yeah that would work and just get a worked head while you are at...might as well open the ex side for less back pressure.

I am working on getting custom turbo cams now and will update appropriately.

no updates...head is out of state for more R&D. Was going to get Kelford to make cams but ran into some issues with the head so still working on it. Dont hold your breath since my CAPT. REV project is being postponed and FS. But the head stays with me since still doing R&D on it.

But we pretty much know what needs to be done...just need the right cam to top it off.

Do you have a flow chart on the stock VE head? I would like to see it if you have it. I showed one of the guys at the shop your head flow results and he won't believe it. He said you can't get a head to flow that much haha. But I asked him about some other engines and he said he has seen the k20 heads flow 280cfm stock.

But he did say that a 2.0L engine with that head would make around 400hp NA. That would be insane. It sucks your project is being put on hold.

Here is the stocker. My final graph had been questioned and I am not pissy over it. I had it reflowed on another bench and it read lower, 350, which is not to bad at all. That is why I have no cams made for it since the cam manufacturer said thay did not believe what it put out...so no cams for now.

So since now it is at 350, difference seat angles will be utilized and probably a bit more port work which I think will garner at least 30 more CFMs.

The last flow of 350CFMs is not set in stone, I dont really care for flow numbers per se it since all I need to know that this head flows progressively thru the lift range and it does.

ENJOY!!!


^So these are before and after #'s I'm guessing? I know this guy does not post on here anymore, but do we have some more before and after bench flow results from the VE guys? N/A and Boost.

^I'm trying to see what all I need to do to get my VE head to match my 2.3L N/A setup. I'll be running N1 cams with BC s/r's, a 4-2-1 triple stepped header, and a custom intake manifold with 6-6.5" runners with 52mm v-stacks. Pretty simple setup up top for the most part.
