I think this will fit without a spacer... any thoughts? It would make you turbo setup easier.

About the only disadvantage I can see is that you lose some exhaust gas energy before it hits the turbine. Advantages are that you get less heat soak on the intake manifold and shorter intercooler plumbing.

well, for what it's worth.. this manifold is what forced me to have to open up the wastegate more than ever. it pushes the turbo to insane levels. i was hitting 20psi without aboost controller! AHHHHHHH!!!! also, it spools faster than with the stock manifold. and yes, my intake temps are very low, especially with the heat wrap and intercooler piping is at a minimum.
oh and..... air filters? what are those!
there are more pics on my cardomain page

One of the main advantages is that it would fit a first gen... I should hve clarified that the header is pictured on a 4 port but my application would be a 6 port. It appears that there is plenty of room for clearance.

trust me, i didn't want 20 psi at all. i just had no control. i was just giving an example of what a tubular header will do. when i was running the stock cast manifold i could easily stay at 6psi with a barely ported wastegate. if you look on my page, you'll see what i had to do to get it down to a minimum of 12psi with this header 
and altho the stock turbo does lose efficiency around 14psi i did notice a niiice difference stepping up to 16. i'll have a video up hopefully tonight of me racing my friends half-bridge TII.

Well I would rather go tubular to start out with and besides this setup allows for an external wastegate... therefore greatly reduced chance of boost creep!!

Here is the description...
This is a custom built turbo exhaust manifold for a 13b rotary engine. It was designed to fit in a 1st. gen chassis but should fit in cars where the engine is mounted by the front cover. It is made of 2" diameter 1/8" thick stainless steel and fully TIG welded. Flange is for a T4 style turbine. The wastegate flange is a 2" v-band connection. This was used with a Turbonetics NewGen wastegate. No wastegate is included. Check my other auctions for the wastegate. This was only used for a few hours.
