for those of you that have turboed EX model engines, has anyone messed with the vtec engagement, my vtec is kicking in at the same time as boost is, so its just one big *** pull.

I can really feel the "2nd stage" engage w/ my turbo. You can really here a difference in the engines tone.

most everyone i know with vtec puts the engagement around 5200rpm.. or a little higher ..... except the shop by my house that runs low low 10s.. they have toda vtec killer shafts in the drag car,,, no vtec = LESS tuning problems at big power

mine is like 4500, we are going to lower it, good/bad

You might pick up some more torque by lowering it.

I thought it engaged at 4600? either way, can't wait to feel it.

ive heard VERY bad things about lowering it below 4400rpm.... causes problems.. this is why they had LOTS of people hurting motors with the V-AFC when it came out.. they were setting the vtec at like 3800-4200, and getting BIG problems in doing so.,..

Honda had that point engage at 4500+ for a reason. People should just leave it alone and work out other details.

can u just remover ur vtech all together is it better to take it out with a turbo??

 
Rep Power: 585

its at 4000 right now and is running fine with the 13 psi after taking some timing out for the 13, thus making first and second gear useless, i guess u could just "remove" the "VTECH", but then that would defeat the purpose of the swap i did
