Best Engine Management for 98 16G built car

[FstAsVR4]

Thanks I appreciate all the help, now I'm leaning towards the ARC.

Edit: After doing some research it says that the arc can only support 720cc but I have 750cc, I also have Oohnoo's full fuel kit so should that help?

750cc injectors will work. Turn down the fuel pressure a little if you end up having problems. I'm not sure what the actual flow rate of the RC 750s are but on my flow test for the Denso 720s I had it showed that they flowed 690-700cc between them so that gives you a good baseline to work with. This was tested at base fuel pressure 43.5psi FYI.

750cc injectors are on the big side using a piggyback. You are going to get quite a bit of timing advance. Unless you are going E85, the 750s injectors could get you to 750awhp which is more than the 16gs can put out. Read Trevor's timing vs injectors thread on the other site. Pick appropriately sized injectors with the arc2. Or go AEM EMS and use whatever size injectors you want.
