How did I learn so much? YEARS of malpractice on other makes, starting with

- 1956 Morris Minor Traveller, replacing the 803cc A motor with a 1622cc B
motor. Eventually the rear wooden frame rotted away and the old heap broke.
- building and rallying a series of Renault 8's, rebuilding various engines,
including a 140hp 1370cc R12 variant with twin 40mm Webers
- building and rallying a 70 Galant for six years, with 160hp 1750cc Saturn
with #5 cam and twin 45mm Dellorto's, trailing arms and big brakes.
- fixing a 72 Valiant 318-V8 wagon to use as the rally car service truck. It
was crappy gold and unspeakably ugly: we called it the Vogon (check the
Hitchhiker's Guide and the description of Vogon spaceships...). We put a set
of ute rear springs into it to stop it dragging its arse on the road. Even
loaded with rally gear it seemed to make little difference to the
performance.
- running a Aussie Ford Laser AWD for a year
- running a Mazda GTX AWD here in Canada for six years
- maintaining an 89 Eagle Vista 4WD for 10 years, including a 4G64 swap.
- and building my current 93 Eagle Summit GTX turbo.

Buy the Mitsu service manual and read it through.  Get a decent set of
1/2"drive sockets and hand tools, some ramps and a small floor jack.

Try stuff.
