For those using a Matty or Mirage manifold with a GT17
Turbo Mini Forums

Just in the process of mating the GT17 to my Matty manifold. Before I make a fatal error, can someone please confirm if this is correct. Are people using 3 studs (the top two and one of the bottom studs) fitted into the manifold itself, and then leaving one stud in the GT17 (the one that cannot be accessed from the back with a spanner for the nut)????? Are people then drilling out the unwanted threads in the opposing hole on the bottom of the manifold????

I know this may sound complicated but I am sure some mebers will understand.

Any help or guidance would be much appreciated.

Defantly keep an eye on this im about to do mine

13.95 1/4 mile on a 2.95 fd. Carnt be that hard to beat!

A bugger, this reminds me that I never got a pic for another thread!

You can do it that way, or you can take a notch out of the turbine housing, so you can get a nut on it. I'll get a picture tomorrow of mine.

I modified the turbine flange as matty suggests to alow a nut to be fitted.

Just too a bit of grinding.

Don't just use 3 fixings, it will blow.

I have done the same and ground out the housing a little to fit a nut in. there is plenty of meat to go at with an angel grinder.

A man without a project is like a like a woman without a shopping list.

if space is tight could you not use a K-nut?

Thanks guys. I am glad that I asked and will try taking the grinder to the exhaust housing.

Matty, photos would be great just to gauge how much meat you have taken away from the turbo,

Also, this obvioulsy means that the turbo stud hole threads must be drilled out?

Here's what mine loks like.

I went the other way,didn't fancy hacking at the turbo.Seems ok so far.

'Where does the engine go?'

Ive done what matt did to fit it to my t3 mani, just gota go a tad more now.

Gasket or just a bit of paste between the two flanges?

a bit off topic but is matty still making these manifolds??

Thanks for the picture matty. You drilled out the turbo holes then?

Mattyc33 - I no longer have time to make them especially with the new arrival! I may do some more, when things settle down though.

Billus89 - yep the turbo is drilled out to 8.5mm

Thanks Matty. I will crack on tomorrow with some of the mods to the turbo. :)

Thats fair enough matty, congratualtions on your new arrival!

Ive moddified my exhaust housing to fit the metro manifold for now, but I'd be interested in one if you made any more. :)
