any one know if the rew throttle body will bolt up to the 13b re manifold, not worried aboud idle control valve it will be removed, any help appreciated,

 

I'm also interested. But if I remember correctly I have read that it bolt right up.

 

Yeah, it'll work...just got to seal up the bottom portion of the RE manifold that the TB does not cover. I'm not sure if it's worth it, people have been making huge power with the REW manifold and TB....just turn up the boost

 

Go with the 20B TB, it will seal up with no problems and has your idle control valve.

 

It will fit, but there you do need to seal up the bottem like 88fc3sw/HX83 said. I made a spacer out of aluminium. You could weld the bottem of the cosmo intake up, that is if you have access to the proper welder. I had the fd tb and the aluminium laying around.

 

but fd tb's are $50-100, 20b tb's are hard to find.

i used one on a cosmo manifold one time. no idle control (it was a microtech), just epoxied the back side and it was good to go.

 

thanks for the help guys
