Steve, I am flattered. I must say it is great to be a part of such a amazing community. As for my car I had every intention of using 180 deg exhausts to my turbos but it did not work out that way. My system has headers that come up and over the rear inner fenders but are only 90 deg. The car is being built for open road racing so I have no concerns with lag and such. If you were to fabricate a 180 deg turbo system I would highly recommend using tangential style turbine housings to make it worthwhile and ball bearing turbos to minimize friction. The only way to help offset the cooling effects that Jon mentioned would be to use the thinnest wall stainless you can find and have secondary supports to hold the turbos weight. Thinner wall tubing will actually give up less heat than a thicker wall and stainless has the best high heat characteristics. You could also have them ceramic coated. If I am not mistaken there was an article about a twin turbo 180 deg system in one of the most recent PI issues. I say go for it. With a goal of 150 hp gain it is obvious that you are not going for all out HP therefore performace is not as much of an issue. A 180 deg twin turbo system has to be one of the most amazing looking systems out there. Take Care and good luck with your project.

I plan on going ahead with two t3/t4 turbos, so I will let everyone know how things work out.
My cr is 9.85, which I have been told by several venders will be ok.
When I put the engine on the dyno I won't be able to have the turbo system on because it will interfear with the dyno itself.
Thank you for all the good information.
