Having converted to coilpacks i decided to completely remove the dizzy. Removing the dizzy meant moving the phase sensor to the cam cover Grp A style. The removal of the dizzy required an oil pump drive as well.

Firstly i made an oil pump drive by cutting the dizzy in half and machining the shaft to take a bearing



Then made a housing to fit in the block



Then pressed the two bits together




To give



And finally fitted to the engine



To fit the phase sensor in the cam cover you need to machine the cover to take the sensor holder




I then got the sensor, holder and phase sensor trigger. Available from Mountune or Zoo.





The sensor and holder fitted to cam cover



The cam requires machining to take the trigger



Thanks to Martin@Reyland for that bit of machining

The trigger then bolts into the end of the cam




Next update will be the timing of the phase sensor to the cam and final fitting of the cam and cover.

 

Excellent work .

If all posts were like this we'd all be learning more....

 

looking good, cant wait to do the same to mine.

 

Excellent post

 

very good ive always wanted a lathe

 

Has is been timed yet Rich??

 

 

Not yet mate, just waiting for the outcome of my oil pump fiasco before i re-time the engine back up with a new belt+tensioner.

 

Richie,

Did you machine the cover for the sensor, if so were the schematics supplied with the kit?

Also why did you give the cam to martin to machine? by all accounts you're more than skilled for the job?

Really going to be interested to how this is timed up!!

 

 

Tick tock tick tock tick tock!

 

Well i for one know this engines finished!


So finish the post slacker!!

 

I guess you've add the bolt on top to help the removal?

 

Will be taking some photos next weekend Jase when i remove the cam cover for powder coating



Yes mate

 

spot on richy

good work mate

 

come on rich you should have finished this by now

 

Hi B9 Kos,

Could you give me the dimensions of the silver bung (with the o ring around it).

I need to make one as I dont need the dizzy or the oil pump drive.

Cheers,

WD

 

Does anyone sell this complete kit of parts for doing this conversion ?

 

Just got my sensor and was wondering about the clearance it needs to run properly :

The cam extension lobes - fixed height.

The mounting flange - fixed thickness.

The rocker cover thickness - variable depending on refurbs etc

Should I put a washer between the sensor and mounting flange to put it back to 'approximatley' it's design height.

Cheers,

WD

 

According the GpA manual your are supposed to 'clean' the peint on the cam cover and fit shims between the houssing and the cover (not between the sensor and the housing) better if you have to change quickly the sensor between two stages but for us I guess it doesn't make a big differance as long as you have the correct gap

I'm waiting my new cams to machine the whole things to do the same

 

Does anyone know what the correct gap is ?

I had approx 0.5mm less gap then the length of sensor. I put a 1.00mm washer between the sensor and housing so I now have approx 0.5mm clearance.

Based on the crank sensor spec this is OK but is it also OK for the cam sensor ? I guess the cam sensor could cope with quite large clearances as the magnet in it is really stong (compared to the crank sensor) and the lobes it talks to are also bigger

 

the gap it needs to be set at 0.015" to 0.018" (0.38 -0.46mm) so you're a bit far but I guess it will work anyway

Looking to make one myself i am sure i can work out dimensions but what does the cap head screw do on the top. I assume the bearing is a press fit etc.

Many thanks

 

Would be a lot easier to use the jackshaft pulley than the cam itself for the phase.

.. For later'rs

 

to get the dimensions to make your own oil pump drive just pull your dizzy out & measure it .

the cap head screw is there purely as a means for getting the oil pump drive out again ,i.e. undo bolt grab with pliers & pull .



ps i know this is a old thread but it still needs more information to complete this conversion .


pps i do not need the info as i already done my car but i have been asked by pm but i can not remember it all .

 

This is helpful, but is there any other guides on this more uptodate?

got my cam cover cut,
need to machine the cam for the trigger.
cheers
Ken

 

Awesome mate cheers.
