I have heard that the original motorcycle mounting is the same bolt spacing as an IDF? I mate has used a set of Suzuki Hyabusa bodies on his Alfa 2.0ltr powered sports car with great success.

could be...it seems there is a "standard" 90mm bore to bore spacing for a lot of the throttle bodies

progress today...I decided no welding or brazing and no adapter plate....

I simply machined the top of the manifold and will attach the throttle body directly to it with a hose and clamp...this is a similar method to how the t/bs are held on on the motorcycle

the hose clamp is a special clamp which is used in turbocharger applications, it has a true 360° hold on the hose....it's on there pretty darn tight, I'll still add a bracket to align each t/b to on another on a common manifold.

These are what I had, didn't know there are different options for the manifolds...oh yea, the cut is offset from the inlet on purpose, this matches the throttle body and allows the fuel injector to spray directly at the intake valve like the factory setup....it's a little further away, but I think it'll be fine...

Hey Mike - is your CNC mill up and running now or are you still just jogging around with the keyboard?

Glad to see this project coming back to life !

Just out of curiosity, what is that little hole in the outer side of the manifold ?

Mike,

since the TB's are not rigid mounted, how do you plan to do a linkage between them? seems it will be pretty hard to sync if they are free to move up and down a little.....

I think he's going to add a bracket. Plus he's using a hose but it's so short there's only one clamp so I can see it being pretty tight. Hey Mike, is there enough material on the TB and manifold to machine it down for a V-band clamp? Then you wouldn't need to use the short hose at all.

I had the demo version of Bobcad - that thing is a bear to learn. More like a learning cliff than curve.

looked into it....I already bought the hose ($16 per ft), and don't want to spend too much time and effort on these...

here is them mounted on one side of the motor....

I screwed up, these manifolds are for 2.0 3-bolt heads...my motor is a 1.8 with 4-bolt heads, anyone want to buy these?? (IMG:style_emoticons/default/smile.gif)

(2.0 head in picture is thrashed beyond repair and for mock up use)
