Hi,
I have been looking at threads on this site for years.
I have a black 1999 R34 GTT.
Current mods are,
Mamda GTX3071r, R35 gtr 560 Denso injectors, R35 card type AMF, walbro 255 fuel pump & direct feed,
Nistune daughter board, Blitz intercooler and boost controller.
Had it tuned on 100 octane 367 rwhp on 15.5 psi.
Look to get upgrade ideas
Here is a pic.
