There isn't a lot of data available on these stateside.

IIRC, there was a guy who transplanted one into an RS or Legacy from the Phillipeans here on NASIOC...a good search would reveal his name. He's probably the best person to contact.

FWIW, this engine has historically proven to be much more headache than it is worth in terms of the swapping world.

BTW I've got a GT twin-turbo in the UK. My advice is to convert it to an Impreza style single-turbo.

Honestly, I'd sell it on eBay and build up an EJ257 block with SOHC heads. Slap a GT30R on there, and you're golden. You'd probably be spending around the same amount to transplant the TT, but you'd have 200 or so more HP.

Man, you just can't decide whether or not to sell your car can you?

different is good. just how much time + money do you want to spend. the cheapest / most reliable swap is a USDM WRX one. I dont know if its physically possible to do the TT's in LHD car though.

It *IS* possible, but it will be abnormally rigged.
