I'm making a batch of manifolds that are almost complete. You can see an example on Chris May's website
http://www.executivecleancar.com/240 .
I have revised the placement of the T3 flange to place the turbo farther away from the master cylinder so it's not exactly like the Revhard anymore. The design of the runners is just like the one shown on Chris' site though so you won't tell much difference from looking at it.
Anyway i still have a couple that aren't spoken for so if you're interrested just e-mail me and I can give you more details.
Chris and a couple other guys have been running these manifolds for at least 6 months pretty hard with no problems.
