Hi, if i were to upgrade my stage1 Cossy Engine to approx 350 - 420bhp range which turbo should i go for ? I hear good things about the Garret GT series but which version - GT30 ? Also theres regular threads on T34/5/8s but to be honest most of it goes over my head.

Can you post any links up where i can buy a decent one too - i hear the GT turbos are cheap in USA, has anyone imported any ?

Thanks in advance!
