It's been a while since I've made a topic, but I figured I'd share my new setup. Hardware-wise I'm running a flipped t2 manifold with a t3 flange welded on, 550cc injectors, z32 mafs, and I'm pretty sure I'll be running a Precision 5457 with a .48 A/R. I originally planned on running a Holset hx30, but after doing some research I realized that it's too small for my power goals. I'll post some detailed pictures of the manifold when I get it back from my friend who is doing all the welding, but it looks like the CX Racing top mount t3 manifold.
For everyone that knows turbo sizes, do you think the 5457 in a .48 a/r is a good choice? It seems comparable to the Garrett Super 60, but Precision doesn't release compressor maps for their turbos so I can't tell where the KA would be on the map. It has a 54mm compressor wheel and a 57mm turbine wheel, pretty close to the Super 60 but it might spool sooner due to the billet wheel and Precision's new wheel design.
Here's a picture of it with the Holset on there, I was pretty close to having it running before coming across a compressor map for the hx30.
