I wanted to know what your favorite or "ideal" turbo is for the RB25/RB20 engines. What I mean is, what aftermarket turbo does everyone here favor?

Anyone have an idea of what the largest replacement turbo is for an RB20? By replacement I mean oil, water, exhaust, etc, flanges match up.

I'm talking Garrett turbos here, like the T3/T4, T04E, and similar.

I did some compressor map mathematics one day and came up with a T3/T04E 50 trim as the bast match for my 400hp goal on a stock RB20 motor.

Kinda vague there. What HP you going for / have? Stock RB20 motor? When's it spool?

ME? IT WOULD BE GOING ON MY 2.3L STORKER W/ THE JUN SPEC HEAD (WHEN EVER ALAN GETS IN TOUCH WITH HIS FRIEND), AND WITH THAT I'D BE SHOTTING FOR 450HP BUT NOW I'M GOING WITH A T3/T4 BB FOR THE QUICKER SPOOL BUT COMPARIBLE HP NUMBERS.
