i have a greddy turbo set up in my rex sohc v-tec . what other turbo will bolt up to the greddy manifold for sohc.

 

IF this is the Greddy T-25 kit than most mitsubishi turbo ie: 16g, big16g, 18g, 20g. and also garett base turbos smaller than a t3 ie: t-28.

 

Wrong! The Mistubishi T25's have a completely different flange than the conventional Garrett T25/T28. You can run a Silvia S13 T25, Bluebird T25, or a Pulsar GTiR T28 on the Greddy manifold. It has a conventional T25/T28 flange.
