Marlin Crawler Lemon Racer would be pretty cool ;D
Regarding 140-150 HP, I plan on running a
MicroSquirt stand-alone ECU that retains all factory sensors....I know you guys are familiar with MegaSquirt, well this is the smaller version which is so small we can fit it into the stock 4A-GE Toyota ECU housing:
Look how small it is!

I can easily stash that into this, using all factory Toyota plugs and wiring:

And just yesterday I stopped by Precision Auto Customs, right down the street from Marlin Crawler, owned by my very good friend Justin who was trained by Shelby and has his own Dyno Jet, and he has lots of experience with Mega and MicroSquirt and has all the software to do all the dyno tuning.
I am immediately going to do this with my 4A-GZE for my MR2 so everything will look stock and yet it will be fully dyno-tuned, so we could do this for the FX16 as well. I really doubt the judges have time to open up ECU boxes, and even if they did we could mount it upside down or put Toyota stickers on it, or put security paint on the screws so it looks like it has never been opened, whatever.
Then we could get it tuned on the dyno. We can set the rev limit, the idle speed, anything. So for the brick-throttle test we could limit the rpm to 7,400 or so (I'm sure they'll be looking at the tach) and for the race we can set it to 8,000 rpm.
Whatta ya think?
