RedVTI the mounting bracket your talking about doing wont work. Spoken to my welder and its actually not the stress of the turbo hanging of the manifold. its actually the size of the metal where all four ram horn pipes meet in the middle. The thickness is only 1.5mm where it should be 3.0mm. The ram horn pipes are 2mm and ive never had problems with them. the problems occur toward the bottom near the turbo flange either in the welding or in the actual metal. I made a chassis reenforcement in the beginning and it didnt make any difference. the best thing to do will be to buy a new 4 to 1 exhaust pipe (same as the one on there atm) but in 3.0mm cut the old turbo flange plate of the old one weld it onto the new one and weld the new 4 to 1 pipe onto the meeting joint of all four pipes. Soo pretty much just replace the 4 into 1 pipe from the 1.5mm to the 3mm. also where the waste gate comes out of the manifold that little pipe will need to be reinforced as the hang weight of the Gate will cause the 1.5mm pipe to crack.

Also make sure you dont use the Gaskets they give you...they only lasted me bout 3 months.

But honestly guys i don't know how much PSI these kits can take...i was only running 7psi and i had problems, my internals could run up to 24psi but i never took it that far because i was afraid of other things braking on the turbo kit..
