll have boost spikes galore.

IMO the kit is awsome for people who use their cars for daily drivers and dont want to worry about breaking stuff, or reliability issues.

if big power is what you crave, look elsewhere. there are plenty of excellent kits.

is your motor the JDM one tho? 10.6:1 compression VS 10:1 (or something like that)

EDIT: AWWWW..My title is gone
