JDM EJ207? (The correct answer is "Yep, rex, you got it!")

How many MPG does net over stock? Will it make power on regular fuel?

probably the same as stock at cruise. needs a tune for 93 because it comes straight from Japanland where they get 98.

+2 for a proper 207 swap. for those that don't speak subaderp alphabet soup, its the balls-out 2.0 that was only available in the JDM race-spec models like the Spec-C. forged internals, huge ports, EL manifold and twin scroll turbo with an 8k redline, all factory OEM. its the only engine that EVER made sense to put in a modern WRX but we got dicked over with the problematic EJ25 because "dumb Americans" want big bore torque at 2,000 rpm in everything we drive according to subaru.

there are 3 problems with a 207 swap, which is (A) you're going to need a harness merge which can be a pain the dick due to the 207's active cam timing, (B) all 207's were probably driven like bats out of hell so you'll want to buy from a very reputable selling and find someone to go through the engine carefully before installation, and © its a 300hp turbo engine that wants to be driven like you hate it, so your MPG will suffer and probably your transmission too. they also require a tune because if you drive it stock its going to detonate like crazy on our 93 fuel because its tuned for the 98 they get abroad.

alternatively, just buy an EJ257 shortblock straight from subaru, take it to a shop to get stock compression, forged pistons put in, and stick it back in the car with some boltons. enjoy your 350-375hp wagon for the next 100k miles.
