I got a hx35 with a 12 cm housing for free so I decided to put it on my car. Here is my photo album http://s108.photobucket.com/albums/n1/2benchanted/Mercedes%20606%20turbo/ . I also replaced the glow plug harness and went with a full 3" exhaust.

I replaced the upper harness and took the battery out. I having problem with central locking system and the alarm is not working. I had the battery out for two days and now have this problem. Any help would be great will great will get more pics of the finished product.

Well I have been driving the last two days and working out the bugs got the door lock issue fixed was a fuse. I have fixed all the air leaks and now am getting 5 lbs boost by 2500 and 15 by 4000. Runs like a new car like to start to turn the pump up.

Awesome work and thanks for posting! I'm surprised nobody has responded yet...

Where did you get the header flange from? Also, what fittings did you use for the turbo drain line?

Is this driving the car down the road? I think the stock turbo for the OM603 in my '87 300TD is EXTREMELY small on the turbine side. I get 11 PSI of boost in park at 5100RPM!!! In second gear, going to 5100RPM, letting off throttle it is 9 PSI at 4500RPM. That's crazy the turbo spools that quick. I can only imagine what the backpressure is. This is also with a straight pipe exhaust ending at the end of the transmission.

BTW, Get that green coolant out of there and put the proper stuff in!

Yeah I machined the header flange myself I am a journeyman tool and die maker I welded the header and exhaust. The boost is alright while driving it I get 5 psi by 2500 and 15 at 4000 to 4500 so I only have it for a 1000 rpms but she really pulls. Free revving to 4500 in park I can only about 5-6 psi. Driving at 70 I get about 6 psi and she pulls allot better on the hills here in Portland nice big grades to check the torque. I still need to install egt gauge so I can start turning up the pump. Thanks for the tip on the coolant first merc. didn't know there was a diff.

Very interesting!! I'm glad someone has installed one of these... The boost numbers are interesting, and I can't wait to see how quick it spools with the pump turned up.

Would you be interested in selling the flanges and the oval cones?

No prob! The proper stuff is either from the dealer ($20/gallon) or Zerex G-05. The only place I know of to get the Zerex is at NAPA... Unfortunately you have to order a whole case of six if they don't have it in stock ($10/gallon). That isn't a big deal for me since I have lots of MB's... dunno if it is for you or not.

I would just keep your EGTs a little lower than what the turbo engine can handle and you should be fine. That's My $.02 anyway!

I have to look into making the flanges I made them when I was deployed and had axes to a machine shop.I have a friend with a shop see what he will charge for the use. I can get the transition cones but they are not perfect require some work to fit. I think the transitions cost 12 each.

That doesn't sound right... my '87 300D with stock turbo doesn't build any boost in park at any RPM, AFAIK. Sounds like you might have something else going on there...?

No boost while floored in park at max RPM? Normally, I'd say your wastegate is stuck open, but I know how meticulous you are about your cars, and you have performance figures to verify that the turbo is operating as it should.

Also, I only have a downpipe and the intake air is not pulled through the fender. That probably has something to do with it. FWIW, my '79 SD makes 5psi of boost at redline in park, and it has a full exhaust on it.

I would have sworn there was no boost with no load, I'll double check the next time the car is out of the garage... it's currently in hibernation.


I wouldn't expect that to affect things much, but I only have the rear muffler on mine. My engine has the KKK turbo, btw... most have the Garrett.

Hi,
I have a 1996, and previously had a 99 E300 turbo. The 99 had it's oil feed to the turbo coming out of the side of the block. Does anyone know if the earlier years have that same provision? I just havent felt around on the block yet. If not, Where are you getting your oil feed from?
Please reply

I had help from Jeemu he said to just tap the sending unit hole. I pulled the filter housing and tapped it 1/4 28 npt and put a t fitting one side for the sending unit and other for the turbo feed. The sending unit is not pipe thread but will thread into pipe thread and seal with plumbers tape. I had a custom feed line made and it was 34 inches long so I could rout it nice and out of the way.

Are you using the stock OM606 injection pump, or a turbo 603 pump?

Stock pump it runs good but doesn't have a alda but not much smoke on take off just in black puff and away I go. I can brake torque my 245 with no problem.

Pump is in Sweden having Dieselmeken work his magic. Just had another present arrive today. H&R bar that should compliment my limo bar.[IMG][/IMG]
