Anyone know if leads that fit a 3.0 24valver (Opel Omega, you see) will also fit a 2.8 carb Royale engine? I'd guess at 'yes', as they're essentially the same engine. But just wondered...  ta 

[zirk]

Royal was a straight 6 wasn't it?

But if you mean HT leads, things to consider are lead length, probably no diss pack, guessing Distributor? so possibly resistive leads, or built in ballast?

[Diamond Black Geezer]

Aye, HTs, and yes, the straight 6, which was (basically, if not actually) the same engine/block from the 60s 2.8s, to the final Lotus and 3.0 / 4.0 irmsmcher engines. (yes I know there's a million differences, but we're talking broadly)


A 6cyl project may be occurring in the near future and I'm just sounding out what parts are available...

[Marks DTM Calib]

Don't see why not, the distributor and plugs were all in similar places

[Diamond Black Geezer]

I know Keith ABS will most likely know for sure, and he also sells a range of them, but that's one Mark vote, in the right direction, anyway.

But then if it was me, the first thing that would get upgraded is the ignition setup ! (on any prehistoric car I bought)

[Diamond Black Geezer]

That is a thought.. hmmm.. can of worms I appear to be opening here

Its by far the weakest thing on any older engine, have Megajolted a few cars from Rover V8 through to Type 1 air cooled, every one showed a night and day improvement (the air cooled yielded better starting, ran significantly cooler, throttle response much improved and far more economical)

Yes, the fuel savings on a V8 with Megajolt will soon pay for the installation, especially if the distributor needs replacing. The better hot starting is a real boon, and the ability to time ignition correctly allows real optimisation of multi-carburetor installations. The bigger and lazier the engine the better the results seem to be.

I used to think the same until we did the Beetle engine.....which had been fully rebuilt with new standard dizzy, coil etc.......and it transformed that asthmatic little lump to!

[Diamond Black Geezer]

Just looked them up, fair few quid, but everything's relative, I suppose, and that includes the lot, inc leads, loom etc. If it's tweaked from 20mpg to 30mpg, that will pay for itself relatively soon. Hmmm... more food for thought...

Beetle engines are like the A-series: they're so badly designed that even a small change usually makes a worthwhile improvement.

The 'hard' part is fitting a trigger wheel to the crank pulley, but really it's a simple lathe job. Then you'll need an Edis 6 ECU, crank sensor, wiring and coil pack, which come up on Ebay, or you might be able to find a V6 Mondeo or Jag to rob it from.


With a little scrounging you'll do it for less than £250, much less if you're lucky.


I might still have a Megajolt ECU and loom somewhere that would be cheap.

Very much watch this space, then boys. Will let you know what pans out. As ever, thanks Nick and Mark.
