Intercooling OM602
Intercooling OM602
I'm looking for a way to intercool my 1987 190D Turbo without hacking the car all up. Does anyone have any photos, examples, or ideas?
I thought it might be possible to mount a small SAAB intercooler in front of the passenger side front wheel, mirroring the way the oil cooler is installed on the drivers side. But this intercooler is very small- and I'm not sure if it would offer much advantage.
I personally think the best method for the W201 is squeezed in front of the radiator but I don't know how well it would work. Or hacking up the bumper and mounting in front of the lower radiator support will also work. But as for other spots unless your going A/W I dunno.
The hardest part is going to be welding a new flange on the intake or modding the cross-over pipe so that you can have an intercooler
There was a thread around here that had a pic of someone with a OM60X turbo manifold with a block-off plate for the crossover pipe and a 3" pipe flange welded on the other side.
Yeah this guy,

I have an eBay intercooler that would fit behind the bumper like that, but I feel bad about hacking up a 100% original 190D Turbo. Has anyone installed an intercooler without cutting into the chassis?
My suggestion would have to be a A/W Intercooler. Modded Cross-Over Pipe (delete egr) re-clock the turbo and mount the A/W intercooler above the turbo take air from the turbo to the intake. Put the new intercooler radiator infront of the air conditioning condenser.
edit: I had a stupid moment

Could use the AC to intercool, or use AC to chill water. no alterations to structure or appearance.
Running the air tubes is the most difficult part of adding an air intercooler. If minimum body modification is your goal then a water intercooler is the best. Routing 5/8" rubber water hoses is far easier than 2-3" aluminum tubes.
Äh. You dont need modified your car body at all if you want there at big cooler.
450x400x76mm cooler is just fine at w201 and w124 body Mercedes.
Its easier install air cooler than water to air, and its cheaper because uou dont need radiators for that or water tank,
(04-16-2010, 05:19 PM)jeemu its cheaper because uou dont need radiators for that or water tank,Only if you're buying new parts and a radiator advertised as being an A/W intercooler radiator.

(04-17-2010, 06:30 AM)ForcedInductionMight be, but there is a lot more work go water/air cooler than just air cooler.(04-16-2010, 05:19 PM)jeemu its cheaper because uou dont need radiators for that or water tank,Only if you're buying new parts and a radiator advertised as being an A/W intercooler radiator.

Tomnic I like your set up! That looks almost like it meant to be there from Mercedes! very clean!
(04-17-2010, 11:10 PM)willbhere4u Tomnic I like your set up! That looks almost like it meant to be there from Mercedes! very clean!
"clean" is what it will be when I finished.
But I am with Forced that it is not possible to mount an air/air on this car without cutting on the car or/and to keep the outside appearance stock.
The bumper has no internal space and to route the tubes from below will too close to the floor and will be visible.
The engine compartment of the 124 is kind of closed.
With my set up there is no need to cut something and the tubing is very short.
On top I can get these ICs for 150 EUR as many as I want, so the set up is reproducible.

(04-18-2010, 02:26 AM)tomnik But I am with Forced that it is not possible to mount an air/air on this car without cutting on the car or/and to keep the outside appearance stock.Thats my point. I had to cut out one of the radiator crossmember braces and part of the headlight backplate to mount the A-A on my 240 and keep the external appearance looking stock, and even then I could just barely squeeze 2.5" tubes through and it required 6 90* angles with 7' of air travel.

I wonder if this intercooler would fit where the cross over pipe is. It would need only one 90* turn.
I doubt it would clear the hood without adding a "power bulge".

(04-16-2010, 03:17 PM)casioqv I found a website link with somebody playing around with intercooler possibilities on a W124, but none of them look very promising to me:
http://www.124performance.com/images/SuperTurbo/
They did have an example of how the Saab intercooler might fit. I played around with this at the junkyard last week, and I'm not so sure it would work because it comes so close to the tire, and the plumbing would hang so low to the ground:
I already own an intercooler like this, but he really hacked the body and bumper up to fit it:

With the stock injection pump, the IC is almost irrelevant... just add an EGT gauge and take your foot off the pedal when it gets to the wrong side of the dial. Now if you're going to put in 6mm elements (or larger), then yes, an IC would definitely be a good idea... along with a larger turbo! Have you turned up the pump already? Remember that there's no power gain just by adding the IC...
(05-08-2010, 07:31 AM)400Eric and then see what the intercooler does.

This is good topic for show at someone little bodywork is easy and someone it inpossible. If you really want good water/air cooler. You need Cooler, waterpump, radiator, water tank and of course some wiring, boost pipes and water lines. These if you want at that works like it should.
And if we talk about putting cooler in w201 orw124 you dont need to cut anything to put in there 400x450 or 300x600 air cooler and 2,5" boost pipes
and that all you need.
at least on my 124 603 turbo there is only about 3cm space between A/C condenser and bumper support. Even the fan is without protection grille on the lower part to fit behind the bumper support.
The only thing I could imagine is to re-locate all the coolers towards the engine.
Next, I don't see a possibility to route boost hoses/tubes unless you go below all the stuff but this in conflict with the underneath engine cover and too low at all.

Well, like I said, turning up the pump will make the power. The IC won't make any power, with or without the pump turned up. The IC will keep EGT's down a bit, that's all. I've been running with my pump maxed out for years with no IC, I just know to watch the EGT's if I'm climbing a long grade or something.
Dave, what's the quickest 1/4 mile E/T you've ever gotten out of your OM603?

That is wise to do if yoy turn pump up.

Maybe you could also use the large thin intercooler from a turbodiesel Volvo 740 intercooler.
Remove the aux fans.
Make some new brackets for the water radiator and a/c condenser.
Move the water radiator and a/c condenser as far back as the clutch fan will allow (or delete clutch fan and install a big and small eFans).
Place the Volvo intercooler in front of the A/C condenser.
Volvo intercoolers are known to be restrictive junk. Poor cooling for their overly large size and weak tanks.

we never got the intercooled version of the D24T powered 740 Volvo on this side of the pond.

I was thinking of something like this. Just search for Volvo intercooler on ebay and there are some intercoolers there.

Yes, that is a turbo gas intercooler, the only intercooled Volvo 740s we got here.
BTW, the seller is in error, that isn't from a 90. That's the improved intercooler that came out in the 92 M.Y.
Again, the O.P., Tyler, does own a turbo gas 740 and I'm sure it was one of the first intercoolers he measured to see if it would work in the Benz. If it was a viable option, he would have mentioned it.

(05-16-2010, 01:15 AM)Deni Would it be better as no intercooler at all?

Any intercooler on a 201 is going to require cutting *something*, so if it doesn't want to cut the car, forget it.
Water injection doesn't do squat. I saw a power gain when injecting huge amounts of methanol but that was due to the engine burning the methanol as fuel. I removed the system from my car - waste of time, IMO. There was zero reduction in EGT's. Seems to work great for the diesel trucks with direct injection, but not so much for the OM60x.

Do air to water and use the condenser itself as the heat exchanger.
Course it looks like the fins have been able to cram ordinary fat air-air intercoolers in that spot on w123s and w124s. Looks like the condenser, fan, and brace were removed to make way for those. Hmm, a w201 turbo probably has way less space up front.
You'll have a hard time finding thin air-air intercoolers.
the new beetle and corrado ICs are compact thick and small. i got one off a g loaded corrado. pm me if interested.
