After watching a video about an S2000 with ITBs, I'm convinced I want this for my 13b Cosmo...when I get it.



Anyways, I just wanted some information about this and rotaries.



Maybe someone can enlighten me?



Right click, save as.

explain to me why? https://www.nopistons.com/forums/pub...1047683561.gif

There are quite a few places that offer IDA and or DCOE manifolds for 13B's. The only off the shelf manifolds that I have seen for the 13B-RE have been IDA style, which use IDA style throttle boddies that can be purchased from quite a few places. http://www.twminduction.com is one place to find the TB's, you can try ebay for the manifolds.

Here's where that guy got his.

Generally speaking more useful on laaaarge ported N/A motors, but have been used sucessfully on really high power turbo engine aswell..

Only when the std. inlet manifold becomes a restriction.



Having said that this will be one of the next mods to my car.. mainly because i'd like to play around with different runner lengths since my engine is now got a reasonable sized street port https://www.nopistons.com/forums/pub...IR#>/smile.png





I've also seen, over here in Oz, people use individual throttle bodies, Ie one per inlet runner, 4 throttle bodies in total all feeding a different port runner. A very good idea. imho, since you can have longer/shorter runners depending on which runner has more timming. I think all the top running cars in improved production here use this style setup(on ~300hp bridgeport engines that don't cut into the rotor housing at all!!)

Would the use of 1 TB for each intake port increase torque?

Yes, if you had the right runner lengths and cross sections chosen.... https://www.nopistons.com/forums/pub...IR#>/smile.png



It's all a trade off really when it comes to inlet runner choosing though, you will add torque somewhere, just depends where in the rev range you want the torque to be added to really.
