zetec timing
forrest - 2/2/08 at 05:22 PM

I am in the final stages of my build, using a early 2.0 zetec with 45 webbers , with a T5 gearbox. ( to be changed to a cossie at a later stage ) In order to make all this fit together, the zezec flywheel was swaped for a 2wd cossie flywheel. ( this involved welding up the 9 hole PCD on the cossie flywheel and drilling out to the 6 hole PCD of the zetec ) This was only done because the starter motor will not mesh with a zetec flywheel in a t5 box.
having now done all this, i have lost the use of the CPS on the back of the flywheel, so i was going to fit a trigger wheel and sensor on the front pully.
Has any one done this, will it work ok ???????????

I've put a cvh trigger wheel on my blacktop crank pulley.

Yet to see if it works, but can't see why it won't.

I'd be worried about the welded flywheel!

Get a new steel one made if you must, and keep your legs in one piece.

Cheers,

My thought exactly. Welded up the holes and drilled new ones???? Are you mad? Can't be strong anymore around the centre of it.
How did you make sure the new holes are perfectly on the diameter needed? Have you balanced the flywheel, if not don't use it!!!
I'll dig some pictures up on flywheels gone mad.

Found it, look here

Hi if it's not a silly question why do you have the need to use a cossie box. I cant see you getting enough power to need such an over engineered gearbox for the application.

My thoughts also, is it not possible to make the starter fit by modifying it or the mountings.A welded cast flywheel is not going to be safe.

As big_wasa said, I did just that and it worked perfectly. I had some long debates about whether the rubber mounting of the front pulley would affect the timing at high revs so we machined it so that the wheel located to the central part of the pulley not the rubber mounted outer bit.

I was using an Emerald ECU so I could easily set this all up. I'm not sure how you'd get away with it trying to use the standard ECU if that's what you're doing.

I did it because I was using a CVH flywheel which can be lightened more than the Zetec one.

If I go Zetec again (still undecided) I'll do the same again!

I won't comment on your choice of flywheel as there's enough advice above!

Welding up holes in a flywheel is very risky, all sorts of potential reasons for it to fail.
