might want to check the emissions laws so you can plan accordingly. in Ca without a California air resources board approved sticker any modification to the engine or control system is illegal. basically out here it is all out or stock.

Nice work !!
only wish you had done this later (once all up and running) so we could see the increase in HP and flow compaired to the stock one.
but bloody nice work !!

Niiiice. I'd be too squeamish to trust my own work on thse kinds of things! One of my friends custom fabbed an entire turbo system for his Benz 190E 2.6 along the lines of what you do. Keep it up!

For others who are reading, SDS-EFI has a writeup on how to build an intake and they use a 2nd gen as an example.

Longer runners make power lower due to higher velocity but choke higher up, shorter runners make power higher up due to less restriction.

Aaron, I must say this is just the next thing in a growing list of what I've come to expect from you. Your attention to detail and persistance in producing only the highest quality workmanship is not only a continuous inspiration but an increasing respect.
I look forward to seeing what you come up with next, and certainly to working on more automotive projects with you in future.
Do it once. Do it right. Or do it over.
My hat's off to you man.

Where did you get the flange? I was planing on making a LIM with a FD UIM, I have a friend that is a machinest. How do you feel about the FD UIM paired with a custom LIM for the 13b 4prt motor? Would it be worth wile to make a UIM as well? Consider the TII UIM flows much betor then the 13b 6prt motor.

Not quite right. Runner length does affect flow (longer = more restriction), but for a given airflow it doesn't affect velocity, only cross-sectional area does. Longer runners make more power at lower rpm because the longer the runners are the lower the resonant tuning point occurs. Shorter runners make more power at higher rpm because the resonant tuning point occurs at higher rpm. Skinny runners make good low rpm power because the higher velocity results in more swirl in the chamber for better air/fuel mixing and more efficient combustion, but like you said costs power at high rpm due to the restriction.

I do have to ask, why did you taper down the primary runners mid way through? Why didn't you just use the smaller size all the way into the plenum chamber? The lack of transition would actually have let it flow better and it would have been less work.

The NA manifold has to make several 180 degree bends during its process. Where the TII only makes one 120degree bend or so. Even though the runners are the same diameter the overall length and angles are less on the TII.
My purpose for the LIM is to remove all them block offs make it look much bettor is all it was for. As well you could make the runners a tad larger. The UIM was a tossup my original plan was to use the FD UIM for 1 it dose not have the TMIC holes on it, so the FD UIM looks bettor. I have not seen any performance increases that are stated outside of a few butts that say moderately bettor. I am going a lot of looks and would like performance with it but not willing to sacrifice performance for looks.
