hey everyone.. we are looking for opinions on what brand of injecters people are having good luck with in boosted L98's. we need some in the 42lb size.. i'm helping a freind piece together a single turbo set up on his 1986 L98, we have most of the setup on and ready but now we are getting to the fueling upgrades part, opinions greatly appreciated
Thanks!!

Hi
Bosch design 3
Have fitted them to my blown c4 smoother idle, harder acceleration and faster than the original injectors
You cannot go wrong with them.
Depending on the boost you are running that will determine lbs size
i am running 8psi vortech blower, intercooled and using the 30lb with a fuel management unit to restrict fuel return to tank raising psi and forcing more fuel thru injectors.

For more boost or stroked you may need 30lb? 40lb seems a bit much?

I've used Lucas 42.5 lb/hr injectors and Siemens/Continental Deka 63 lb injectors. Good results with both. Different tuning including offsets, of course.

Used to run the Siemens 83 lb/hr, but put the Lucas 120s in there a few years back. I have used a lot more sets of Siemens than any others, and very satisfied.

Eithers brand will do fine.

For the lower flow varieties, I like the Ford injectors.

Hi Guys !!!
Number 1 is to order "Flow Matched" to 1 %. This assures you the injector actually works and just as important flows what it is supposed to !!!!!!!!
Number 2 is not to buy more injector than you actually need because like a laser aimed at the moon you just make your job more difficult. It's not that a bigger injector than you need is necessarily wrong but when you get into the constants and offsets etc. you need to be more precise. A smaller injector is more forgiving of errors !!!!!!
