Sounds like you thought it through. Thats good. Go with your
plan then. I agree partially with you but I feel the early 10vt
flywheels are EXCESIVELY heavy. The 91' 200 flat flywheel is
about 10+ lbs lighter but still a very heavy flywheel with more
than enough mass for the turbo application. I've driven a few
cars with that flywheel "including an MC in an UR-Q" and think
that it makes the throttle response much better and makes the
car a tad more responsive. The Balanced and Blueprinted 10vt
that I drove feels almost like a 20vt except it still runs out
of breath at about 6000 rpm unlike hte 20vt.
Anyhow, just thought I'd bring that up. The JT flywheel I
believe falls somewhere in between the two anyhow so that will
help some. I believe its
MC-2/3B Flywheel - 18lbs
4kq/jt Flywheel - 24lbs
5ktq/mc Flywheel - 29 lbs.
I did sucsessfully lighten a 4kq flywheel to about 20lbs once
before balancing. After Balancing it would have been a little
less. Just an FYI for anyone curious.
Good luck Eric, I love my KH 4ktq.
FS: 84' 4ktq KH motor, new paint (NOT MAACO) Selling to make
way for a 20vt ur-q.
