since the other thread is full and 3 pages long starting a new thread.
ok, so i got the secondaries to get to 12-13 afr under boost. but it seems like it has done much. it doesnt pick up as fast for some reason. feels slower that my na 12a streetport. so far heres what i recorded.
-10.8 afr idle.
-10-12 afr cruising.
-12-14 afr secondaries opened up.
-timing is 5 degrees advanced.
-6psi fuel pressure.

 

put a msd box on that bad boy. your afr #'s look good , you could lean out the idle circut but the power will be the same

 

also, try posting in this section, im sure thay would be glad to help you out

hmm i pmed dan, but i got no response. guess there kind of busy.
ahh looking to get some msd boxes on there.
still deciding on whether to use 6a or 6al. also still deciding on what type of spark plugs to use.

 

the only difference on the boxes besides alot of money is the 6al has a rev limiter. so if your just trying to get your car running good then go with the 6a boxes. your stock coils will work fine. the new msd blaster coils are made in china now and there are alot of failures. the old ones were made in MEXICO, they worked great.
as far as spark plugs, you could use some b9eg, b9ev, b9egv nhk motorcycle plugs gapped down to .015 to keep the spark from going out. they are a cheap alternative to the mazda race plugs with the same results. you will have to grind down a spark plug socket to tighten the motorcycle plugs.

 

i have the older blaster 2 coils.
i think the spark plugs that are in the car are b8eg not to sure ill have to look it up when i get home today.
