Busa Cat
Guys what should I be looking for in a Catalyst for a Busa? Anything in particular or dosent it matter?
If I fit one, will I need a Lambda? If so what reads this? I have a standard ECU.
Thanks!
If its broke, fix it. If it aint broke, take it apart and find out how it works!

Why do you want a cat? for SVA? If so then you won't be needing a lambda unless you want a wideband sensor which can help no end along with your
power commander with setting up the fueling.

Yes indeedy, SVA looms, less then three weeks to go!  
Been getting more and more concerened about the emission side of things but might have sourced a system now that has a CAT in. Little bit of welding
and fettling and it should get me through SVA.
SO taking things to their logical conclusion then, can you fit a lambda to s system without a CAT and use it for tuning the fueling??

Yes you can, you will still need a cat for SVA, but you can take the cat out afterwards, and still use a closed loop lambda system afterwards. This
has the advantage that you'll never need to do a rolling road setup. Just fill in what kind of air to fuel to ratio you like and the system
regulates everything on the fly. Change your airfilter or exhaust and the system automatically makes sure your air to fuel ratio will remain at its
optimum.
I've got one of these for example: http://www.afrtuner.com/
