turbo is the only option in your case by the sounds of that..
cai, extractors a good flowing exhaust, tune the af meter to 180ohms ( the best i could get, made it a bit rougher at idle but the computer says the mixture is perfect and it sure revs alot harder) and advance the timing to about 20degrees..
and the obvious, get rid of the slush box and get a manual. best thing you can do to speed it up
cypher, a standard Vl 6 cyl can accelerate well and do 200kph
surely that should be enough for any young driver, an advanced driving course and a set of premium tyres would help you stay alive longer and cope better with the power the car already has
The VL is now a cult car but remember that are all about 20 years old and mostly worn out
