Following on from my previous thread - which has had all of the photos removed (thanks photobucket!)

A brief history:

I acquired the car approx a year ago. A bog standard looking mercedes W124. It housed a 3.0 OM606 turbodiesel, coupled with a large borgwarner S300 turbo, and a very mean 8mm dieselmeken fuel pump. The drivetrain was a 6 speed swapped from an E270 CDI, with a custom clutch and flywheel.

The car on this set up ran 562whp. It kept disintegrating prop doughnuts. So i sent it back for the large(st) diff with quaife internals, and heavy duty shafts. This made the car very scary in second gear, as it seemed to put down the power and access it alot easier.

I had such fun giving phenominally powerful / expensive motors a shock. Soon it developed a knock and without warning shot a rod at cruising speed.

I had a new engine fitted and took it off the road for winter. She was wastegated at 300whp on the dot, (362bhp) i personally thought it was more, but i guess its the delivery of the large turbo... nothing... nothing... 'oh god my face!'

I debated selling, and even advertised her for sale. Few bites but nothing major. Secretly i didnt want to let her go. There is just something addictive about a superturbodiesel. The old school diesel knock and rattles - yet the butter smooth revving throughout the range. These engines love to rev, and sound phenominal! Every one loves a big turbo spool!

I sent her off to my brothers business. She had the full AMG gen 1 kit (including ducktail) fitted and almost a full respray. 18'' geniune staggered monoblock wheels and the windows moderately tinted.

She currently stands as so:











Theres going to be quite a few updates in the close future - suspension, maintenance, a few more body tweeks and the one im most looking foward too - the priority valve (quickspool) manifold to help spool that big turbo up! I will also have a pump tweek and dyno at the same time. Maybe not as much as the test car ran (611whp) though! As i want to keep this engine...

That's truly amazing, is that on stock internals or forged?

What's the mpg like on a cruise with a great big turbo?

What type of dyno was it measured on? Would be interesting to see what it makes on a Maha dyno (proves to consistently be the most accurate).

Also very interested to see what quarter mile this would run and 100-200 km/h time.

Top work!

That's cool. How long does it take to spool up?

I love that. Is it on the DieselpumpUK Youtube page? I've seen a few of his creations and they just make me laugh every time. I'd love one.

That looks brilliant. I would imagine such power in a w124 (I own 2) is scary!

More please. Whatever you have.

Unopened engine. They are forged crank as sta ndard. Believe its from an AMG of that period.

I achieve about 32mpg on my last 200 mile round trip. That was sat at mainly 80-90 mph will some wot. Ill do some vids after i get the manifold. Currently 1st and 2nd is pants!

That rear wheel looks like its been photoshopped in from a slightly different angled photo, looks like its got positive camber ?

Have you timed any performance figures yet ?

How would it go against say a standard C63 ?

Looks mean, LOL at that current rear ride height though!

Was this near Otford/ Sevenoaks last week, I saw a white merc like this, the one I saw could have been lower though.

No it hasnt been photoshopped lol. It had just come off the ramp so hasnt settled at all in that pic. The fronts dropped a fair few cm after a day.

I havent done performance figures for the simple reason that 1st and 2nd gear were usless. Wouldnt spool till 3rd. Ill get a vbox after its manifold and do some tests.

No idea but at 300whp its slightly quicker than a V8 M3. Ive had a play with 2 locally and creep on them both.

When it was 562whp there was not nothing that touched it.

Just go her back from the first installment!

New engine and diff mounts. Diff ones were well worn:



Also had fresh diff and gearbox oil.

The SL500 springs have had a coil lopped off the rear. I was hoping to get my shocks on too but they have been put back until the end of october due to availability. Gone for Bilstein B8.

How she sits currently

Had a chance to use my new cleaning stuff today. Always been a fan of G Techniq since i used there glass protection on an A8 years ago. Amazing technology.

The nano polish took the stained soot of the rear easily. And the crystal lacquer is very unusual! A spray that you simply spray, then wipe. But evidently will last 4 to 8 months as a wax. So easy to apply - and just after id done the rear it started spitting:



Beading well. Ill see how long it lasts.

Also fitted my fog lights. Purely cosmetic until i wire them in at some point.

Had a test of the snowfoam today. Its interesting to watch the colour turn as it pulls the dirt off!





The windows have had the g techniq glass treatment, and the majority of the body has had crystal lacquer applied. I absolutely love g techniq products. The science behind them is fabulous!

Also peeved off a civic driver today, thats always a bonus!

I just don’t know how you can resist the temptation to have a wee twiddle with the wastegate, you must have the restraint of a saint.
