Thread: 93 distributor ??

That thing ontop of the DiZZY cap is only an aid to pull the lead out without ripping the crimp off. Its non-standard fitting and is more bling than anything else.
You need to read Beeuteys write up on what would be a true "Bosch" upgrade.It aint the leads or plugs or Cap , its the AMP that needs upgrading .The amp could be mounted on the side of the Dizzy,or next to the radiator or next to the airbox If your 93 is a serpertine job(you never can tell whats in what model !!) then the 85 dizzy will have to have the wobble drive removed.
Never forget to set the air-gap as Beeutey has detailed.

It's an RF suppressor.
AFAIR 92 or so is when stringent RF noise regs came in in the USA.

And you are only supposed to use suppressed plugs etc.

Purpose is to ensure as little noise on radios as possible in traffic.

The insulator thingy goes in the bin whenever I see one as its rubber skirt is usually split/perished from the heat. Fit a modern set of inductive core leads and you don't need it, regardless of whether it is a suppressor or not.

If you unscrew the Lucas amp off the '93 dissy you expose two female terminals that are 3mm wide. Your adaptor cable can be made using two 6.3mm flat crimp terminals and carefully cut them in half. Pic from the Bosch conversion thread:



Dead easy.

Have fitted top gun spiral wound racing leads and bosch wr7dc+ plugs (they were all preset at .7mm) and set the timing at 10 btdc, was about 2 btdc.

Daughter had a meet with her brother in Brisbane so will fit the amp on her return.

Was just being slack by fitting the 85 unit, easier option with the longer wiring, but on reflection I think a new set of wires maybe a better option, the existing coil is a bosch unit, not sure of the part #.

Had a little difficulty getting the 10mm air gap between leads on the near side due to the gas fitting clutter, considering fitting small plastic tubing between the leads and fixing with cable ties, also where they come in contact with metal??

Thanks for the pic, will post pics of the completed project.

Cheers jhonno

I often use 10mm split corrugated tubing around plug leads to keep them apart a little, narva part number 56710. The 10mm air gap isn't exact science, but the more length that leads are close to each other the greater chance of interference.

Metal (engine) contact by a lead is no big deal, what matters is the magnetic effect between a lead that's firing and the next one coming up on compression.
