So the motor is built and installed. It runs mint except it won't idle right at all.
Tech Specs:
B18A1 (90-93 LS block) Bored to 2.0L with new iron sleeves and JE 12:1 pistons. Eagle H beam rods, turned crank, and everything is balanced and printed. GSR head that's been ported polished w/ 5 angle valve grind. Using JG Race valves, GSR liters and rockers Type-R cams, Skunk2 intake manifold, and AEM cam gears. Running stock Type-R ignition, AEM fuel rail, Type-R injectors, AEM regulator, AEM cold air, Stock Type-R exhaust manifold with Apex-i N1 exhaust.

Outcome:
Cam timing is set to TDC. Ignition is set to roughly 15-18 degrees advanced. I've checked for vacuum leaks, and found none. Fuel pressure has been changed from 20 psi to 60 psi with no change. Timing was adjusted from 5 - 20 degrees advanced. no check engine lights, and the IAC is fine.
So, the way it sits right now I manually adjusted the idle to 1500 rpm, but it fluctuates and is rather eratic, and won't idle below 1200 RPM.

 

It may be due to your increased fuel pressure from stock. If you are still using the stock ECU prog with no other fuel controller, the computer may be having a hard time compensating to control the extra fuel through the injectors.

Just something id like to share ... my stock B18B intake manifold has a very very slight warp on the intake runner 1 side ... enough that it sucks a tiny bit of air around the gasket ... i was gonna double up on the gasket to fix ... but ordered a skunk2 intake manifold insted ...

but the way i finally figured it out .. was have a friend rev the motor just a tiny bit .. and i sprayed WD40 right near the Intake manifold gasket .. and it sucked the wd40 right up into it . .


good luck man
