OK just bagged a pair of V6 Exhaust Manifolds, reason being I don't want to be chopping up the ones on my V6 Car.
I have looked at CLK 430 V8 ones, as @Turdo2
suggested earlier, also CL500 and S500 but they are simply not the correct shape to allow me to use the stock V6 Downpipes and Cats
This may be a RHD / LHD thing but my car has a very specific bendy twisty on the outlet just as it gets to the downpipes. None of the other V8 Cars Manifolds I have come across look anything like mine at the Rear of the Engine
In an ideal world I would be able to cut these twisty ends off and weld 'em to the end of the V8 Manifolds, but I don't think the V8 ones will allow that, they seem to be a different shape again at the back end they angle downwards where the V6 ones are horizontal or maybe even angled slightly upwards after the last Exhaust Port.
It looks like the best bet is gonna be to cut both so I use the rear 2 cylinders of the V6 ones and the front 2 cylinders of each V8 one, sleeve jointed in the centre, then butt weld the heat shielding across the joint.
I want everything ready so I can do the Engine Swap over a long weekend, initially the V8 is going on the V6 Trans and Diff, so I can be certain that any Electronic issues that may surface will only be down to Engine ME Version Coding.
Once we know that is all sweet, then swap Trans and Diff, and I know then that if anything now surfaces it will be due to TCU Coding !!
By buying 2 spare V6 Manifolds and doing it this way, I can still be using my R170 with the V6, and when the V8 Engine is outta the S Class and on my workshop floor I can get that job done and know for certain that it will bolt straight up to the existing Downpipes, then as it all gets down to the tunnel / underside of R170, the next pair of Cats will be removed and from there on will be a custom fabricated Exhaust system, done here in house
The Manifolds and Exhaust Fabrication will likely take a lot longer than actually swapping the Engines.
Left to buy now, is a 2.82 W203 C Class Auto Diff and the correct Drilled / Vented Front Discs to go with the S Class 4 pot Calipers, 330mm dia / 28mm thick / 46.5mm Height / 67mm Centre Bore with 112mm PCD.
I'll be pulling the trigger on these items very soon now, as a large cash injection is currently due in for the recently depleted "Project Cars Pot"
Project management ..............
When I break the S Class up soon I am going to need a lot of space to dry store all the bits, workshop has no space, so as we are promised a decent weekend weather wise I am going to clear out my large shed and burn all the old kitchen cabinets, doors and stuff I saved for when I built my workshop extension, a few years back !!
I have used all I need now, so the rest is bonfire fodder and other stuff can go up the tip in the workshop Van. This will free up a very large area for all the bits off the W220 that I'll be keeping.
Cheers for now, Dave
