okay so know that i think i have the right information according to the FAQ section,
(86-87 13B NA, low square center, 460cc, red, 195500-1350
86-87 13B Turbo, low square center, 550cc, tan, 195500-1370),
I can use the turbo injectors in my n/a car cause they are both low impedance with square centers...right?
I just really need a lot of help with this.
thanks again guys,

No, the turbo injectors will supply too much fuel.

That would be enough injector capacity for about 300hp and 550hp respectively. Are you actually doing anything to the engine to warrant that much fuel like a race-only PP engine or a huge turbo?

Unless you're planning to exceed 250hp, keep it stock.

thanks again guys,

The turbo injectors, and any injector over 460cc for that matter, are overkill. The stock 460cc's are good for 230hp+. If you make that on your N/A, let me know how
