I just joined the list and understand that there has been some
discussion of turbocharger/supercharger installations.  If anyone has a
summary of commercial sources with brief descriptions/prices, please
email me a copy.

I also had a few other questions:

Has anyone dyno tested or flow-tested the stock exhaust system back of
the converter vs. aftermarket systems?  If so, how restrictive is the
stock muffler and tailpipe setup?  If it's worth changing, any
recommendations on sources/prices?

Does the ignition/ECS have a knock sensor? (i.e., will there be any
significant variation in output from the stock engine with increased
fuel octane above 97 r+m/2?)  (Haven't got the shop manual yet...)

Has anybody seen a nice leather-covered gearshift knob that matches the
leather-wrapped steering wheel?
