swapping a 92 5sfe into 90 3sfe car - Toyota Nation Forum : Toyota Car and Truck Forums

Is this a bolt in swap? I just bought a 90 with a bad 2.0 motor and rebuilt transmission and I found a 92 2.2 with a good motor but bad transmission. I need to know if everything will swap to the 90 car.

I think the 5sfe and the 3sfe share the same block. It will fit in just fine, the problem will be the wiring and all the electronics.

Use the complete 5s-fe long block, but the 3s-fe manifolds and electronics. It should all just work since it is an early 5s-fe (the later distributorless ones might require some changes). You should even pick up a few extra horsepower with the new motor.

so you are basically saying that you can drop in a 5sfe and use 3sfe intake manifolds and electronics?

yes the 5sfe is basicly a stroked 3sfe... as long as you reuse the head it should be ok

I dont know if I'm getting this correctly. Long block means the the block and the head right? So 5sfe block and internals + 5sfe head + 3sfe intake and electronics would work? Or is it a frankesteined 5sfe block and internals with a 3sfe head and electronics, etc.?

Thats what I was hoping. Both cars are complete. The 90 has a 3sfe with 15K miles on a rebuilt long block and rebuilt auto trans. The radiator blew and it overheated and caused a head gasket leak. The previous owner let it sit in his driveway for almost a year with water in the middle two cylinders before he decided to sell it. Now the motor is locked up. I bought it for $200.Yesterday I found a really cheap car with a running 92 5sfe and a bad auto trans. I wanted to just drop the complete 5sfe in the place of the 3sfe. But if I have to reuse the intake and electronics off the 3sfe, thats ok to. Another option is to use the rebuilt head,intake & exhaust manifolds from the 3sfe on the 5sfe block.

Yes, it all bolts up just fine.

No need to use the 3s-fe head. That would be just as much work as fixing the 3s-fe alone. You just need to use all 3s-fe external parts (intake, exhaust, electronics, etc.). It is the only really easy swap you can do in these cars.

Don't mix and match 3s-fe and 5s-fe heads/blocks. You are asking for trouble there. You won't know what the compression ratio will be until after the motor is put together unless you get it all figured out at a machine shop. Use the complete 5s-fe long block with all the 3s-fe external parts.

ok....thanks guys. I'll be getting started on this project this weekend.

atobe · 05-14-2009, 02:31 PM

ok i'm mistaken again as always charlie knows more than me

stanno · 06-21-2009, 04:24 PM

Yes. You keep everything external to the motor (manifolds, accessories, wiring, injectors, etc.) from your 3s-fe.

I just recently did one of these swaps you must use the 3sfe oil pan to clear the cross members, witch also means removing the balance shaft if so equipped. i used the stock 3sfe manifolds and electronics and even though the car I'm sure would be faster with the 5sfe stuff it makes a big difference. the car i did was a 5spd and i could take out a 2nd gen integra no probem.
