Re: VTEC kick in

should work on B and D series Not K, to be honest with you i wouldnt bother with them they only lead to other problems if the car isnt properlly modified.. Just down shift if you want to hit vtec sooner

Re: VTEC kick in

tested last like, definitely kicks at 4500 and then sounds like the inlet manifold does its bit approaching 6000, sounds almost like a louder vtec crossover

Re: VTEC kick in

Hiya mate, the B series engine in the MB6 has a twin runner inlet manifold, at 4500 it switches inlet runners and at 5800 or 5900 the VTEC kicks in.

Re: VTEC kick in

My old MB6 was like that with the exhaust and induction kit, sounded like the vtec kicked in at 4500 then another one at 5900. My new one doesnt have the exhaust on yet and it only sounds like it kicks in at 5900, possibily something to do with the exhaust valves?
