and yes you make an interesting point about long term longevity, I suspect most folks whack on a FI kit and go for broke without thinking just how long the stock bottom end will last
I'd hope that Cosworth have considered this with this kit, hence why the boost is pegged much lower than what the charger is capable of to help keep the stock bottom end alive

I was under the impression that the whole reason the 2.0 kit was pegged so low on the boost was for that very reason. IIRC, they even advise to upgrade internals if the owner wants to push the blower to 300bhp or above. To me, this shows a lot more consideration from Cosworth than many other F/I companies that seem to claim 16 psi on stock internals has no issue longevity-wise.

The high compression FA20 doesn't warrant great results boosted without getting into the guts with some lower compression, forged internals, and whatnot

People always have their retrospect goggles on when they mention things like old LSx, 2JZ, RB26, etc. platforms that can be pushed well beyond their limits, forgetting that back then, emissions and regulations were nowhere near what they are today. The fact that our cars can do what they do at the price point they're at with the regulations in place is astounding to me. Then again, being conscientious of the engineering side of production probably shouldn't be expected of most people..
Not a jab at you, just something I think needs to be brought up when people wonder why this platform is so hard to work with. I actually agree with you, but I think a reliable 250-300whp 86 would be perfect.
