160Hp from a N/A 4000CSQ?

[Doug Johnson]

Are you speaking of power demonstrated on a dynomometer, or guaged through
your pants?

Jesse, IMO the figures on the Blau site are pushing it a bit, 160 is in the
ball park for a well breathed on 2.3 10:1 motor as Ben mentioned.   A good
port job, bigger valves (40mm intake), 270 cam or so, triple downpipe ala
4kq, 2.25-2.5" exh, free flowing filter (I know, but I think it makes a
difference when you're trying to squeeze every amount of flow.  I don't
think boring out the TB will do anything, its plenty big on these cars.  Oh
yes, I port the lower runners of the intake, blend the inlet of the TB (in
the manifold), and port match the ports.  No need to touch the exh.
manifold, not much you can do to it anyway.  Igntion is good as is, just
advance a little, run 91/92 and make sure all parts are clean and new.  This
motor should put out a solid 150 crank hp and rev cleanly to the revlimiter
about 6800rpm.  Anything more would require a 2.6 bottom end, at which point
about 170 is possible with much more torque.

HTH, lemme know if you have any questions.

4KQ 5cyl, by upgrading the cam, head, TB and exhaust. Does this seem
reasonable to everyone? Or is this a case of inflation to sell their
products?
