Compare the bolt pattern for this roadrace header from Racing Beat with the turbo manifold I linked earlier in the thread. They look to be the same.

RB header

If I'm correct the manifold bolt pattern for the turbo II and N/A are the same, so you should be able to use the same manifold with some minor adjustments so that it will fit around the intake manifold. I could be wrong, so if some of the other N/A guys could chime in and confirm or deny this I would appreciate it.

the na manifold sticks out a lot further than the t2. if you compare the two the t2 hugs the block so theres more room for a turbo.

i tried an hks iron fc manifold with an na intake and it almost fits, it would need a spacer or 2 made, but it could work.

They are the same. I made my manifold for my T2 using the header flange from RB. I also purchsed an NA gasket to confirm that it would work, and it does.

thanks guys i really appreciate all the input. i am new to not only rotarys but forced induction also. so far i have an hks intake, i did the throttle body mod and had BDC finish modding the throttle body by taking out the pressure drop points etc. i have recently purchased an HKS Super AFR for fuel management. I am thinking about buying a rebuild kit from Atkins Rotary and rebuilding before i boost
