What does H.O mean?

The best gearbox you could get, which is basically bullet proof, is a Tremec TKO600

High Output.

Does TKO600 change well in high rpm?
Who sells those and what price?

Rod Tarry has one and I think he revs to 8200rpm or higher. You're probably best ordering one from America

Don't know, engine is not ready yet. Somewhere between 700-800Nm I think. I'm hoping to finish it for the summer.

Mine has a .83 5th gear the .64 is not suitable with a very large gap between 4th & 5th almost like falling off a cliff. Its an overdrive gear in typical American style.

True Rod, must be best to change the 5th gear.
I'm going to also use Sachs -765 PP with this one. That holds over 900Nm with sinter and is much nicer to use than multi-plate clutches.
