I wouldn't waste your time buying an RS1600i.... if you're gonna rip the engine out anyway you'll need to change the mounts as far as I can remember the twin anti roll bar set up has the gearbox mount in it???
Better off getting a good Mk3 (if you can find one) spraying it Stratos Silver, adding the stickers and spoilers and job done- cost you peanuts then- fuck 3k!
Interior wise I'd have thought you'd changed it anyway so who cares about the seats.
Problem with RS16i's is that they just aint fast... the only thing going for them is the looks and thats a taste to be acquired.. personally I think they look amazing..

PS- SILVER IS THE BEST!!!
( Caspian blue I believe is the rarest and also pretty cool )
