had the pleasure of seeing / hearing an e46 c325ci that had been converted with a Pontiac GTO 5.7-liter LS1 V8 !!!! making it a 357!
didnt get a chance to drive it but maybe next time
is featured in full here with more pics and vids
cant tell you the feeling it was seeing feeling the pure power in that and only £500ish a year to insure with 9 track days !

so if you see it on the roads dont laugh at them for sticking their own stickers on the back and try and race/pass it, you will be left with egg on your face
