Umm, that would be more than Jindabyne. I think I worked out 2000
would be at the top of the T-Bar at Perisher :-)

Pretty much, as I remember I took the Hilux when it was new and
*without* turbo there (1992 I think):

It sucked. Badly. Wheezed might be a better word.

Don't ask about the rego plates (they are UK issue/made with a
NSW issue rego. Things you could get away with back then :-).

These days the plates says something along the lines of hilux
and the front is 1994-1997 chrome issue, rice stripes on the
side gone. Same truck though, same condition, but with a turbo.

In those {high} conditions there will not be much of a problem
with a turbo. I'd back off on boost vs fuel delivery though -
around 6 to 7 psi is enough.

When you coming to pick up exhaust system which is still sitting
in the garage?

I love driving in snow =)

They look like you made them yourself with a bit of cardboard and a
texta.

As soon as I get a contract (job) long enough to save up some $$$ for
it =) What Uni do you teach at?

It is free, just waiting for you :-)

Nope, don't teach. Universities need general staff to tell
the academics what to do :-). Too much student interaction lately
though. The answer to your question is in the email addr :-)

For diesel, compression ratio will be dropped for direct injection
verses indirect injection. For the addition of a turbo it is certainly
not a requirement (I've not on my IDI diesel, and I've had a turbo
bolted to the side of it for more than 10 years now).

The injection pump on NA diesels tends to not have a clue on how
much fuel should be present for given load and atmospheric conditions
(ie: high altitude). A somewhat unsucessful HAC (High Altitude
Compensation device) was used.

With a turbo, you can balance the available O2 (as you actually have
enough to burn the fuel you want to) with fuel delivery and engine
load and end up with very good fuel economy along with performance.

Is that why my NA diesel is extra shit? (1300m alt.) =) Or do you
mean really high altitude?

Not that I can really compare it to sea-level performance. In the
areas of Sydney that I frequent when I come down, there are no
3km-long, straight inclines where I try to maintain 100km/h =)
