twin turbo expert question I have a twin turbo kit for my C-5 by a company that I cant mention on here. The turbos are 44mm inducer and 57mm exducer ,T-4 flange .60 A/R inlet ,.68 A/R exhaust. They and precision turbo say they can make 1000 rwhp . But Im not so sure. I will be building a 370 iron block with 9.0:1 comp., 226-226 575-575 on 114+4 cam ,Patriot LS6 heads STG 3 ported 2.08 1.60 . It will be in a 99 FRC vette and a 6 speed. Will these turbos be big enough to run 20-25 psi of boost and make 900 rwhp. Any help will be apprectiated.

No....No....and No again.....that size compressor probably would only support maybe 300-350hp a piece...and that is at the flywheel...and would need to be on a very small displacement (mid to high 200ci) motor at elevated pressure ratios.
thos little turbos would not like 370 ci.

Did those turbos come with the kit or did you buy them yourself? As turbocuda stated, they are on the small side, per your stated measurements, but may still work as a decent street package. How are you measuring the wheels?

Pr* T**bo Syst**. I bought the hot parts and the turbos, wastgates from them at the same time and they said they had cars hit 900 rwhp on these turbos. I was reluctant but I called Precision ,and they confirmed it. They said that with that motor they would be at full boost by 3000 rpm and that these turbos max out at 580 flywheel a piece with the A/R's the way they are on my turbos. I said I would think that I would need something like twin 57mm turbos ,but they insisted that these turbos would be good .
They sound like a te-44 turbo from the specs. they gave in relation to horsepower. IF they are te-44, then they are plenty for what you're planning. To measure the wheels correctly, you must take off the housings. Then give us the exact dimension as shown on this picture, depicted by the blue outline w/ measurements:
