Hi all, back after two house moves, covid and a general lack of time. Now motivated to get the project moving again!

Walked into the garage at the new place and see a sad looking dusty mess sitting there on stands and decided a quick freshen up wouldn't cut the mustard. So... much to the annoyance of the wife (locost widow) I made a start...

• Stripped the whole thing down to the chassis and finished all the little bits of welding I was putting off

• cut out the steel floor and replaced with 2mm aluminium

• ditched all of the old interior pannels and replaced with aluminium composite board type stuff

• Completely remade the loom and made it modular so I can remove complete sub looms in one go using aircraft style fittings

• ordered carbon seats and harnesses

• got a pair of rally design front uprights, willwoods all round, new steering rack, bearings, bushes, ball joints ect ect

• started to wire my dash dials

• run fuel/brake lines and clipped in place

• made a battery shelf/holder up to sit above the diff and fitted a pc680 battery

• have started making my rear wishbones to take the mercedes frankenstein hubs

• fuel pump and fitler plumbed in

• pedal box half squeezed into final position and 3 chamber fluid reservoir fitted

Will update some pics later tonight or tomorrow when I get a quiet half hour at work

.... she will be tested this year....

If you wrap the img urls in [img ][/img ] tags (without the space) and remove anything after .jpg it should work like the above image

Looking good by the way! And great choice of speedo - I fitted the very same one to my MK last year.

Not 100% sure without seeing... But it looks like you removed too much of the url. It needs to have the extension on the end - .jpg or .png etc.

But yeah, make sure you have the [img.] tag (without the dot) before the url and [/img.] afterwards (again without the dot)

Oh screw it, done with this photobucket rubbish just to upload a few progress photos

Pair of carbon bucket seats fitted, now just need to work out the harness mounts

New aluminium inlet started with velocity stacks and a larger throttle body

New aluminium supercharger manifold started (just needs welding)

Sump shortened by 50mm and baffled. Pick up dipstick shortened accordingly

Engine all painted up and prepped

Rear uprights finished and bearings installed (slk merc)

New gaskets/seals on engine

Sorted the "lifetime" seal on the gearbox that is not available (42mm freeze plug hammered into the hole)

And have saved nearly 50kgs in the past couple of months with more to come

Bit of a progress update (no photos as I'm sick of arguing with PB).

Plug mould for the body tub is nearly complete, just the bonnet and front wings/pannels left to do.
Suspension and rear wishbones are now all finished.
Rear brake caliper carriers completed.
Handbrake mechanism completed.
Coolant system complete and leak free so far.
Revised inlet manifold is with the welder, more than 3kgs lighter than the steel one.
Tweaked steering column done, 0.7kg lighter than the last attempt.
Revised supercharger top hat with welder, less than 1kg all in.
Revised bypass valve sorted, just waiting on the postman.
Fuel rail/injector bungs fitted with larger injectors.
Cut down sump fitted along with modified pick up, all leak free so far.
Diffuser all finished.
All car wiring nearly finished, just the lights left to go.
Sprinter solid flywheel conversion done (11kg lighter than the std CLK DMF).
Koso dash and sensors all fitted and working.
Harness mounts all completed.
Wheels fitted, went for 15" magnesium 5x112 SLK rims.
R8 coil packs fitted (lighter and more modern than the Merc ones)
Full service on engine/supercharger/diff/gearbox.
General trimming/weight loss throughout.

Now I just need to hide enough pennies from the wife to get the ECU and fibreglass/carbon on order.

Had some slow progress on the project, quite a lot of one step forward and half a mile backwards... but it's getting there finally.

Have weighed the thing and its sitting at 602kg (with a very heavy steel and plaster mock up body for moulding, from my estimates the mock up body is close to 60kg!). As it stands its corner weights are:

OSF - 152kg
NSF - 136.9kg
OSR - 152.7kg
OSF - 153.9kg

Other little jobs I've knocked off the list are plating the front wishbones to smooth out the airflow, pressure tested the fuel system, started swapping out bolts for titanium, reworked the throttle cable, have been playing with the aero and more general weightloss/simplification.

Was also lucky enough to have Bizzle come up to visit and do some footage for his YouTube channel, https://youtu.be/UnGp1w5nbY4?si=27DsuaNFF3G2w_1J />
Next things to tackle are sorting out the ECU and finally starting to cast some body pannels, have been putting this off for ages so time to bite the bullet.

Fantastic build, great to see so many pictures.

Considering using this engine myself in a project - you don't have rough dimensions for the engine to hand do you?

Cheers, Paul.

Hi Paul,

Thanks mate, it's been a nightmare since day one haha.

Will get the measurements later on this evening when I get back from work. I can remember it was 137kg with some modifications/deletes so not all that heavy either.
