Since I'm using an M104 HFM engine in a car wired for a M103 CIS-E my mechanic said it would be a waste of money trying to get a stock E320 computer working.
It could be done but it would cost me more than the Autronic to set up.

Didn't realize what you are starting with.
I would tend to agree with the Autronic.
Will you have to install one coil per cylinder or will it accept the one coil/two cylinder on the m104 E320 ?

I think it should be fine with three coils. The larger issue seems to be the 60-2 trigger wheel. If the engine doesn't have one then I need to get one made.

I'm a past owner of a W124 300E with the Turbo Technics twin turbo set up.....its a great conversion and my car was still going real strong after 176,000 miles. The conversion produces lots of effortless power and the car was very understated.....if any of you subscribe to Mercedes Enthusiast magazine my car was featured last year.

Power wise the 12v produces 310bhp and the 24v 325bhp.

Hi All,

The extra power described naturally is appealing. However, what about the rest of the drivetrain?
How is the rest of the car, particularly the transmission, being upgraded to handle the extra power ?
I have a stock '95 E320 and the tranny just 'went' at 133K Kilometres (83K miles). From this forum I know i do not have an isolated incident.
I visualize great gobs of power ripping out great chunks of transmission parts.

I got the 16V 5speed. I dont think the norm is to upgrade the trans, thats a separate job. They are pretty weak though...

Waiting for the dyno chart, but it looks like around 144HP at the rear wheels for my 1988 M103 with 63K miles.

Good indication that the engine is still strong and within specification.

This would support the approximate 21% drive train loss as previously posted.

So far, so good.

As soon as I receive the chart, I'll scan and post.

My car had a new transmission at 90,000 miles and the second box was still going strong 86,000 miles later.

No diff whine...car was still on the original

New Head Gasket at 110,000 miles

Turbo's rebuilt at 100,000 miles

Lots of new radiators......car had about four, can't remember why it had so many, but was down to human error rather than something fundamentally wrong with the cooling system.

did anyone have any ideas about my car problems on page 2?

any help would be great

If you have any holes in the hoses as you stated, then that is problematic. The turbo provides a pressure output or boost which simply put, creates the added power. A hole will cause the pressure to be lost or diminished and will seriously effect your performance.

Will this kit fit the E36 W210?

The kits were made for the M103 and M104 variants in the C124 and W124.
They were produced by TurboTechnics for a U.K. Mercedes dealer (Hughes of Beaconsfield).
The kits were a "bolt on " that the dealer installed on new cars prior to delivery.
The U.K. motor press wrote extensively about these cars.
Physical fit was for the W124 engine compartment.

Kits have been on the dealers part department shelf since 1992, so that is why they have been sold at a deep discount !!

The E36 ( rare car...definite keeper !! ) is a late M104 variant.
Parts should bolt on the engine, but not sure of the W210 engine compartment which may or may not have enough room for the install.

Replacing the con rods is not really 'bolt on'.
What's the point of the new con rods? Is it to lower the compression or just to replace them with stronger ones?
The 3.6 con rods are already stronger than the 320 ones but I suspect the compression will be too high on the 3.6?
Would the 320 eprom work with the 3.6?

Space isn't going to be a problem as the E36 engine is going in the 320 coupe (w124)

For whatever reason Hughes was modifying the con rods for lower compression.
I'm not doing it on my M103 as the stock compression is 9.2:1.
The boost on the kit is about 7PSI.

Mosselman did not require any lowering of compression, but their boost was 6.2PSI ( not significant difference).

I think what must be put into the proper perspective is that the kits were produced and installed in the U.K. in the early nineties.
Strong possibility that the lowering of compression in the M104 variants was due to overall quality of gas in the U.K.

Worse case if you feel the engine with stock 10+:1 compression ratio would not accept the boost would be to install a thicker head gasket.

Not familiar with the piggyback electronics that come with the kit for the M104 variants.

Ortalan in Australia is doing a 3.2 M104 variant (HFM injection) but is using an after market management system.
Not sure what he has decided about the con rods.

Quality of gas in the UK at the time was and still is the same as the rest of Europe, ie standard 95ron and premium 97 ron, although you can now get 98 and even 100ron which is the devlis own brew and costs an arm and a leg.

Opinion on the shortend con-rods is that the engineering integrity on the Turbo Technics conversion is to a higher quality than the Mosselman kit....I've had cars with both conversions on them and the TT kit is better and was built with longer life in mind......Remember this kit was being sold through an authorised Mercedes Main Dealer at the time and had to meet the engineering integrity of MB as a whole, otherwise they would not have let Hughes offer the conversion.

As I've mentioned my W124 with a TT conversion was still going strong after 176,000 miles.....the only engine work that needed doing during this time was a replacement head gasket....but then again it blew at 110,000 miles which is typically when a stock M103 head gasket would blow anyway.
