Today I had a measuring up session in engine bay to work out how im gonna fit my monster efr 9174, its a big girl!! I came to conclusion I will low mount it on a psr log manifold, cut off manifolds t3 flange and get a t4 divided flange welded on in a slightly more upright position, only about 10mm more upright to get clearance between bottom of turbine housing and engine mount heatsheild. I looked at a Artec investment cast 347 stainless manifold, very nice piece of kit, but its over 2k and 4inch dump would be a very tight squeeze, and have to go down real steep and the water pipes by firewall would probably need modifying. And heat would be a issue I think. I will have to bore 2 holes in the twin scroll housing just after turbine inlet and run 2 pipes into 1 and then into w gate. Id rather not drill into housing if I could help it but I would have to j pipe it and higher mount turbo and run gate off j pipe.
