I m an owner of a fully build - turbocharged honda.
The block is coming from Dart and the head is a ported fully opened GSR.
The engine is powered from a Greddy T-78 turbo kit and has only 5000 Klm on it.
My problem is that I have somewhere water leakage. For every 100 klms I m losing about 400ml of water and the thing is that is passing it inside the Cylinders. I have checked the engine block and the head twice for leakage test and nothing showed up. Furthermore I have changed flanges 4 times and still I see water passing in the cylinder.

 

Inlet manifold gasket? cracked sleeve? head gasket

 

check the exhaust ports and intake ports to make sure the head wasnt ported too much which can cause it to lose water. i knew somebody who it happened too so im just going off of personal expierence with his car. check the sleeves really good or have it checked by a machine shop if you could.
