Larger valves installed.
Forged pistons are highly recommended. Approx $600
3" downpipe.
Methanol injection. I use this currently & would recommend: http://mysite.verizon.net/res11pgkr/vehicles/customkit.html
I have also used this: http://www.aquamist.co.uk/cp/cp1.html

It's not absolutely necessary to install lumps. Profile the cyl head intake boss to a minimum w/out going too far as to getting into the bolt hole. The turbo will force the A/F mixture past the intake boss w/out a sweat
This would be done if you are on a budget. Other wise install some lumps.
Small profile camshaft.
Depending on budget,& if it will fit, a SPA turbo exhaust manifold, or use a truck 292 2.5" exhaust manifold w/a "J" pipe.

I am pretty sure you can use a SPA manifold & run a flange w/exhaust tubing & locate the turbo where you want to.
Example: http://t6racing.org/t6racingbb/viewtopic.php?f=12&t=48
Just to position the turbo where you have room for a downpipe.

You can do something like snowman did & the chassis is simular to yours.
