Thread: L32,L26,L67,L36 Diffrences?

Cool. So i'm going to be using a N/A intake. So what intake's are compatable. Since I am going to be using a N/A intake then that means it will have injector basses in the lim. I will be using Ported L67 heads wich also have injector bosses in them.


Wich do I use? The ones in the head or in the LIM? How would I go about plugging the ones i am not using??


Can I use a L67 lim with a N/A upper intake manifold? That would be ideal in my case.


Thanks for any help with this.

What are you talking about? lol I was talking about the injector holes.


And Yeah I already bought some heads with bigger valves...So that def not an option.

Yeah I probably would just use the ones in the head.

If I was planning a turbo build, I'd go L32 (first option) or L67 (second).

Might as well do an aluminum L26 UIM:

IMO the closer to the cylinder you inject the fuel, the better. But to plug the unused injector holes:





A friend made those for me. I'm sure I could get him to make more. With these, you could keep the holes around and, as was suggested, consider some kind of alky injectors later.

I would keep the n/a LIM, so you still have some runner length and don't lose all your low-end torque.
