This kit is the only option out there for us and for the money, there is nothing that can touch it. Power DOES come on just off idle, not at 4K - although 4500 IS the sweet spot of the motor so you will feel it more at that RPM. Fit and finish are not perfect but not near the issues so many of the whiny shops have made out of it. And it the kit was finished to the nines, it would be $4-5K and there would be more complaints that it was too much - that is what comparable kits for other vehicles sell for from other manufactureres. I have installed half a dozen kits, never cut an o-ring and never had any of the leaks discussed here.

The instructions are fairly complete but if you do not have mechanical ability, you should not attempt. The manual is available for download on my site BEFORE you make a purchase. Alpine has been notorius for being hard to get a hold of buth they do offer a great product for a reasonable cost. Price from me is now $2899 plus shipping.

If you can get 5 people together, I can offer a group purchase price of $2699 plus shipping. And BTW, turbos also take power to make power - I look forward to seeing the real cost in time and money for that kit if it is ever finished.
