Do they have one there correct for your turbo? Maybe a CWMFS-G-227 or a CWMFS-G-228?

Yes,is g-228.!

Yes it made 650 whp on the English Racing awd Dynojet. That was with 60% ethanol/40% 92 octane pump gas in the tank.
They were using about 70% duty cycle from the boost controller on that run. I had told them that I wasn't interested in pushing it to the ragged edge and that if they got it pretty easily to 650 they should just stop right there, no more dyno runs.

I have the dyno chart and most of the mods all shown in my profile. The "Performance" tab shows what the atmospheric conditions were.

Your turbo, I guess you are talking about the PT&E 6165? Is that a CEA, or a GEN2 CEA, or was it before CEA?
Anyway, I would think it could do 600 whp if you are giving it E85 or even E70, or race gas, with the .63 housing, but I haven't followed the PT&E turbos enough to know what to expect from it.
All I can say is that with my own car, when I was in the talking stages with English Racing, they told me they had never gotten more than about 700 whp from an FP HTA3582, even with full E85 and .82 a/r turbine housing with 3 inch turbine outlet.
On my car, I was willing to give away some top end in order to gain some on the bottom end, and for a more compact installation. So we did some things that were aimed that way. My turbine housing, not only is it .63ar, but it is only a 2.5" turbine outlet, T31 style which is a short outlet, nothing fancy. The O2 housing is only 2.5", but it is a really nice one, smooth, made by Shearer Fab. So my downpipe has a 2.5" flange on it and goes up to 3" diameter about an inch after the flange, and the exhaust is 3" the rest of the way.
The other thing I told them was that I would be mixing 92 pump gas with E85 and probably only running about E50, never full E85 in the tank, which is why they did my final dyno run on only E60. So, you can begin to see where even giving some things away, this turbo had no trouble making 650 on their dynojet, with the .63 a/r housing. Take a look at the rest of my mods though, in my profile. There is a lot of good stuff there.

Yep, e85 (flex mix, but will probably dyno at full e85) and alo t of my parts are similar I'm running 2150s, hks272s, built head/block.. But I'm running stock 2.0 yours is a bit more built with that piston/rod combo, I'm only running h beams with carillo pistons, but like I said this build is only meant for 600.. My trans was built by dogbox performance.. And won't be able to handle much more then that, im sure..

Later when I build for bigger power, I will probably do a destroked 2.1L or something. I like high revving monsters

Sounds really good, flex fuel is so nice. Yeah the transmission and other items in the driveline are kind of the weak points I figure, at this stage!

@gsx tuningart
Good luck with your project! It looks like your project will be a long running one, and has been a long running one already to this point.
Thanks for doing such a nice job filling out your profile page, and your excellent photos.

I uploaded a little language humor to YouTube for you, from non-English viewpoint, that you might get a bang out of, here!

Looks nice!

We Hope that work also!
The man of machine shop,told me that my turbo have big shaft and 360 degree bearings also!
