My 1994 Black on Black Twin Turbo 300ZX, photographed along Hwy 1 near Los Angeles


I can say that this is most amazing car I've ever owned. Its so beautiful in appearance and in engineering. I bought the car in March of 2002 from a lady in San Jose, CA. She had certainly treated it with respect, it had never been in an accident and was completely stock (no modifications). It was garaged all its life and only had 54,000 miles on the odometer. Interior wise, it was totally unmodified and had the stock sound system with the Bose in-dash slot load CD player. It had a totally back interior with black leather to match the totally black exterior. My dream car.

Of course, after a while, I wanted to learn more about the internals of this fine machine so I began doing some modifications, starting with simple jobs, to gain more comfort working with this seemingly VERY complex car. This began with just changing my oil, filter and drain plug gasket every 3,000 miles, but has lead to much, much more. Even with all these modifications, the car shall remain totally stock in appearance. I dislike aftermarket body kits, wings, etc, with only the possible exception of some the things from the Japanese model of this car. It has a nice front bumper and tail lights.

This purpose of this web site is mainly as a documentation of all my work I've done to the car. It will contains large amounts of pictures, text, statistics, parts reciepts even fuel logs (yes, I've logged EVERY time I filled the car with fuel). I hope this will be a useful resource for others if they want a little extra guidance to encourage them to do work on their Z's and also just general interesting reading. If its detailed technical how-to's your after, others have solved that problem and have excellent documents on other sites. I will link to these and not duplicate their efforts. I may supply detailed technical how-to's on more obscure topics not covered by others. Enjoy my site, and thanks for your interest in my work!
