custom hybrid turbo questions
Hi guys, i'm just about to make the switch to a single turbo setup, and i've investigated a few different options. My stock twins are toast, so while the build is not necessary as this isn't a daily driver, it's still weighing on me.
I have a question for those with lots of single turbo experience...
i've contacted a somewhat local turbo specialist that does rebuilds for both street/stock setups, and also for road course / drag race setups. His recommendation was the following for something with good response, journal bearing, and linear power.
TO4B/E hybrid turbo using a 50 trim E compressor wheel in a B housing.
because it's a hybrid setup, i'm not sure where to find compressor maps for something like that. i'm not completely compressor map illiterate, but I don't have anything to compare it to. When i contacted him I asked him for something similar to a Garrett 35/82
It'll be going on an HKS cast manifold and using an HKS 50mm wastegate.
What can I reference that to?

What he suggested was basically the go-to inexpensive hybrid for turbo swapped Hondas and the like. It's very common for a 4 cylinder. It's not going to make more power than the stock twins unless you wind it out pretty good. Since he said "hybrid" he probably meant a T3 turbine housing and T3 turbine wheel. Usually the stage 3 T3 wheel is used with that hybrid on a 4 cylinder application. A single turbo FD for most applications is the equivalent of a small to medium sized single turbo conversion on a Mk IV Supra.
The Aspec "GT3574" is a hybrid in the loose sense of the word. It uses the GT35 wheel with a larger turbine wheel.

The 50-trim compressor is very small for a rotary. A 57-trim with properly sized exhaust size will spool well and is good for mid-300 whp. The 60-trim is a great street turbo.
Sounds like your guys isn't up on rotary turbo sizing. As has been mentioned, what works well on small piston engines at a given power level will be undersized on the rotary. I agree with the above. Contact A-Spec or Turblown. They will get you exactly what you'll want to meet your specific needs and they will support their products after the sale.

I've used a 50 trim on a 2 rotor, made 320rwhp around 15psi.
To4E 60 trim with a P trim wheel in a 1.0 housing will give you a V8 torque curve. Shoot straight up at 2500/3000rpms and stay flat to 7000rpms, and then slowly trail off( not a sharp drove however).
