    cooling uprades for GTX 951

    Hi guys just have a few questions about cooling upgrades for 951 rotax engine thats been bored out to a 1020. I bought the engine from the states and it has some cooling upgrades that i am not sure how to plumb into a standard system.
    It has a case cooler and i have plumbed it into the engine water delivery line befor the T piece for exhaust cooling and the out line for the cooler i have routed it to a T piece in the engine block drain line. Is this wright and should the out line have a restrictor in it?
    The engine also has 2 barbed fittings in the top of the head (deffinatly not standard) apparently thet are for water out. Can i just plumb them into any engine water out system and do they need restiction jets. If anyone knows of these type of upgrades any info would be great

    Just plumb those fittings to a couple of pissers out of the side, I also have a pisser for the case cooler other wise you don't know if the water is flowing or not.
