I have questions about the installation of the seal blocks. Am I correct
in the impression that the holes for the screws should not completely
penetrate the outer housing wall?
Is there a measurement of where to start the cut away for the blocks?
thanks
C. Smith


It is impractical for them to NOT penetrate.
Be careful when torquing  them down as you could strip the threads.
Then you would have to install a heli coil.
Also if you pot the cavity with Devcon liquid aluminum or JB Weld  first
the blocks would be more secure. It is easy to bore through the Devcon.

True, you bore through the OUTER portion of the housing wall so that
there is a "well" to cut threads into, but I think C.Smith's concern may
have been over how DEEPLY does one cut THROUGH the thickness of the
sidewall WITHOUT drilling INTO the rotor chamber.

Not exactly. Here is the situation.

For a 3rd Gen P-Port Engine does it matter if you use 2nd Gen Rotor
housings?  I'm told that, if your P-Porting a 3rd Gen that, the 2nd Gen
Rotor housings would just as well... And they are a about $100 cheaper.

Yes. I don't think it matters.

There may have been other cooling mods on the 3rd gen housings
as it was a dual sequential turbo with up to 280 HP in the Japan
version. I don't know for sure.
