On a stock bottom end lbz what would you go with? And with 60 overs would I need an aftermarket cp3, or would it hold pressure?No 40 overs would be fine. But keep in mind that up to 30 overs is a certain price. Then 40 overs and up are going to cost more. You can go as big as 60 overs IMO. The bigger the better for your motor with good tuning.
With proper tuning you will never exceed your stock CP3's ability. The point of the larger injectors would be to decrease PW and timing a bit. This would leave them open for shorter periods to acheve the same results as your stock injectors. With the 4094 and bigger injectors (and a lift pump) your going to be able to exceed 600hp, which is close to the limit for your rods. So tuning will be kept at a safe level.You wouldnt want a MAX EFFORT tune with those mods. Just a 650 tune Max, and that would be risky IMO. You will be happy with 600hp!On a stock bottom end lbz what would you go with? And with 60 overs would I need an aftermarket cp3, or would it hold pressure?

I am just going to have my injectors honed out... And I don't want to exceed 600 hp. Maybe 625 for a very rare drag tune..With proper tuning you will never exceed your stock CP3's ability.

If I was going to reccomend anything it would be the 45 over Exergy injectors but they arent cheap! They will last alot longer than others tho!
Then keep the injectors stock. No need for larger nozzles if you're not trying to make lots of power.I am just going to have my injectors honed out... And I don't want to exceed 600 hp. Maybe 625 for a very rare drag tune..

I just don't want to be running a large pulse width tune... That's why I'm doing the injectors. For safety on the engineThen keep the injectors stock. No need for larger nozzles if you're not trying to make lots of power.
My truck ran very well with 40s and a 4094, but the #3 piston only lasted 6 months. It was somewhere around 630rwhp and never turned down. If you send them out for honing, send the injectors to be tested. You dont want to screw a larger nozzle on an injector that is leaking or returning too much fuel.
Yea I've heard that bigger injectors can help with the lbz piston problems, being that larger pulse with tunes on the pistons are what causes then to go quicker. Plus I found a good deal so why not...Regardless if you don't want a larger pulse width tune...throwing in bigger injectors and running a lower pulse width tune is still the same as running a bigger pulse width tune on stock sticks. Either way the same amount of fuel is being delivered, same amount of abuse is being demanded from the engine and so on.
Yea I agree a larger injector running a lower pulse width is safer to an extent than running a stock injector with a bigger pulse width to achieve the same power..but the end result is the same. But if you'r set on getting some injectors then I would go 40% overs. They will do everything you are looking for.:gearjamin
I though you had a bad injector in that cylinder?Then keep the injectors stock. No need for larger nozzles if you're not trying to make lots of power.

That just magnified the piston problem. The passenger HG was already shot. More fuel and shitty tuning helped it along much quicker. Personally, I would never go over 550rwhp with a stock 4094 on an LBZ+. DP gets too high along with EGTs.I though you had a bad injector in that cylinder?
We are both getting our nozzles done. Should be a fun time :thumb
The injectors will be tested and the nozzles will be inspected/ tested before they hone them out to make sure they are in spec.
Ouch!!!That just magnified the piston problem. The passenger HG was already shot. More fuel and shitty tuning helped it along much quicker. Personally, I would never go over 550rwhp with a stock 4094 on an LBZ+. DP gets too high along with EGTs.
Like Mike said, it's still injecting the same amount of fuel, if not more, at a lower pulse. It is a bit less stressful on parts, but it isnt a band-aid for shitty pistons.
This is a serious question Chris...That just magnified the piston problem. The passenger HG was already shot. More fuel and shitty tuning helped it along much quicker. Personally, I would never go over 550rwhp with a stock 4094 on an LBZ+. DP gets too high along with EGTs.

I wouldn't buy it. I think they are a total waste of money and time.This is a serious question Chris...
If you wouldnt exceed 550hp with a 4094, why even buy it? Wont the stock motor and parts (turbo, fuel, ect...) make 550 anyway? For me the whole point would be to exceed the stock limits...
Like a 4094 with billet wheel? That's what I plan on purchasingI wouldn't buy it. I think they are a total waste of money and time.You'd be much better off spending the money on a real turbo, or stepping up to one of Danville's chargers if you want to stick with a VVT.
zing lol :rofI wouldn't buy it. I think they are a total waste of money and time.You'd be much better off spending the money on a real turbo, or stepping up to one of Danville's chargers if you want to stick with a VVT.
That's what I have. I like it, but if I had to do it again I'd go with compounds, stock/475. By the time you buy the turbo, intake, downpipe, EGR delete tube, etc you are less than $1,000 away from a compound kit that includes all of that stuff. I do have Exergy 45's and they helped quite a bit with response.Like a 4094 with billet wheel? That's what I plan on purchasing
