Nothing really...your just going to have the top end opened up and the only thing you can really do as far as swappable parts would be to buy a set of Cat Cams and put those in. And the last I knew is you still had to have the gears pressed on. That would also require removing the front engine cover to time the engine. Basically, the engine being opened up doesn't help with anything, if you don't want to go 3L yet. Unless the engine is being removed...then I wouldn't bother with the LSD install until 3L time either. Pre-3L I'd suggest headers, y-pipe, cat-back, K&N, Poles Opt. Throttle body, short throw, suspension. But it all depends on where your priorities are. To some guys, suspension is more important than exhaust, and rims are more important than anything...
