Good Day, I'm Michael. I just got a beat up RA22 that has a 21RU engine and a automatic tranny (Previous owner get rid of the stock 20r engine, I don't know why). Will be doing a full restoration for the car in coming months. Saw here in our forum that 3SGE engine swap is possible but with lots of modifications. so here are my inquiries....

1. I can source out locally a half cut Toyota Altezza, 6speed manual tranny. Do I need the whole half cut parts for my engine swap or I can just get the engine and trans only? The price of the halfcut is way to much from a engine/tranny price.

2. Will I be needing new drivetrain/differentials for the new engine? Can you guys suggest what would i get?

Thank you.
