that kit looks pretty solid. not bad for the price. sounds like it comes with everything you need for a good setup.. even comes with gauges
What about engine management? IMHO, any monkey can put together a list of parts and call it a turbo "kit". To me, that is only 20% of the work. The other 80% comes from tuning and engine management.
This kit has also been relisted for a second time. Makes you wonder....
Just my $.02
