I was going to do a custom stage II tune w/ the CR170 turbo.
The tuner I bought the stuff from said the CR170 turbo would give me a much wider powerband, with more usable power at the top end than the stock turbo ever could.
I like that idea. I really don't want to break anything.
Smart idea. Not a good plan to turn your reliable car into an unreliable car for an extra 20 hp.
I also have a complete timing belt kit that I will also need to sell. All new VAG parts purchased from the dealer. I think it was close to $800 for everything.
I have everything that should be replaced while the timing belt is off: including the serpentine belt, tensioner, idler pulleys, all new TTY bolts, oil pump hex key, camshaft and other assorted seals, etc.. etc.. etc.. too much stuff to remember.
However I did not get a water pump as I wanted to use an aftermarket pump with a metal impeller.
Let me know if you want any parts or the timing belt kit. If so, make me an offer. Good luck with your Golf.
