People, get this through your head. 12.5 CR is NOT the limiting factor in boosting an engine. I swear to God I am fucking fed up of the constant whinging. Fricking hell man. It's a tuner car. It will be modified, tweaked, and tuned. The only achillies heel MAY be the ECU. We however don't know anything about that yet, so no point is being a damned downer. I wish I could permaban every moron who starts a useless, idiotic thread
**gets off soap box** [/rant]

A set of after market pistion+rod. But those are just over my budget limit.
I'm considering an used BMW M3 E90/92 now... which is... shame..  |
Milling the block will raise compression. If you can afford a used M3, then I'm sure you can afford a used cayman. If you like boost so much, why not buy a used 335 coupe and boost to your hearts content?

Most if not all Toyota engines since the late 90s run forged cranks. If we are lucky, we might get rods and pistons too, but don't count out what could be achieved with stock pieces, forged or not.

Yes. He did. In fact, he probably should have been a bigger **** about it.

And I am still betting a few years down the road there will be an engine update. I'm not getting a car anytime soon, still in college, but if I'm right I probably will go for said updated FT, well if nothing better comes out.

I'm betting that this engine is purposely choked from the factory. The GR and UR engines pick up anywhere from 20-30hp with basic bolt-ons. Granted, this doesn't have their displacement, but I'm sure 220hp is within the realm of possibility without that much effort.

Talking and actually trying are two different things.

Stock engines are usually heavily choked. It doesn't matter that it is the highest N/A output, they have to meet strict emissions and there is always room for improvement. The question remains how much. But I am optimistic that there is room just in a 93 octane tune.

This.

And definitely this. It is a lack of development simply, no design constraint whatsoever. In fact, boxer engines ought to rev higher and harder than your run of the mill inline 4.

Could always go for a shot of NAWZ too just for the lols.
But seriously, intake (maybe manifold too...), exhaust and ECU will be the limiters, they usually are on modern cars.

I'm not even sure you'd need an ecu to achieve this. Certainly would be helpful though.
