1987 VW Golf GT 2.0l 16v ABA/9A w/ wasted spark now Turbo
Details:
Car
Originally an RD engine code 1.8l 8v CIS-E car
Engine
ABA 2.0l block, crank, and rods rebushed for 9A pistons.
9A Cylinder head w/ Autotech Sport Cams
9A oil pump and intermediate shaft, etc.
Head and block decked as necessary for flatness.
Compression should be around 9.2:1
ABF timing belt
7lb flywheel (oh what fun trying to keep it from stalling )
BBM fuel rail and dizzy block off
Adjustable 4 BAR FPR designed for Porsche 944 fit the BBM rail.
Accel EDIS style coilpack
Custom Magnecor 8.5mm EDIS - VW 16v plug wires

Accel EDIS style coilpack

Throttle body w/ TPS from Passat 16v automatic
I have about 1500 miles on it since I got the engine back in and MS running. No problems at all. I'm still tweaking the tables. I need to work on the warm up and afterstart enrichment. It idles at 900, and I got 26.5 MPG on the last tank, so I guess I'm not doing too bad.
Once I'm sure everything is right, I am going to strap on a T3 60 trim and start the tuning process over again.

Cam was 1 tooth off on the timing belt.
Lots more torque now!
No more miss. Idle is 900+/- 40 without closed loop iac.
Can't seem to get the 2 wire bosch iac to work right with closed loop. My pwm iac output seems to be inverted.
