Yes 560Hp with stock rods & pistons and every engine parts is original and I just tortured the engine with 8000RPM all the time so M103 is ROCK
I just wanted to see how much the original engine can make hehe
Everything is just about engine system, if you can control fuel and ignition then you can make some power, good ingition curve is very impotent

Do you think there will be any problems boosting a 3.6L M104 to 400hp using an Autronic SMC ECU?

Yeah just like racing says autronic is very good system!
You should realy use autronic

Yes 400hp would not be any problem, with autronic and turbo you get up to 400hp with 0,5bar and stock compression.

What kind of turbocharger do you think to use?

I'm thinking of using a Garrett T04B 62-1 if I buy the complete turbo kit from this thread:
http://www.benzworld.org/forums/w124-e-ce-d-td-class/1270977-turboing-300-coupe.html
The performance target is 0-100km/h in <=5.0sec with stock 722.358 auto gearing and 3.07 rear ratio. How much power will I need to achieve this?

What boost level did you run ?

P.S. ooop never mind found the answer between the pictures - "
20 degree with 1,7 bar "

... the stock internals can handle quite a bit of boost

Joreto.
Have the E85 alky fuel in mind.

As i´ve stated numerous times.
As long as you keep out of detonation...

I just placed an order with Mercedes of Beaconsfield for a Turbo Technics twin turbo kit.

The production figures were approximately:
50 conversions performed by them
25 conversion kits made for 3rd party installation (many still available, including lots for the M103)
These numbers were divided fairly evenly over the three different engines (3.0L M103, 3.0L M104, 3.2L M104).
Price for each kit is £1000, much better than Willy Mosselman's prices. Call +44 1494 672 141 and ask to speak to John Pearson. Tell him Brandon referred you.

I'll try to document the installation process when the kit arrives.
I'm still trying to build the 3.6L engine but if I don't have that sorted out in the next couple of weeks I'll just keep the engine in stock 3.2L trim.
Either way it shouldn't be too difficult to achieve 400hp.
If anyone has any questions please post them here and I'll try to answer them. If I have time this weekend I might try to transcribe the reviews John faxed to me.

Just like Roman says...
It´s more or less all about engine management.
As long as you keep out of detonation(Ie;keep timing conservative) it comes down to total system flow.
As for innards,again..as long as you keep out of detonation the OEM stuff will carry a LONG way.

Btw.
Have worked with the autronics on occasions and they´re really good systems.

PUMPISH · #9 12-31-2006, 10:46 AM

ok...I have seen these pictures and for me it looks likes more low budget homemade turbokit. Not so good advertising to show out rust pipes and intercooler outside the spoiler.

But I am sure that maybe it works fine and good job as homebuiling kit.
But not good as a market product

Despite of the power its makeing, it has to be bling-bling too.

This is a sweedish way of tuning cars, I love it.

Yes i love "bling" BUT it doesnt need to be very blinky as long is not rusty and buckled

Å Roman.
Eftersom d nu skrivit om vårt svenska sätt...så skriver jag detta mest för att förvirra dem..så de inte hajar att vi e BÄST!

Speedtek · #13 12-31-2006, 05:11 PM

I agree the stock M103 can handle 600hp on stock parts. Just too bad the rest of the drivetrain can not.
