Find a BOP case if you don't already have one. H&R trans mount, may have to shorten the driveshaft, modify the tranny lines and modified gate plate if you are going to use the stock shifter or buy aftermarket. I am sure I probably left something out :D

new dipstick tube , new TC .and likely a new speedo gear or a ratio adapter to calibrate speedo . and a gas station CC . I love my transbraked TH400 on the street and track but be prepared for lower gas mileage vs a 2004r :)
