I want install a 4.3 TBI system (ecm, harnes, throttle body, injectos 4.3, sensors, etc) in 2.8L engine.

My doubt is in CFM necesary for 2.8L with this TBI and mixture too rich in 2.8L.

I could job with 7, 8 or 9 PSI to approve mixture too rich?

here in Chile is not easy burn chip to repear this problem. For that my question is simply change 4.3 system in 2.8L


regards

 

you should be able to turn the fuel pressure down on the regualotor.I am not sure if everything will interchange on the 6 cyclinders like V8's but if they do it shouldn't be a problem then.If everything does interchange,set your ful pressure with a guage and make sure if you can get it a inline guage that way you can allways change fuel pressure when needed and too se if your pump is evergoing bad.
