That setup will run slightly hotter than a standard car unless you uprate and modify a few other things in the bay. However thats not really the issue at this point. you need to find what oipe has burst or what is leaking.

If it was running hot it can of course worst ways has signs of head gasket issues. If that was the case its possible thats where the water is now leaking from.

first find leak. If easy fix then come back update... If headgasket then remove get the work required done to head then come back before you attempt to fit or have fitted for some decent help.
