Hey guys I need some timing recomendation on my boosted 13B 4port motor. Heres the deal. This motor uses 12A plates with GSL-SE rotors and complete rotating assy. I need to know what the stock timing marks are on the GSL-SE pulley as they differ from the 12A. IIRC its 2.5L and 12.5T. The reason I need to veryfy this is I will be timing the car using the tming guns advance dial as my pulley dont have the neccesary markings for say 20L and 10T. I already pulled the springs out of the dizzy so it will be at ful advance as soon as the motor is started.

Thanks, Ed

 

5*l 20*t

 

Okay thanks! Now I need to know what timing I should be running. I was thinking 10* L and 20* T for 10* split.

Thanks, Ed

 

Anyone running a boosted 4port?
