Water pump housing questions

I have a s5 t2 that I'm wanting to swap a half bridge s4 t2 motor into. I have a pfc so I need my housing since it already has the sensors installed. My question is will the s5 housing bolt onto the s4 motor? I premix so omp is not a concern.

should fit no problem.

Note: inquire about the Teflon ring and seal in the front cover.(not sure if it is needed or not,..I can't recall,sorry)
The gasket as well may need a slight trim near the oil pan but it will fit.

How much did they charge you to tell you it was trashed? Are they just doing the R@R and you are supplying the engine or what?

Am I the only one confused here? Seems like we're talking water pump housing, then front cover. What's going on? I'm not drunk, btw.

Well Im buying a S4 half bridge motor but keeping my 60-1 and all associated hardware. However, im swapping pump housings becuase i dont wanna have to tap another housing for my sensors.
Also the oil drainn on the front cover are they the same size? I ask because I have a AN fitting for my custom hose from the turbo.

if the engine bearings failed, the turbo and oil cooler are junk too. turbo might be rebuildable

Throwing away the Oil cooler. Turbo seems to be fine, no shaft play or catching. I do have a BNR stage 3 though I guess i could use if need be.

Most rad shops can flush the oil cooler.

Of course the cost of that might be higher than a good used cooler...
