my e36 318is now has a new ecu chip and an intake already very noticable power gain might even be pushing around 160 hp at 6500 7000 rpm dont know what my 1/4 mile time is right now but what do you guys think a lightwieght flyweel and a new exhaust will gain me.. what do i need to do to make my m42 haul some serious ass without a turbo, supercharger or engine swap. i may possibly do that later down the road but this little m42 is fun, may even do some cam work. please tell me what to do to make this car as potent as it can be without a turbo or supercharger.....
