are there any othere parts that I need when installing DSM injectors on a 92-95 DOHC ZC in an EK

 

They won't fit perfectly into the stock o-ring seats.

You basically have two options:
- dremel out the stock o-rings on the intake mainfold to fit the larger injectors better, and then place fuel rail on top and screw them into place.
- buy the o-ring seats from an eclipse (heard they aren't cheap..have not looked into it though)


I went the first route, while i didnt have a perfect sized dremel bit, i was able to bore them out just enough to fit the tips in snug so that i could screw the fuel rail down on top to clamp them down.

 

also, if they're peak and hold, you'll need to get a resistor box.

 

OK maybe a better question is: what injectors require the least hastle and perform best?
and what do i need to install them?
