aside from the crossmember and motor mounts what else would i need to make the engine fit and driveable? I tried searching the forum both regular posts and the archived content and all i get is a bunch of stuff about the wiring and fitting aftermarket parts. please do'nt flame, i'm sure there is something in the forums about this but i'm just unable to find it. sorry.

you dont need the r32 crossmember and mounts. its either or. i would recommend mckinney mounts. there is another thread on the fist page giving opinions on mounts so check that out if you want.and ur gonna need a custom downpipe. everything else ur gonna need should be on the clip

other than that, the driveshaft and transmission should all bolt up? on another note, i have a t3/t4 turbo from a past project and i was wondering if that would fit on the stock mani without any clearance problems or such.

rb20det should be the same as the KA. You don't need a driveshaft unless you are doing a auto to manual swap.

As for the turbo it should fit on the stock mani. You'll need a custom Downpipe and definately want injectors and something to control fuel, and also a front mount. Worry about getting the motor in before you worry about a turbo upgrade.-Alex

i was just asking if the turbo would fit because i already have one. if it wouldn't have fit then i would have sold it for extra money for the swap. the turbo was originally for my ca18det but after i installed the motor and started it up i found out my rod bearings on at least on of my rods were bad. after further research it turns out that this is somewhat of a common problem with the ca18det to the point were it'll even ruin the crank.
