Re: what injectors for boosted ls vtec (crxkid24)
the size depends on how much boost your planning to run....also saturated injectors are good for obd1...and obd0 peak and hold are good for....peak and hold injector require the use of a resistor box...or youll put to much pressure on the ecu and burn it out

Re: (crxkid24)
Im running DSM 450's on my LS/Vtec turbo, and we maxed them out while tuning at like 13 or 14psi. If you dont ever plan on upgrading and adding more boost then 550's will be fine. But Id spend a few extra bucks and have them for when I want to upgrade. Its just as easy to tune with 750s as 550s, its up to you though. 550s wold definitely work if you dont want to go over 15psi, they would probably be at like 70% duty cycle max(rough guess).
