VVC is still a K series..... While they were fantastic design wise, and made great power for it's size. But it seems they forgot to finish designing it in great british tradition.
The M20/T16 from the Rover coupe turbo would go in without having to spend big dollar on mounts and so on. But the VAG engine will last longer and make more power and better drivability. If it was me, I'd be finidng the 5k for martoons conversion, and If I ever go insane and buy a Rover thats the engine I'd be getting
