Forced Induction - t70 vs t76

Looking between both these Master Power turbos. My initial goal is about 400 at the wheels but would like to be able to make over 500 eventually. What do you guys think?

Theres also a guy local that has a GT3788R off a Duramax diesel. Here are the specs on it:
Compressor: 63.5mm inducer / 88mm exducer, 52 trim, 68-69 lb/min flow
Turbine: 72.5mm, 78 trim

the 70 will support up to around 600 whp. just fyi, but why go smaller when you can go bigger!!! and support more in the long run!!!

76 FTW!

I went with a T70 for my stock cube build...and it can support 600RWHP so thats plenty for now... and when I do decide to go bigger... it will be bigger than T76 :devil:

What do you guys think about the GT3788R? Its a ball bearing turbo which would be amazing. Thanks for the replies

what setup do you have? but I vote the t76 because trust me you are going to want to turn up the boost.

yup!!!

A T70 with only a .68 a/r and 15psi was enough to push my 5500# truck to a 110mph trap speed at 5000' elevation. The T76 w/.96 a/r broke the out put shaft on the tranny TWICE, lol.
