im selling my zex(dry) nitrous kit to fund the gt4, it consists of standard kit (1 10lb bottle and fitting kit) maximiser kit (another 10lb bottle) and purge valve. it comes with 3 sets of jets 55bhp,65bhp and 75bhp. basically the complete kit. if anyone buys it with an st202 ill swap strut braces as mines been modified to mount control box. im looking for offers around the £450 mark but am open to offers. its a good bit of kit that looks good and performs well
