MotoIQ Pacific Tuner Car Championship Series

Mike Kojima and the guys at MotoIQ have teamed up with Redline Time Attack to introduce a new wheel to wheel race series on the west coast called the Pacific Tuner Car Championship Series.

Are you bored with track days and HDPE events? Ever wanted to see what you have and go wheel to wheel with other tuning enthusiasts? Ever wanted to see who's the best driver and who could build the best car?  Ever then go to a legal sanctioned racing event only to find that your lovingly built street car is only legal in some super unobtainable class because of your tuning and the parts you installed?  Ever then find out that you can only race if you took off 80% of your hard earned parts only to race in some boring close to stock class?

There are going to be two main classes based on power to weight ratio and tire size. Tuner Under or TU which will run a 12:1 power to weight ratio and Tuner Over or TO which will run a 8:1 power to weight ratio.

You can also take your existing race car from many popular sedan racing classes in Grand Am, SCCA or NASA and with a little tweaking, be competitive. The rules have enough flexibility that nearly any unibody equipped race car can be competitive. If you are a racer from a restrictive rules class, you will probably find it refreshing not to have to come up with risky and expensive ways around the rules.

A full Draft copy of the rules can be found on the MotoIQ site.

MotoIQ Project R32 GT-R

R32 GT-R. A rare color

Eric at MotoIQ has a project R32 GT-R that has gone though some upgrades to help improve it over the stock R32 GT-R. If you have an R32 GT-R, or for that matter R33, or R34, or are looking for some information on them, I wrote some basics up several years ago.

To me, parts selection of any build is probably one of the most critical aspects of building a car. Other aspects are attention to detail, ECU tuning, suspension and chassis, etc. but that's another story for another day. The parts chosen for a build as a whole are probably more important than the individual parts by themselves. In part one of this build, I promised explanations of why I chose to use the parts I did. Some of the part names are also hyperlinks to take you somwhere for more information.

As a quick refresher since I wrote part 1 almost 18 months ago, this stage 1 build is basically everything you can do around a stock block and cylinder head without changing any internal components of the block or cylinder head. Why keep the stock internals? Because you can for a 500-600hp build as long as the engine is properly tuned and maintained. You can drive it, drag it, beat the crap out of it, and it still shouldn't break despite being almost 20 years old now. In fact, I'd rather keep the stock components than use many of the off the shelf American forged aftermarket components if I was planning to keep it under 600hp.

Tomei Oil Pump

The Tomei oil pump is the best wet sump stock location pump available for the RB26. If I have to upgrade, I want a Tomei on the car.

XS Engineering throttle seals for the RB26.  The stock ones leak, you probably will not even notice they are leaking.

Rear suspension arms with spherical rod ends.

After you are done with the basics, and checking out what Eric is doing with his R32, you can read over some more Advanced GT-R notes.
