So, i'm turning up the boost on my greddy 18G. Currently runnning 310CC's. I'm running 8psi but will be running 12-13psi on the day of my retune, I was thinkning of going with like 880CC injectors because next year I will be going with an external wastegate, and a built block + more boost. So i'm trying to plan ahead here, is there any down side to this?

 

Ask your tuner if he can tune them.

Getting ID1000's are fine for your goals for example. Do some looking around into ID, and FIC injectors.
There's a lot better technology out there than RC.

 

I ran precision 1000's on my stock turbo Ls only making 260whp. I had no troubles.

 

It's ok to go with bigger injectors then u really need cause u can always turn down the duty cycle and wen u go more boost just have it retuned

 

considering the limits of the turbocharger and his needs, is it really necessary to go straight to 1000cc? I'm so sorry that I'm rather old school, but the 18G can only go so far, even if he want room to grow as the H-T logic tries to dominate

 

i will be also running 1000's on my stock ls v turbo

 

yea, the greddy 18g will never be able to take full advantage of even 880's

use the rc calculator and pick injectors that fit your needs... unless you plan on upgrading to a larger setup in the future, 880s are pointless

 

I wasn't trying to say get 1000's. Just answering his question with my experience.

 

Understood. You were simply using it as an example.

 

As for my future goals, i'm unclear on them. I could either be going with a totally different turbo altogether next season like a GT30, or sticking with the 18G getting a new manifold and running an external wastegate as I've seen it make 350-400hp on many occasions. For all I know I might just be happy with the potential 280whp I'm projected to put down with my new downpipe and new boost setting of 12.5-13psi.

I dyno'ed 230whp on just 10psi with my 18G on my D16Z6, even my tuner was flabergasted that he was able to produce that much HP safely, apparently i've got a very stout single cam.

My current plan is to run the 12-13psi with ARP studs, new head gasket, 880cc PTE injectors, and custom 3" downpipe..if all goes accordingly I shouldn't have a problem hitting 275-280whp as we all know that the greddy elbow and DP are killing me.

All I had on the day of my first ever tune was a 255 walbro, BnM FPR, and the RC 310's.

 

I would get the ID1000's. Great injectors to tune and will run dang near like stock. Plus, if you decide to go E85 later you have the head room.

 

I don't get the hype behind ID... they are just the new bosch injectors. eBay has em cheap. C6 owners sell stock sets left and right, etc.

 

the PTE's are the best bang for the buck, they are cost effective and proven. why spend double the money?

 

Bump for facing the same situation.... sell my 950cc PTE's to get ID1000, or not really worth it? Does anyone know if ID1000 would have a better chance of passing state emissions?

 

I think the days of being scared to run bigger injector's are over. The response time of the injectors is so fast now, and it's so easy to tune the larger injectors that you're not sacrificing any driveability to run 1000's on a daily setup.

 

That may be the case. But I guess the question is even though they actuate faster than before, when the car is under load they will empty a fuel tank faster than a drunk in strip club.

I just find that regardless, if its much larger than needed, it isn't that necessary.

 

How do the guru's equate the older style injectors to the New ID-series injectors as far as cost/ necessisty, and does anyone have any insight into an emmisions perspective... IE: is it easier to get through emmissions by using the newer ID injectors (I assume this might be true).... Im bouncing back n forth between getting a new set of ID1000, versus keeping my PTE 950's

Thanks.

 

I dont understand how injectors could help you pass emissions, wouldn't that be in the tune, regardless of what injectors your using?

 

that aren't big enough for our uses unfortunately

 

The tune is definately a huge part of it. But its my understanding through reading that the old PTE style injectors are harder to control, and in a "sense" are on or off... The ID injectors are much more precise and easier to control.... Why do many people see better fuel ecnonomy once they switch to ID injectors... I just want to car to pass inspection, I know the PTE's will do the job I want them to do, just need the car to pass inspection so I can drive on the street. They are pretty expensive, so If I dont need them/ or wont get any more likelyhood of passing inspection, ill spend that money elsewhere.

 

the spray pattern is better on the new bosch stuff. you can see vids on FIC's website
