ok.. i want real HP, but dont want to break the bank. i have debated on using a 7m crank. or using a 6m engine. but if i use a 6m when i order parts ie internals. cause i figure the 5m/6m use all same gaskets. i heard the main pully is differnt is that true? and ecu differance is that a problem? and how hard is it to get a 6m ecu?

all help appreciated before i break out the bucks on forged items. and if i left out anything that I SHOULD know tell me!

6M uses all the same gaskets and seals, with the exception of the crank oil seals. The pully on the 6m has the larger inner diameter of the 7M crank. A 5M pulley can be machined to work. Ecu diff's are not a prob, juss need to richen up the AFM in most cases. The 6M ecu comes around here and there....but you honestly don't need it. Let me know if you want a 6M.
