[urq] First of many urq questions (food for thought..)

[Justin]

Yep, here is a good write up from a very informative conversion site:
 Flywheel/clutch:
Any 5kt or 200 flywheel/clutch will bolt up to the 4kq tranny, so this is
not a big issue.  Although the standard 4kq clutch is a heavy duty unit, it
is not necessarily up to the task of handling forced-induction duties.  Best
to use a 5ktq clutch and flywheel.  One caveat:  the TQC and the 5000t/200
flywheels have the reference pins for the computer RPM and reference signals
at different locations, so only a TQC flywheel will work with a TQC computer
and a 5000t flywheel will have to be used with a 5000t computer.  They are
not interchangeable.  The TDC reference pin is one tooth more advanced on
the TQC flywheel, so if you use a 5kt flywheel with the TQC computer, the
timing wilt be retarded about 2-3 degs. and if you use a TQC flywheel with a
5kt computer, the timing will be advanced 2-3 degs.  The two magnetic
senders on the clutch side of the flywheel are not used for anything except
testing at the factory.  Also, the TQC flyweel is VERY heavy (>30 lbs).  In
comparison, the 4kq flywheel weighs 22 lbs. The lightest will be that off a
200, weighing in at 14-15 lbs.

> Yes, WX flywheel has the timing pin at 60 degrees BTDC.  The later cars
(MC, 3B, AAN, ABY, etc.) all have the timing pin at 62 degrees BTDC.  The
only effect of using a late flywheel with WX/WR electronics would be that
the timing would be advanced by 2 degrees.
