some interesting comments on this thread...
heres my personal opinion assuming that it has a stock ecu:
tune up
free flowing cold air intake
2.25 inch straight through exhaust
decent extractors (good luck!)
make sure the air-fuel meter, O2 sensor and speed sensor are all hooked up and working properly
aditional steps:
trd head gasket
head porting
and the biggest increase of them all: an aftermarket ecu
riojin: the blacktop head is a better casing but isnt "ported" from the factory. Also if you change the head your compression goes way down
