Mon, 03 March 2003 12:43 Ok, here is my theory on the subject, Use steampipe that is as close as you can find to the exhaust ports of your engine (inner circumperence of pipe close to the inner circumference of your exhaust ports in the case that they are not perfectly circular) but make sure you chose the closest size smaller than your ports. according to an idea i have discussed with somebody, this will aid turbo spool by increasing the exhaust gas velocity (maybeye, can't hurt) Get a plate laser cut to fit your exhaust ports/exhaust studs etc flare out the ends of the pipe to the size of your exhaust ports/new laser cut flange. make your manifold, enuring that the pipes leave the flange as straight as possible, don't make any sudden bends, make the pipes roughly the same length and come back together all pointing straight in the same direction. Get another flange cut (this one coudl be cut with oxy or whatever and cleaned up, not so dimensionally important as the exhaust manifold flange) for the turbo to bolt to, weld a collector pipe from all 4 primary pipes and then weld the turbo flange to the end of this. If you are going to be using a twin entry turbine, pair cylinders one and two to both enter one "hole" and cylinders 2 and 4 to enter the other hole. there you go, hope this is helpful, if i was going to make a turbo manifold, this is almost exactly what i would do. will [Report message to a moderator]
