they cost 450 new. ko3 at 22 psi gives out 250hp with uprated intercooler and remap.
where you getting that figure from? standard k03 has max of about 210-220bhp
if you think about it, a k04 is in a 225 leon cupra r, and remapped 265bhp (from revo without an intercooler) so close to 280-290bhp with an intercooler
so where did you get 250bhp from a k03? k03's run outta puff easy
PS k03s will be inbetween
a k03/k03s hybrid would get you good power gains, and a k03hybrid can get close to 240/250bhp
saw one on ebay with 250hp and print out. had ALOT of work done to it though.
was it red?
if so it's benny's, and it was a k03 hybrid, not just a k03
ive done both 1.8t conversion and a 2l 16v ABF on bike carbs
if you need to know anything give me a pm and ill try and help...
btw... dont do bike carb conversion on a daily... mpg is appauling
1.8T is awesome
roughly 200 quiddage mate, made from stainless, if you wanted the vac nipples aswell, youd be looking at an extra 25quid inc brake vac nipple
other than the manifold everything else is fairly cheap to collect and will only cost about 200 quid to finish it off....
