no idea on those, but i've used std t2, t25, t3 and garret t34, unless your on a aftermarket ecu i'd steer clear of the t34, t3 is still a little laggy without managment,a t28 bb would probley be best, you need good exhaust gases to spool up, so that getting your head gasflowed by someone with a flowbench.
