""""""""""""""""""""If you want big power all motor, you go with one of the big players in the cam game- Toda Spec B and C, or Jun Stage 2 and 3, and you accept no substitutes. All (or at least 95%) of the 225+ all motor whp B18s are running these camshafts.

How does this relate to VTEC crossover point? Well, the VTEC grinds on these cams are so aggressive, that the VTEC point needs to be moved up- way up- usually to 6500-7000 RPM. These cams will also make power to 9500+ RPM (READ: Built motor). Run these in conjunction with high compression pistons (at least 10.5:1), and you'll have yourself an all motor wonder. And this, friends, is where torque in Hondas comes from.
Why it doesn't all fit together

ok heres my question now what would happen if( "the above motor" with those cams and vtec timing set high) , the b18c was turboed? what performace issues would there be? would the vtec timing be set differently for more power gains? would you even use these cams? im jsut trying to get the deal with vtec , cams and turboing all in the same deal.................. help me out

 

why would u do that?first of all the cams that u are naming work a lot better with 11.0+ comp. so turboing that is asking for kabumm(big explotion). If you gonna spend all that money just get low comp pistons and turbo cams.
The spec C's,jun 3's; are all motor cams and will not will be the best choice for turbo(too much overlap).
peace

 

ok thanks i got it , i wasnt quite sure what was up
