Millenia vs ZE intake manifolds

I did use the search button but I didn't see the answer to my question.
Iv'e got a straight neck ze with a millenia intake.
Would a curved neck ZE manifold be better than my millenia intake?
Does any body know torque or horsepower differences?

I don't think anyone really knows. Word is the curved-neck flows better, but the downfall is that you can't get an ECU for the curve-neck IM

hold on did I miss something? I thought that the Millenia IM = curve neck IM!! I thought they were identical!!

Are there 2 types of curve neck??

Ya, the Millenia curved-neck uses the square runners as well (part reason why it's rated for 170hp and not 164hp). It's basically the same IM for curved-neck DE's as curved-neck ZE's

Good eye Mooneggs. I based my replay on the topic. I missed the part about it being a Millenia ZE IM, I though he was talking about a straight-neck ZE vs Curved-neck. Man, I'm spending too much time in front of a computer, been mis-reading alot of stuff on here this week :S

But ya, as far as we can tell, there's no difference between a Millenia DE or Eunos ZE IM

Hehe, technically there is if you count the K8 IM

since the plenums are different the straight neck will make a higher peak horsepower, It won';t be by much and its got most of its power in te higher end of the powerband. The curveneck makes its power all throughout. So for a daily driver its best to get the curve so you got some midrange power and torque.

Also the curved neck flows better!
