W123 upgrades?

Are there any "upgrades" for our beloved 123's that we can take from later model Merc's? Has anyone found a neat piece from some newer model that is a direct fit (or almost so)that will improve our cars and our comfort? I see rim changes on the forum all the time but I'm talking seats,radio,high tech gadgets,mirrors,brakes, ect.
Even if it's just an improvement to the fuel filter I thing we would enjoy finding out others experience.

Best to all![:)]

RE: W123 upgrades?

word is this is tough

heard of 126 bumpers being modded to fit
same with steering wheel...not sure of spline..

any rim really with a 25mm ofset should work - there are exceptions....

i hear / read that you can upgrade to 126 brakes, as the spindle is the same - have not doen it yet...

there are stainless steel brakes lines, drilled rotors...

really its up to you and what you can fit / make

im running a 270hp mutt with rack and pinion

Best retrofit to date...Code 248!

RE: W123 upgrades?

A few I could think of are:

* 9-bladed engine fan from W126 300SD (same engine)

* convex lens side mirror from W116 (MTUPower sent me one)

* sealed beam conversions for US DOT headlights--Hella or Bosch

* going Euro--lots of options here (headlights, heated seats, and the infamous trunklid triangle)

* upgraded breather hose for engine (Mercedes Source has it)

* covering your jack hole plugs (ebay)

* spare fuel tank that fits in spare tire (ebay)

* alarm designed for vacuum door locks (there was a thread about it previously)

* gleason torsion differential if applicable to w123's

* lowering (as per members' own specimens)

The rest are the same as what Jake mentioned above.

EDIT: Swapping major parts like engines from other models are also possible but limited.

RE: W123 upgrades?

karugs has some good ones there...

also a facelift to the grill...paint the innerpart black or dark grey...or skyblue - whatever you want...

you could add a "HOLLER AT ME SEC STYLE GRILL" - i dont think the proportion is anywhere near correct...but thats my opinion.

i highly suggest a sunshade that is fitted from carcover, or get it out of performance products...esp if you have a good interior / dash - this keeps cabin cooler...really.

there is alot of room for exhaust stuff...

yes you can lower it and add hd shocks, limo style swaybars, bushings....heck replacing ALL of the rubber will make the car feel brand new...

i have a ford overhead light in the stock location, gives better door open light, and two map lights...went right in...also running secondary fogs in the front - oh you could hook up the rear fog if its not running yet...and add a third brake light

once again these options are all up to you and what you want to do with the car.

Best retrofit to date...Code 248!

RE: W123 upgrades?

So far on mine:

1) Synthetic DOT 4 brake fluid, Synthetic Power Steering Fluid (with filter change), both Valvoline
Mobil 1 ATF for my manual transmission, Mobil 1 75W90 for differential and Shell Rotella Synthetic 5W40 for the engine.

2) Magnetic drain plugs engine, transmission, differential

3) Copper fuses

4) Copper/Brass & plastic radiator from Nissen's (Danish)

5) Wooden shift knob and steering wheel (later needs to be refinished before installing). I am considering putting "Wheelskins" leather cover of the steering wheel

6) Hella (they look closer to original) Euro light with clear side markers

7) About to install LED lights where appropriate

More on future plans later,
