The trouble with that is that a 4K wasn't available as an optional motor for those cars. So at best, a 3K with 1166cc is the base, and a 4K scrapes in. (1166 + 175 = 1340cc)
Also, I beleive that the RTA goes down to the cc, not on the "thats near enough" principle. So that even if the engine is close to right, but still too big, it still won't pass.
