M20 short runner intake manifolds?

[rThor432]

rThor--You have that backwards; the first picture is a 325i manifold and the second picture a 320i/323i mani

Whoops! Missed that mix-up, thanks.

Is there any benefit to using the 323 mani for FI applications?

The shorter runners would help the top end but are the runners any wider?

Has anyone ever heard of someone using a 323 intake manifold?

I have. Mitch M ran one on his 2.7i for a while. I havent put mine on yet.

The 323i manifold has constant-sized runners whereas the 325i manifold is tapered. If I remember correctly.

I was behind that beast about a Year or so ago. Sounded awesome. Gorgeous color too

It's the perfect example of an early model E30. Everything is well done and extremely tasteful.

Would there be enough interest in some short runner manifolds?

I've been thinking about making up a few of them in my spare time.

I've been working on a short runner intake for a N/A engine. I'll post up some pic's when I can get to it.

323i/320i has smaller diameter throttle body.
