How do my stock intercooled 1991.5 injectors compare to 5x12

Postby Diesel » Mon Apr 25, 2016 8:40 am

I believe my stock injectors are tired. Lots of miles and starting to be a pain to cold start. Either way - I could use a fresh set of injectors. Do the stock 1991.5 intercooled trucks use a 6 hole injector? I'd like to go to a 5x12 as long as its the same spray angle. My stock injectors are 145 or 155 degrees? Thanks guys!

Factory i/c injectors flow 40lpm in air. 5x12, 145 angle, vco injetors flow 55. Therefore 5x12 flow 37% more than stock.

What are your goals? Auto or manual? What turbo? What current mods? Have gauges? How do you use the truck?
