Hey y'all, I've been wanting to engine swap my is250 cause I wanna make it into a track car, I was thinking a ls2/t56 swap. If y'all know anything about what I need for it to work, especially the AT to MT swap, and if y'all recommend a different combo. Any help would be appreciated.

 

I I believe you'll need to change more than that. Transmission, ECU, Wiring. Etc... even though they're both RWD and 6 speeds auto, they have different Transmission if I'm not mistaken. The AWD tranny fits both the IS350 as well as the IS250.
