Is there any advantage over all of this instead of just buying a GR Yaris? 
Apart from cost I'm guessing
Is that one 4WD? 

The car was acquired already built and never run in anger, AP4 rely on a whole lot of control/compliant chassis items to meet regulations. So the initial investment and specialist fabrication was already completed on that car, they look like production shells but they're not.

While we're discussing other cars.
A guy in Hamilton has recently had his turbo 1NZ tuned up. 
289hp at the wheels at 18psi. Has an 8700rpm limiter. 
So easily 200hp per litre from turbo setup (at engine) 

He's said it's a bit too laggy for his liking though, so is going to try a different turbo. 
Hopefully manages to keep most of that top end power on the next setup.

Haha nah not from 1300, maybe lucky to get close with 1500cc! 

I think 264 deg cams being the biggest available for a 1NZ will become a limiting factor. 

BMW S1000RR is pretty wild, 1 litre engine makes 200hp from factory. Up to 14,000rpm. So good! 

I've seen a few people swap these motors into small cars overseas but they seem a bit spendy/unobtainable here.

If could harness @Roman  intake mods.   In a perfect world the same 18psi would be about 316hp or 27hp more.    not really apples to apples  / dyno to dyno.   but maybe a better comparison than most, considering both have a cork in the exhuast
