Not sure if serious, are people with stock coils really gapping down that far?

Ive been going down to 0.6 and then upgrading ignitions around 16psi where it seems to get blowout with those gaps.

Thanks,
Dann

0.6mm should do it. Maybe sixshooter meant 30/1000 inch? That would be .076mm

Its a typo he means .030in obviously

Spark blowout usually happens around 14psi on stock ignition system. Degrades slightly as plug wires age, but not much.

This. Auto correct is changing numbers around on me constantly. Very frustrating.

I'm running .028 with mine.

Well i changed out the fuel pump for a DeatschWerks DW200. Took it for a drive and all seems well.

Interesting. My stock '99 fuel pump delivered sufficient fuel to blow up an engine (~250hp) at 14psi. Something must have been wrong with your stock pump....

I would have to agree.

My stock pump wouldn't flow enough for 12psi on the 2870 turbo.

What year is that? I _believe_ the NB pumps have higher flow.

Mine is a '96.

NBs have no pressure compensation in the fuel system for forced induction referencing. Not a big deal unless your boost is set high.
