Garrett GT20 Project

[306Puggy]

Right, last update until next week. Dropped the plate off at the welders today to get the studs welded. In the end I sacked off the set screws and got some regular M8 30mm long 8.8 tensile strength bolts. He said to expect it done on Monday so there won't be anything until then. He did seem quite confused by my intentions though.

I also clocked it today which was literally a case of loosening the bolts and then turning the compressor housing with my hand. Being quite a new turbo, there was no rust or difficulty at all.

You can now see that the turbo is in relatively the right position compared to the exhaust flange:



One question, should I tighten all the bolts once I have set it up on the manifold or should I leave all but one slack so that once I get it on the engine I can have room for adjustment? Would there be enough access down the back of an XUD block to retighten the bolts? There are 5 around the circumference of the compressor housing. Also, would I need some form of high temperate thread tight on the bolts as well? It is one thing to simply tighten up bolts but to apply thread tight would make it impossible I think.

Edit:

Also found this blank off plate for the specific engine that this turbo is off (Vauxhall z20) but it is a bit pricey:

But considering I got the turbo for £65 pounds it might be worth it? Or would it be cheaper to have one fabricated?
