Without an LSD I did a 5.36 0-60 on brunters, timed with datron. Then when I fitted the LSD it did a 4.79 on slightly more questionable timing equipment. That was in a Corsa LET.
I don't think you can go faster for the money, BUT there are a hell of a lot of dodgy conversions. It will leak oil. Be prepared to spend, but parts never cost much. Have fun
