the S300 will sit on the efficiency range from 3K till redline AND it'll give you room to grow for the after party that happens around 30psi. I'll get the datalog of an S300 83/75 Supra i did, dude wanted response and we were seeing 18psi in under 3400rpm if memory serves me right. we are adding cams and springs to the car right now so we can strap it on the dyno to get some actual numbers but it's a riot right now on the basemap & 91. since you're 3.3L i think you'll have a ton of fun with the S362SX-E just something to think about.

You're right. I went back through and corrected the S200SXE values and I noticed that the 2000rpm point was deep into surge. I'm not too concerned with off into choke, but it does look like the 61.4mm would be damn close in response. Thanks for the input, I'll be moving up!

The firing order of Nissan V6's are all 1, 2, 3, 4, 5, 6, so you literally just pair the runners together by bank and run them into each side of the turbine housing. Doesn't get much easier!
This is my friend Mike's. He has a divided T3 GT3582R. My setup will be similar.
