So I have my Greddy TT kit coming in next week and unfortunately i am getting the kit without injectors. I have all bolt ons but still stock internals so im not planning to run high levels of boost (for safety issues obviously). Prolly8-9 psi tops for high boost, and i'd say about 6 for low. Im not really looking to exceed 400whp. With that said, im looking to figure out what size injectors i should run. I was told either 440cc or 550cc. Which would be the better route to go with? This car is a daily driver as well so i dont want it to be dumping fuel, but when I need the extra fuel i want it to be there. I dont really plan on running return lines if i dont have to and i dont want to run into idling issues either with large injectors. Does anyone have this set up on their daily driver? and if so what size injectors did you use? Also what would be the best place to order the injectors? I found some 440s for about $475, but im not sure if that is the "usual" price for what they would be. Any input would be appreciated.

Thanks

 

I think greddy sells their tt 18g kit with 440cc injectors. Why is your kit coming w/o injectors? What are you using for engine management? If its the greddy e-manage in the kit just buy the 440cc injectors. If ur going another route for engine management the 550cc shouldn't be a problem with a proper tune. Hope this helps.

 

I bought the kit used which is why its not coming with injectors (yea dont ask, i said the same thing lol) For e-manage i am most likely going to do Uprev.

 

440's are what comes with the Greddy kit and im still using them with no problems.

 

My 440's ran at 90% IDC @415WHP that was with a fuel return. They 'work' for typical builds but if you are buying injectors there's no reason to cut it so close with 440's given 600's are about the same price. NOW with a UTEC the 440's will idle/start better but with Osiris and proper tune the 600's will be just as good.

 

i would do with DW600cc they sould be a lill cheaper to get no adays
