ls1 supra LS1 MKIII supra. This seems like a cool swap. I'm considering selling my third gen firebird and picking up a MKIII supra and dropping in an LSX iron block with aluminum heads. Thoughts? Feelings?

It's not a bad idea. But the 1J can handle just as much as an LS1. I've heard a couple of people going this route though. They said they found a LS1 for cheaper than a 1J or a 2J. If there is nothing wrong with the motor I would say X2 for big single. If it's a turbo motor. If not, then forget everything I just said and hell yes to LSX!!

I agree that the supra forums aren't the best place to go with this type of question. If they are anything like the Z forums, they get a LITTLE defensive about swapping a domestic engine into the car.
Of course if they just wanted a V8 I say go for the 1uz.....its a tough little engine and when you put some forced induction on it, it will lay down some serious HP...not so much NA....not to mention the 1UZ is dirt *** cheap.

The one I'm looking at is an NA 5 speed. It's body is perfect, but the engine seized. The owner's asking for 1000 bucks, but I bet I could talk her down to 800 since she's my neighbor. 2jz I think is way way over rated and it's heavy and doesn't rev that well (peters out at 6800). Plus, an LSX swap would be different and cool. I don't really care what "pureists" have to say because it's my car, not theirs

Actually, you said a LSX block, and if that's the case... do it, f*** the purists.
With the LSX capable of what... 2500hp (albeit advertised) a 2JZ can't hold a candle to it.
I was just envisioning this the other day... a Mk4 supra... LSX block, and a biiiigggasss blower tower through the hood. Hahaha

Why iron?
Boosted aluminum LSx blocks have put over 1000 to the wheels. Unless you are planning well over 1000 hp, I wouldn't want heavy iron in their unless I had to.
Then it would make more sense to drop the big DOHC design made of iron for a lighter aluminum LSx.

the point is this topic has been covered over and over agian on this forum. the mkIII v8 swaps arent anything new...
i say do what you want...either setup is capable of lots of power.

Do what you want. I had a MKIII and that engine is good for about 500 before I think it'd be worth swapping a different engine in and going for power other than the "wow" factor.
