Hi, I've read the stickies and other threads on swaps and conversions but haven't found the answer I'm looking for.

I have a '98 bk with a 2.2L and AT. I am far from satisfied as to how the engine and the shifting of the tranny perform. I understand from FAT (Forced Air Technologies) in Phoenix that from the '99 models, the OBDII was vastly improved over previous OBDII years. It was suggested that I just buy a '99 Legacy but they are not easy to come by here in Phoenix (at least for what I'm looking for).

Anyway, I've been thinking about swapping in a '99 Legacy 5MT tranny with the ecu that have come up for sale. How much wiring work will I have to do from the ecu to the tranny and other sensors? The '99 2.2L engine is also for sale--would it be advisable to swap in the engine too or would it mainly depend if the '99 engine is MAP-based?

(I would prefer the swap in a turbo engine but I know that quite extensive wiring would be required which I won't have the time (or patience) to do and that would be too expensive to have a shop do it correctly. In AZ I'll have to get the car to pass inspection and unless it's done correctly, installing a turbo engine won't pass inspection.)

Any advice and suggestions would be much appreciated! Thanks!

Back from the dead...

The 99 2.2L is MAP based, so same as your car (or should be?). I hadn't heard that the 99 4EAT was any better than the 98 4EAT, but I do know that IPT make an upgraded valvetrain for the 4EAT so they probably know better than anyone if there are any differences.

Frankly, the 4EAT is a sluggish dog of a transmission - it didn't get much better 00-04. 05 was the first year they really made a good auto.

Wow, this thread is really back from the dead. :grin:

Seriously, though, thank you for your input!

My '98 is MAF-based but it's possible half way through the production year that it was switched to MAP-based. I know the my car has side-feed injectors and around June, '98 top-feed injectors started being used.

The '05 trannies were 5EATs so besides the extra gear the trannies must have been much improved.

Oh, thanks for that link to IPT, too!
