got a zex kit on my 01 4.3 s10. right now it is jetted at 75hp, i was wondering if anyone one knew what jets i needed to use.


also what is the fuel pressure on a stock 4.3?

 

Im running 42 nitrous jet and 27 fuel jet. Fuel pressure is 58psi I believe.

 

is that a 100 shot shot or do you know

 

and thanks for the quick reply

 

Depending what website you find your information. Mine dynoed +73hp and +108ft. lbs. torque with those jets, so yes, it is a 75 shot on my truck. lol

 

well mine is jetted at 21/40 and thats what zex says is a 75 but your info is more reliable due to the dyno #s, so it looks like im about to buy jets

 

Depending on the manufacturer, some rate their horsepower gains at flywheel, others and the wheels, I wanted mine to read at the wheels.

I went with a little bit larger fuel jet, just to make sure I would get plenty of fuel.

 

come on chandler,,, just put the bottle feed line down in the throttle body.. Didnt your dad teach you anything?

 

haha i kno i know
