n1 throttle body ordered from Gspec today.
As soon as I get it, will be off to a local metalworker to take a look at...

i always thought the general rule was to make the plenum roughly the same size as the engine displacement .

reading a little further indicates that my initial estimate was a bit small, so i will be heading closer to the 2L volume, most honda vtec intakes are quite small in plenum size, so may take a leaf out of that book.

a smaller plenum also makes it easier to squeeze into the engine bay

has anyone considered the possibilities of gains by using the 20v intake mani over the 1st gen sr20vvl manifold? is it better designed?

won't match up very easily and you'll need new injectors
the 20v(VET) was the only VE motor truely designed to be 2.0L

precisely, so what about the specs for that manifold? eg plenum volume, runner length, taper (if any?)... could those specs be helpful in our design?

As it relates to the secondaries from sr20venofreak, I have some figures to post.

I am happy.

Just waiting on my dyno charts to be emailed to me.

Thanks again man.

Peace
