There's a reason why the 20V head is superior to the regular 20ve and it isn't because it has larger ports.

i seeee

take a look at b series honda motors and what those boys do with a stock head with good cams a stock intake mani and a high compression 2 liter bottom end.
the ve head flows just as good if not better then a b series head and those honda guys make alot with stock heads and a good bottom.

the bottle neck really is compression, cams and a header.

hmm.... i can tell you that the intakemanifold on a bseries is not designed the same as a sr16/20ve.... the head, even though it flows well has flaws and not all are equal.

For all you know he could have already cleaned up the head and is having a custom IM or ITB's made and a custom 4-1 header.

Edit: I had this written out but didn't click the post button, I got busy. Didn't know that he already responded

if he had an IM he would have said it. I do know that if you are going N/A there aren't any cams that are going to do much on a stock head or even a head with port work. I also know that a stock 20ve bottom end is completely fine for the limitations of every other N/A performance part he wants to add.

people make motor builds more complicated than they have to be buy a 20ve and add the bolt-ons call it a day...nice and reliable. If you want to throw money at something the bottom end (stock bore) isn't where you need to put your energy.

My opinion of course

I don't care if someone can make more power then me. Or is more reliable. And, I DO NOT care if you think 12.5:1 is not high compression.

Let's try to get back to the BLOCK.

correction there is, but everything takes time

interesting...it will take MUCH more than just porting a manifold to get results. probably more tha some are willing to pay for.
