RS Motorsport :: Classic Speed Restored

Gday All.

Terribly confused as to which way to go for my MK1 build.
I want quick of course but would love to be able to fit into a few competitive categories.
I love the idea of duratec but that means no for any classic or historic categories only IPRA.
Then I hear of a potential Nd class being thrown around & my head is in a real spin! A pinto in Nd would be fun & not far off being competitive. But will Nd happen? Nc doesnt interest me as I dont want to go BDA or Lotus.

I could keep the pinto, build a super tough bottom end & use a YB head & race IPRA and then if Nd does happen I can go back to the pinto head.

So the big, possibly ignorant, questions;

Can you use the same pistons, rods etc going from a YB head to a pinto head (or vice versa)?
Would it only be a matter of changing the head and accessories over or am I missing something?

Thanks in advance.

Neither would end up with a decent compression ratio.

You'd need to change pistons, to get the best out of both.

How much money do you have to spend, I have just done this and am at least 11k + into my spend (head only + pistons.) not including the bottom end, then there is the $ up keep.
Duratec with rods, pistons, cams and injection will be a better option and its modern technology !
Or look at the US Cosworth site for Duratec they are fully developed with 280hp in a crate. Some times I think I should have gone that way.
