Okay, so I've been doing a bit of research since my last post in this forum about a year ago. To refresh your memory I'm in a 99 Legacy 2.5GT 4EAT, currently just a K&N panel filter, will be de-snorkling as soon as the flood season is over.
I've decided to forget about dropping a EJ257 into my car, would be too expencive on all fronts, so i'm thinking of buying a new EJ22T block from xcceleration.com or getting a front clip from a wrecked car or engine tranny combo from ebay.
I DO need to upgrade my 4EAT to handle upwards of 280HP even with a heavy tranny oil cooler.
my question is, will my ej25DOHC heads match to this block, and would it show anymore performance than the stock ej22T heads? Or if anything should I put the STI heads, or a set of ported heads from Cobb or Xcceleration?
Is there anywhere to get performance internal parts for the ej22t like cams and pistons in america or will i have to go to australia or japan for my parts?
I would be building this from the ground up and don't know of anywhere in florida that I would entrust my subaru to except Mastro Subaru but I doubt they would be willing to have my engine sit in their bay for months on end being worked on, and I seriously doubt they have the equipment necessary to propperly tune it the way I want it done.
I still want it completely streetable and want to focus on the engine being extremely efficient. lightweight pulleys, wide open single-cat exhaust, just trying to upgrade anything that could help free up power without burning more fuel.
Yes i realize that racing my car doesn't help with the fuel efficiency, but anything that I can do to make it easier for the engine to work, the less hard I have to push it, the longer the engine runs.
I want to make this thing bullet-proof.
Last question was, would it be easier to just put the new Legacy 2.5 turbo engine into it? find a new or used engine and tranny combo and upgrade the turbo, exhaust and engine management AND that dinky little intercooler that comes on those. hopefully I'd be able to find just the engine, no turbo, exhaust, intake, or intercooler
Is there anywhere that would buy a used EJ25 with 130,000 miles on it? LOL
