My poor little 15g has probably given its best 2 sundays ago at Avon when it helped the T5-R to our all time best of 14.52 for the 1/4. With York looming and a few other mods and tweeks to do, I thought a turbo change could be on the cards. So I thought I just ask what currently, forum meembers might have avialiable and what sort of price there looking for ? Thinking that 16 or 18 T would be tops as I worry a 19T could damage it and I don't want to go too mad at this stage, if you see what I mean.
