I am interested in that manifold but the price tag scares me away when I can just build something to work. Not to mention I like to weld and stuff. Plans are right now to do use a split flange T4 compressor housing with the header being equal length runners combining cylinders 1,2,3 and cylinders 4,5,6.

Right now Im leaning towards a GT4088R with a .95A/R. Taking a poll most people who are pushing these 6's and other higher reving yet lower displacement ones (supras) seem to be running this turbo and like it. Plus with my ruff calculations it should work real well and have me right in its most efficient range. The only thing Im worried about is the A/R ratio causing the engine to be a dog down low and having a fast yet very powerful power band.

what do yall think?
