I indeed would like to apologise for any impression that I do not support Nitto's products.
In fact, I use them and have done so for many years with success. And as Andrew mentioned those guys went way above and beyond for me over the Christmas break a couple of years back when I had an issue (dodgy workshop, not their products). Their oil pump ate a bolt head and still ran for 000s of klm with only light marks to the pump. In fact the pump was working OK, the engine only died because sufficient oil volume could not get into the pump entry.
My point was, and I believe JEM also made it on the night, that you don't need to spend big (or maybe anything) on engine parts to achieve most goals. There were at least 4 examples given on the night of 400kw+ cars with standard bottom ends and mostly standard heads.
On the other hand, if you want and can afford 800kw atw, go for the Nitto gear and enjoy it.
