Hello there, first time writing one of these, newb but here it goes.

Does ANYONE know if the 3S-GE BEAMS engines have the same exact bolt positioning for mounting onto a car. I've called the Toyota main #, my local dealership, and all those D-bags gave me the same response, "We don't have the specifications for JDM vehicles..good luck on passing smogged." Therefore I was hoping someone much wiser could help a brother out. Does the 5th gen 3S-GE BEAMS (Black Top) engine have the same mounting and bolt positioning as the 4th gen 3s-GE BEAMS (Red Top) engine? All I want to know is if these 2 engines are interchangeable with one another since they are both 3S-GE BEAMS engines and were made relatively within the same year(s).

Reason being..I want to swap out my 99' GT (ST204) engine/components with an Altezza 3S-GE BEAMS engine. Since the JDM SS-III had the 3S-GE BEAMS (Red Top) engine and is the same exact car/conversion from JDM to USDM, I would like to know if the Altezza is interchangeable as well??? If so.....RWD time! Thanks bro(s), someone help a 6GC brotha out

no...3 of the 4 motor mounts are from your transmission, the black top would need the timing belt side motor mount to have the same tapped holes on the block and then maybe you could make it work, and you would need the intake manifold to point the other way, maybe a redtop one might work....but no u cant make your 6gc rwd without hardcore chassy modification.

It can be done, but you'll need a Redtop to sacrifice for parts. You'll have to swap out everything that bolts to the block, figure out a custom wiring harness, etc. For the cost and the work involved, you may as well go ahead and drop the Redtop in. If the extra 10 hp is that big of a deal, then BEAMS isn't the way to go. The RWD conversion is the same story. It's possible, and recently been done, but it's all custom and takes a lot of modification. It's all possibke but you better be really dedicated.
