Thread: Got another old W123 Merc today - this time a 300D.

Is d-gassing a non-turbo a reasonable/economic proposition? Or do you need the turbo to make it worthwhile?

Are there power gains on a normally aspirated diesel, or would you do it to get better overall MPG? Sorry if these are basic questions - have not researched d-gas much at all.

Thanks
David

Diesel W123 Mercs are the best things ever. My brother's driving a 240D, which has been in the family for thirty years. It succeeded Dad's VC Valiant, which was a legend in its own right, and has just kept on keeping on....

NA diesels I convert need limit switches at both ends of the throttle travel. The high end one cuts gas so overfuelling and black smoke are reduced. In between realistic but slight power gains are to be had, and of course running costs will go down.

Oh and the LPG rebate still applies, so its a low net-cost operation.

Mercs were/are safe cars in their time. They had crumple zone technology back in the early 1960's.

Looks good. Keep you fingers crossed. Old used car trade proverb: There is nothing as ezpensive as a cheap Mercedes.

I think from memory, we share the same Merc mechanic in Norwood, he be able to tell you what turbo if any were suitable.

These cars often clock 1million K's in Africa and Greece, I see no reason why they can't do that here.

Good luck with the Panzer Wagon

What was the year range for these W123 models?
How much would a decent W123 merc wagon cost?
I gather the petrols are pretty bad on fuel ?

I see the W124's can be had for under $10K - are they any good? Seems they at least have leccy windows.

Yeah - Barrie Green, just off Magill Rd. He is great but must be about ready to retire unfortunately.

He checked out an earlier (much rougher one) I was looking at, but he hasn't looked at this one yet. Will be booking it in to him next week to get a few things attended to.
