Hi mate, yes they're definately a rarity over here in New Zealand.
Less than 50 Cosoworths as far as I know, all parts have to come in the from the U.K so it's hard work sometimes.
But sheesh, there are so many Japanese Subaru WRXs and Mitsibishi Evolutions over here in New Zealand, that owning something rare like a Cosworth was a must for me
I think my cosworth is somewhere around the 350hp mark so possibly the .48 housing will not be right for me/
Cheers again!
