Currently I am running a 12:1 FMU with a inline fuel pump and stock injectors. How big of injectors can the stock ecu handle and what about the 12:1 fmu should I get a different disc?

Its recommended to use a 8:1 fmu disk with 310s. It should idle fine but if you want, you can always put in a SAFC.

 

I guess I should give you some background - I have a DRAG 3 kit, AEM fuel rail and S-AFC. So 310cc and 8:1 huh? ok

 

I've been doing the same research and your correct, go with an 8:1 FMU with 310's.

 

i'm going to be running the 8:1 with 370's and a SAFC, it should be running good however, i do know people who have run 310's with a 12:1 disk and been fine with idle, just slightly off, remember good tuning is key

 

So can I buy just the 8:1 disk...and what size injectors are in a Prelude? Can I swap OEM injectors from another car over besides the dsm-AFC-hack bullshit.

As soon as I do my automatic - manual swap I will be putting it on the dyno. I pretty much have unlimited use! free heheh

4th gen lude injectors are peak and hold so you need to use a resistor pack. The 5th gen are 270cc/min and those would work good as long as you have a OBD-2 car cause the clips are different.
I would recommend picking up a AFC or something either way just so you are sure your not going to throw any codes due to running to rich at low throttle due to the bigger injectors. You can try and lower your fuel pressure but it your idle goes under 32psi your injectors won't fire well enough to provide proper fuel at idle.
The FMU disc will change due to boost amount (need to look at A/F ratio on dyno) but I could run 11psi with a 12:1 disc on my 310s on a B16A2, but fuel pressure at WOT was 110psi.

I am OBD2 but plan to change over to OBD1 and the Hondata, so maybe I should just wait for that!
