What turbo??? help!
Hi guys, i recently bought a cosworth engine and with it came a turbo that's obviously different to usual fitment as the thing doesn't line up when fitted DOH!
could you guys identify what turbo it actually is. There is some numbers on it: compressor housing: AiResearch pat no 3058787 and on the exhaust side i have only "M4" ??? and the usual A/R number which is 48. any help appreciated guys. thanks.
