Dad's mate had a e46 m3 man that n/a 6 delivered power beautifully. You know, when it wasn't broken down. Dave's nephew just bought a xr6-t out of the yard at midway ford. Dyno at 400rw/kW. Still on p's. Hope he lives to tell the tales.
Not reli a bmw fan but thr 135 is a twin turbo 6pot, 300hp and there reli light.... gd fun. The motors gd for 500hp on factory injectors and internals. Turbos not to much but its engine out to change them lol....
Id contemplated a fg xr6t to replace the skyline but there so damn heavy... 1800kg.... fat sloth
