Even 300 PS on FA20 without FI is possible. But here were are takling about a car that should be road drivable. The torque cuvre is so flat, almost 200 Nm @ 3000-7000 RPM. Move that higher for worse daily drivability, you'd get about 230 Nm @ 5000-8.000 RPM with power about 250 PS @ 8.500 RPM. It should be doable on keeping 2.0l displacement. Increasing stroke would be better for torque and city driving, but the engine would be less rev friendly. I am not sure is there is place for increased bore.

Stroke 86 x Bore 86 = 1998 ccm
Stroke 86 x Bore 90 = 2188 ccm
Stroke 86 x Bore 92 = 2284 ccm
Stroke 86 x Bore 94 = 2387 ccm
Stroke 86 x Bore 96 = 2490 ccm

IMO 10 mm increase in bore is the max possible, but even this I doubt, is would mke the walls 5 mm thinner.
