Cross brand swap feasibility Options

[6gCeliMitch]

Ok guys I've read up on a bunch of your swaps for awhile I wanted to do a full on gt4 conversion from at200 then I thought 1mz swap now I think I've leaned over the edge a little. Has anyone considered the feasibility of an LS swap? I've seen a few gt4 clips that come with the rear subframe and I bet someone out there has just the subframe layin around that they got with a clip. My thoughts on it are there are most likely more ls parts available versus toyota parts and many more tune shops specializing in ls versus toyota. I know custom driveshaft and I'll have to cut a trans tunnel and I've seen guys talking about Tacoma 2wd diffs but not sure exactly how that would work. Also I plan for my backseat to be be taken out and fabbing just a steel box for whatever maybe a fuel cell. Anything I'm missin any ideas?

The gt4 rear end is built to handle a decent amount of HP (or half of it anyways) but it wasnt built to handle 100% of the torque of an LS motor. Neither was the body of the celica, I wouldnt be surprised if you twisted the unibody or ripped the subframes off without some serious modification. Even the gt4 has a thicker floorpan to deal with the measly extra strain the awd 3s puts on the back. No offense but 50% of a 2.0Lturbo is not the same as 100% of a +5.3L V8

The motor probably weighs more, you will probably need to cut up the firewall and driveshaft tunnel, and you will need a custom steering rack.
