i'm pulling 251rwkw on stock injectors not at 100% with a nismo rising rate fuel reg (makes a big difference with the stock injectors), walbro pump (paid $100), kkr430 turbo charger running 18psi, splitfire coils and an safc2, it's nice and reliable pulls hard as but i will admit at low revs it's not brillant but more than exceptable good luck with the mods mate
