Garrett GT20 Project

[306Puggy]

Dude, please, put down the power drill for just a second. Go and do some reading around in the project section, see how other people have done theirs. I'd suggest getting it all into position and having a look at what needs to be where, does the compressor outlet point in the right direction, etc? I use a hell of a lot of cardboard and pva myself, it's great for making templates and mocking up brackets, means i can actually test fit stuff without doing anything expensive if it's wrong.

Think about the problems you're looking at, the solution is usually simple, for example: If the studs need to be the same length, then cut down a little where required, clean up the edges with a file and extend the thread if necessary, job done. Whatever you do, do it properly, it'll be a better end result for it. Fair play for having a go fella, and good luck.

I have read some of the project threads (such as cwspellowe's) but there is nothing showing how to actually measure stuff up and mark out the holes to drill. The cardboard suggestion sounds good. I need to find a use for that. You guys are so lucky that these practical things come to you so easily! I don't want to cut the studs though as I don't have anything to cut them with plus something like an angle grinder is too expensive and way too dangerous.

To line up the holes use a big flat bit of blue tack across the flanges, press together then pull apart and see how far out you were

Or get a bit of pipe thats nearly the right diameter, wrap it in tape till it is the right diameter (im guessing man and turbo are different diameters) then use that to align and a drill bit to mark

Thanks for the second helpful post Dum-Dum! I tried the pipe trick, the only problem is that the exhaust inlet on the turbocharger gets smaller and smaller as it gets towards the wheel. I guess I will buy some bluetack today and then post the results up on here to benefit other people who have not done this before. One thing I noticed is that the hole in the manifold is bigger than the hole in the turbocharger exhaust inlet, is that going to cause a sealing problem?

I can illustrate what I mean with this glass ceiling spot light cover:
