and how many quarts/litres to buy.

 

What clutch/flywheel do I need for _______ engine swap...
What clutch/flywheel do I need for _______ trans swap...

*The unconfirmed answer I have found*

two basic clutch arrangements
push clutch/pull clutch

one for turbo imprezas one for non-turbo (cant remember which)

you cannot mix non-turbo clutches and flywheels with turbo transmissions. So match Flywheel and clutch with transmission..

This is all unconfirmed because I have not personally done any of this and I have only found one source so far supporting it.

 

You should have every answer what they think a good answer would be to their own questions so you can take the good ones and use them
