Default 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 have 98ron(similar to 93 US octane) fuel available. And my car is 1.6. IŽll try 8btdc timing. Thanks!

Whatch ebay, you can find deals sometimes on Bipes, and really good deals on a MSD box.

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!

I have about 35psi at idle.

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.
After pulling singal line out meter reads 80psi?!? I tried to adjust it but now needle is jumping between 40-70psi rapidly. ??? Signal line back and itŽs 35psi again.

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.
I got 6psi now so 80psi is ok? (Stock fuel pump.)
