would this turbo be too small?
hello guys, i'm thinking of selling my hybrid t04e (made 300whp) to go a little bigger. i found a good deal on an HKS log manifold and wastegate and i'm wanting to get a larger t04b or t04e. i seem to have found a great turbo, but i'm thinking the hotside would be too small... i'm looking to make about 350whp MAX so i figure i can get away with a slightly smaller hotside (all the big turbo guys run like 1.0+ from my experience) i was looking for a hotside a/r somewhere in the low 80's, but with my power goals, could i get away with a .68?
here's the turbo:

From what I understand, the size of the turbine will dictate where in the RPM range the turbo starts spooling up. Small A/R, lower in the RPMs. Bigger A/R takes longer.
The size of the compressor housing and wheel is where you look to see how much air flow you will get. .96 on the hot side is not too big for a rotary engine.

with a 57trim comp and a EX .68 a/r you should reach your goal..just look what you did with your small comp. on you hybrid.
here are some turbos with HP estimates...look at the Comp's and Ex. and then look to see how much hP they make

The smallest a/r i have heard anyone running successfully on a 13bt is a .81 a/r on a t04b 60-1, the car is setup for autox.
those turbo estimate things are a little deceiving for rotary engines. for example: a buddy of mine runs a t04b 60-1, with a .64 a/r on his 7M powered supra..it makes 480whp at 19psi. I see rotary guys running the same turbo w/a .96 a/r housing and making 380 or so hp at 17psi...
If you can get that one cheap enough, buy it. If it sucks, just swap the hotside housing for a larger one.
