I'm at the end of my project & I'm curious what gap I should run on my spark plugs. It's a 1998 Mitsubishi Eclipse Spyder GS 5 speed here's the list of what I did:
16g turbo
Tubular exhaust manifold
2g O2 housing
2.5" downpipe & cat back exhaust
2g MAF
J-pipe & 2.5" hard intercooler pipes
FMIC
Greddy bov
450cc injectors w/ resistor pack
1997 GST ECU
Rewired fuel pump
Installed knock sensor

I only plan on running 10-14 psi, I've got ngk bkr6es-11 plugs. What should I gap them at?
 
As I understand it you want to run as wide a gap as your ignition system will reliably fire across.

I'd start out at the same gap the factory spec'ed for the 2G Turbo cars of 0.028 to 0.030in and work from there. If you're misfiring try tightening it up.
