Cosworth Low Temperature Thermostat

9 Aug

High performance racing engines require upgraded and improved cooling systems for maximum reliability. One important component of the upgraded cooling system is a thermostat that opens to allow coolant passage through the engine and cooling system at reduced temperature compared to the original equipment thermostat. Reducing the temperature by approximately 10 to 15C compared with that of a standard thermostat, the Cosworth LowTemp Motorsport Thermostat improves coolant circulation through the engine by starting the process earlier than the original equipment thermostat.
Cosworth LowTemp Motorsport Thermostats are engineered with the optimum temperature range in mind for high performance racing use as it is very easy to over cool the engine by either removing the thermostat completely or using a thermostat that is not designed for the specific application. Additionally, over cooling can cause engine damage by preventing critical engine components from reaching their ideal operating temperature, altering the required clearances for safe operation. Another important feature of Cosworth LowTemp Thermostats is the ability to precisely control the flow of coolant when the valve opens. Unstable temperatures and even temperature fluctuation can cause severe engine damage and make it difficult to properly tune or calibrate the engine.
When combined with a correctly sized radiator and other high quality cooling system components, the Cosworth LowTemp Motorsport Thermostat will help to safely maximize engine performance by controlling the engine temperature at an optimum level.

Carbon Synchro Kit for 2004-2006 STi

27 May

The GD series STi 6 speed transmission was a god-send vs the previous 5 speed. But, Subaru still left room for improvement. In mid 2006,they changed the synchro design to a carbon based one, which offers significantly increased strength vs the earlier versions. These deal with heat much better, making it a great upgrade for the road race guys.

We can offer a full package that changes all the 1-6 synchros to the updated type. Contact us at z1sales@z1auto.com for details.

HKS Kansai Diffuser Group Buy Part I – Subaru!

8 Dec

We’ve been asked by a few members in recent weeks to conduct a group buy on genuine HKS Kansai rear diffusers for the WRX and STi. We are going to have both the 02-07 and the 2008 + cars represented in the group buy.

For the 2002-2007 guys, there are 2 basic types. The first comes with the exhaust cutout already predone, for those running stock mufflers, or similar oval type setups (Perrin, Apexi Worldsport, Tanabe Touring Medallion, etc). Some mufflers may need some minor dremeling for full clearance, but nothing that would be any big deal to do. The other type has no cutout at all, and this is best suited for those running any type of angled exhaust, exhausts with particularly large piping (APS 3.5 inch for example), and similar setups. This will allow you to trim the diffuser as you need to suit your particular setup. Again, the trimming is not difficult, and can be done with a dremel and cutoff wheel attachment, some masking tape. Each of the above types come in your choice of Carbon Fiber or Fiberglass (unpainted). Please note, that 200-2007 owners will need the additional fitting kit, and that is reflected in the pricing shown. Prices below [color=red]include[/color] shipping in the 48 states. For any location outside of the US, contact us with your full, complete address and we can look up the costs.

Group Buy Pricing:

HKS Kansai FRP Diffuser 2002-2005 WRX/STI – $849 shipped in the 48 states (cash/money order price is $825.00)
HKS Kansai Carbon Diffuser 2002-2005 WRX/STi – $979 shipped in the 48 states (cash/money order price is $950.00)
HKS Kansai FRP Diffuser 2006-2007 WRX/STi – $909 shipped in the 48 states (cash/money order price is $882.00)
HKS Kansai Carbon Diffuser 2006-2007 WRX/STi – $1039 shipped in the 48 states (cash/money order price is $1008.00)

add $64 to the above prices for Canada

For the 2008 + WRX/STi, the diffuser is carbon and priced at $979 shipped in the 48 states. Add $64 to Canada (cash/money order price is $950.00)

The Group Buy will close on 12/30/2010. Arrival to the states will be mid to late February 2011, and we will ship right away with tracking emailed. We need 5 people to make this happen (any combination of the above, just 5 total people), and I’d like to cap it at 15 people max, just to avoid any issues.

Payment can be made via credit card, check, money order, or cash.

Any questions, let us know!
