I agree, if its an RS Turbo, it will always be an RS Turbo, regardless of engine.

However, there is a divide between CVH and all other IMO.

Regarding the Zetec comments above, other than a few (and I mean a few, only three or four spring to mind), how many Zetec's are there that have actually put down a decent Top Speed? OK, for sprint times they have it pretty well sorted, but the larger capacity makes for better torque.

There is a very long-winded discussion to be had on the subject, but its all been done before.

I consider MY competition to be CVH engined RST's. If I were to take the CVH engine out, I wouldn't waste my time putting a Zetec in, I would go for something completely different. Thats not a criticism of those that have done it by the way!! Its just MY OPINION!!
