what porting would you recommend to get 200 rwkw on a s5 t ii motor?motor is still stock,stock turbo etc.Or must i just up the boost,injectors etc.? Please help any suggestions!!!

 

1 horsepower =~ 0.74 kilowatt,
so 200 wkw =~ 268 whp

now you can reach this number several different ways, and you don't really need to port.
i don't suggest using the stock turbo or ECU though. if you upgrade the turbo at the very least you want some type of piggyback fuel management.
your fuel system will also need upgrade (fuel pump and injectors).

if you do want to port, just a standard "street", or extended port will work fine. you don't need anything crazy.

some of the other members who know more about turbos can chime in

 

Thank you coldfire for advice so far!Is it possible to give me the size of the port after its been ported say like how mutchgoing up ,down and to the side towards the waterseal?I have read that the exh port to port out,must only port the shape of the exh port hole after removing the defusser to the sides and up and down? Is this true?
