| ok. speed that sounds like exactly what i was referring to anyway. I'll just take the engine I have, bore it out, replace the crank and pistons with m3 parts, then m3 cams, now the intake and exhaust, does that even do anything for me on a NA car? I know if I go FI that it will have a big effect but I'm thinking I'll spend like a grand between those two and get about 10hp out of them. Unless i just go custom exhaust, like tell the shop what size and angles to bend the pipes and MAKE it myself. I'll do the software too. How close will this be to an actual m3 motor? And if I go FI, what would you recommend? I've heard of nightmares once you go FI and things don't work because they're not stock. Thoughts? |
