Ignition advance & Fuel pressure with begi S1
What ignition advance (baseline) should I use with begi S1 kit. I have IC size#2, Begi AFPR and otherwise stock car. IŽll put 5psi boost. What kind of fuel pressures should I see with 5psi? IŽll get MSPN and more boost later this winter... Cheers!

Will depend on what OCTANE fuel you have available. I don't know what the conversions are, but if you have access to 93+, and you are IC'd, then you should be able to run 7* BTDC... perhaps as much as 8*, but listen closely for knock.
It's a 1.6, right... probably see about 70psi of fuel pressure for decent AFR's at 5psi boost.

I will get MSPN9093 later this winter, so I dont need MSD box. I just want to do quick testdrive and vehicle inspection with turbokit before I put my car for 4months wintersleep...
Coming up during winter:
ACT clutch, MSPN, Custom 2,5" Cat+exhaust, '99diff with Kaaz LSD. And boost UP!

If different, loosen the jam nut and adjust the center screw until the pressure is 47/49 psi.
Clockwise is more pressure.
Snug up the jam nut.
Plug the signal line back unto the FPR. The fuel pressure should return to the 28/30 psi figure.

it is more accurate to set the fuel pressure with the engine running under load.
Drive the car and while adding boost increments with the throttle, watch the gauges to match 8 psi
boost with 100 psi of fuel pressure.
