T2, what\'s what, cracks, studs & fitting..
Turbo Mini Forums

Right! another bombard of questions, and I've already done a search on these things.

A) Are these cracks okay?





B) Why won't it fit?









Do I need to undo something and reposition it so it faces upwards like so..

Also what's been welded in the photo below, I notice the actuator has been taken off as well?



C) What are the correct studs to mate the T2 with the down pipe? (It's a mirage job)
D) Gasket, will paste do? or shall I cut my own out of some gasket material?






CHEERS!


If anyone has PDFs or documents with diagrams drop me a message.

A. Probably ok. Loads of t2's have cracks there. Not using the wastegate (the welded up bit) on the turbo makes it less important. Yours is set up to use an external one off the exhaust manifold.
B. Loosen the bolts and rotate the centre relative to the exhaust bit.
C. M8 usually I think but yours seem to have been helicoiled to something or other... they can be f##kers to drill out after years of heating etc.
D. Metal gasket, off ebay. You can't use normal gasket material.

The one with the external wastegate was just an example picture. The wastegate is what has been welded shut as he is using an external one.

should be ok my t2 was cracked and i didnt have any issues even boost was stable using an electronic boost controller.

yeah you need to loosen the circlip to rotate the centre section so the water pipes face the correct way. look up thread on here about need for water cooling.

my cracks were worse and is running fine.

My T2 came with studs

as said, metal gasket needed, i got mine off ebay

Cheers lads you are all stars.

Dan187 you mentioned the bit fouling is the water outlet or inlet. Is watercooling needed? I didn't think it was.

& cheers for the gasket (I didn't think about it being an exhaust and using a paper gasket, duh) stud and crack advice! All brilliant.

Thanks again.

Some people use watercooling, some dont. The way i think of it is that its there for a reason, they wouldnt have put it there for a laugh. Im definately going to plumb mine in for the effort it takes to do it, even if nothing comes of it.

like i say there was a thread a few weeks ago which higlited it and linked to a page explaining the importance and showed how to plumb it in correctly. You need it to self pump the water when the engine is off

Yeah makes sense, now is the time to plumb it in.

And the oil outlet feeds back into where the mechanical pump was on the back of the block, this then dumps the oil back in the gearbox ready for another cycle?


I'll get the T2 fitted properly first and then ask questions about what's feeding to and from where

How the hell is it supposed to rotate? I've undone the 4 bolts and removed those, under the 4 bolts were two metal plates which have also been taken off.

I understand it's threaded? so it's just a case of undoing it and rotating and then replacing the plates and bolting it back up?

Well the sodding thing doesn't move, i've given it elbow grease, had it in the vice, applied heat.. nothing.

Am I missing something?

Lovely! that didn't come up when I searched
