My Bisimoto D14a4 Level 2 Cam
First off why is everyone obsessed in turning high rpms to make power .You don't even make power till 8000rpm ,you won't make more power if you go higher rpms.If you don't make power don't go higher it's just plane DUMB

With the right parts you can make power till 7500-8000rpm aprox. You need to build an extreme D14 with level X cam and insane compression to even turn 9000rpm And still make power around 9000rpm.
If anyone is interested i've had a Bisimoto D14a4 Level 1 cam and i still have the specs of the cam here.In the meanwhile i allready have a Level 2 here.The level 1 was made for a D14 with z6 intake manifold and I/H/E .
The D16z6 or D16y8 cam will work on the D14 but it isn't the best cam for your D14.I've seen this cause of the differences in timing & lifts between the D14 cam and the D16 cam.A D14 engine isn't a D16 engine , a D14 has less lift and more duration then a D16 cam.You would make more power with a custom cam for your D14 engine.A sohc vtec cam will work but it won't be the best...Another thing ... the only difference between a D14 head and a D16y8 head with skunk 2 cam is the cam being better.A D16y8 heads flows the same as a D14 head or D16y7 head which is the same as the D14.D16y8 is actually a pretty bad head for good flow ,your better off with a d16z6 head or porting your D14 head.
