thanks guys, so it looks to me that 235bhp is a lot easier to achive than 250! and for the extra money to gain that 15bhp extra it doesnt seem worth while at the mo,
so im looking at
-ko3s
-forge TIP
-bigger injectors
-3" MAF
-bigger fuel pump
am i write in thinking i can get all of these from an s3?
also if i was running this setup with a quality map would i be stretching the boundaries of the ko3s? i mean would it be on its limits and be likely to go pop
For 235bhp you won't need injectors, MAF or fuel pump.
KO3s, TIP, turbo back exhaust, 007p & FMIC are all you need 
He has a agu so you are best off doing what wazzzer had just said.
The k03s is capable of makin 262+ bhp (it's has been done) its just you have do do everything properly (no bodging, Cuttin corners or doing stuff cheap.
You will want
fmic with 2.5" pipe work
Big tip
Pump
Injectors
Silicone pipe work
Catch can and pcv delete
3" downpipe and 2.5"+ exhaust
You already have a large port head and mani which is good!
A healthy turbo
Personally I would get rods to be safe but they arnt needed (not actually that expensive and around £350
Water/meth injection
Uprated clutch
Decent induction kit with heat shield and cold air feed or a smooth airbox with panel filter and cold air feed
Also you will need to port the manifold
That's all I can think at the min (may have missed somethin) but that should see around 250bhp
