Hi I have an s1, currently running a 1900 Cvh, cam, 3" exhaust and a turbo systems chip

I'm gathering the parts to convert to ofam, as eventually once my engine has been tested to destruction I'd like to slap a zetec in and keep my management setup. Bit of forward thinking

Now I know the ofam requires high impedance injectors, and I'm trying to find some high impedance injectors that are matched to cossie greens

I don't want to buy injectors that limit me later but on other hand don't want too large injectors

Kinda narrowed it down to something like these

440cc
Static Flow Rate @ 43.5PSI : 42 lb/hr
12ohm impedance

The only bit that I'm unsure of is the spray come as these have split spray cone, will that make any difference??

I know these are fitted to beemers and Volvo so can be had cheap also

Siemens deka 630cc ?

 

That's what I originally thought, but assumed that they are too large and may cause idle problems etc.

I think cossie greens flow 380cc or similar, they would be idle but are low impedance

 

If the mapper is decent I see no issue with idle.I had them on my cvh and they are now in my zetec turbo.

 

Exactly what I'm going to be doing also.

Cheers for that

 

DEKA 630's are fine at idle even on a 1.6 CVH.
