Building my own hybrid turbo

[JeanDSM]

Ive been doing a little research about T3/T4 style turbos and im going for the T03 stage 3 and .63 turbine housing and on the compressor side a T04E .60a/r compressor housing but i havent decided on witch compressor wheel.
50 trim?
54 trim?
57 trim?
60 trim?

I got all the suporting mods, fmic, fp, fpr, injectors, and al that...
Im looking for at least 300 - 325 whp on safe boost 18-20psi daily driven , maydbe on the race track 22psi un til i sell my afc and buy dsmlink so i can push around 24psi

witch one is the best for my aplication and the comparison on turbo lag. Ive heard about 60-1 wheel, can i install it on a T04E 60 a/r compressor housing? how will it perform?

For your hp aspirations have you thought about an EVO16G? Would definitely fit your plans and far better street mannors (e.g. less lag) than a full Garrett in the sizes you list.

As for T3/T4s, the 50-trim is by far the most popular due to it's pump gas friendly map. I run mine (bolt-on exhaust housing) everyday at 23psi on 93 octane. Though for 300-325whp, a bit overkill if you ask me

Literally hundreds of threads out there on very similar questions

I choose the hybrid turbos beacuse my cousing bought a Turbo from ebay, not sure was from ss auto chrome, and he gave it to me. I found out thet the only good thing from my turbo is that the turbine housing is a *REAL* Turbonetics .63 stage 3. I didnt trust in the center housing, so i found a great deal for a chra with the repair kit and a stage 3 wheel for $200 brand new from a guy that was upgrading to bal bearing setup, so the only thing i need now is a compressor wheel and a local speed shop sells it for $75 brand new. I got another friend from a machine shop and he build me a mitsu to t3 manifold adapter for free and I already had the oil lines for this turbo.

When i said that my goals were 325whp its beacuse i dont have dsmlink yet and my engine has 145K healty but old. Next summer i will rebuilt the engine with forged internals and ill be pushing over 25 psi expecting over 375whp.
