porksoda Posted August 29, 2012 Report Share Posted August 29, 2012 After doing some reading I decided it would probably be best to upgrade my injectors for my next round of mods. Bought the truck mostly modified from previous owner and it was tuned by Zippy so I have no numbers on the injector duty cycle. I am merely guessing I need bigger injectors based on all the searching I did and people almost maxing out stock injectors with bolt ons and a tune. I am looking for injectors that will work with a TBSS intake manifold and TBSS fuel rail as that is the next thing I will be throwing on along with a 3200 stall. I wast to get this all done and have Texas Speed and Performance do the tune as they are local to me and can run some live data logs and get the tune down with all the new stuff. From what I have read the 8.1 truck injectors might be enough but that may be pushing it. Then I was looking at the SVO red tops but don't know what mods I need for them to work with my setup. Then there is the 8.1 marines but wow they are plain expensive! current mods-Walbro 255LPH Comp Cams 218/224 562/567-114 ZO6 yellow springs 7.4 hardened push rods zippytune 160 tstat Pacesetter LT's 3" Spintech true dual exhaust Transgo HD-2 Shift kit corvette servo 05 efans Volant CAI Quote Link to comment Share on other sites More sharing options...
silverado777 Posted August 29, 2012 Report Share Posted August 29, 2012 I know a lot of people use the siemens deka 60lb injectors. Zippy recommends those a lot as well. Quote Link to comment Share on other sites More sharing options...
The_aSSet Posted August 29, 2012 Report Share Posted August 29, 2012 You should be fine with 8.1 marines but if you ever plan on going bigger then might as well get Siemens deka 60# Quote Link to comment Share on other sites More sharing options...
porksoda Posted August 29, 2012 Author Report Share Posted August 29, 2012 My only problem is them being like $400. Really can't afford them right now. I'd much rather find some for my setup now because it will be years till I throw a radix or something on. Quote Link to comment Share on other sites More sharing options...
The_aSSet Posted August 29, 2012 Report Share Posted August 29, 2012 Buy used. I got mine for 275 I think. New but never used. Check pt.net Quote Link to comment Share on other sites More sharing options...
JC03SS Posted August 29, 2012 Report Share Posted August 29, 2012 I have almost the same exact setup going on in about 2 weeks and I'm going with the marines. I'm sure it will be the right ones. I'm getting mine new tho from gm I don't want any probs. Quote Link to comment Share on other sites More sharing options...
porksoda Posted August 30, 2012 Author Report Share Posted August 30, 2012 What about the flex fuel injectors? Will they work in the rail and intake as long as I get the harness for EV6 to mulltech? Quote Link to comment Share on other sites More sharing options...
Fireman31 Posted September 1, 2012 Report Share Posted September 1, 2012 See if you can find a set of 42# Delphi Multec II injectors out of a Magnacharger Radix kit, that is more then you need for your current setup, and they are plug and play, no splicing wires. You just need to update your tune for them.... Quote Link to comment Share on other sites More sharing options...
