I have my rom tune, cobra maf, and 72lbs injectors sold and I want to know what EMS and injectors to get for my holset HX35 top mount setup? I have a jgy top feed fuel rail and would like to get some top feed injectors that will support 600+whp. Can you use 96lbs msd's with a apexi power FC? What other EMS and top feed inj. combo would you suggest for my needs.

Ok, SR20's have high impedance injectors. A high impedance injector driver inside a ecu will not not last long driving low impedance injectors,(MSD 96lb-hr, 2ohm).Since the Power FC is a plug and play, it has a high impedance injector driver. I've heard that you can wire in a resistor of some sort to run low impedance injectors, but I would personally just buy a set of larger high impedance injectors. Also, since the Power FC is a plug and play, you will need to retain the maf.

If you want to be a baller and get every last hp, MoTec M400.

I used the AEM EMS with the GM 5 bar map sensor and IAT sensor on my old built DSM...Does that system not work well with the SR?? I have never gotten that far into an SR as of yet?? Just wondering

Yah, AEM would be a good choice. It will run low impedance injectors with a resistor box, and has speed density.
