Has anyone on here gone bigger with their fuel injectors. If so what did you use. I’m looking to upgrade my injectors. So any info would help.

Thanks.

What requires the upgrade? Forced induction? I think duty cycle will decide the size you need so you need some numbers to get something close to what is right.

I don't have larger injectors in my truck, it's stock. I have gone larger in cars and other vehicle's I have owned because of engine mods

I think holly might have a section in their tech area that talks about how to figure injector size

95% sure LS based injectors will work with top hats and adaptor harnesses. You can pickup a set of 56lb shorty LS ev6 injectors for less than 300, then all you need is a set of top hats to bring the overall length to 65mm.


You will need a tuner like Uprev/HP to set dead times, and play with fuel tables.

with good quality fuel injectors, you can go almost as big as you want.

I scoped out ebay for GTR injectors. Found 2 sets with each set missing some o rings or having a damaged injector and had a shop clean and match the best 8 out of them. They might be a little more up front than any of the domestic options but no need to spend on adapters and connectors.

Ps the brand new set of "GTR" injectors for $60 are not what I mean, those are terrible and should be avoided at all costs.
