Looking for some advise on my turbo selection. My setup is a stock 292/th350. I have a clifford intake with a tbi efi kit for it already (not running yet.) This will be on a little cruiser '65 c10. So, not looking for a strip monster or crazy hp numbers. Just a little more pep with good street manners. Is 300-350 whp feasible?

What are your thoughts on these two units?

At first I was thinking about the 70mm turbo but now I feel it might be too big. The 61mm is a t3 frame. Would it be too small even if I went with the larger turbine? I'm hoping to hear your opinions and thoughts.

I know that there's potential for plenty of power while doing a na engine build. Guess I should have asked if that power level is reachable on a stock long block + boost. On a healthy engine of course.

What psi is the next question you will want foraged pistons and reconditioned rods at the least and probable a 1025 head gasket from felpro

Several have posted this link before, but it is very helpful. Just line up engine size and hp. It assumes a t4 compressor housing and less than 10 lbs of boost.

This is great! I'm working on the same combo, but for a '65 Chevy II. I ended up finding a HX35W off of a Dodge diesel. It is just going to be a play car for now, so the turbo size will have to do. I'm also doing the TBI on an Offy intake. I ended up getting my cam and valvetrain from Tom Lowe, so as soon as the head is complete, it will be going back together. My engine was in an old bread truck with around 100K on it. No rebuild, but I just wanted the head to be right.

I have the chance to pick up an hx35 too. I'm afraid the turbine is way to small though. It has I believe the 12cm^2 housing which was stock for the cummins application. Adding a bigger 14 or 16cm^2 might help but would add to the cost.
