Heres the problem, My plugs foul out or just don't work after a few hard runs. I'll put new plugs in and the first couple of runs are good, but go bad after that. I've tried all gaps with the same problem I can drive the car around town and on the highway no problem. It's when I take the car above 6k it starts to bang. I've checked the plugs and they look good. The list below is what I'm running along with the plugs I'm using! Any help would be great!!!

NGK R5672A-8 and NGK wires
JE 9:8.1 pistons
Eagle rods
Crower valve train
P+P head

XS eng intercooler
Crane ign and coil, msd cap

What heat level are those plugs. I'm using ngk bkr7e and they work fine so far. But then again i havent tuned in high boost yet...only got to 9psi cause turbo seals were blown.

 

is the power fc tuned? Could it be a bad map?

 

The heat range is 8, the power FC was tuned at Carboy in Houston. There a authorized power excel shop!

 

its your tune up...plain and simple

 

the problem is most likely your distributor. check the rotor brush and cap.I know it sounds far off but i had the same exact issue and that was the problem. I'm willing to bet 99% that is your issue. let me know.

 

I have a new type r rotor in my tool box. I'll switch it out tomorrow and see if it helps! Thanks everyone for all your input!!!

 

Changed the rotor, plugs and wires and still have the problem. I'm going to change the cap this week!

 

Change the cap and I bet it will fix it. I was experiencing the same exact issue and seemed like a long shot but it worked immediately.

 

do you drive a blue integra?
