NZ Motorsport: Fun at the Trentham Autocross

Yesterday was another superb round of the Hutt Valley Motorsport Club LeMons Autocross series. The team at Home Built NZ entered the Sentra again but with a couple of mods...

Instead of having the incredibly restrictive factory airbox we removed it completely and just used the factory air filter on top of the carburettor. This improved the airflow into the engine by roughly 25 - 30%.

To help extract this air we made a custom cat back exhaust system that is far less restrictive than the factory "pea shooter" and muffler. This new system is completely interchangeable with the factory one and can be swapped back to factory easily when using the car for road use.

The awesome guys at Nefarious Motor Sport kindly donated a decal for the Sentra and it looks excellent. Their insane supercharged Corolla was also competing and sounded like a WRC car with the exhaust note reverberating off the hills. Truly wicked!!!

I was incredibly lucky to score a ride in Shane Windley's absolutely superb Nissan 200SX drift car which went like the clappers and was incredibly stable while drifting through the corners. A big thanks to Shane for this awesome experience and thumbs up for the excellent and strongly built 200SX!!!

All sorts of cars competed in the event such as these MX5's, stock R33 Skyline GTS25 sedan, S14 Silvia, Integra, Levin and MGF.

This little JDM rarity also turned up to the autocross. It's called a Mazda Autozam AZ-1 and is a Japan only "Kei" car. The AZ-1 is powered by a 657cc turbocharged three cylinder engine that develops 65 BHP and 85 NM of torque factory. This one is a rare Mazdaspeed model that features a redesigned body kit, uprated suspension, LSD and other minor upgrades.

This car is sort of like a miniature Ford RS200 with a hint of Toyota MR2 (there's also one in the background) and also a bit of Delorean with the gullwing style doors.

The big ol' Subaru Legacy tank was back in action again and put on a great show for everyone through the constant use of the handbrake.

This super rare Toyota Corolla GT sedan was also back in action and went quite well.

These are only a few snippets of the diverse range of cars that turned up and we will post more pics as they become available (I left the camera behind)

Overall, the autocross was another outstanding day and everyone had a lot of fun. The event was run seamlessly yet again by the great team at the Hutt Valley Motorsport Club. Thanks for reading and stay tuned for some more cool car stuff!!!
