This project is finally moving forward after a long pause.

The plan is that the metal fabricator will take the car next week and do the following:

- make brackets for motor mounts
- make a custom bracket for gearbox mounts
- make changes to Mishimoto radiator inputs/outputs
- add bracket for second ear on diff cover
- fabricate exhaust

Just got a delivery from Summit Racing, two of those:



Plan is to be able to have a LOUD exhaust on demand wink

I´m using coated stock S85 headers, dual stainless 2.5" pipes into a "H" section, then the cut out valves just before the Bastuck muffler I have. It´s got dual 2.5" inlets and dual 76mm tips, hope it will polish up nicely.

V10 at 8000+ rpm bypassing the muffler will be something else wink

Once this stuff is sorted I´ll have the shell blasted.

Good to see this progressing. Did you sort out the DCT software for the S85?

I haven´t personally but a friend has already done that in the US.

Also for those wanting to run this combo, Eliseracing will release a standalone in January that will control the S85 & DCT.

Some heavy CAD design going on (Binky style) to make brackets, none of the OEM stuff can be used because of lack of space!

Decided to splurge on some Supersprint hardware:





These are originally made for E46 M3, 2 x 2.5" - will incorporate into a custom exhaust. Old exhaust sold and will go into the car the S50 engine went into wink

The preferred setup is:

headers -> x pipe -> cutout valves -> mid box -> rear box

But due to space restraints the cutout valves might have to go between the mid and rear boxes. I want to have both the possibility to have crazy loud V10 and then a track day compliant setup also wink

But I have plenty time to figure that out, delivery is in week 11

Coming along nicely, space is indeed tight in that engine bay... it will be worth the effort though.

Love this thread even though it pops up less often than Halley's comet. It's going to be brilliant once out on track. smile

Slowly progressing wink

To be sure I´m compliant with German regulations I got some cats for the exhaust system:



These are 200 cpsi.

Fabricator will start working on the exhaust in approx. 2 weeks. After that is complete, the car will be stripped down to bare shell and bottom/firewall media blasted.

Also sourced an electric PS pump, the one from the A-class Merc - the dry sump system takes the place where the PS pump was:

Exhaust starting to take shape:











X pipe is coming behind the cats, then a middle box, then back box. Cutout valves will be in front of cats.

Some more exhaust fab pics. Was at his shop today and we did some final adjustments to the exhaust and exact tip location. OCD got the better of me/us and we will shorten one tip so it's more flush with the bumper.

Some more progress. Cooling system more or less done. Ended up moving radiator in front of the front clip and we modified a radiator so it´s got 2 seperate parts, upper/lower as the oem S85 system has. That way we can use the oem hoses/clips on the engine side. Then put a big electric fan behind the rad:











Then fitting the intakes, using the Eventuri ones:







So now the fab work is pretty much done it´s time to strip the car and blast the shell & fix some rust.
