sohc vtec is as noticable as those electric superchargers :-\

Re: vtec
 

the z6 is still the best flowing head that honda made for sohc, better than the a6. someone whos done alot of research like abaz whould confirm this.

Re: vtec
 

No, it's not. A6 is better, SOHC ZC is about the equivilant. Ask J. Davis about the Z6 his friend swapped in place of an A6 and lost power all over the map.

Re: vtec
 

great thread! i am going with a a6 head on a z6 block. with all the reading ive done this seems to be the best bet. non vtec that is

Re: vtec
 

Yay for low compression setups!

Re: vtec
 

and then im goona boost it. im giving up on the N/A .

Re: vtec
 

either way youre gonna be fine. id be more worried about getting it tunned right than the heads.thats were youre gonna make your power, tunning. and yes theyre low compression which is good for boosting.

Stock Z6 outflows ported Y8.

Now, Bisi would tell you that a larger diameter curved pipe can be made to flow nearly identical to a smaller diameter straight pipe. However, getting someone who knows how to hog the hell out of Y8 ports to mimick this... good luck, guys.

A6 outflows Z6 right up until the smaller intake valves acts as a restriction. Then you upgrade the valves and ---- VTEC. Ask MAX_CFM about this, Minor, I'd trust him on the LS-->ZC valve interchange being subject to bore shrouding, to boot. :P

By bringing in OMG VTEC a little earlier on Atlee's Z6, we were able to get ~4 psi more boost a thousand or so rpms earlier. This is so important, because the pristine super clean low mileage Z6 made noticeably less power than his high mileage ZC that kept shitting #1 rod bearings. This is because OMG VTEC sucks.
