Hi, i've got an S1 thats currently running 235bhp on the standard injectors on MFI setup. I dont really want to converty to cossie management or efi. My mate has an rst with a similar spec engine to mine but he runs porsche injectors in place of the standard ones. Does anyone know what model porsche these would be from or even the part number? I've had the injectors out of his car but there is no part numbr on them?

 

Iv heard off other ppl that the injectors are not the issue. They are more than capable of suplying the fuel but its how accurate they can supply it. Have you thought about a fith injector setup?

 

I'm pretty sure its the metering head thats the bottleneck not the injectors mate

 

Standard injectors are as good as they come, once you reach your fuelling limit a 5th injector is what yoou'll need.

 

Standard injectors are Porsche injectors. The KE system can also be found on really old Porsche 911's, iirc.
