Hey guys I have a closed deck h22 with 87 mm mahle gold 9.0:1 pistons and eagle h-beam rods. I am ordering a peakboost kit and want to know what turbo is recommended with 12-14 psi. T3/t4 60 trim? Or a 60-1 or a gt3076r. What power are you looking at around that psi also? Thanks fellas

YARO.

why are you set on 12-14 psi? Whats the power goals and what is the car gonna be used for? I honestly would go with the biggest turbo availale with that setup.

TheRappist

Well I am not sure what psi i would go with because i am not sure how much the motor will handle with that setup. I would like maybe around ~400 whp. (If it cane handle 430-450 then I wouldn't mind that ethier.) The biggest turbo i am interested in is a gt3076r. Maybe a 35r if it can again, handle it.

It is not my daily driver. It is going to be a weekend warrior. Now that I have another ride.

It is already put together, I have had it for 2 years now. And It is time for boost.

I do not post here without searching. There are very few people running stock sleeved h22's with mahle golds. If it was sleeved, I wouldn't even be posting this thread.
And yes, I already read your post saying H22 sleeves arn't the problem, and your buddy made some awesome power with the 30r, which I am most likley going with, but after reading peole saying you wont see that extra gain for the money you paid, I am trying to find out what turbo would be better, then spending extra for a ball bearing

TheRappist

Looks like I'm going to do a gt3076r with I guess 15 psi

TheRappist

How much do you guys think a h22 with a gt3076r with 15 psi would make to the wheels. I am in a debate with someone. I've seen from 370 to 470 on 93 octance. What do you guys think? ~400whp? Thanks

Are you set more on the power goal of 400whp, or the use of the turbo for a specific reason? There are others than the GT3076R that can do the power level that you're looking for. The question is 1) your budget 2) your understanding of Ball-bearing CHRAs, 3) purpose of the car -(Ball-bearing CHRAs are best for endurance racing w/ their wheel design), and 4) the turbo kit that you're using. The reason why people are saying "search" is because you'll then have an opportunity to see a variety of turbo setups that have different characteristics (more torque vs. higher end peak power) on your H22 9.0:1.

There are those here that have used 400whp w/ an SC61, a GT3257, a GT3540, a 60 trim T3/T4, and a Borg-Warner S362. Some are planning to use it for higher output past 600whp eventually, while others want only 400whp on race gas, and drive the car with a different purpose in mind. Look around for the turbo setup to your engine that have the characteristics that you're looking for. (and please, be more descriptive than "I want QUICK SPOOL, and BIG power, but NO lag".. that's not realistic)

I just want a fun car. I have seacrhed for the past 1.5 years, and it is hard to get people to post results with stock sleeves, which is why I am making a thread. I want a fun car that can make around 375-425 to the wheels, if more then thats fine. I am using a peakboost kit and need to pick the turbo.

I plan on running around 15 psi (or maybe I can run more PSI, I am not sure becasue of the setup, I need some help one that one). I was going to do a a gt3076r and trying to get opioions on it.

Telling me to keep searching is not helping. Not many have Stock sleeve mahle gold h22's. I am not sure what psi and power they can handle. I need someone to help and tell me. Not, search blah blah. I have searched for over a year and half, and barley find a hand full of info on it.
It is not a sleveed b18 2.0, with a gt35r with 20psi making 520whp. If it was a B-series, I wouldn't even post.
This is a whole different breed, and need help.

Plan on using a GE intake manifold.
Stock port head.
Stock sleeved bottom
Eagle H-Beam
Mahle Gold 9.0:1
Peakboost kit

Lose the Eagle manifold. We had one on a stock block H with a sc6176e and a miniram 3". Picked up power with the S2 Pro series... Ill look for a dyno sheet. Made around 400 WHP COMPLETELY stock block.

PSI is irrelivant. Pick a POWER goal and go from there based on what charachteristics you want out of the setup... Leave room for future boost increaces as well... FOOD for thought... a H will spool the **** out of a 61mm inducer turbo and have a great powerband. It will only take about 13 PSI or so to get there... YOu can get there (400ish or a bit more) at around that boost level.

Or you could plan on a 57 trim turbo (Or the like) with a bigger hotside too, but you wont have the headroom for future power and the tourqey H makes **** loads of Lowend early with them. Youll have to run alot more boost to get to your goal (20ish PSI) but as mentioned it DOESNT MATTER, PSI is absolute, how many CFM the snail flows is what actually contributes to CYLINDER pressure (Which produces TQ)... THATS what will hurt your motor if not tuned correctly, or the motor is innadeqautely built


Im making over 650 on a stock PORT H head, (Mild bowl work and de casting flashed, but port floors and such not touched dramatically or intentionaly at all.... built otherwise, running OEM JDM cams too)


For 450-600 You dont have to really do **** to the head. Valves and springs/retainers offer piece of mind though.... Stay away from supertech valves... I run Ferrea 6000s/Supertech Valvesprings/TI retainers and have overreved the motor to around 11,500 on a 1-2-3-2 misshift.... Top end was PERFECT.

Only thing that happened was that I broke the oil pump gear


Limiter is at 9K and I flail it regularly... I beat the **** out of the motor... Its been making 620+ for about 3 years (Sleeves and CPs though)

I have Mahle golds and stock sleeves with a 60-1 it is spools about 4500 rpm. Put down 280whp 260tq and went 13.0 @ 112 mph first time out with a street tune running 2.2 60's.

3" down pipe and exhaust with a glass pack. The turbo has 70a/r cold side and 63 hot tuned by me on Ectune with demon.
