I already bought the lsj so save the "its not worth it" im looking for serious help. I have a pcm picked out but im not sure what else im gonna need for this swap. Do I have to get a new harness? Is a new tcu needed? Should I referb my auto trans?

I know its a little stupid to build this but ive always liked the sedan look and love the lsj engine. So im gonna get it in this car. I know down the road im going to need wheel, suspension, and stearing upgrades. But for now im just trying to get the car rolling again. The head gasket on the l61 blew and the coolant mixed oil spun a bearing.

Place bets on if the motor spins the 4 lugs off XD

 

Lsjs don’t use a tcm. You’re going to have to manual swap it also. You can’t put your auto with the lsj. 100% of that lsj donor car has to be swapped to the other car. Inside and out.
