Has anyone done this? I'd like to if it all bolts up right.

It would bolt in with a turbo engine crossmember. This allows for clearance of the up-pipe. An existing crossmember can be modified with competent fabrication skills.

 

The best thing to do is swap a harness with the engine, and have a donor car for any and all parts you will need.

 

Mechanically it's bolt in, but there are a few differences with combinations of parts between the turbo and non turbo.

 

There is a difference in engine harnesses between 90-91 and 92/3-94 models

All the turbo swap stuff has been done, well documented, etc.

The real issues is that the 91 is an OBD1 car, and yours is OBD2. If you live in a place with emission testing you'll never pass.

If you live in a place with emission testing you'll never pass.

probably the case for most but some states used to only visually inspect that the CEL was not on and put a sniffer up your tail pipe. if you lived in a state like that you could still pass. certainly not any western or northeastern states i'm sure.

I live in such a state. It's nice!

I was just cautioning him about the OBD2 thing. Although, it's fairly easy to wire for a 2.0 WRX ECU. Then you can tune it, and pass OBD2 with it.

it is nice, there's no emissions testing at all here.

It's true Im a noob... I should have posted this in "retrofitting"
