Just your typical noob question. The reason I ask is because I need to decide on a new power goal. The t3/t04e on my h22(2.4l) is dying so I'm going to replace it with some flavor of GT30 or 35. If it is rational to try to get more than 450whp on 93 octane than that what I'm going to shoot for.

If you have 450+ wph from your h22, what turbo are you using? If you think this is not possible or not recommended then can you explain why?

 

EMS and FUEL are a must and a good tune and anyone can make that

if you motor is stock i would worry about pistons,rods ect as far as if the motor can actually hanldle that kinda motor

but 450 on 93 is definitly doable

 

I made 424 on my b16 with pump gas so I'm sure it could be done easily on a bigger motor.

 

I'm sure I have everything to support that power level, I just want to know if it can be done without needing race gas.

 

i just made 460whp on 93 with a 35r on a 2.0 b18

 

with gt35 and about 15 psi with pump gas you will make mid 400s depending on tune with no probs on a h22

Is it streetable? How often do you drive it?

Why a GT35R? There are much smaller turbos that can support mid 400.

 

so theres more room to upgrade. That would be my guess.

 

i have 420/312 tq on 93 . i beat on it everyday at full boost for the pass 4500miles.

 

I don't have anything to upgrade really for a street car, everything is big and beefy. Except the turbo, which I pushed too hard and broke.

Is there any chance of making the 600whp that the GT35R is capable of on pump gas?

500 is the very limit on pump 93 gas.

 

The only way you could get that 600whp is on race gas.

 

i made 470 hp on my old set-up w/ 93 oct gas...but it was on the boarder line of pump gas...ill be scare to push it to 500+hp on pump...

 

Thats awesome, can you give some brief setup info... motor used,turbo specs.

 

b18c1,84mm bore,weisco piston,manley rod,portflow head,gsr cam,top mount man,t4/t67 bb,etc....that was the first time dynoing the motor when it was built @ low boost...after afew weeks went to high boost after installing the 5 bar..

gt35E half the price of the gt35R

 

Look at torque not horsepower, since horsepower is a derivative of torque and rpm. 300wtrq seems to be pretty safe on 93 pump gas. People have done more and you may use water/meth injection to prevent detonation.

 

400whp is no problem for 93 octane. one of our shop cars is running 435whp on pump gas

Not a chance without methanol injection.

 

Compression plays a very large role in this.

 

Theres a fairly local shop that has done a few b18's lately on 93oct. They were running both built blocks/heads, sleeves, as well as motors with just rod/pistons. They ran 57trims and were making 400-412whp with hondata and ~22psi.

Assuming the h22 is built right, I can see 450whp on 93octane being attainable. It wont rev like the b18's, but it will have much more torque to help the HP number.

 

Does anybody else suggest using a GT35 for this goal or can it be done with GT3076 or smaller?

I wouldn't want it any other way

 

Here is a pump gas b16a with a gt35r that I tuned. 100% daily driven.




Here is a h23vtec set-up that I tuned as well. We hit 434 on pump gas then decided to run 110 octane. Unfortunately we couldn't boost more than 21psi.



So to answer your question, 450whp on pump gas is feasible. It's all in the tune.
