M104.99x turbo conversion

Post by ikrav » Tue 03 Nov, 2015 9:58 pm

Hi everybody,
Have tossed up the idea to do a forced induction conversion on a M104.99 engine for a while now.
Has anybody on here done this?
I've read about others doing it overseas, but want to hear local stories.
Are there any welding fabricators around Melbourne that can weld up an exhaust manifold, or will it have to be done using own man labour? (know that OM603 turbo exhaust manifolds fit M103, but none that fit an M104).
Technically speaking, it shouldn't be too hard, but am happy to hear any stories, advice or tips!

You could fabricate a 'Special' one to dump the exhaust into the turbo, and a full exhaust system to take it out without too much back pressure.

Photos, photos, photos --- Please?

Been there.... seen that. costs lots of $ to do properly. Apparently Melbourne is also full of ripoff know-it-all MB turbo mechanics...

If you do think about proceeding, I only suggest you do your research very thoroughly. We have a few threads here, mostly in the mod squad, but a search will reveal them.

viewtopic.php?f=30&t=4435

viewtopic.php?f=25&t=17348&p=128561#p128561

viewtopic.php?f=19&t=6200&p=46379#p46379

I would suggest talking to someone who a) knows something intelligent about forced induction and more specifically forced induction on M104 engines...

b) look at a 2jz - because it's a copy of the m104 anyway, yet 'prebuilt' for forced induction.

regardless of your motivation, reliable high horsepower forced induction versions of either engine are not cheap. So make sure you're aware of the financial implications before embarking.

Thank you Tony, and AMG.
I only know of one person (ART in Melbourne) who fabricated a turbo system, but it was for a M103.
I looked through all the pages on the MOD squad, but only saw the turbo coupe thread. Excuse my newness and not quite knowing how to search for threads.
Thanks once again for you assistance!

I would suggest sending a message to Ortolan, who provided us with inspiration from his build. I'm sure he can outline the costs involved, and also advise you on who to speak to (and who not to speak to) regarding the conversion.

There is a very very long story behind project hwa124 and not all of it is public info.

bottom line is a huge amount of $$$$$ was sunk into the project and some bad mechanic work in between, as well as MTA involvement.

As I said, it pays to do your research, as you do not want to end up in the same situation as others before you have found themselves in.

best of luck!

Don't worry about a exhaust manifold run a rear mount turbo and scavenge pump back to sump

What do you mean with the exhaust manifolds, anths?

Anths, as in one that is mounted almost at the end of the exhaust?

Yes , usually place them where the larger exhaust muffler would be depending on the car , you need to run a oil feed line to the rear and a scavenge pump to return the oil to sump, the intake is ducted as high as possible and you would run a smaller wheel on the exhaust side as the gas has lost a percentage of "heat" energy, Air feed runs parallel with the exhaust up to the throttle body.

This allows you to run stock exhaust manifold and essentially the greater part of the exhaust system with the removal of mufflers .

Last idea is not really good.

What would you like to know about turbocharging M104 enigne? I have done some... All of them were 104.992 EFI engines.

It`s really easy to have extra safe horses. 10.0 compression ratio limits boost pressure. I don`t recommend more than 1 bar of boost.
Above 1 bar of boost you should be really careful with ignition advance to avoid detonation.

Otherwise it`s very good and strong engine for turbocharging.

Good luck!

As mentioned above.
One member went this route and spent almost 6 figures of dollars to get it right.

Another member spent a small fortune on trying to turbo a M103 before giving up.

One of the main issues is the RHD steering box. A special set of exhaust extractors must be fabricated. The RHD box in the way compromises the issue.
