agreed, throw a MSD 6A amp in there and run with it.



(I installed one on an FD over the weekend and tuned it up to 19psi, not a problem...even ordered one for my car)

I agree with you guys. If I was starting from scratch I'd use a different box. However, since I am also working on (more like waiting for other people to work on) a 20b project car I'm trying to avoid buying anything for the 2 rotor that I can't transfer onto the 20b. With that said, I got an email from Justin today stating that the new AEM boxes should be ready to ship out in about 1 week.

Big news -I'm finally at 15+ psi I replaced the 9s with 10+ motorcycle plugs and it completely solved my high rpm stumbling problem. Whereas before it was stumbling at anything richer than 11.8 above 12 psi it now runs smoothly at an honest 15.2psi with afrs of 11.3-5. I was planning on trying to lower the afr to 11 flat, but my laptop ac/dc cigarette adaptor caught on fire (without the laptop plugged in) and promptly brought a halt to my tuning efforts. Hopefully I will get to the bottom of the problem and have it back up and running later this week.



In the meantime I'm having a blast driving the car. The acceleration in lower gears is awe inspiring. It will easily break traction in 1st, 2nd (as early as 4000rpms), and I even got wheel spin at 5500rpms in 3rd getting on the expressway today. In 4th the acceleration is still strong enough to lock up the seatbelts.



The best part about this setup is that the low end is still very respectable. Positive 'usable' boost starts around 3,000rpms and at 3600 the response is immediate and it pulls like a bat out of hell. A friend of mine had a ported motor with a 35R BB. His setup and mine feel indistinguishable from the seat of my pants. Considering the extra cost and questionable reliability of ball bearing center sections I'm glad I passed on that option.



After I get all my receipts in order I will document and post the package as a 'virtual kit' of sorts -a list of part numbers, prices, and contacts to duplicate the kit. Overall, I'm very happy with how this project turned out.

Any dyno time comming?
