Been out of the loop for a few years. Street/strip Dart block 331 Astro A5...will eventually do the 4R70 swap, had the parts forever. Currently has masterpower 70mm and a 38mm wastegate that i reused from the bolt on 302 that put down 525/520 on 11psi.

What would you choose for turbo and wastegate...size and brand on each for say, 700rwhp minimum, if am throwing a number out? Will bigger turbo require an additional wastegate or get by with just a larger single?

Thanks
