It has already been done numerous times. Ken Gushi's car being an example.

If you search for an EJ swapped FRS you will find lots.

Meh, this block has already handled over 500whp on two cars on here already. Im not sure I would want to swap an older technology engine, especially with their timing belts...ick. But, whatever floats your boat

i talked to Gushi at formula d about it. It mounts in really close but its a custom trans on it, so i havnt heard if the rs trans is similar bolt pattern. i doubt it but there working on building the fa motor to drop back in when parts are available.

You're talking about putting a motor in a car that was never meant to hold it. The external dimensions of the EJ and FA are close enough that it could physically fit, but engine mounts and bell housing bolt pattern are almost certainly different. Not to mention tuning and the stock gauges probably wont work either. You'll have to ask yourself if that's major surgery or not.

The real question is why. A set of pistons & rods and a turbo setup would most likely be cheaper and easier. And from what we've seen so far, the FA would be the much better choice.

The stock engine on stock internals is holding up to boost better than a stock WRX engine does at the same power levels so far, so going to a WRX or STI engine is a downgrade IMO.

If you want gobs of power, pistons + rods + lots of boost and you'll be plenty happy, and for far less than just the parts required to get either the WRX or STI engine in.

Have the AP turbo sitting at my tuner as we speak.....just musing with you guys,.... I'm sure eventual LS engines will find there way into a FRS/BRZ. What the FA20 lacks most in my opinion is torque,.... the STI engine is torque'er.

it does lack torque but its use of square dimensions, and it only being a 2L will allow it to rev higher after heads start to be built. always useful for all motor race applications
