i took the power steering pump off and covered it with a piece of 3/16 plate steel i cut to match the flange on the pump .used rtv for a gasket and bolted it on .there is almost no oil pressure here ,it just bleeds out enough to lube the pump bearing so the rtv(hitemp black) works well.

the hole in the middle of the plate is threaded so i can bolt this header flange stub to start the exhaust system .

i also got the blowoff valve i am going to use .in the sumitt website it is listed as a vortech part .but it is a bosch part .this was the cheapest blow off valve i could find .when the pressure gets to high when you snap the throttle shut ,this valve will open and the pressure will get recirculated back to the pre turbo intake tube .the pressure that it blows off at seems to be controlled by a vacuum line that goes in to the top of the valve .not sure yet how i will hook that up .

I know your doing turbo now, but if anyone else needs an exhaust header this looks like a good replacement style

It looks like it comes straight down, how far it goes towards the trunk maybe a problem.

Watch that ICM. Those things are sensative little buggers. There's a recall on the 03 and older units. They like to short out on ya and leave you stranded. Bad ground in several places on them. Might be why GM uses a dist on thier turbo race engine.

tonight i had a magor setback on my turbo project .the seals on my brand new tubocharger are leaking oil ! i dont know if they were bad from the start or if i had a blockage on my return line .it is supposedly under warranty so i will wait and see what the dealer says .so now the turbo is off again and work is halted .i thought buying a new turbo would avoid these problems.
