Question N/A to Turbo

okay, multi point question. my 99 Legacy 2.5 GT's engine in getting long in the tooth and i'm considering my options. I LOVE the styling of the '99 and want to keep it. The question is what engine do i drop in? the WRX's 2.2, the STi's 2.5, the '05 GT's 2.5, or something else like an engine from Cobb? Second question, what transmission? do i keep the old 5 speed and rebuild it, or do i get a newer 5 speed, ooor do i get a 6 speed? What about my driveline? should i plan on replacing the entire thing, just the axles, just the diffs? What else should I be prepared for? Can i keep all of this under $10,000? The work will most likely be done by me and my buddy who is a mechanic, in his shop. Thanks all.

Default well

Things I know.
6 speed tranny conversion will put you over that limit if you plan on doing an engine as well.
WRX is 2.0, easy swap hard wiring.
Putting in a newer 2.5 with a newer 2.5 tranny will give you a new car without a lot of headache.
But if you plan on doing a swap and want a power increase, WRX engine is the way to go. Would need a new tranny prolly if yours is getting old, but they can link up(legacy 2.5 tranny to WRX engine). You could do that swap for under 10k no problem.
I really don't think a STI swap is possible without spending a good chunk more then 10k because you basically have to rip everything under the sheet metal out of the old car and replace it with STI parts.

I don't know any specifics beyond those.
Look under the many 2.5 to WRX swaps on this site for further info.

hmm

w/o labor 10k will get you most anything
the physcal swaping is really really easy its the wireing that will kill you

the sti/FXT/LGT swap is still new but has not proven much more difficult than the other swaps .. you have to get the e-peddle instead of buying a longer throttle cable ...

the car has 150,00 miles. it still runs strong with no oil leaks and minimal oil burn. i am leaning towards a turbo 2.5 from an '05 GT but i think its simply an elitist mentality that i have with the desire to have that extra 0.5 liters. the wiring is the part that scares me. any work i've done before has been on old carburated vehicles ('69 bronco, '76 280z). computers tend to confuse me.
