If I decide to go with the precision 1000cc injectors for the 90-96 dsm, will the need to be machined..etc to fit and since im using the AEM EMS do i need to have drop resistors

More than likely won't need machining, but you'll have to determine if your EMS is set-up for low impedance or high impedance injectors. Once you've figured this out, chose your injectors accordingly.

check out my build thread... Im using the precision 1000cc DSM style injectors. THey fit perfectly. just gotta use ca18 o-rings and spacers. Hope that helps. Also big injectors only come in low impedance.

yeah precision has some nice stuff. never tried their injectors though. i can get up to 165lb/hr for stupid cheap. anyone know what cc that is?

Found it. AEM wants high so ill have to get some drop resistors too. And which is better designed for our head the ball or disc type sprayers
