More power M117 4.5
Lets say I had money to spend. How would one go about turning the 180hp lug 4.5 into a 200-250HP or something comparable to the 6.9? Without putting a 6.9 in it. Using parts readily available to any one of us.

My thoughts:
I see limitations in the modification of the intake due to the design of the manifold itself and the fuel system. Exhaust would be simple custom headers, heads probably could get a tighter valve train and cams (any aftermarket ones out there?) and the ports could be matched and polished. Will 6.9 fuel injectors work in a 4.5? Rotating assembly balanced and lightened. My curiosity knows no bounds....

FWIW, my std Euro 1979 350 SE pumped out 151kw which I think is @ 205HP
The OZ 450's pumped out 165kw (but a whole lot more torque) which is @ 220HP. So, why not try source some Euro parts?

Not really going to happen with CIS, sorry.
Swap in a US 5.6 for a big bump in TQ and nice HP jump. Run the ECE manifolds (standard duals or the TriY) and that's about all you'll get. I'm sure you could source some cams on ebay.de if you wanted for more top end, but you're still limited with the CIS.

Yeah but how much torque is the M103 making at 2000rpm versus even the small M117?

Its the only thing I don't like about the M103....the lack of low end torque. My 617 can peel pavement off the road from a standstill it has so much torque....but the M103 just kinda leisurely takes off until it rev's up.

And the smogged out US 5.6 is about 100lb-ft MORE than the M103. Well compound your beef of that motor into a vehicle that has more drag and weighs more... I just do not care for the 300sel.

When I think about it, after having been able to drive both the diesel and gas W116's I'd have to agree with pawoSD and say that my 617 had alot better throttle response than my 117. But then I did have some tinker time on the 617. ahh hell I'll just make it a diesel..

I would keep the hood ornament and attach a 500E to it!

you should search my thread in the vintage forum. It's easy to do and I outlined a cheap way!

Swap to 5.6L block, go 100mm over bore (6L), P&P on heads/intake/ECE manifolds/various coatings etc.. Solid lifters on a HOT grind, spinning about 67-6800. With a properly tweaked fuel distro you can flow PLENTY of fuel to make this things Hum. Figure 325+Hp. More if you went EFI/Stand alone.

I would think just swapping in a normal 500 or 560 engine would be quite a boost....

Sure, a 5L euro or 5.6 US or Euro would give you quite the boost.
Won't be all That much worse then a standard car..it ALL depends on how hard/often you get on that pedal;-) You mentioned you had $$ to spend, and aside from forced induction/custom intakes etc that's about as far as you can reasonably go.. Jonathan
