I've got a 1998 RS with the auto and I need a 5 speed. I've got an '00 RS tranny and diff, although a friend of mine has a '04 WRX tranny they'd sell to me for cheap. Can I just use the wrx trans and all of its parts for the swap? I've done some searching, although I'm not sure if I've been using the right search terms. Thanks!

Yes! You need the wrx rear differential too, and a manual trans 1st generation impreza (all models) driveshaft.

I read somewhere that the carrier bearing bolts are different? Also, would a forester driveshaft work?

Where did you read that? And I believe the Forester drive shaft is a different length driveshaft than 1st gen impreza

I would spring for a 02-07 wrx driveshaft if you have the money. The u joint was upgraded for the 2002 model year as a slip joint instead of a U joint and is a little quieter and offers more protection from the elements.

The length of the GD/GC 5mt driveshafts are the same? I didn't know that.

The factory 5mt driveshaft I took off my 2000 RS was like you described, it is a one piece with the "slip joint."

I did a complete 2004 wrx drivetrain and everything bolted up perfectly. If he does a wrx trans and diff, a wrx driveshaft would bolt up to that. The mounting points are all the same.

How was it compared to the RS trans considering the different final drive? I don't have an 5MT driveshaft quite yet, but sourcing the wrx one is essentially already done.

Significantly longer gearing. I like the 02-05 wrx (and 06-07 for that matter) transmissions. Great for highway cruising, but your off the line speed will be slower.

I agree with Mike that I'd take the WRX trans all day long. You're at like 3500/4k in 5th gear at 75 and with the wrx trans its more like 3000 IIRC. Much less engine noise in the cabin at highway speeds.
