MKG's Custom Single Turbo Build

Boosted Performance

I thought I could resist helping with this (since others seem to think I don't know what I am talking about)....but I can't.... as this is a huge fundamental flaw.


When you merge two banks together like this, you MUST use an exhaust flex coupler on one of the sides. Because (in this case) everything is rigid there is no room left for expansion/contraction due to heat cycling. Without a flex pipe the welds will crack no matter how good of a welder you are. The pressure in the exhaust pipes before the turbo in this case will be 2.5-3 times the boost pressure as well, that won't help things either.


Also, if you take my advice (and I hope you do), use the Vibrant turbo flex couplers (or simmilar). Do not use the flex couplers that have braiding on the inside. The coupler must be bellowed on the inside.

If the manifold/merge is not complete yet, and you do plan on doing the above...sorry, please ignore it.

Also, if yo are doing wastegate recirculation, same thing...install a flex coupler between the wastegate outlet and the down pipe. Same reaso as above.
