swapping rotor housings
Hey guys you all may know that I just crashed my N/a and now I only have a TII in restoration. Since the TII's oil seals went out on rotor number two I have to rebuild it if I want it to not smoke more than a pot junky. I have a set of N/a rotor housings with less miles than the TII rotor housings and I want to use those. I already know that the TII housing's exhaust sleeve does not have the little diffuser on it like the N/a's housings. I want to use my n/a rotor housings because they have ~20k miles less wear on them than the TII's housings. I am also away that the exhaust sleeves can be removed/swapped. So the only question that is left to be asked is are there any OTHER differences in the rotor housings from N/a's and TIIs? IS the water passages the same?
I'm asking because I have never seen a TII housing out of the engine or a side by side comparison.

Thanks!

TII rotor housings have a water passage that feeds the lower intake. This then feeds the turbo. You can use NA housings, but you must either drill he hole for the passage (the casting is already there), or get coolant for the turbo in another way.

Otherwise, the housings are the same. BTW, swapping exhaust sleeves is often a major pain in the ***. If you are really going to do it, just CAREFULLY drill out the locking pins, the thread the hole and use an allen head set screw when you install the new sleeves.
