Does anyone know who is making the turbo for the 2007 Mini?

[Ryephile]

I'm not sure, but there aren't that many turbo manufacturers so you could guess and probably be right. That said, the turbo looks to be a special footprint, so the typical T3 and T25 flanges will probably not be a direct fit.

I happen to have an image of the turbo, it's a BORG WARNER TURBOSYSTEMS (KKK) turbo.

[Ryephile]

Cool nice to know, thanks for digging that up!

Wow that is a cute little thing isn't it? LOL The wg actuator looks HUGE compared to the compressor housing!

[Bayliner]

Indeed it isn't really a large turbo.
But I'm sure there will be big turbo upgrade's in the future .

To put things in perspective, here's a nother photo.

Hi,

I used to deliver to Borg Warner were they make some of the above turbo thingi's! Well it looks the same anyway. I used to deliver to the Bradford Branch where they made them or some of them at least.

[Ryephile]

Wow that is a strange bolt pattern and turbine inlet! Add that to a snug looking compressor outlet and downpipe geometry, and nobody hold their breath for an aftermarket turbo kit. Those that do develop a turbo kit will have to impliment either a new exhaust manifold or an adapter piece. Also a new boost tube and downpipe will be part of the deal.

[Bayliner]

Yes, it's a nice looking manifold. (Maybee you know this allready) It's called twin scroll, the exhaust from cilinder 1 and four form a pair in the manifold and cilinder 2 and three also. This way the turbo will rev-up faster. You can buy twin scroll turbo's seperatly (it's been around quit some time). I believe Mitsubishi found out the concept of twin scroll.

With the Volvo t5 (5 cilinder) engine's this is also done, such a manifold looks pretty nice too. It has three separate exhausts inside the manifold.

[jjordan2004]

I was thinking it was BW who made the turbo, but wasn't sure. I work for them in the States, so you would think I would have known that. We mainly deal with commercial desiel applications where I work.

Hi Guys, looks like the cat shown in the second pic could fairly be changed for a decat pipe ,probably with worthwhile gains. The actuator body is quite small too so a larger (t3 size ) conversion kit could help too,for example if without any bleed off both actuators open at 12psi, a larger actuator has better control and resistance to fluttering before the theoretical opening point. of 12 psi . Actually its probably a 6psi actuator which means the exhaust gas pushing on the button valve in the turbine housing will be even more inclined to allow premature part opening.
Also notice the black capsule on the side. This is an integral dump valve/bypass valve/ recirc valve. On a closed throttle vacuum in the inlet manifold sucks on a thin pipe connected to this & pulls the internal diaaphragm back (against the spring ) releasing the the pressurized air from the compressor outlet side back to the compressor inlet side. BTW you wont here a whoosh as its not venting to atmosphere. Here is actually the best position for the valve to be for fast effective dumping of the air.
Its job? To reduce lag on gearchange and thrust bearing wear within the turbo. KKK's do not offer the same degree of mix n match potential as Garrett, but nothings impossible. First job is to crack the ecu to allow the boost to go up ,then its turbos, heads, intercoolers, etc etc

6 psi...

that's 0,3 bar of boost

get it up to 0,8 and then we're talking

[roland2003]

....a 6psi actuator does not mean the (standard) car will only give 6 psi. It uses an electronically controlled bleed off to up the boost (With VW Audi its called the N75 valve) -See my post on the next thread down 'Aftermarket tuning for R56' for an explanation.

Where did you get the pics? Have any idea on the model number or anything?

Just trying to do some research and confirm a few things. It appears I may have been mis-informed elsewhere that it's a Garrett unit.

Any specifics would be GREATLY appreciated.

[Ryephile]

hmmm, on 2nd thought, that compressor housing isn't the same as what's in the MCS, as the outlet elbow is pointing the other direction. Is the picture showing the PSA version?

[roland2003]

That piccy is a KKK turbo. Like you say the EVO uses twin scroll. We're lucky enough to have a brand new EVO turbo on the shelf and a new Renault 2L (prototype) unit thats also twin scroll. we just need the car now and some time to fit it.
You can change the radial orientation of both the turbine & compressor housings relative to the bearing housing (a long winded way of saying everything rotates)
Best Regards Roland GTT

[Ryephile]

Yes Roland I know you can rotate the housings, my point is the elbow on the end of the compressor outlet is pointed the wrong way compared to the MCS turbo. It's pointed towards the turbine housing, not away from it.

You can kind of see it in this pic:

[fozzy2k]

Would it be possable to fit the turbo from the s to the standard cooper? Havnt got a clue on this but its just a thought or would there be much more work than just the intercooler and turbo?

[Ryephile]

fozzy2k: The cost of just the turbo, intercooler, intake and exhaust work is more than the price difference to buy a Cooper S over a Cooper. This is kind of a dead horse issue from the last generation days where people always asked if the supercharger from the S could be grafted onto the Cooper engine. Basically, the answer is yes if you have the time and money, but it's a really bad value. The Cooper S engine has DI, different camshafts, and lower compression to better match the turbocharged setup versus a naturally aspirated setup. Add to that the fact the sensors and ECU programming is wildly different, and the Cooper now has Valvetronic, which is an unknown in the boosted world, and you have a recipe for trouble.

For what it's worth, you're better off financially and for your mental health getting a Cooper S if you want a boosted engine in a MINI.

[sixblade]

I would like to put a standard new mini top end on the new S that would be impressive but omg the car would be a disaster trying to get to run right.

Winding Road Magazine claims that the turbo is made by Garrett... is this incorrect?
