Z32 AFM - $150 Nistuned ECU - $950 fitted and tuned, or buy mine for $350 and get it tuned for your mods FMIC - $300 750cc Injectors - $500 from Injector dynamics on Ebay Fuel pump - $120 for Walbro That's $3620.00 Like I said, we had 350 at the rears, thats was running 16 psi, we could have gone to 20 ish which would have been around 370hp or so at the rears, so close to 300kw, this was more than ample, and for you, plenty enough to kill yourself from lack of experience
