Any more thought's on this I'm looking to get a set of new injectors. PM if you need to. I'm going to buy a new set in the next couple of weeks. I'm looking for something bigger than the honed out 5x12's I'm running now.

will do hopefully i can get them soon so i can get my truck back runnin again. now just to figure out what budget turbo would suit my app well

I'm not very happy with them (They are not his, they came from another company) . He is going to run through them and fine tune if you will.

so from what i've gathered from most of you is 6x0.16 are the way to go i all ready have 5x0.14 and i want to go bigger soon. i've seen many articles about guys with high powered 1st gens and they all seem to be running 6x0.16s or 6x.018s, so why should 5 hole injectors be they way to go? don't take me in the wrong way but so far no one has really given a good reason as to why 5 hole injectors are better then 6 hole or vice versa. i don't want to spend another $650 on injectors to want to get bigger again.

Look at it this way, Bosch quit using the 6-hole design in '94, even though the angle of the jet did not change. There are a few reasons, the technical term is known as low lift needle deviation. Basically, when the valve opens the needle is side-loaded which causes 3 holes to fire, and 3 holes do not. Also, the 5-hole design suits the offset incline pattern found on the 12v injector/combination. Hole size does not seem to be as important on the VE equipped engines, I believe soley due to lack of fuel quantity.

You went from a 4x0.012" 155° to a 6x0.009" 145°, do you still have the non I/C injectors?

yes why?

---AutoMerged DoublePost---

4x0.012" 155° to a 6x0.009" 145°
the 10* difference is gonna through the spray off how much will this hurt?

---AutoMerged DoublePost---

4x0.012" 155° to a 6x0.009" 145°
the 4 in 4X0.012 stands for how many holes in the nozzle? and the 0.012 is the flow per injection
and from .012 to .009 i will loose 90 rwp? or is this from something else? pump was put on a bench and tested all good i popped all the injectors checked the pattern all good whats the pop psi supposed to be?
