Here is a recent post by Rob about the C2 & C3 cams:
----------------------
My motor is internally stock, with prototype JWT C-series
cams and valve
springs. With the stock cams, UR underdrive pullies, *Gen
2* (smaller
diameter primaries = less high end hp) Hotshot header,
Hotshot
straight-through muffler, stock mid pipe, Hotshot CAI, and
*stock* ECU, my
'91 car made 120 hp at the wheels at 7500 RPM. It made 134
peak hp at about
6400 RPM.
With the JWT C3 intake and C3 exhaust cam, and all other
mods the same
(including ECU programming), the car now makes 168 hp at
the wheels at 7500
RPM.
That's a gain of 48 wheel hp at 7500 RPM, just from cams
and valve springs.
The ECU programming isn't optimized for the JWT cams yet.
I think we'll get
another 2-3 hp from the cams with more optimization on the
programming. I
also think that I would make another 2-3 hp with the Gen 3
Hotshot header.
So, I think that a 50+ hp gain in the upper part of the rev
range is
possible with these cams.
The C-3 exhaust cam lopes very heavily and costs a lot of
power below 3500
RPM. It actually makes more peak torque (at 4500 RPM) than
the stock cams.
For daily driver street use, I would recommend the C3/C2
cam combo. This
looses about 8 hp relative to the C3/C3 combo, but has much
better idle. I
run the C3/C3 combo on my car because it's not my daily
driver and I don't
care about refinement.
The C-series cams aren't available yet, but they will be
some time
relatively soon. I'd say upgrade to the Gen 3 Hotshot
header, get the
pullies, get a good muffler, add an intake, then get the
cams, springs, and
a JWT ECU.

Sounds good, no?
