" i mean this is a perfectly fair comparison, both are 4 door m3s with (i would think since BMW is in love with cost-cutting) the same manual transmission. the advantages the f80 has is the CF roof and FI and then the carbon brakes if you wanna throw that in there. it would be just as fair if the f82 and e92 were being compared. but it is obvious that the e9x is the better engineered car.

" Not yet doing a few things like cleaning up the welds making the intake to head gasket better just gotta make the kit a little better the price for the kit is so expensive for the quality of it but at least there's something to work off of and make it better no way in hell am I going to use the stock fuel injectors the guy says you can but I say no I drag race a 11sec turbo car and fuel is everything you run lean kiss the engine goodbye I'm gonna run 32lb injectors a guy from ess tuning told me the car will run fine as long as I use bigger injectors and the FCD on the mass air sensor "
