Hey, I just got a '94 850 turbo. I got it for very cheap, its in good shape but it has a burned valve on cyl #3 so I'll be fixing that and doing so upgrades while Im there.
I'm looking for basically info on the car from when it was new as far as features, etc just because it would be interesting to read as well as info on good mods. I am planning on upgrading the ECM, the exhuast and possibly doing the port/polish work on the head- I'm researchiong that now. Also anyone know if basically a bigger turbo back system with highflow cat and magnaflow muffler would throw a check engine light and or would one of the upgraded ECMs eliminate the light.
Any info you guys can provide would be great. This is an awsome site by the way.

The best mod is a 3 inch exhaust complete with downpipe, wideband O2 senor bunge, magnaflow cat, dynomax muffler. Browse my earlier posts on exhaust ideas.
