If you are going to try and use that exhaust manifold, you are in for alot of trouble. You need a 24v manifold. And get rid of that v-band on the 474 and weld a 90 right on to the comp. housing. Gives you a ton more room. I know of more than 1 person that spent hours trying to get a CR manifold to work only to give up and start with a 24v manifold.
Sinner - I'm not going to use that manifold, I was only using it for mock up of the lower turbo to make sure it would clear a manifold. I have another manifold in mind and it should be here in a few days. I tried the Gen 2 manifold and I didn't like the way it fit so I'm trying something new. Hopefully it will work and I will be posting some pics soon. Good idea on welding a 90 degree on that turbo and I may have to do something like that. I will see in a few days. As far as Your engine goes that looks bad ass. If mine turns out half as nice as yours I will be happy.
