Im buyin tit exhaust, cams, test pipes & utec. what size injectors should i go with. im replacing them next week and if i can go a lil bigger i will. mine are 315cc, rev ups are 350cc whats HR's & what do u think would be ok.


Thanks GT-Z

 

I would save your money. The modifications that you are doing up to this point should not warrant larger injectors.

 

^^^Listen to the man Your not gonna need it. Becareful with all the N/a mods most likely you will be disappointed with the gains when all is said and done with and you would of come pretty damn close to spending as much $ as a Fi kit would of cost
