Last week I decided this would be a good thing to do. So I went about gathering the various parts.
1 x 45mm" to 38mm" 45' reducer elbow
1 x 45mm" to 38mm" 90' reducer elbow
1 x 70mm flexi joiner “Which was not so flexi”
Ok so my first mistake was getting the wrong size 45 reducer because on the Rev-D the secondary turbo outlet is bigger. Now looking back I knew this already but I was just following instructions here haha, anyway as I said I got the 45mm To 38mm which is too small, If you have a Rev-D I would recommend getting a 54mm” To 45mm” 45’ reducer, That might be a little too big but I will be getting one and trying it myself in the future.
That being said, it is possible to just use the 45mm To 38mm because that is what I did, it is just a true pain to get on when throwing the intercooler back on because they were a very tight fit.
This is the “not so flexi” flexi joiner.
Before:
After:
With the 45 reducer you can see I flipped it around and used the small end for the intercooler and the larger for the turbo outet. This ended up working ok but as I mentioned earlier it was extremly fidgety to get on because of how tight it was.
As you can see the joiner did not flex evenly and ended up looking horrible, it’s all lopsided and I’m not that happy with it.
Thats it, all done. i don't think there is a noticeable difference when just driving around the streets, however i did notice it holds boost into higher rpm better.
