I have a 2000 OBW. I'd like more power (go figure)

I have time scheduled with the mechanic to change the rear main seal to stop an oil leak. He's planning on removing the engine.

How much more involved would it be for him to replace it with an H6?

I don't have an H6 engine, so that's another question. how much are engines?

Mine has 162K miles on it.

H6 engines are very expensive. i'd expect $2,000 minimum for a used one in good condition, low miles.

also - being a 6 cylinder, a completely redesigned engine i'm guessing the electronics are not interchangeable. in other words you can't just drop it in, the wiring, and ECU would need work most likely. i'm not positive though, i know of only one H6 swap and i don't know the details on it.

the easier option is probably a turbo, but i don't know how good of an idea that is on your 2.5. those are known for head gasket problems, so all that additional pressure and heat probably isn't a good thing. the non-turbo 2.2's are very easy to install a turbo on though with great results as well.

Since the H6 uses the serpentine type accessory drive belt with automatic tensioner, I'm guessing you might need all the H6 accessories too, PS pump, alternator, a/c compressor, etc.

Sell your car and buy another one with an H6. Or get a WRX!
