We now have everything finished with the motor minus the installation of the new 24x12x4 intercooler that arrived today.
I want to thanks Matchless Performance (Addison, TX) for the fabrication of the downpipe, which came out better than I would have ever imagined. The welds are amazing, and extremely clean.
Here are the latest images:

While I still have the interior to finish off, here are the completed exterior shots.
This 240SX has been four years in the making, with 30 corporate sponsors on the stage II build.
I want to give a special thanks to Andy Vaughn @ Southern Imports, and Chris Hamilton (tuner) for their work on the vehicle.

Sorry about the delay on posting up dyno numbers, but I have crazy busy and the car has sat for the past few weeks.
I have not added C16 yet, but I did tune the car for E85 Pump Gas. Right now, E85 (106 Octane) is $2.18/gallon at the pump here in Texas, so it's a no-brainer.
As you can see at 25 PSI, the car made 629/490.
I'm decently happy, but will be upgrading probably to a GT42R, as I really want to break 700whp on pump gas.
Also, took the car to be weighed, and I was pleasantly suprised.
With full interior minus a passenger seat, and 3/4 tank of gas, the car came out to 2890 lbs.
Look for a larger turbo, and big power numbers over the next few weeks!

There is not a question that am jealous of your car, that thing is AMAZING I don’t even know where to start. The only thing I’m more jealous of is your knowledge, I’m hoping to get my 240 this weekend but I will still be lacking the knowledge of all the little parts. But there is always time to keep learning 
LOVE the car and good luck with the rest of it

yea a 240 is a simple car very good for learning.
also man been looking at this thread since your first post damn that **** is hot. btw with your build i think you can run a reliable 800whp with the right tune
we have all seen them japanese guys with 1000hp on stock internalsof the RB26, most likely not reliable but if they can do it you can do it easy!
