Shocks will help dial it out a bit. I personally run Koni singles. Can't
touch that rear bar in GS (the Type R has a 22mm rear sway vs. the
GS-R 14mm...hmmm, wonder why :)

Integra (now R :) racer in my region ran this setup last year. He was
not sure how much better the 225s were in the front (he ran V700s). He
did need to use a slight spacer to help the fronts not rub on the inside.
Full lock still had a tad of rub, but that is not that bad.

Well...you could just run ST and eliminate the GS-R suspension

Yes, finding where on courses to downshift to first is hard enough
in most cars. Its quite critical in any car with an NA engine such
as the GS-R.

It is and it does.

That's ok :)

It does it very well. Understand, however, we are talking a 1.8L NA I-4.
This is no stump-pulling engine to begin with. VTEC in this engine (like the
Civic
Si, NSX, and Prelude, a DOHC flavors) have a very flat torque curve from 3000
RPM to 7500 RPM.
However, power is a derivative of Torque, so peak HP is up around 7600
for these engines, and they are gear so that max acceleration is with redline
shifting.
So, hammering the throttle in 2nd gear humming at 4000 RPM up
a little hill will work...but its far better to drop it to 1st and redline it,
with a quick upshift to 2nd (dropping you to about 5500 RPM).

Lots is just a relative term. Relative to a non-VTEC 1.8l Honda 4, it
makes a bit less torque at lower RPMs (say 102 ft-lbs vs 105) but carries
its effective power curve much longer with a switch over to a more aggressive
cam.
To complicate matters just a tad, the GS-R engine (B18C is its mfg code) uses
a dual intake runner. The secondaries open at exactly 5750 RPM. VTEC cam
crosses over around 4400 RPM (it is dependend upon imput variables at
the ECU). 6000-8000 is where it likes to be.
It is not, nor shall it ever be, the mating of a Vipers low end with the high
end of a Ferrari V8.
