Injector Size
 

I am piecing together bits for my setup and want some opinions on injector size. I have a na6 with MSPNP, will be using a fairly small t25 from a R34 GTR, and am hoping to make in the low 200rwhp bracket with around 12psi.

I already have a set of rx7 440s(199500-2010) which I have had cleaned and tested but not yet installed. I origionally went the 440s as I wanted to retain better resolution down low.

I have done the calcs and it looks like they should be around the right size for my expectations but I wanted to hear from some of you about it, as I don't know how accurately the figures apply in real life.

I do also have cams and am seeing over 90% dc out of the stock 230s N/A so this has me thinking maybe I should go for some 550s from the beginning to leave some headroom? Opinions?

Cheers, Tim

headroom never hurts but cheaper to use what you got if you already have 440's cleaned throw em in I think

Anyone else using the rx7 440s? Any more opinions to share?

I'm using a set of Bosch 465s, virtually the same as your 440s. I don't have a HP number, but on my intercooled, Greddy-based system (TD04H-15G turbo) running typically 12-13 PSI, the highest I've ever seen them go is ~80%. IOW, they seem to be ideally suited for this particular application.
