Hitura Posted July 6, 2012 Share Posted July 6, 2012 So i am thinking of buy a 1992 Subaru Legacy 1.8 STW 4wd and swaping in a 09 impreza wrx sti engine in to it. So now i have 2 questions of the 92 how much power can the manual transmission in it take and how well will the engine bolt on to it? that is all, waiting for anwesers Link to comment Share on other sites More sharing options...
monkeyposeur Posted July 7, 2012 Share Posted July 7, 2012 The transmission may work for a while, but it wasn't made to handle that much power. It depends on how careful you are. No one can say how long it will last. And when it goes out (which it will) you will have to swap in a new one. Of course swapping in a sti trans would be the way to go. Your stock trans is not the way to go. The engine should bolt right on, but that isn't the only thing you will have to worry about. You may need to change the clutch and flywheel since they changed from a push to a pull style clutch. You will need to install a wrx or sti crossmember so the downpipe will clear. Plus you are going to have do a lot of wiring and get the 09 ecu, or go with a standalone system. Do you have the 09 sti engine already? Can you get the rest of the parts (ecu, wiring harness, trans, axles, crossmember, to go with it?) Link to comment Share on other sites More sharing options...

USLiberty Posted July 7, 2012 Share Posted July 7, 2012 Should just buy the whole wrecked car then, or better yet buy a jdm sti engine/ecu/6spd/crossmembers/driveshaft/hubs/brakes and rear crossmember/diff for around 8500$usd. Your trans would snap really quickly then you'd have double the time invested. Do it right the first time and you wont regret it. Id do research but I'm pretty sure you'd have to pull ecm wiring completely out of the donor car and you would need a turbo legacy front crossmember just so the turbo motor will drop in. The exhaust manifold on the turbos require extra clearance on the crossmember. Link to comment Share on other sites More sharing options...
