forge 007p diverter valve (not dump valve) makes more noise than the standerd dv but is nice and subtle not too 'look at me i have a turbo' kinda thing.
I know, i know, it's not that fast...but a darn sight quicker than me li'l 1.0 or the 1.2 clio! maybe i need to campaign for the 1.8T lol...back on topic i'll enjoy seeing what happens with this car (Y)
as far as bang for your buck goes, imo its a great car to mod, even upgrading the turbo isnt mega bucks because the turbo from the s3 is a nice pretty simple upgrade.
under 4 seconds is easily achievable with this engine, the big turbo kit is about £1500 tho! would rather save my buck for somthing a little more special (Y)
