I am considering fitting a kompressor to a standard 320 V6 block on a SLK but the consideration is only at the is it feasable stage.

Anyone know if it can be done easily? Is it simply a bolt on been as the SLK32 is fitted with the same or did the 32 have modifications done to the block to adopt the fitment?

I know the 32 would have other modifications to the head's etc but not sure if the flywheel was uprated etc.

Does anyone know someone who undertook such a mod?

AMG engines have never achieved their power output on the basis of adding one component such a supercharger , and are designed from the inside out with unique pistons, cams , fuel delivery systems etc etc .

You can`t hope to create a C/SLK 32 engine without spending far in excess of buying a C32 in the first place .

Both Carlsson and Kleeman have offered supercharger kits for the M112 V6 but I have no doubt thhat it would be cheaper and more satisfying to trade your SLK 320 for a SLK 32 AMG.

The majority of internals are different in the AMG motor, crank, pistons cams etc. ECU will be very dirrerent too with additional sensors and circuits for switching the blower in and out - as the previous postor said better off selling your 320 and buying a 32, like for like year and miles it will cost an extra 2 or 3 K - absolutely FA for the difference in the car. Saying that if you want a 32 supercharger with intercooler, air filters and induction boxes get in touch with me as I have one for sale!!

Add to what has been said a different gearbox, diff, suspension, brakes, exhaust and I think the fuel injection is a different system to the 320 Bosch setup. Get a 32 you know it makes sense and then you can upgrade that to 400BHP.

I have not stated that I wanted to transform a SLK320 into a SLK32.

The ECU is an intelegent module that adapts to the way you drive the vehicle or so I have been informed by a Mercedes engineer. I simply wish to give the car something etc by adding a supercharger I do not wish to turn it into a 347 bhp supercar. Finding a SLK32 with simular mileage to that which my motor enjoys would be difficult in that I have owned the car since 3000 miles and in the seven years that I have had it the total on the speedo is just over 40000 the car is mint and in A1 condition being garaged in all of its ownership and not being allowed out to play unless there is a blue sky.

I simply want to know if its feasable to simply bolt on the kompressor without modifications

Im quite sure the Mercedes engineer would put you right on the way forward with a very educated answer to your question.

I know where you are coming from. I am considering a Brabus large-displacement conversion for my 1999 SL 500, taking the motor from 5.0litres to 6.1litres (and from 308bhp to 426bhp). It would be much cheaper just to trade the car. But I have owned it for seven years and 150,000miles and don't want another car.

To return to your question: supercharger kits are available but there is a bit more to it than merely "bolting on" a supercharger.

The other burning issue with this type of project is that you`ll create a car no one wants to buy . The trade will value it less than a standard 320 ; people wanting a performance SLK will always want the real AMG and your insurance company will become nervous .
I just can`t see the raison d`etre .

You're right, of course, but if the man doesn't want to sell but rather wants to keep his car as a long term proposition just with a bit more power, then this is a solution. I know I want to keep my car but would rather like a bit more pick up, so when I can, I will "waste" a fortune on it making it even less valuable to the market but more valuable to me.

Have you considered looking at crossfire forums for this info. There seems to be quite a few of them and they like to tune and of course they share the same engines etc.

http://www.crossfireforum.org/forum/engine-exhaust...

Not a forced induction mod but tuning all the same.

Thank you r129sl it would appear we have the same reasoning that others cannot quite accept. The car is now 8 years old yet mint with very very low mileage. It would be pointless tading against a AMG the same age when you would not get a like for like milage and condition ratio.

The car is so mint that it is worth more to me than what I could get for it so to keep it makes a lot more sense. However, would like to give it a little not to much boost by fitting the kompressor if possable.

Its fitted to the 200 and 230 without AMG modifications so I cannot see why there would be on a 320

Well, you could certainly upgrade the engine without having to upgrade the rest of it, i.e., the brakes, suspension, wheels, bodystyling etc. I suspect you would have to reprogramme the ECU if only to deal with fuel metering and emissions, but this would all come with the kit. Other necessary changes would be to the intake manifold (obviously), presumably a pulley would be required, too. Whether you would need to change cams, valve springs, valves and pistons depends on how much power you wanted. I would have thought a gentle uplift could be achieved without doing so.

A Kompressor upgrade should be cheaper than a big displacement upgrade (I think Brabus did a 3.6S conversion).

There is a chap in the r129 forum on benzworld.org (posts under the name TechTune) who has added a kompressor kit to his SL500. He's done a lot more to it as well, but it is clear that the Kompressor upgrade could be done as a stand alone thing.

The suggestion about looking at Chrysler Crossfire upgrades is ingenious, I would never have thought of that.

Well if your adament about doing it, against the advice of the majority then steam on, although I sence a level of back peddling in your argument. With regards to my earlier point there are still immaculate low mileage 32's around that can be picked up for £11-13K. I recently sold mine for £12ish, it was a minter with only 37K on the clock, there was a very nice on on e bay recently with only 24k on the clock and he was struggling to get £13550 for it, so we can only assume it went for less than that. If you dont think you could get more than 8 or 9k for yours? then maybe you have a point. As for condition 32's tend to be very well cared for so the similar condition is psuedo.

Just trying to give you good advice

Carlsson do a 32K conversion that gives 300bhp and a non-kompressor conversion that gives 245bhp. Kleeman is on request.Brabus do a 3.8litre big displacement conversion which gives 280bhp. I have found Brabus to be very helpful and dealt promptly with my request for pricing and other info. Carlsson didn't bother getting back to me.

I`ve got to agree with catalina . If you get bored of a car`s performance , which you have , sell it on and upgrade .
There are plenty of worthwhile engineering projects discussed here on this forum , but this isn`t one of them . I`m a stickler for originality with Mercedes cars, but I appreciate the amazing products regularly turned out by Brabus , Kleemann et al .
If you want improved performance from an SLK , I suspect an engine management chip will be the best way forward ; easily reversable without building in unreliability and increased cost .

I have not given any hints of back peddling and have even emailed with regard to your earlier post of kit for sale. My 320 is unique and as quoted earlier is worth more to me than a sale value fitted with a Rieger body kit that gives the car a unique edge. I have since found out that the kompressor will fit and I am now looking into getting hold of various parts. I also chipped the car but its difficult to get a more out of a naturally exasperated engine, remaps work better to turbo'd or supercharged motors

Are you going to document the process? There are a lot of 320 and crossfire owners who might be interested.
