I can't answer that, but it sounds right.  I thought the major
difference in our engine was mostly in the cams and the lifters.

Which SR20?  Again, I can't speak for the SR20DE, but the SR20VE P11 was
11:0 last I checked.  I don't know of 'VE pistons would work with a DE
head; I never cared to look.

Why would you go to the trouble of importing Primera pistons when 300ZX
pistons are 11:1 and a little more common?  George Roffe's (incomplete)
web site about The Beast explains his SR20DE's transition from fun power
to monster power, and this was the piston he used.

I think a set of JWT S cams could be fun with big compression and
*might* be streetable on a manual transmission-equipped car.  Which cams
are almost available for us, again? :)  Mike Kojima has mentioned the
model a few times, but every time I try and save it something happens to
the message...
