Just Rebuild My 1999 Blaster

I have £200 to spend on doing up my blaster, ive got v force reeds and dmc alien fatty and silencer im in need of new back rims and tyres but they can wait for a bit :P any suggestions on what upgrades i should get
 
will i have to rejet?? i think i am anyway because am getting uni air filter and taking lid offf air box

anytime you are giving you engine more air you need to rejet, with a stock motor with a exhaust VF3's and no lid im gonna say you are going to be around the 300 range but you need to do plug chops to check.
