Re: Where can I buy good Fuel Injectors?

I know this is an old post... but still on the top of the section so I figured I would add 2cents.

You may want to look into a balanced set of injectors... there is performance to be had with them being balanced together.

Think of it as if you had ONE injector on one side that was lean... but the other 7 where running richer... Your O2 sensor would read that RICH condition and remove fuel... making that cylinder even leaner... This means that cylinder would not be making the same amount of HP as the rest...

Typically you can see as much as a 15RWHP gain from going from Non balanced to balanced.

If you have any questions please feel free to contact me.

I've been looking at the stinger injectors on your site for 6 months debating on tgem not just for the curiousity of better performance but they match my color scheme. Better stsrt putting the money together and get a set!

Re: Where can I buy good Fuel Injectors?

Hello my .02 cents is call Jon Banner at Fuel Injector Connection, the best as i have done some crazy things and he is always there with time to help me out,
call 770-888-1662 or see his web site.
I am not sure of posting rules here but the web site is easy to figure out from my post.

Go to http://www.fiveomotorsport.com/...I purchased the 4 port injectors to replace the stock single nozzle. Much better low end acceleration, smoother idle and about 1.1 mpg gain.

Re: Where can I buy good Fuel Injectors?

After I installed 784 4 hole injectors; made lengthly trip with 2002 JGC 4.0L Select trac auto trans with 3.55 gears and 24570R16 tires.
Jeep loaded with 2 months of clothing and misc supplies, traveled 2000 miles at 70+ MPH and obtained 19.3 MPG mostly highway.
Have obtained 15.9 MPG during local mostly city driving.
Actual mileage calculations, using old fashioned calculator.
I have been very satisified.
