Just seen this on ebay,
http://cgi.ebay.co.uk/RS-COSWORTH-T4...item439e85f263
Has anyone useed them? I know of a good few people that have used there stuff on SR20s with good results.
Also I see it is T4 flange, I am thinking of running a GT30, I pretty sure they make them with T4 flange, is there any downside to going T4 flange rather than T3 flange?
