This is a s4 TII engine. Is using one 20B housing and one s4 TII housing. When the engine was assembled, the rotor housing with the coolant passage on rotor housing, through manifold to turbo was put in front, the 20B housing does not have a coolant feed on the housing (its blocked/sealed). This isn't a big deal is it? I can just draw coolant from somewhere else? Wheres a good spot? Do I have to tap and run a bolt through that front rotor housing coolant passage now? I am going to be running the stock s4 turbo for awhile. The front rotor housing is actually the front rotor housing, hehe, its stamped with a F, and the 20B housing (in rear) is (i guess i got lucky when bought it) is stamped with a R for rear. Any help appreciated.
