FI swap, what all do i need

Featured Replies

ok so i have an 87 subaru gl and i took out the carbed motor and i am putting in an 86 turbo fi motor out of an rx, i put the motor, tranny, wiring harness, ecu, new fuel pump and lines, and i was wondering if there is anything i am missing that i need to get it running.

I'm assuming you grabbed all the intake and exhaust garb from the RX as well.

 

The carbed fuel tank has a smaller outlet than the FI one, and there is not adequate baffling to keep the FI pump supplied with fuel at all times, so you should grab the fuel tank from the RX as well.

 

The RX engine will bolt to your stock tranny. However, if you are going to run the RX tranny, it has a 3.7 ratio in the front diff, and your rear diff will be a 3.9 if you have a manual transmission., so you'll need the rear diff too if that's the case. If your car has an automatic, it will be the same ratio as the RX. You might still want to get the RX differential though, as it has a limited slip unit.
