I honestly couldn’t tell you about the trannys, though if you glance around that Toysport page I sent that might be some help. I just remember the more desirable engine parts were from the celica 22R, but the transmission parts from the truck were beefier (like the stock truck clutch was used at a upgrade on the celica). As for the header we apparently just got rid of it a week ago so that kinda sucks. But like I said a 22R is a tough ass engine, I’d boost it :bigthumb:
