Help with turbo sizing
Help with turbo sizing Hey guys, I am looking for some help sizing a turbo for myself. But this is slightly different than most threads around here because I have a budget I want to stick to and I also don't insanely high power either. The engine right now is a stock LT1 with a cc306 in it and the turbo kit is a reworked PTK setup. I know the cam is not optimal but its whats in the car for now. Later I will be going to a 355 with about 8.5:1 or so compression, ported stock heads, ported intake, and a 218ish cam. Car will be mostly a street car and run ONLY on pump gas and NO meth. As far as power ultimately I don't want any more than 650rwhp.
I want to stay around a grand or less for the turbo and don't need ball bearings or anything. I do want the best possible spool that I can get and want to keep the rev limiter at around 62-6500.
Right now I have a Master Power big shaft 62-1 t3 that was going to get a .96 a/r t4 housing before it went on the car. The turbo was custom made for a buddy of mine and is slightly larger than a GT4088. I am starting to doubt it being able to make the power I want it to on pump gas.
Any thoughts?

I was kind of thinking that. The biggest reason I bought it was because my friend was going through a little hard time and needed the money to help out his brother. I figured if anything I should be able to resell it for about the same amount I paid for it.
Do either of you have a specific turbo that you would recommend me then? Another friend of mine (Skinnies on here who has a turbo lt1) has suggested 3 different turbos, 70gts, 76gts, and T76. I would love to go 70 or 76gts but I think cost will be a limiting factor on those 3 unless I go used..

T3 tangial(sp?) housing.
Looks like I will be buying a TC76 shortly after the first of the year. Looks to be exactly what I want for right at what I budgeted for the turbo. Is it very big externally? I am just wondering about packaging in the engine bay..
