Lookin' for a set of A4 1.8T injectors that are just a little bit smaller......

Mat Indukts Lambos · 11-28-2004, 03:26 PM

than the green tops (450 cc?) that I currently have. Anyone? 390? 370? 410? Are green tops 450 or 410? My mind is cluttered with too much info.....

I spoke to someone at Deeds Performance about new 448cc injectors which were made for the 1.8t 5 valve. The Injector supposely points directly at the 3 intake valves. Might wanna give them a call..

around 3500 rpms, under mid throttle, pushing right around 1.0 bar of boost, it starts to stumble, & goes full rich. I think the injectors may be part of the problem, and want to swap in another set of different ones to see what changes.

You might need to increase the fuel pressure though.

Did you check the o2 readings when this happens. Might show that the car is running too lean and the ecu just dumps fuel to correct it.

might be the better option than trying to find slightly smaller injectors.

green tops are rated at 440cc/m, but mine flowtested at 450cc/m

It'd be nice to have some other injectors for while I was there, just to play with.
