Has anyone rebuilt themselves a TD05-18G from a Subaru TD05-16G using Kinugawa parts.

Reason I ask, is that I have just been through the process, which included :

• Rebuild Kit (bearing/seals etc...)
• New Water line and Gasket Kit
• 18G Compressor Housing
• 18G Billet Compressor Wheel

But the Billet Wheel provided (18G 11-Bade Billet) seems to be the wrong one.
When fitted and the shaft night lightly tightened the wheel makes contact with the bearing housing/cartridge.

This wheel was provided by dealing direct with Kinugawa staff (not just picked off the website), as I was offered the 11-Blade or a 5+5 blade.

To me it looks like the profile of the base of the compressor wheel does not give enough clearance due to the larger 18G size of the wheel.

I would be interested to hear what Kinugawa part number you have fitted.

doesn't help you any but i always thought with the bigger wheel you needed the bigger housing as well?

I do have the bigger compressor housing for the 18G wheel, straight entry, just not shown above.
The turbo originated with a stock 16G 90 degree housing.

Hmm...searching around it sounds like the bearing housing needs to be machined to accept the 18g wheel......DOH !!!!! hopefully someone techie can confirm.

It is the right part you have been given the bearing/cartridge has to be machined to accept the new wheel thats all.

Hate to say it but you could of bought the bearing/cartridge from them with the new wheel all built and balanced then just fitted exhaust housing and compressor housing

Scott.T

Cheers, just confirmed that from various sources.
It's been much more fun and cheaper doing it myself, and realising there's not a lot in a turbo to warrant the cost of them.
I can get it balanced for under £40.

Need to speak to Bro-in-law about his lathe and 4-jaw chuck...........

Thats good then and yeah is fun doing them to be honest dont blame you for doing it yourself and even better if you no someone who can machine it. I did mine myself rather then buying a new cartridge, one thing i did on mine was opened up the exhaust gate and ported where the up pipe connects

The Kinugawa advert states the bearing housing needs machined.

Scott.T

iTrader: (2)

Link ?

It's been a bit of an oversight TBH.

piehole1983

I was gonna do what you are doing too and noticed it said about machining the housing so I didn't bother. I'll see if I can find it

piehole1983

iTrader: (7)

I don't see it any more mate, my apologies. When I looked in to this it did say about machining hence why I didn't go for it. I even emailed Kinugawa to confirm, which they did. I found it on their eBay listing initially.

FMJ

iTrader: (2)

Yep when I looked at doing it the ebay listed stated clearly that the housing needed machining. Put me off too.

Scott.T

iTrader: (2)

Cheers guy's
Wheels are in motion to get it machined. Worste case scenarion is it gets dremmel'd.

I did have a good look around Kinugawa's 18G's on the website last night and found no reference to any machining requirements. Perhaps they were losing sales as a result of that statement, hence removed it.

Most likely mate, but not a great thing for them to do! Good luck with it all anyway and post up some photos when you get sorted!

4-Jaw chuck in my works M/C shop has gone walkies, so their going to CNC me some compressor wheel clearance

Scott.T

CNC machined the bearing housing out to 72mm Dia. in my works M/C Shop, after a few facebook messages and guidance from John @ Braveheart Racing (cheers John if your reading)



Wheel now fitted and ready for balancing :

Nice one, looks good!

thanks for taking pictures. I've always wondered what actually needed machining, and it doesn't look too complicated

Is it literally a case of boring the old shoulder to 72mm?

Roughly what diameter is the cartridge btw? Just trying to figure out if my lathe is big enough

Good work! Keep us updated. I'd love to do something like this.

What are you doing with your old TD05 16g compressor housing? Could I do the same
with my TD04? Could I mate my TD04 turbine housing to a TD05 16g compressor to make a fast spooling hybrid?

piehole1983

iTrader: (7)

I'm not sure you could do that as the compressor housing is a good bit bigger on the TD05. You can get an upgraded compressor wheel and housing from Kinugawa for the TD04 though.

I mean use a TD05 16g compressor housing and compressor wheel with a TD04 exhaust housing and turbine wheel.
Cheers for the link, I've just been looking at Kinugawa's ebay website to find exactly that. I wonder if that is what is used to make the hybrid turbos so many people sell. And if not, are there any other manufactures that make billet compressor wheels?

piehole1983

iTrader: (7)

I know what you mean but what I was saying is I don't think the TD05 compressor housing will fit on to the TD04 cartridge/bearing housing.

As far as I know that's all that's done to make a hybrid, usually a bigger/better/billet compressor wheel.

Henrik

Unlikely that it will work - i seem to recall the turbine shaft is a different diameter (might be wrong, though), so unless you had some kind of bushing etc turned up (and it needs to be reasonably accurate, don't forget, so not something your average joe with a lathe can turn out), it'd probably not work.

The 18/19t wheels are popular on saabs, and they seem to work well. I don't think there's any reason why they wouldn't work on a subaru td04.

We were going to use the lathe and a 4-jaw chuck in my works M/C shop, as that would be needed to grip and DTI centralise it. However we couldn't locate the chuck so it went in the CNC.
Took the guy less then an hour to setup and a couple of minutes to machine.

Did you ever get this balanced? I thought that MHI wheels/turbine were component balanced, and not requiring balanced?
If it was balanced how much material was removed and where from?
Having just bought a billet wheel for my evo3 big 16g I am curious.
Thanks

Ba?

Did this ever happen?

Boosted, just an observation but the pic of the wheel fitted does say "ready for balancing". Im assuming he did.
