that engine can be turbo'd and forged. (I have a log manifold over here actually)
You would need to turn into 7agte
Forged 7afe bottom end, balanced crank,forged rods,forged pistons. 4age head cams for turbo etc
And run a turbo manifold with a standalon ecu like the fcon v or power fc.
It will fit in the glanza but one engine mount needs modifying i think.
Would be ultrafast and good for 400-450 very easily and still be realiable as well as a load of torque.
