2005 Superlight Caterham, S3 Chassis with CSR260 Engine, SB100

[sltous]

 

Due to an upcoming family move to Europe, I am putting my Caterham up for sale.  As far as I know this is the only S3 chassis with the 260hp Cosworth engine from the CSR260 cars.  Whenever possible, I maintained the car with Caterham parts and bought extra parts to make ongoing maintenance easy. The Cosworth CSR260 engine is a great engine with good documentation from Cosworth and Caterham. California clean title in hand, SB100 smog exempt.  Asking price $48,000.

 

Located at Rocky Mountain Caterham in Golden, Colorado.  Please contact Josh at Rocky Mountain Caterham to view the car in person, either Josh or I can answer any questions about the car.  I've included some photos, you can see additional engine bay photos on the previous for sale ad on this site.  As the car is on site in Golden, Colorado I will do my best to pull from my setup notes and photos but Josh at Rocky Mountain Caterham will be the best contact for current photos.

 

 

Since purchasing this car, I have made no significant changes, only worked to continue to set this car up to be a reliable backroad car.  The torque from the 2.3L Duratec engine makes it easy to drive slow, and the 7700 RPM redline, rated 260 HP, and roller barrel throttle bodies makes it fun to drive fast.  I took it to Laguna Seca once and Sonoma Raceway twice.  I've owned the car since 2021, driving the car approximately 10,000 miles, for a total of 26,500 miles on the chassis.

 

Reliability Improvements:

• Installed differential struts to help reduce torque steer
• Replaced a failed driveshaft universal joint. 
• Switched to using a large Raceco muffler which required a small amount of fabrication as the Zetec - to - Duratec engine swap meant the exhaust system switched from the driver's to passenger's side. 
• Fixed a few minor electrical issues from 20 years of exposure to the elements
  • A bit of headlight wiring
  • The fuel pump failed due to corrosion on one connector
  • The O2 sensor was incorrectly wired
• I have done Blackstone Labs tests on the engine oil and differential oil and they passed with flying colors.

Hello, 

 

Is it a lowered floor or regular?

 

Also, what us the asking price?

[sltous]

Asking price is $48,000, I'll update the post to include that.

 

Standard floors, although I have a set of new, yet to be installed lowered floors included in the price.
