AW11 (MKI) Supercharger Conversion

The day had finally arrived after much time and effort. There it was. The
first MR2 to be sold in Australia. The first AW11 to arrive in Australia
was back in 1985 for the Melbourne Motor Show. I almost purchased that one!
My white AW11 was sitting in the middle of Heidelberg Toyota's new car show
room. It had been a long six months since I had driven Toyota's test car
(rego# DGF 403). That was a lot of fun and I would have settled on that car
there and then! I was very happy with my car, but it could have some more
power.  Then I took my car to Winton for a sprint meet and to my horror I
had trouble keeping up with a 2LT Escort! This was new to me as I had been
running a GT Falcon in previous events. A supercharged motor could be the
answer (50% torque % 25% in horsepower?). Now I had a new quest, first was a
set of 16"x7" Simmons wheels with 195x50x16 008 Yokohama tyres. (A small
improvement)

A.P.I was just down the road from Porsche Cars Australia, where I was
working and I enquired on the availability of a supercharged engine and
gearbox conversion. It took approximately 3 months to find one, not from
Japan, but from the USA. I paid a deposit and waited. What arrived was an
auto engine with wiring harness, an intercooler, airflow metre, and a coil
pack. That was all. No gearbox or engine lid cover as promised. Would a
supercharged engine match to a standard gearbox and how long would it last?
The answer is yes and a long time. The next thing was to get a US workshop
manual for fitting the engine. As with most projects, they tend to drag out,
and this was no exception. Some parts had to be ordered from Japan and micro
fiche from the USA. This took approximately 3 months to complete, less the
engine lid  which got lost for a further two months. To fit the cooler and
engine lid cover, you have to move the battery tray 3" and the engine lock
lid 6" to the right of the car. It then took two and a half years to locate
a suitable gearbox with a limited slip differential. The standard gearshift
cables, starter motor, clutch/flywheel and driveshafts also had to be
replaced. A TRD "Quick-shift" kit was fitted reducing the shifter throw by
half. The car is now a lot more fun to drive than the standard AW11. 
What Next?  I wonder if an SW20 power steering rack and pump will fit into
an AW11??
