IF you have the longer MC, then you can do the same MC swap I did (actually
use the '90 NOT '91 200q MC for less effort!).  If you had the short MC
than you could use the short MC from a V8 -- and have to fabricate some
brake lines like I did.

If your PV is fine, then you don't need to change it.  Mine was leaking,
and I wanted control over what was sent to the rear, so I went with the
racing PV.

>3)  What years/models MC work for upgrade?
The BEST choice is '90 200 with the spacer.  That spacer is important.  It
allows everything to just bolt up.  You also need the 2 bolts that hold the
MC to the booster.  They are longer on the spacer equipped cars that that
on you car.  I did my conversion at night when all the stores were closed
so I had to grind down some extra long bolt to the right length to make it
all work!  Save yourself the grief and get the bolts, too!

>4)  Am I missing anything?

No, since you will be upgrading the front strut housing to accomidate the
G60's which are not a direct bolt on to the 4kq (I read ahead).

Truthfully, you don't need 215mm wide tires.  Don't sweat that issue too
much.  I used/use 205mm wide tires on my urq on the track and that's more
than enough tire for the 200+ hp that car has.

I might remind you that if you will have more hp than a stock urq that will
be one formidable car because the '84 4kq has the 4.11 gearing!  Plus the
coilovers will really make the car able to stick if they're set up
correctly.  Don't ask me what settings to use; I don't know.  I have been
in cars with that setup that are done both right and wrong.  Wrong setups
are worse than stock!

Good luck.
