My '79 with a 1.6 and approx 95hp has hit around 120, verified by my friend
in his Vtec Integra.

My car weighs less than 2K lbs.

If the above were true landspeed record cars would only need 3 or 4 hundred
hp and  r&p ratio of .9 or .7 to hit 500mph, or a fifth gear of about .2,
or both.  Gearing will make up for hp up to a point, but not enough to make
a 3000lb car with 75hp go 150mph.

I think you need to revise your estimate upward a bit.  The VR6 Passat only
topped out at about 135-140 with 172hp.  The current Audi A4 with the 190hp
5V V6 tops out at 128 ( governor limited ).  If the car did not have a
governor, and it would actually hit the 6300rpm redline in 5th gear, it
would only hit 146mph.  It hits 128 at 5500rpm that equals
42.96mph/1000rpm, which would equal approx 146mph at 6300.  The A4 is
undoubtedly more aerodynamically efficient than the passat, at least it
looks like it is smoother.
