As it turns out, I am going to be using my turbo only for mild boost and
normalization.  Keeping that in mind, I am considering installing high
compression rotors in the engine that I am currently building up.  I am
talking a max MAP of about 40" but most of the time running a MAP around
32".  I do have an intercooler and see max intake temps of about 110 deg
F.  Street porting.

Who thinks this is a bad idea?  How about if I limited max MAP to about
38"  (5 psi boost)?

I think it is a bad idea Dave and so does Mazda. Even though the second
gen was limited to 5 psi boost they reduced the compression ratio.

Detonation is a nasty thing. Why risk it for little or no advantage.

BTW I just finished a book called Masters of Chaos. Iraq from
a ground pounders point of view. ISBN I-58648-249-I by Linda Robinson.
If you have any spare time while in East LA 12 on and 12 off or out
camping it would be a good book to read IMHO.

I had similar thoughts for the 12a I'm building. Street porting, +/- 4 lbs
boost, stock rotors. Bad idea? Input anyone? Thanks in advance. Andy

The 12A is another matter because of the shorter apex seals. Might
be OK but you are on the bleeding edge.
