Exactly. I was originally goig to dump an eg33 in my 99 RS,but the prospect of having my dd on the shelf for even longer than it already has has made me reevalute my goals with the car. Hence,I'm going to drop the motor in my 96 obs and turn it into a beast wagon. As for wiring,if you have found a motor,see if the stock harness and ecu come with it,then you will need to splice it with the stock ecu. Elliseast, a member on here is the only local member that I know who has done it,and is my best reference on the subject. Also,on both RS25.com and dirtyimpreza.com look up Jakeachy and his 99 RS w/ an svx swap,he has a lot of knowledge on these swaps,and is another reference point to use.If it's your daily driver and you need it up and running. Just get another 2.5 and drop it in. If you can afford to have a project and have to dink around with it, the 3.3 or 3.0 swap is fine... just get used to reading the H6 thread on nasioc and doing lots of homework on this stuff. If you're lazy you'll have a useless car, if you actually know your stuff and are willing to put the time/effort in, you can pull it off.
That's my line!If you're lazy you'll have a useless car, if you actually know your stuff and are willing to put the time/effort in, you can pull it off.
