    I've got a european Mercedes 190E with 2.0 litre 8-valve engine. I'm changing my turbo (K03) to a watercooled MHI TD04HL-13G-6 turbo. What is the best way to set up the coolant feed and return lines?

    Thanks

    Aren't these turbos used in Volvos?

    Tried Googling?

    Yes.

    Yes, and a few Mercedes forums, too.

    I hope somebody has installed a watercooled turbo in an older Mercedes.

    I've not heard of it being done before.

    Hopefully one of our more adventurous members will be along soon to offer advice or at least be able to point you in the right direction for more info.

    Good luck and when you do get it done be sure to post back!!

    I think member BTB 500 is an expert on turbo installations.

    Try a PM to him Tomant , Mark fabricates custom turbo installations all day long.

    Good luck

    No, you need to reach 30 posts. We had problems with PM spamming a little while ago, hence the restriction.

    I would just look at the heater return pipe from the cabin, assuming its a full recirculating system ie water still goes around with heater in the cold position.

    My old Renault TD used to have a small elec water pump which pumped water around the turbo for a few minutes after shutdown.

    Thanks Lynall. I believe the water won't circulate when the heater valve is closed. I could take the turbo water feed before the heater (with a tee) and put the return after the heater valve. The circulation pump with a timer is a good idea. It could cool the cylider head a little,too.

    I use the heater feeds on my Hondas - but I have yet to start the turbo conversion on the 3.2 24v TT

    However Janner on here has just finished the TT conversion and if he sees this it will save me having to get the instructions out for my kit :)

    Toamant the Renault was a 19 turbo diesel and there must be loads in the scrappers not due to rust like the mercs but some typical French mechanical failing!

    Already got a little circulating pump (20l/min). Maybe I'll put a thermostat in the return line so I won't need any turbo timer.

    Off topic: Didn't quite understand the thing about rust, though. My 190E YM 1990 has no big rust problems. Maybe it's an issue for the younger Mercs. I believe real Mercs have a number first and the letter(s) behind it in the tailgate, not the other way round like the mid 90's and later models.

    No no real mercs letter first:D

    I sold my old ren 1.9td to my brother in law and he ran it for a few years then fell asleep and wrote it off in a ditch, we cut it up for scrap with a 9" grinder and it took some doing the steel was bloody thick and very little rust the car was about 12 years old at the time.

    Whereas my current car has little bit all underneath nothing serious but its only 7 years old:(
