alright guys i have a few questions about injectors. One of my friends is selling me some new injectors for a dsm. they are 440cc and i was wondering if they will work our cars. and whats the difference between low and high impedance injectors. what would be the best for a turbo car?

 

just buy the right ones spend money get right stuff

 

yeah i understand you but for what you get. but im just wondering the difference between low and high impedance injectors. does anyone know about this?

 

the more power you plan to make, the bigger the injectors you need to feed fuel to your engine. but they need to be properly sizeds because if they are too big, you lose fuel pressure.

also, with injectors, make sure they fit properly, or you get a fuel leak...and BOOM burst into flames.

 

Did you ever find out if these will fit? im curious as well, my friend said he would give me his out of his old 92 Tsi. I could make good use for them if they fit. I have 410cc right now, and he said that they are denso injectors, im just wondering the same thing, fitment and voltage? moving from 410 to 440 i could support 10-11 psi regularly, instead of 7.5

 

Actually 440's support about 275 WHP. Boost pressure is irrelevent since you can make the same power at 7 PSI or 10 PSI depending on turbo size, specs and efficiency. DSM injectors would need to run an injector resistor box or run a Hydra standalone which allows use of low impedence injectors.
