Hello Everyone, I need to replace the fuel injectors on my 5.0. Should i replace them with factory injectors. I would like to add some power but dont know if i can do that with the injectors. Any help would be greatly appreciated. Thanks Bozman 777

 

Unless your modified for ALOT more airflow thru the engine then stick with the stock-flow injectors. My engine still utilizes the stock 19# units and is all I need. An adjustable fuel pressure regulator will give you some flexability in increasing potential fuel flow but unless you plan on modifying heavily then stock pressure setting is all you need. With an adjustable FPR you can probably increase potential fuel delivery by about 15%. With an essentially stock engine turning up the pressure or swapping in larger injectors will only cause problems.

Agreed.

The injectors are just part of the solution to bigger power.

Everything has to stay in proportion. If you increase the fuel flowing in, you have to increase the air to match. To do that you may need a fatter cam, head work, intake porting, exhaust upgrades, mass air...
Not to mention the fuel pump, lines and filter, AFPR, fuel rails...

It's like a never-ending saga.

Unless you plan to put some more money into the whole motor, just stick to the stock injectors.

 

Suggest you go to Summit Racing and get the FMS 19lb. injectors cited for the Mustang they will work fine in your truck and at only $209 for a set of 8 are a great price.

 

Thanks everyone, i just ordered the injectors. How much difference would a chip and cold air induction make? Where is the best place to buy them? Thanks again!

 

I would take a look at the Diablo Delta chip and buy it right here at FTE. Money back guarantee if the chip doesn't meet your expectations.

Any time you can reduce the temperature of the air charge then you'll pick up some ponies- and economy as well too. Take a look at http://www.performanceunlimited.com/projectmpg
