well ive only just brought an immaculate and standard 29k small turbo model, its the one i wanted because i wanted the low down power, i also dont have any plans to modify my car but will just do small things like get as many carbon bits as humanly poss! i drove both models and the small turbo suited me better. The t25 is a great turbo, i absolutly love mine and im happy with my choice, but go for a test drive in both and see what you think!
