Please can anyone tell me what the ignition timing is on my auto N/A (ie deg. BTDC etc) and also the idle speed. Just setting up after a rebuild.

 

Many thanks

Sorry hit wrong button before posting

 

Charlie,

Straight from the workshop manual;

Timing 10 Deg before TDC at idle speed.

 

Tick-over for 2JZ-GE 700RPM +-50RPM

2JZ-GTE 650RPM +- 50RPM

 

Usually at start up of the car from cold it will rev to about 1800 RPM then drop progressively down to normal as above, in a very short period.

 

Dont quote me but I THINK the timing is pre-set, may be others can comment on whether(or not) it is adjustable and how to do it.

George
