You have great taste in cars.

Have you seen the Raptor Twin Turbo V6 190E? It is amazing. 

Edit : I'll put a link for those who have not seen it.

Nice to see a w201 that's not black or "old man tan." What wheels are you planning?

If I end up going the EVO 2 route I'll be using these: Fifteen52 Tarmac Evo

Otherwise maybe AMG Monblocks or Penta style wheels.

I have seen it. Really phenomenal car! My daily is an EcoBoost SHO. If you look past the cam phaser issues and some of Ford's questionable choices like the internal water pump, they are really fantastic engines.

The caliper conundrum:

I had mentioned before that I had significant difficulty locating a rear passenger side caliper from a 400E to use as a donor for this project, ending up with two drivers side remans. So, I went looking for a solution.

The 400E utilizes a 278mm vented rear rotor, while the late model 6 cylinder W124s (with the M104) and early R129s use a 278mm solid rear rotor. The only difference I could find in the calipers is that the calipers for the vented rotor cars have spacers bolted between the halves. Armed with that "knowledge" I hit up rockauto for a cheap right rear caliper for a '94 E320 and crossed my fingers.

Here the calipers are on the bench. 400E unit on the left and E320 on the right.

You can see the bleed screw is on the opposite side... All that was keeping me from using the 400E caliper on the car.

I split the caliper and pulled the spacers from the 400E unit.

Installed the spacers in the E320 caliper.

and the end result is the needed right rear unit, setup for vented discs!

The brakes are done with the exception of bleeding. All rotors and calipers are on, and I installed braided stainless brake lines from Garagistic.

The 400E rear calipers fit perfectly, although if I was upgrading the brakes on another 190E or W124 I would be happy to just stick with the solid 278mm rotor and more readily available calipers from an early R129 or post facelift W124.

The front brakes were a little bit more of a puzzle. I had intended to use 400E parts there as well, only to find out that they require swapping to late model W124 lower control arms (P/Ns 1243303507 & 1243303407) in order for the rotors to clear the area around the ball joint. Having just replaced the control arms on my car, I ended up going with early (pre '95) R129 front brake parts. These do "bolt on" to 190Es/early W124s and gave me 4 piston calipers and 300mm rotors, a big step up from the stock 190E brakes.

The only adjustment that I ended up needing to make was to shim the calipers out slightly in order to center them on the rotor.

I have a power bleeder, so over the next few evenings I'll try to make time to get the brakes bled. The 190E master cylinder might be a little undersized, so we'll see how much pedal pressure and travel the brakes require once the car is back on the ground and rolling. If needed, stepping up to a bigger unit will be a straight bolt on affair.

Very interesting factory solution, using the spacers. Very cool that it was just "that" simple for you.

This car seems to be remarkably easy to work on, and things are helped by Mercedes sharing a huge amount of architecture between models in the 80s and early 90s. Makes it easy to do this OEM + type of upgrade.

A fairly unexciting update, but the brakes are bled. Did I open a bleeder without a line on it and spray brake fluid everywhere? Yes. Did I berkeley up the paint on one of my freshly painted calipers? Also yes, but fortunately on the back where you'll never see it.

Here is the bleeder in action. I found that rubber cap for the the fluid level sensor port on top of the reservoir was dried out and leaking under pressure, so I have it capped off for bleeding and a replacement on the way.

The only other thing to mention is a preview of the next project on the car...

Battery relocation? I cannot seem to decide where to relocate mine to. Was in the right inner trunk area in the W124. The 190 is less roomy.

Waiting... smiley

Battery relocation is it!

I'm not particularly worried about having a usable trunk in this car, so it may go dead center down where the spare tire would be. I think to go to the right of that would require some additional fab work to create some kind of shelf for it to sit on.

Battery is in place in the trunk and some of the wiring has been completed!

I'm using the setup Hennes Design shows to facilitate swapping an EVO/W126 coolant reservoir to the original battery location with their mounting kit.

This should free up a little more space to mount the turbo.

Next up is pulling the rear seat and figuring out wire routing through the car, as well as removing all the old trunk mounted CD changer wiring. The car has a cassette player. I'm guessing it wasn't optioned for a CD changer, but maybe Mercedes installed the wiring/cable for it in every car?

That coolant reservoir  kit is interesting, I'm about to order it for my car, thanks!

For routing the battery cables. You should be able to route it on the floor of the passenger side under the carpet. There is a plastic panel that runs from behind the glove box all the way back then you can do the rest to the trunk. At least that's what my car has.

I found the passage to run the battery cable through and have the cable run up to the firewall under the glove box. Where did you run the cable through in to the engine bay? One of the bulkhead pass-throughs by the glove box?.

I'm struggling to figure out where the cables for the CD changer go once they disappear in to the cable run under the seats. That isnt an urgent concern though. Once the car is driving I'll replace the cassette player and re-wire the speakers so I don't have to deal with the factory amp and fader.

Battery relocation is complete. Some minor trimming of the plastic trunk liner allowed it to go back in to place around the cable and 150A fuse between the trunk and passenger compartment.

I was able to run the cable the way yupididit suggested, through the factory wire run under the carpet and to the passenger footwell, where it fits neatly behind all the trim and heads in to the engine bay through one of the factory bulkhead penetrations..

I hooked the hot cable to the added fuse panel up front and test started the car with no issues. I'll run wire for electric fan relays out of the new panel prior to installing the coolant reservoir.

I'm happy with how the battery relocation all came together. I think with a slightly shorter battery I could easily install the factory cover over the spare tire well and maintain full use of the trunk if I wanted. So thats a nice upside.
