If I cannot get hold of a MK1/MK2 dizzy what options do I have? Can I use a non-turbo variant or can anybody recommend an aftermarket alternative?

I ran a welded-up dizzy, set at 25 degrees for years. It's not an ideal set-up bu it works.

A fulll electronic ignition is what you want.

Or get any 1275 electonic dizzy, and post it up to RaceSpec (01925 636 959) and get him to modify it to 'turbo' specification...

Turbo dizzys seem to come up second hand quite regularly, keep an eye on ebay. I would guess you won't struggle too much to find one.

That sound's like the easiest/cheapest solution, thanks!

daft question: What's the difference between the two? It's not just a different curve is it?

Nothing ignition wise.

The only difference is that the Mk1 dizzy you can get a flat type dizzy cap for to make more room at the front of the engine for intercoolers/radiators/whatever.

It is often bandied about that the Mk1 dizzy has some sort of super-duper improved ignition curve, I cannot find any evidence to support this and have had both types in bits......

back on the electric metro dizzy's, can you advance them in the same way as a non electric bobweight dizzy?

The electric distributor only uses electrics to trigger the coil. The advance curve is still controlled as a conventional dizzy with bob weights, primary and secondary springs, and the vacuum advance unit.

you just need a stock 1275 electronic dizzy.

Before Racespec can mod one, they need some basic figures however...

You need to get on a RR with any old dizzy you have, and swing it around every 1000rpm increments to get the best power, then note the advance. You then send these figures to racespec and they'l make you a custom dizzy. I'm sure you'll find a company in Oz that can do it for you aswell - a dizzy is a dizzy afterall...

I have used 42635 dizzy's (ie the latest from cooper, british open, etc )with success, just play on the idle timing until you meet knock and then retard 2/4°, I generally found that 5/6° initial timing , is ok,depend on the boost and cr.
