Yes yes I've already searched and found the rotary resurrection site with the injector sizes BUT... I was under the impression the 2nd gen Rx's use the 460's for primaries and a larger size for the secondaries. Are they both 460's? Does all 4 injectors fire after 3800 RPM to make 720cc per rotor then??

Thanks,

86-87 13B NA, low square center, 460cc, red, 195500-1350
86-87 13B Turbo, low square center, 550cc, tan, 195500-1370
88 13B NA, high square offset, 460cc, purple, 195500-1350

each injector is rated in cc PER injector

I already knew that stuff I was just wondering IF its DIFFERENT sized for the secondaries or just 2 MORE of the 460?

it is from the 2nd gen faq. its easy to overlook things in that faq. lots of good info in there!!

there are 4 460 injectors. 2 pri and 2 sec. Apparently that was to hard for the others to type.

thank you. Much appreciated. Next question...which is a better ECU for a 6sp N/A? N326 or N327? Can I use any AFM with either one?

nvrdone

6spd? Wat tranny? Yes the AFM will work with both. Not positive but I think the N327 is just an updated version of N326.
