Ah k, any idea what pistons will fit ie the 2.2 ones or will i have to get customs? Thanks for the help cause there really isnt much info out there on this.
Yeah i hope thats the case Chris32 because the 26 cams would be a cheap and effective upgrade, i might try it on the GTS4 since i have a link and see if it gives any probs.
Yeah, im running 450's from a 4g63 in my rb20 with a link and im having no issues with idle and fuel economy isnt to bad when cruising so i doubt it is your injector size causing the problems.
