    No problem. My reason for doing this thread was to show that these things don't cost the earth, and that you can do it yourself. It does take some time and care but its better than paying through the nose to have it handed to you on a plate! especially when you don't have to. You get much more satisfaction out of it that way too knowing it's your own work

    Cool beans well I fitted the new turbo today. Most noticable difference is its a load quieter than the old unit. Power kicks in just below 2000rpm instead of 1500, which I expected anyway, and it has a lot more midrange and top end power. Start saving for a custom remap and dyno soon then will see its full potential. One thig to note though is my map sensor is playing up, I think, so will have to get that sorted first, may ask a question on here.

    Incredibly useful!

    I can't see myself paying £1000 for a hybrid when for half the money, if that I can get similar results!

    Nice one dude!

    Just a quick update on my experiences on this so far...

    I have my donor turbo and have stripped it down. It's a slightly different procedure to yours, for a start my variable vanes are slotted onto the CHRA rather than than being bolted to the exhaust side of the turbo, which needed to be gently pried off.

    On the donor turbo you can see that some of the fins on the impellers had deteriorated and had small bits missing from them. Also the carbon buildup was quite bad (The turbo had covered about 80,000 miles to date), even though this unit hadn't actually failed properly yet (Although the play in the bearing was so bad that it would only be a matter of time before it hit the sidewall of the turbo so needs a re-build anyway.)

    The variable vanes are actually in pretty good condition and other than a bit of carbon build up they move nice and freely. I'm just going to clean them up and get as much carbon off as i can, then grease them a little and re-fit to the new CHRA unit. I'll try cleaning them up without disassembling if i can.

    How is your car going dead_Valentine? Did you sort the MAP sensor issue yet?

    Here are some pics of the stripped down donor turbo for anyone interested..

    Hi car is going well. Just over 700 miles since fitting the new turbo. The ecu has also altered the way it operates the turbo, being a learning ecu, so it responds a lot better since I first fitted it low down.

    Not sorted the map issue yet but I have BMWhat app for android and I have found a rather interesting way to fine tune my actuator by logging the data from the map sensor, engine rpm, requested boost and actual boost along with the duty cycle of the vacuum regulator which operates the turbo actuator.

    I'm just waiting for a bluetooth obd2 adapter for the car then I can sort that out but to be honest it cant be too far out.

    By the way I forgot to mention it looks like your having fun there. My donor was a lot more coked up than yours! If your after a cheap good ultrasonic cleaner they were selling them in maplins for 30 quid. I think mine is 35watts and I used their cleaning fluid, which to be honest was worth its weight in gold! Sea clean I believe it was called. When I first got it I tried the solvent, washing up liquid etc etc, the fluid made them all look weak frankly!

    Anyway keep posting and let me know how you get on

    Yes I'm having lots of fun with it at the moment

    My I have left a message for nkkturbos regarding a replacement hybrid CHRA but I think he is away on holiday at the moment so I'll wait until he gets back and in the mean time get to work on cleaning up the turbo as much as possible (my time to work on this is very limited, but I'm in no rush, but may take me a while to finish it)

    As the vanes on my unit fit by slotting into place, with no apparent guiding lines or pins I can understand why the electronic actuators need adjusting on each turbo. I've been in contact with a few turbo specialists but none of them so far will offer a calibration to turbo service. Fortunately the actuator alignment can be adjusted very easily even when fitted to the car (loosen the 10mm retaining bolt, twist adjuster and re tighten) so I may have to try and get it as close as possible when rebuilding it, and then spend a day fine tuning it once its on the car.

    Thanks for the tip on the ultrasonic cleaner.. I'll look into that...

    I have found a company 'Turbo Developments Ltd' who can calibrate the actuator to the turbo for a small fee using the ATD-1 tool.

    Can't wait to get this built up and fitted now..
