well.

its like this. i think you would make more power and save more money getting the cam and a cam gear for the y7 head and getting it tuned as opposed to buying the head and having it installed. the bisi cam will be bigger than the vtec lobes on the y8 head and it will be like vtec all the time. .. the auto to manual swap will make a hell of a diff. and a cam. but now the ? is.. how are you gonna regulate your fuel. this is obd2 so tuning ecu wise is out... e-manage ultimate? apexi -safc2. fpr.? idk

why would you swap the head? and end up with less power than putting in a cam that will give you in the end result more power. that is what's desired. more power. and its always nice to save money. so he'd have to buy the head. and pay some one to take his old one off. put the new one in. buy the ecu.and have them wire up vtec. . when instead he could buy a cam and cam gear. have the cam installed. have the timing adjusted and make more power for less trouble/money. doesnt seem like a good arguement that Vtack owns you. unless your just bored and kidding. if so.. please disreguard. =-) thanks

I vote swap the head. The bisi cam y7 will get you more power now, but once boosted, you will be able to make more power with the larger valves in the vtec head. So if you plan to follow through with boost, y8 head, but if your staying NA, bisi cam your y7.

Well, if you're going to get the cam, then you also need tuning, and the dollars run pretty fast...
If you're getting a vtec head, you also need the ECU and wire it.

If you can do all this yourself, and have the money to support it, I would probably do the Bisi cam.
But it would require getting a tuning system and some dyno time.
Also, remember if your going turbo later, you might have to replace the cam again, depending on its specs.

I don't know anything about your setup, but if you have a stock intake and exhaust manifold,
they would NEED to be replaced to take advantage of the cam.
The design of those items are horrible on this engine, power wise.
You would also need some 240cc injectors (from an Y8 or just about any MPFI Honda except the D16Y7 and Y5 I think).

So, you see that once the ball starts rolling, it quickly builds up.
I have written this based on my limited experience, and without any knowledge of you who started the thread.
You may already know all of this, but I hope it will help you decide.

You think Bisi builds nonvtec cause he doesnt know what he's doing? No! He knows better then anyone else. I would go bisimoto!

im gona tune with the greddy ultimate e-manage because its smog legal here in california. i cant go swap to obd-1 and tune with crome after i do a cam and a turbo because the car wouldn't run with the basic y7 ecu. so in the end the e-manage unit is all i can really do.

But the Y7 and Y8 use the same valves.....

main difference is the combustion chamber volume, Y7 = open chamber, Y8 = closed chamber.

Im getting my Y7 with the Bisi level 3 cam tuned next week. Hopefully i should be bale to put some numbers up. Maybe that will give you a rough idea about potential of the stage 2...
