When i built my F27 with a ZX9 motor in it i wondered why it had to pass car emissions test also,but it is a car no matter where the engine is from.
Anyway i failed the emissions test 3 times and got real pissed off with it all,i even had the company recommended cat in it.What i did was get the emissions set up properly on a gas analyser and it passed easily,so dont give up because the first time you drive it all the dramas will disappear in an instant.
