Ok so I have a few questions about the fast mani setup I'm looking to do. I know its kind of a intake question too but the injectors is what has me puzzled
1.will I need to get the fast fuel rails if I'm getting fast 60 lb injectors?
2. will 60 lb injectors work with e85 I'm looking to start using corn.
3.what should I do about the MAF sensor I need a bigger MAF correct what works well with them?

1. No you shouldn't use fast injectors.
2. It depends on the setup, but don't use fast injectors regardless.
3. Maybe, it depends on the setup. Don't use fast injectors.

Which Fast intake are you going with?

Are the fast injectors not a good injector? what would you recommend?

freaky57fast

the 102 with the 102 big mouth tb would a 100 MAF work well with them?

Fast injectors are re-labled injectors from who knows where. There isn't any reliable characterization data for them. While WOT will work ok, you'll have starting and drivablity issues. What's the rest of your setup?

My fast 102 setup is stock ls3 fuel rail, stock ls1 injectors resized and flow matched by fic, cbm fuel rail spacer kit with new orings, fast throttle body which ive always had on off idle problems with.

What kind of off idle problem? What makes you think it's attributed to the throttle body?

Its in my Sig I'm running 98-100 duty on my stock injectors.

Tuner messed with the iac counts on and off for awhile, it would randomly die on the freeway which wasn't fun or coming to a stop as soon as I'd let off because it needed air. I just cranked the blade slightly open and reset the tps and left it alone instead of drilling a hole in the blade. Now it'll run just surges every once in awhile aka cruise control lol. I hadn't taken it back to my tuner and not too bothered by it since I barely drove it, if the idle hung coming to a stop Id just slip the clutch a little and itd go back to rowdy town. Plus side is my fuel pump died and I'm gathering parts for my head swap so hopefully he can get it dialed in when it's redone.

Eagle if you have any ideas let me know man, I ain't no tuner but can relay whatever it is for him to check out before I swap it for a nick willams

Sorry I don't see signatures because I'm on my phone most of the time. You'd be fine with ls3 injectors.


I'm not a big fan of the fast TB. I like the Nick Williams. Without looking at your tune there are too many things it could be to guess. I would suggest that since you have a 00 you upgrade to an 02 OS.

If you wanted a little bit more insurance you could go with gm 50lb/hr.

I was looking at 60lb injectors resized from my stock ones. I was just confused about the rails id need with my stock injectors it said ls2 but also said something about fast fuel rails on the site I was buying the intake from... so ls2/3 fuel rails and spacers for it? I might just order the intake first to fiddle with first too. the shopping carts kinda full and my wallet isn't ATM lol

42lb green tops work well with my fast 92 / nick williams 92 tb.

http://calibratedsuccess.com/media/technical-articles/ Read the article "Who's getting drilled"
It'll help you understand why I highly dislike resized injectors.

If you want 60lb injectors buy some SD60s. You want something with good injector data available. Ls3 injectors cam be found cheap. So can the 50s I was talking about.

freaky57fast

alright ill read the article thanks for the help. ill look into ls3 or sd60s do they fit just like an ls1 injector?

freaky57fast

are those the green giants?

eaglegoat

The ls3 and the SD60s are shorter than the ls1 injectors. You would need a top spacer kit. No big deal. FIC sells a nice one.

i'm not running the green giants, no. these are just delphi 42lb'ers.
