Whats required into fitting an NA box? Straight swap? Ill probably stick to 250 then didnt think of spinning ha. Spins enough now. What do you mean its a diff ball game? What mods would i need to make 230ish? Ive got JAM ecu, HDI intercooler standard ct9 with zizco ramhorn manifold with screamer pipe, japspeed exhaust air filter relication and thats about it engine mod wise.
