I can think of about 15 compressors off the top of my head that would work fine, but the turbine they are attached to would choke the ---- out of that motor. 4294 for example. |
Re: Turbo Suggestions for BBC ?
you could just run a small turbine with enough compressor size to support the motor but build the manifolds etc to utilize large wastegates (at least 2x) to get the most flow out of them, then the motor will make boost right off the bottom but the wastegates will keep the restriction down to make power

I have had a few bbc/f/m vehicles, and I NEVER thought they needed more bottom end. Every honda or car I have owned under 2L could use more bottom end, but I will always sacrifice that for a good turbine to compressor balance / top end smash you on the highway. Edited for clarity |

IMO run the biggest turbine side you can, that will still allow the spool that you require, this is probably different then the spool you want.

Re: Turbo Suggestions for BBC ?
Its a T4 divided turbine. He's gettin it this week I guess. Its brand new and he's gettin it from one of his buddies for $400 :o. I'm think i'm gonna try to get him to sell it and get something bigger or get another one and run twins. Twin gt45's would get it done.

Or just get him to buy a T6 exhaust side for it.

Re: Turbo Suggestions for BBC ?
Yup, or the actual numbers off the turbo, if it is a genuine garrett.
