what car came with this engine in it? a guy on my friends bmw forum is apparently going to be sticking one into an e30 bmw 3 series.

It was the R32 GTS-4 Attessa AWD? If it came in another car I don't know about it.

i kow other rb series engines came in the glorias in jdm land esp the rb26's not sure if those had the turbo versions or not. but the rb20 did come in the r32 like chrissy stated. those engines can go in alotttt of cars seen some in jeeps iirc and a mercedes. but the best is when its in a 240 ;)
