Just wondering which of the two spark plugs on cylinder one you connect the timming lighjt two, and what degrees should it be time too.

Either plug is fine as they fire at the same time on the stock ECU. Timing is 12BTDC. Disconnect the vacuum hose as usual when checking the timing.

yes... cause even at idle there is pressure being fed to the advance, although minor it does make a degree deifference and depending how you want to set it up in respect to how much advace you want and when you want it makes all the difference

Yep, theres one pin and 2 cut outs on the pulley. Line one pin with 1 cut out to get TDC and the other one is the mark for 12 BTDC.

OOOPS sorry mate your right! i said it the wrong way... one pin and 2 cuts so as TA22 GT said... you will find that the left cut is TDC and the right one is 12BTDC

Fadee,
BTW, the dizzy sequence is for a 3T GTE using a stock ECU. Aftermarket could get fancy and fire each plug individually.
Either way it will be 1342. If there are offset it would only be slightly, so it would still be 11 33 44 22.
the idea of twin plugs is to gain reliability and to ensure all fuel is burnt. Not real sure if it makes alot of difference as most engines are single spark and work fine.
Cheers,
Simon

Yeh i understood it as being a way to beat amision standards it helps burn it of alot better, the difference in performance is niel or next to nothing,
So two cut outs and one pin how do i know which cut out is 12dtdc.???
Also unsrue of wha it is but the car will run like shit after a fair workout (foot to the floor alot) and is quite hard to start, it has an ems computer, wondering if it could be plugs or injectors.

Sorry about my grammar was in a hurry

yes when you face the pulley from the front of the car the one on the left is TDC and the one on the right 12deg BTDC.
As for the twin spark making no difference to performance? I would not be too quick to jump to that conclusion - the more efficient that the burn is the more torque you stand to gain - small amounts sure but non-existent? definitely not.
The way the leads are arranged is not 11 33 44 22 (although that is the firing order) they have small pads on the distributor cap next to the posts teling you whether they are 1F (1 front) or 1R (rear) etc. It goes something like 1F, 3R, 4F etc. Also to make it dead easy the factory leads are labelled too as are all of the wire dividers (to get the factory neat "no wires touching" layout).

ok i timed it this morning it was only about 1 to 2 mm from 12btdc, ill have to wait till tommorrow to see what sorta start it does, another question im thinking of changing spark plugs as it about to get tuned and i dont know how long they have been there for what would you guys go for. ???

as for poor power after "foot-to-floor" - the air temp from turbo will increase so the computer will increase the fuel and u'll prob notice black smoke from exhaust. hot air is the main cause for lack of power
