Simply, but effective build list
The nismo injectors are 600cc - perfect for that power range unless your going e85. Also, I lied - It's a link G4 ecu not a vipec (essential the same) that i gave to Paul - i'll ask him if interested in selling it
100,000km service wouldn't hurt either.
Crazy - Nitto/Tomei pump, cam baffels, 8-9L race pan, race pan baffles/gates, oil restrictors turbo/head, catch can, oil cooler
moderate - billet gear replacement, sump baffels, catch-can, oil cooler, 1L overfill
basic - n1 pump, sump baffels, 1L overfill
