My opinion on that would be that it seems quite a well made kit from first glance, however no de-cat/sports cat is included and neither is an intercooler, ecu, piping etc etc.
So i would say its quite exspensive. however bear in mind my knowledge of the saxo turbo market is limited.
It claims gains of 30-40 hp which seems about right, however remember you will ned to spend a LOT more on top of the price of this kit.
30-40hp can be got a lot cheaper by using NA tuning.
However if turbo is want you want. go for it mate
Just my personal opinion
