It certainly sounded very nice. laugh2

I once drove a Caterham 7 fitted with a similar engine. IMHO The Sigma engine with TBs really suited that car.



The Omex based TB conversion could be a very interesting option for my Sigma, if you would say that the high rev power will increase without loosing at least the now existing low rev torque.
