The Monza we have is like the white racing car #58 that Oddball has shown us.
It comes standard with a 20XE engine wearing a Coscast head and the GM 268 high-lift cams. It is very refined and has thinker anti-rollbars upfront, sits 30mm lower than other Monzas(Belmonts), has full leather seats, electric windows, onboard computer, power steering, central locking and heated rear mirrors. The car puts out 115kW and 210Nm torque in standard trim and managed a topspeed of 221km/h at 6100rpm in standard trim. It wears the 15 inch Ronelle rims and is shod with 195/50X15 inch Continental sport contacts. The car sold from 1990 to 1993 and +_ 2'000 were made. They use the 3.55 F20 gearbox without the LSD configuration.
They use the Bosch Motronic 2.7 system with the SFi box and hot wire mass meter.
This is the most enjoyable car I've ever owned. Mine is red in colour and I had it for 4 years.
Right now I need that F28 crownwheel and LSD unit for my 1994 turbo 6 Kadett.
