Mercedes Turbo - Mal - 04-07-2013
Hello all
I have the option of acquiring a K14-2 from an E300 TD, part number 53149707026. It looks like it will fit an XUD, with a bit of fiddling, almost a straight swap
Does anyone have any information on the turbo? Or has anyone done such a swap? Information on the turbo itself is very sketchy
Thanks for any help or advice

I'm pretty sure someone used one, and with a load of fuel it made good power.
RE: Mercedes Turbo - 4WayDiablo - 04-07-2013
there really isnt much info out there lol, just spent the last 10 mins googling it
whack it on and see what happens gets my vote
RE: Mercedes Turbo - Dave - 04-07-2013
Im sure con67 has used a merc turbo, he gave it abit of exhaust housing reaming and apparently it made it really responsive. I think its a k14-2 or something?
edit: just re read your first post and realised you already knew the turbo haha. Spools about 3k im sure con said.
RE: Mercedes Turbo - Pompey306mark - 04-07-2013
Didn't an Irish guy make 200bhp on a merc 200 turbo.
RE: Mercedes Turbo - Dave - 04-07-2013
Im sure con is from over the water

Perfect! Just looked up con67's posts and yes indeed he used a Merc turbo
All the information I'm looking for is in this post
So it looks like this is getting the go-ahead from me, I was in the process of fitting a TB2509 but the elbow is probing to be an arse! Seems from the stats that the K14-2 is a bigger unit too
I'll make a build thread if there's enough interest!
RE: Mercedes Turbo - Pompey306mark - 04-07-2013
Yea but wasn't con.
RE: Mercedes Turbo - Mal - 11-07-2013
Might aswell conclude this! Just if anyone is in the same boat
Right.... I got the turbo anyway. Peanuts

Comparing somewhat to a GT15

It needs clocking but no harm t open up and clean the inside

It's almost a bolt on job, the holes are very close to lining up. Needs drilling to fit, there's meat on the flange for it

Wastegate sampling is not used due to the reverse wastegate Mercedes use. A good punch and a sampler from an old turbo fits nicely. Wastegate needs to have a bracket made up!

Somewhat finished

The stock line fits. I found using a Fiesta heater hose for the return line on a cut down alu return pipe works well

The Merc downpipe is mild steel so an adapter can be welded on for the XUD elbow.... Last on my list to do! Pity, I prefer the Merc downpipe....

When up and running I'll get it dyno'ed and see what it does
Last time was 115 but it's far faster since then....

what changes you expecting?

I'm hoping a fair difference! I put a lot of work into the pump on that engine too, I'll be happy with over 170bhp
even more with a stronger clutch!
RE: Mercedes Turbo - con67 - 12-07-2013
I used one but in the standard 306 housing so it was completely bolt on, I done 173bhp on the tmic. Just pump and turbo. very oem+ I thought lol
RE: Mercedes Turbo - Mal - 04-08-2013
Right, I'd better conclude this!
Turbo on
The downpipe needs an adapter plate, just cut the lip of the Merc downpipe and weld it onto some flat steel plate, drill then bolt on the XUD downpipe. I also bolted the wastegate shut as the arm uses a bolt, not a clip

Bear in mind with that setup it may still foul the gear linkage therefore 1st, 3rd and 5th will be a pain in the arse to select. Getting it done custom and binning that elbow someday soon
Driving defiltered so far. Finding a set of pipes to go to the turbo was a right pain in the arse so I used pipework from a Volvo S40 and a 2.5 Daily. Tight but fits well
As for driving.... I'm running a 11mm pump with advance mods, transit gov, lda grind etc. Boost comes in properly just before 3k rpm, quite laggy otherwise but it is a relatively big turbo.
I don't know the limits of this turbo, don't want to go too high so soon.... Currently running 24psi, controlled by fuelling
This is on a 406 btw, a floppy barge compared to a 306....!
I hope this was some help if anyone is thinking of using this turbo....!
RE: Mercedes Turbo - Ruan - 04-08-2013
Have you tweaked your governor yet?
Looks like it really dies about 4300rpm, need to get that engine spinning to 5k to get the most out of that turbo.

I have indeed, using a Transit main spring. Slightly more travel than a shimmed gov on standard spring though

It's early days for me, I was thinking of opening the wastegate a bit and winding out the max speed screw even more, for better response without overspinning the turbo. When I had this gov in the old pump it was very rev happy. I'll get it right though, just trial and error
Although this car weighs at least 250kg more than the equivalent 306....!
