hey guys.... I am currently running 550 injectors on my GSX with the evoIII 16g, GM MAF, SAFCII and am in process of installing AFPR... I believe that I am over running the injectors based on injector duty cycle on the data logger... near 130%
is it possable to over kill on injector size by buying too large of an injector or is bigger better??? what would be a good injector size 720, 780, 850???? I saw on the exchange that there are a set of 850's, 780's and 720's for sale.... what should I go with??? -------------------- You CAN sleep in your car, but your CAN NOT race your house!!!

The injector size comes down to the control. With an S-AFC I think that you can get a decent idle with up to 720s. Any more than that and you should be chipped or sportin an EMS.

If you get anything 650 -750 I would very highly recommend an adjustable fuel pressure regulator and very precise tuning unless you are going to get an EPROM ECU and a chip for the injectors. Don't even try to go bigger than 750. Everything starts to get screwy at that point. -------------------- GVR4 866/1000 = the perpetually broken car

I might be interested in your 550's if you sell.

Not to hijack but... What are the largest injectors anyone has ran on just a rewire (stock lines and FPR).

QUOTE (spyonu2007 @ Jun 7 2006, 09:49 PM) Ive have always thought that 550's were plenty for a e316g. That being said, Ill hook you up with a set of 720's. Those will foot the bill, and leave room to grow. pm me with info on your 720's.... disc style??? price??? QUOTE I might be interested in your 550's if you sell. I will be looking to sell the 550's upon install of the bigger units -------------------- You CAN sleep in your car, but your CAN NOT race your house!!!
