After looking at some pictures of some popular custom 13B upper intake manifolds, I thought about maybe making one for my 20b. Then I thought, I wonder if it would be of benefit to split the pipe between the throttle body and plenum, to ensure equal distribution of air to all the rotor, like how a supra engine's intake manifold is designed.

Too see what I mean, check this out: http://www.geocities.com/bported/temp.html

What do you guys thinks? Good idea? Not necessary? Can't hurt to give it a try?

 

how about cutting the plenum off and putting individual t bodies right on the runners?

j9fd3s, That would make one bad *** NA 20B intake!

Anyone else with some input? I need to get some intake manifold design books or websites, does anyone know of some?

 

heh. I'm not interested in a custom intake manifold, but I would be interested in your stock one, as mine arrived damaged.

 

email ralphh@dgdg.com he has a new upper
