I was looking into some engine swaps and have come up with a pretty great sounding swap. Ill be posting up after i finalize the plans but have a few questions about reffing an engine so i dont have to find my way around the smog. (cali regulations by the way)
The block will be the 5SFE.

Can i reff the 5SFE in a 94 ST? Yes? As long as the block is 94+?

Do the heads of the engine affect the reff success? Only if theres a VIN on the heads? Are there?

Does the Drivetrain affect the reff success?

How do i go about reffing if all this works out?

Any input would be really appreciated. . .

ok here is the deal. you can do any swap as long as the engine comes from a newer car and has the same family engine. AWD has nothing to do with refree, if you can convert it, then go for it. Turbo has nothing to do with it. The only thing that matters is the emisions system. as long as all the CATs are in the exhaust and the EGR system is installed and working, then you will be good to go.

there are NO VIN numbers on the head only on the block. and new blocks from toyota dont have VIN numbers so you could say its a full up 3S-GTE. I believe the 5S stamp on the block is covered by the transmission.

here is my beef, if you are swapping in a 5S-FE, i dont see a point of refereeing it. its a stock engine for that car so any inspector is not going to question it. I just swapped a 2ZZ into a GT 7th gen and it looks 100% stock.
