ko3 to a ko3s info please
« on: 01 October 2012, 14:02 »
changed my turbo yesterday, from the ko3 to the ko3s (quite an easy job when you have all the right washers and gaskets from VW), keeping the standard intercooler but changing the pipework to the blue silicone stuff, what kind of HP will it be once remapped? its a 1999 AGU 150bhp thanks in advance :) im hoping 200bhp will be achievable

any decent tuner will check your car over before they map it an if they dont think it will be suitable they will tell you  :smiley:

A different N75 valve will not give you more boost. A remap is the only safe way

ive decided to keep the standard AGU map (150bhp) on the ko3s it runs smooth feels just like before, but am i right in thinking with this ko3s running at 150bhp it will last longer because its running lower power than it should be  ?
