Turbo vs Na intake manifold
I have been searching around. I have not found any info on this subject. Is there any difference between the the NA/turbo intake manifolds?

no difference

Unless you are talking k-jet intake, but for B230 LH there is no difference.

Thank you.

As stated, the B230 FI manifolds are the same, turbo or NA.

There can be minor differences though, but they're this; EGR port, CSI port. Some manifolds have both, some have none, some have one or the other. All depends on which variant of LH and which emissions package you have.

How much of a difference does the na b21 intake make a difference in the b21ft?

I don't think anyone has done a back to back dyno test, but the N/A intake strictly from a design standpoint is WAY better than the stock B21FT manifold, and even better than the B230 manifold (longer equal length runners, an actual plenum).

It's an easy modification, and definitely worthwhile if you've still got that craptastic pancake B21FT intake.
