Yep, normally aspirated power too, no mucking about with superchargers or turbos or nitrous....

And did the job in nine hours, start to finish !

The car in question is a euro w126 300SE, 6 cylinder M103 engine, 188bhp.

The engine that I put in yesterday is from a Euro ECE 560SEC, 8-cyl M117, 300bhp. This engine has option code 822, increased power output.

I just have the wiring to do, which will take me less than a day.

I have a FULL genuine period w126 AMG exhaust system on it's way to me from Germany too.

And here's the best bit - the diff on the car is a 3.46 !!! Yee-haa !


I also fitted the lower body claddings color coded and genuine Brabus side skirts.

The front and rear bumpers I am changing tomorrow, rear bumper is a Lorinser and front will be an SEC bumper with integrated fogs, plus an AMG lip spoiler. All parts ready to mount on, I was just toooo tired yesterday !

I will also be retro-fittting the self-levelling suspension, which all 560's had as standard.

A couple of minor things to do - like the final sections of the power steering hoses, fuel delivery hoses, heater hose, brake booster hose, are all different lenghts for the M117, compared to the M103 that was there...but really simple to change over from the donor car.

Of course, the car will now be badged as a 560 SE - ULTRA rare model in the w126 range. It's all the power of a 560SEL without the crappy handling of the long wheel base model.

And with 300bhp mated to the 3.46, it'll be alot quicker to 60mph than either of my 500E's.

It's so rewarding - 112 bhp gained in a days work !

Wow-I am not surprised you are tired! Did you have someone helping you?

What was wrong with the donor car?

Really like the blue and the matching wheels on the recipient.

Is there really a big difference in handling between the SWB anfd LWB? My SE feels like a boat in any case!

The SE's look far more aggressive with the kits on them then the SEL's do.
P.S I wish Germany and Australia would swap places its a real drag not having that resource close to home[V]

The w140 S600 is there as a donor car too - the V12 that's going in my Widebody SEC !

The donor car for this 300bhp 5.6 M117 was absolutely fine - no problems with the car. It had a full genuine series 2 AMG bodykit too. HEre's what I did :

- purchased the donor car, a 1986 560SEC ECE 300bhp with full series 2 AMG ground effects, for 2,000 GBP.

- fitted the AMG side skirts and rear bumper skirt to my white 560SEC

- fitted/fitting the engine and transmission and all electrics and self levelling suspension to my '560 SE'

- parted out the donor car, interior, wings, wood, headlights etc etc for 1,700 gbp


So net result is I have acquired a 5.6 M117 ECE engine, plus full AMG series 2 kit for 300 gbp !

And I'll get a few hundred pounds credit for the remainder of the car that I am giving to the breakers !


cheers

Well done Talbir!!

Things I'm envious of:
1. Done in 9 hours
2. Access to clapped out full-on AMG cars for 2,000 gbp
3. THAT much knowledge
4. a FOUR car garage
5. An obviously understanding spouse that doesn't castigate you for spending 9 hours in the garage one day.
6. The 3.46:1 diff
7. did I say "done in 9 hours"?

Can you get a dyno sheet for your new beast? I'd be curious as to how much RWHP shows up.

Well done! I look forward to many additional photos and all the details on wiring requirements.[;)]

And yes, i love the 4 car garage and the available space to do such a transplant!

Soon you will have over 50 cylinders and 2000 horses on the lot!

Great work! You can't beat the dollar per hp cost of your conversion. A NOS kit would be more more expensive than what you spent and then you'd have to refill the bottle every other day. Too bad those deals don't happen in the US or there would be more Euro motors in our SEC's/SEL's.

Cheers Jim

There is a biturbo kit available for the 300SE - but it costs in the region of $3000 + just for parts. And it's only giving another 100 bhp.

I forgot to mention - the donor car also came with the original w126 AMG Aero I alloys - which were refurbed and now grace the '560 SE' as can be seen above.

Taking that into account, I literally got the 5.6 euro m117 plus tranny plus modules for free.

I echo the comments above!

I also like the color match of the body and wheels! It may not look as well in other colors, but I must give you your props!

You are the one and only, Talbir! [8D] Cool!

Keep inspiring!

That's incredible. Wish I had the resources to do that, but even if I did, I'd never get it past the smog guys.

Here's some of the mechanical changes I needed to make once the M117 engine was fitted in place of the M103:

- both heater hoses from heater to block

- both fuel delivery hoses (just the final sections, which are longer for the M117)

- both power steering hoses (final sections again, different angles on the M117)

- fitment of oil cooler under right side firewall

- throttle linkage, the main linkage arm running from under the brake booster to the throttle body. Longer and shaped differently for the M117

- radiator and fan shroud

- coolant pipe from coolant reservoir to top of rad

I removed the air con compressor and it's additional belt and tensioner - really no need for air con in the UK. I will retro fit at a later date, maybe...

Just the wiring left now and the retro fitment of the self levelling suspension.

Will update again on the weekend, which is the next time I will work on the car....at work in the office during the week....grrrr.....itching to finish this off....

The mechanical changes sound very reasonable thus far. Good luck with wiring next weekend as it should present some interesting challenges.

Cheers.

Thw wiring is easy - I have already pulled the wiring from the donor car, complete. I have played with the wiring on w126 cars for the last five years, so it's a very simple task of fitting the looms over on the 560 SE.

I figured out all the wiring on the M120 V12 engine (800 wires), so this is no problem !
