In this video, I show you how I separate a turbocharger. This is the stock JCW turbocharger from my 2009 Mini Cooper. It has over 100k km’s on it and it is indeed used. I will be splitting the turbocharger from the cartridge and showing you how to inspect it.

If you’re looking to refurbish your turbocharger, you can purchase a replacement cartridge, which will in essence make it perform like a brand new turbo. This is a cost effective way to get around from buying a new turbocharger from a dealer, especially a genuine replacement part. The cheapest price I found for a Genuine JCW turbo is over $1500. If you’re looking to have this done of you have questions about this process, feel free to email me and I will be happy to give you more information. While you’re replacing the cartridge, you can install a better one to improve the characteristics of the turbo, while also reducing turbo lag.

I was expecting to see a complete disassembly and replacing the seal. This was a video on how to paint your turbo.

@crazyDIYguy 3 года назад

Yeah lol I don't think he has a clue probably breezed through a forum thread and pumped out a vague common sense video 😆

@Deliriouskev 6 лет назад

you mixed up where the air enters the turbo. air from the intake goes into the turbo right into the compressor on front. the longer part is where it enters into the intercooler

@Stavo1420 6 лет назад

@silvermerlin6721 2 года назад

Yep and I'm just learning. Totally backwards

@gplusgplus2286 5 лет назад

You should also check your mounting surfaces are 100% level, as you would on an engine block. I've had a turbo that wouldnt stay mounted because of that. Of course check the exhaust manifold for level as well.

@jferguson907 5 лет назад

At 3:00 he's wrong, it's backwards on cold side. The Centric pipe sucks air inwards then impellor throws it radially and the eccentric pipe is t he compressors discharge.

@ExileZO 6 лет назад

@milanmastracci 6 лет назад

So what I used for the cold side is a similar silver paint that is only available at the local hardware store of mine. I linked the VHT silver which would look quite similar. If you are looking for a bare aluminum look that will not oxidize, you can sand the turbo / sandblast it, and then spray clear coat over top.

That’s fine! I just ordered some VHT, but it is just for hiflow cats I got.

u have make a very big mistake !!!!! the center hole of the cold side is the air inlet and the other 1 is compress air outlet.

@johnSmith-ee3rz 4 года назад

Man, so much misinformation. It's a disappointment because you seem to know more than the average person about turbochargers. But you should NEVER fill in with guessing what you don't know with 100% certainty. One piece of misinformation can corrupt thousands of unsuspecting people who don't know better. Same principle of how rumors start. Very good for TV personality though. Just wish there wasn't so much wrong info out there.

@chopjockey 2 года назад

2:40 Air goes the other way around on the compressor from what you said... It goes in at the center hole and out at the long curved tube to the intercooler / inlet manifold...

@360rocketz 4 года назад

3:09 The wastegate doesnt only open when you let off throttle, if anything its closed when you let off the throttle... the wastegate opens during full boost, to make sure the car doesnt continue building boost and blow the internals up. You realise the wastegate lets exhaust gasses out before it reaches the wheel, so that it reduces the flow to the wheel, making less boost build.

@MichaelR200419 7 месяцев назад

A wastegate is vacuum operated and opens when you let off the throttle unless the amount of boost overcomes the “spring” or actuator in which case yes it can also open under boost

Always check your turbo cartridge end play movement and axial movement. It should spin super free. Spin the fan with your finger quickly and it should spin at least 3 seconds.

Great videos but the amount of time and money it looks like you are spending wouldn't be a good idea to replace the turbo cartridge since it would have 130000km onit like you said. Seems like this will be a weak point in your engine now, just saying

@esvuu 5 лет назад

You don't have to balance turbine wheel after dissasembly if you haven't bent any of fins e.t.c. and also if you are not changing the wheel… I have taken so many turbo's appart changed bearings e.t.c. the vibration will be ever so slight, that it will last you minimum of 5 years, when the bearing will be worn out of vibrations.

@srdang6136 6 лет назад

Painting the hot side was quite a good decision. For the cold side, chemistry speaking,you are not correct, Aluminum actually oxidizes so quickly in very thin layer in matter of tenths of second, so painting here is just aesthetics.

@ForgedShaft 6 лет назад

How did you know where to locate the front compressor housing, because unlike the turbine housing it didn't have a dowel pin to locate it and could be put back on anyway. Unless you used the waste gate actuator to locate it somewhat close?

@milanmastracci 6 лет назад

Using the wastegate is one way to do it, and that would work very well, but where the 4 bolts mount to the cold side, they left a mark in the steel. The exposed steel began to rust and make the steel look different. So you can bolt it back together like that, or you can even put a mark / scratch on the cartridge and cold side to properly align it.

@johnbecker3159 Год назад

Agree with you....just buy new cartridge if any issues.

@alexlaverick6111 2 года назад

@Stavo1420 6 лет назад

I don't know about the ceramic coat of the turbo but heat is the enemy of all turbos so things like turbo jackets and ceramic coating don't really sit well with me even if they do keep the engine bay temp down because turbo cost alot of money.

@milanmastracci 6 лет назад

That is why the turbocharger is both oil and coolant fed. As long as you don't get the turbo red hot, and then park it, you're good. Letting a red hot turbo heat up the the oil in the cartridge and letting it sit there is what kills the turbo. As long as you let the turbo cool for a minute or two before turning off the car, you will be okay.

@Stavo1420 6 лет назад

milanmastracci Yeah but I'am also use to working with much bigger turbos like aftermarket RB25 turbos and 1JZ and 2JZ turbos which most of the time don't have coolant line just oil which barely does much for the turbos but keeps them lubricated, also they definitely get red hot.

Not sure you want to apply any heat stuff to the exhaust side of anything that’s cast iron. I know with exhaust manifolds they will crack when wrapped.
