I have a 94 rx7, and I am about to do a computer upgrade, and i think the best way to go would be the plug and play, but I want to know what you guys think. I also would like to know how much nitrous, if any, I can put on a stock motor. Also do I have to do a new radiator before I do a front mount, because that is what I've heard.

 

If you want plug and play, get the Apex Power FC, however you can try the AEM EMS, but it hasn't been tested much on the FDs yet. Rotaries generally do not like nitrous, but if you do shoot, I recommend a small shot, like 40. You do not need a new radiator before you put on a FMIC. However it's a good idea to upgrade the radiator on the FD before it causes future problems.

 

I have the PFC and the commander. I think that it is a great upgrade. Like legendr35 said the AEM EMS just came out a while ago and it looks like a lot of people like it.

 

Power FC is good for people that are new to the game and get some real upgrades before the N20. Pretty much do all the bolt ons you can.
