There's one of these in the club I autocross with. Very fast car...

 

My 3 Lotuses.
Currently I have a Hayabusa Tubocharged in the seven.
I'm going traditional setup.

 

[QUOTE=Wildncrazy,Aug 9 2007, 09:46 AM] I have been "involved" with several S2000 7s. If you can fit it to your dash supports the whole S2000 dash will transfer and wire up.

There will be a few buttons you don't need but it will work and in my opinion is better than many aftermarket gauge packages.

 

You can delete the cat. Simply pull the secondary O2 sensor out of the direct stream of the exhaust air so it picks up a far reduced amount by being out of the flow path. Since you'll clearly be going with a custom exhaust, drill a small hole in the exhaust pipe and weld a 2 inch threaded tube over the hole and screw the O2 sensor into it. Voila!

 

Sorry I haven't seen the 2 o2 sensors for the s2000
Is the secondary 02 sensor at the end before the tailpipe?

You mean, install the secondary far enough to fool the ecu?

 

Owning 3 British cars, you must be pretty familiar with Lucas electrical systems. :thumbsdown: lol. I'm just kidding, I can't say anything bad about Lotus. I drove an Exige last week, it handled like a shifter kart.

 

The secondary sensor is supposed to be following the cat to ensure it is functioning properly and reducing emissions.

Exactly, pull the sensor far enough that it is picking up a reduced amount and the ECU will believe everything is okay and that the cat is still there and doing its job.
