Thats awesome man, that car is amazing. You must be getting god almighty horrible fuel mileage running that E85 (i know fuel economy doesnt matter lol).
I have a really dumb noobtastic sorta semi unrelated technical question though. I was re-looking through the thread and when I looked at the first pictures I became confused. On the RB, what cylinders move together? I know on a KA its 1&4 and 2&3. The pistons look all over the place in your pictures.

I want to start out by thanking the guys at Abel Racing in Midwest City, OK (Specifically Erwin, who goes by Efeezi on the various online forums.) You guys have been a pleasure to work with, and your knowledge of all things Nissan is amazing.
It's been six months since the 240SX encountered bearing damage, which led to a full motor rebuild.
This downtime gave me the opportunity to rethink the current engine configuration, etc. While I was happy with the power of the Borg Warner 74mm (1.10 A/R) turbo with 9" cover, the spool characteristics weren't ideal for a street car IMO, and I wanted something that could make similar power, while providing a larger powerband.
After consulting Borg Warner, they recommended their 72mm (.90 A/R) ETT Turbo with their new 10" Race Cover, which has been dyno proven to make up to 60whp over their standard 9" cover.
The motor was rebuilt with an N1 Crank, JE Pistons, and Eagle Rods. Head was left untouched from the previous setup, complete with Tomei Hardware and 260/260 Poncams.
The car now sports the new Tial 50mm Q BOV, which sounds amazing, to go along with the Tial 60mm wastegate, and I'll have some dyno videos to post this weekend, pending all goes as planned.
Here's some sneak peaks from what's to come. Forgive the dust, it's been tucked away in the corner of the shop for several months awaiting parts.
UPDATE:
The car was completed today, and I’m very pleased with the finished product. The plan is to dyno tune the car tomorrow, and I’ll upload the graphs as soon as we finish. The car sounds beastly in person, I wish you all could see it in person.
Special thanks again to corporate sponsors: BF Goodrich Tires, Tial Motorsports, Borg Warner, Abel Racing, Je Pistons, Eagle Rods, Tomei USA, and many others along the way for your help with the vehicle.
As promised, here is the debut video of the new setup:

Update:
Had the car shot yesterday by two automotive photographers here in Oklahoma City. I’ll let you be the judge of the new setup; these really do the car justice. Hope you enjoy!
