I am looking for information preferably in the Uk on where or if I can buy a Motorsport wiring loom & ecu for the S2000
or possibly a Inlet manifold to run it on carbs.
I would be gratefull for any information.

 

Carbs? You won't find anything unless you do a custom from a stock intake manifold.

Computers available at the moment connect directly to the stock wiring harness (Spoon, Mugen, Back Yard, Feels, etc)

If what you are looking for is a programmable ECU like Motec, Haltech, etc. those are widely available but you will have to tinker with a custom wire loom and the ignition system.

 

Can somebody tell this poor old dumb Texas country boy why anyone in this day and time would want carbs (besides NASCAR, of course)?

 

he probably wants to put in a open wheeler...
