Josh, with the DIS-2 did you have to run a MSD 8912 DUAL CHANNEL IGNITION ADAPTER for the ECU? Or just wire it into the two coils wires and go?

I just wired it up to the coils after the ignitor. It was a pretty simple installation. I have been very happy with that purchase over the years.

I read a little bit on NGK's website and they supported/recommended these ignitions that increase spark energy. Like I said, I was running 19 - 20 psi and never had any hesitation issues, and based upon the feedback here, I attribute that to the Dis-2 ignition.

What subaru do you have that is only 2,400 lbs and has 425 HP?

I was running my 2.3 Mustang at 425 HP. It lived for 2 years before puking its guts all over the road. My build was mild compaired to this one:

Hmm, I'm going to keep the 0.35 gap in mind when i replace my plugs...

Do you have any problems in boost CJ? How much boost are you running?

right now im running 9 lbs... I'm having a problem boosting above that, but it's not spark or fuel cut related. One of my intercooler pipes are bent up at the end pretty bad so anything above 14 and boost leaks out of the coupler and the car stumbles... i have yet to fix it cuz i need to get some more stuff for my welder.

I just wanted me make a mental note because im doing my plugs soon and a lower gap seems like it'd be somewhat beneficial.

You have any o2 sensors laying around that are good? i cant find one out here at all. Jake has a new one but i don't have 100 bucks.

cj91legss, I just bought a Bosch 3 wire universal O2 sensor for $59 at Orileys. Part number 15726.

If you get one, you will need to cut the three wires off the old O2 sensor as close to the sensor as posable. The OEM sensor has a RED, BLACK and WHITE wires. The new one has 2 whites and one black.

This is where it gets funky but follow me if you can.

Wire the old WHITE to the new BLACK and then the the old RED and BLACK to the 2 new WHITES.

I could email a picture if needed.

That was plenty understandable, only problem is i don't have cash for that right now... CEL everytime i am at a stop light and bad idle... And it doesnt like to pull good at all right now.

I think I have the o2 from my jdm forester downpipe but not sure and don't know if it works. Its yours if you want it and if I can find it.

awesome!!!

However...mike might have taken it already. I'll have to look next time I go over to my moms.
