ko4 upgrade??
« on: 19 May 2015, 22:37 »
Alright folks. I've got my mk4 running a slightly modified stock lump (filter, forge d/V, Cat back exhaust etc.) And was wondering if I wanted to put a ko4 off a 225tt in place of my ko3s, would I have to change the injectors/rail, manifold etc and how much works involved??

Wouldnt say leave it for dead.  Well tunes k03s and a k04-023 there will only be 30bhp peak bhp or so in it.

If you have the full k03* mods for stage 2, id push for a stage 2 k03s.  But if your money allows and can get EVERYTHING cheap for k04, then go k04.

If thinking of buying a k04-023 and then buying add ons to make a 023 fast....consider a TFSI K04-064.  Then you leave most cars for dead on the road.
