I have an H22 and I have the turbo kit I pieced together laying in my room. My turbo is a t3/to4E 46 trim, but I see people with 57 trims and whatnot.

Did I go too small for the H22, would I make more power at the same psi (7) with a larger trim?

What kind of whp am I looking at on a stock internal H22 at 7 psi?

I expect 240, but hoping more along the lines of 270+ - but that comes with good tuning

So any advice, tips, suggestions?

Thanks

 

IMO, it is too small

 

46 trim is small but I bet it spools up nice and quick.

Smaller turbo will just require more boost to get the same effect of a bigger turbo.

IMO the smallest turbo I would get is a 55mm trim.

 

IMO it's going to be an AWESOME street car, and by NO means too small. Ideally, for a given setup, and especially in my opinion, you want the smallest turbo you can use that reaches your goals (or just slightly bigger) with efficiency in mind. This promotes fast spool, low end torque, and excellent driveablity.

Drive it before you knock it.

your horsepower goals are low, that turbo will be a good fit. Your low end will be great

 

The turbo might have a tendency to lose power higher in the RPMs. IMO might want to get a bigger trim, but it won't be too bad, just not optimum.

 

the turbine has a much bigger effect on spool and that compressor can easily support over 300. As long as the turbine flows good (stg3 .63 a/r) it will have a nice broad power band.

I agree with sizing the turbo as small as you need to meet your HP and power delivery goals

Just because flocks of people have turbos that support 450whp, but drive around with 250whp does not mean you should.

 

Thanks guys!

Is 270 whp out of the question, or does that seem obtainable?

Keep in mind this will be at 7-8 psi

 

That is easily achievable with the proper fuel managment and proper tuning!

 

a lot of people get confused and think a motor can only handle so much "boost" but in reality the boost is not the main factor, it is how much hp a motor can handle because 8psi on that turbo is a lot diff than say a 60 trim. i dont know how much about H22s but just wanted to add that little info

 

That kind of power out of a stock H22 sounds a bit risky. Be careful on the tuning.

 

i wouldnt do that to a stock h22 , it wont last too long , those motors hate boost stock.

 

Im going for 7 psi, then when it blows, rebuild and more boost

 

I would trade you my t3-t04e .57 trim for yours. Mine is too big for my D series, but would be perfect for the H.

 

I got a t3 with a .42 a/r if want to trade.

 

i HAD a t3/to4e ar50cold-ar48hot on a bone stock h22 and it was def not too small as a matter of fact IMO it was to big specially only using 7 psi i went 7psi to 9 psi then to 12 psi bone stock at 12 psi it made average 310 whp and alot of torque that is the key with the smaller turbos they spool up quick and make lots of torque wich is exactly what you want at 7 psi i would excpect you to be some wher near 240 whp but dont excpect more...and i had the car bone stock turbo for over a year with no probs

I don't think you will blow it at seven pounds. I've been running 10 on my stock block d16z for over a year... It will hold it.

Please enlighten me as to what your experience with a d16 on a T3 has to do with his H22 on t3/to4e? Im dying to know.

Have you ever compared the internals of a D16 to those of an H-series?

Enough said.
