Manifold is test fitted in all chassis it came in (e46, e39, e60, e90 and etc) with big turbines like the Holset hx35, Garett gt35 and Borg sx-e366. Test fitting has been done to the most popular swaps as the Nissan Patrol and Toyota Land Cruiser and etc. Flow and port size is optimized for high hp with superior spool time. 3 bolt wastegate flange corresponding to a 48mm wastegate surface area. All manifolds will come with a gasket, block flange if an internal wastegate turbo is used and a flange with a hole ready for 50x2 tube/bend to be welded on. There is available Wastegate Relocation Addon which will reduce interference issues in smaller chassis like the e30, and will leave the exhaust gasses divided until the wastegate itself. Please note that warranty claims for cracked manifolds will not be honoured with the lack of a flexible coupling on your downpipe. Using a turbo support/brace is advised on heavy turbochargers like the Holsett Hx35/Hx40.
