im trying to find out what my options are when it comes to upgradeing my injectors in my tezz. ive just commited to a brand new apexi turbo kit which i should have by the end of next week, i guess im going to need bigger injectors so i can get as close to 350 hp as i can. ive heard you can use 3sgte caldina 540cc ones but if so what model do i get them from??? and how much would i be expecting to pay for a secondhand set??? are there any other options i can go for??? when it comes to new ones i wouldnt have a clue on what ones to get..eg high/low impedence etc. any help would be great !!! :)
