That sounds a little expensive to me as well for those parts only, but that also depends on the brand and type of turbo you get in the kit, is it an ebay $150 turbo or a Garrett $8-1000 unit? Wheres the wastegate? Intercooler and piping is just that, it doesn't matter if it's ebay or made of gold.

Doesnt seem like theres any sort of engine management either. Wideband? Injectors? Wiring? etc etc

You will need a clutch to hold the extra power, the stock one is no good.

Your local exhaust shop can fab you a custom exhaust for a few hundred bux. What does that manifold look like? Is it made for the 1.6 or you need to modify it to fit? Hmmm even with a high quality brand name turbo, that's outrageous at that price!

My entire kit with engine management, injectors, wideband, clutch, all the required stuff to make everything work, was under $2000 (granted i got a hell of a deal on the wideband, wastegate and bov) but still you should be able to assemble a much more complete kit for 2.6k

Thats just my opinion tho.
