98 stock bottom end
Most people on here would not tell you not to go more then 150whp on a stock bottem end, although there are plenty of people who are doing it with a good tune and a progressive set-up. i currently run a NX 100 wet shot with tr6 plugs, FPSS, and a msd window switch with stock fuel pump and no tuning. i havnt had any problems and ive been threw about 10 bottles. just make sure you go with cold plugs and retard some timing if you plan to go more then 100. also dont forget the safety goodies like the window switch (a MUST for a M6) and a FPSS is a must for anyone. and a new fuel pump my also be needed. hope this helps.
