hi mate ive been fidlin about with rst,s over 10 yrs now and have lernt alot along the way the most valuable info i can give you is choose your tuner wisely your car/engine is only as good as the tuner thier are lots on here cant think why they havent posted on here offering help and advice must be busy, my tuner is ahmed bayoo i beleive him to be one of the best in the country so i drive the 200 miles to get my mota done properlly, thier are many different conversions to choose from aswell 250bhp is reliable done correctly my last s2 was about this power i cained it dailey and some at the weekends never let me down engine wise i think you need to do abit of asking on here about the various options you have, your engine will need a strip down and rebuild to a better spec your turbo will need changeing 5th injector, stage 3 head, these are all questions for a tuner because each tuner has his/her own combo of components they use for certain stages of tune so the answer is very hard, id say work out your budget first because once you start this game can cost thousands id say you could get 250 bhp from a 1600 reliable for about 3k,ish any other questions ask me or feel free to ring grove motorsport home of my tuner thier very good on the phone with advice and a top bunch of lads
