Hi Hayden,

Welcome to Twobrutal!

You can use the standard 3vz ecu, standard fuel pump, standard shafts and even the standard Mr2 flywheel drilled out to fit the 3vz!

The only thing you really need is a custom mount. Paul Woods off of Woodsport can supply one of those.

Best have a read of a few build threads on here, it will help answer a lot of questions.

Chris.
