Go for a holset if single, and t3's with the .48 hot side if twin and mostly stock, and if you have a h/c/i package or a stroker I would go for t3's with the .63 hot side, or maybe some t3/t4 hybrids, the smaller mitsu turbos would be too small for these engines, they would be spooling all the time and prolly get burnt up fast.
