Turbo size help

[ssrogers]

Ok, I know this is one of the most common post in this section but I have to ask.

What turbo do you think I should run?

Ok, first off, I'm trying not to sink too much money into this car and I'd like to get me a turbo for $300 or less. I was looking around on ebay and found some T70s for 200 to 220, but felt that was slightly too big. No calculations have been done, I'm just going on feelings. After searching the site it looks like T61 or something closer to 60.

Anyway, 1980 Camaro, 2.73 gear, 4 speed manual. The engine I have for it is a 3970010 block 2 bolt main 355 (350, 30 over), with 3998993 heads (76cc, 1.94I, 1.50E), Cast crank, cast rods, hypereutectic aluminum pistons, dual plane intake, Cam from what he can remember is 112lsa, .481 lift, 280 adv dur, dur @.050 is unknown. I roughly calculated 9:1 compression. Blow thru carb and intercooler (thinking about an air-to-water), neither of which I have yet. Want to run no less than 5 no more than 7 and have the wastegates set to 6 or 7psi, probably 7 since I think I'll get a tad bit of bleed off with that cam. Oh and the wastegates will be hooked to the intake or right in front of the carb to make up for pressure drop in the intercooler. I'm going to try not to rev it past 5000, but it'll probably see 5500 every now and then, 6000 on a miss shift. Single turbo.

Umm, I think that's everything.

Goal: 400hp, 400+tq (I don't know that I'll get that, but I don't want to push a 2 bolt too far past that)

Thanks,
Steven
