actually its a pretty nice engine that using both port and direct injection with whopping 40% thermal efficiency aside you cant get 30whp by changing here or there without remapping out of a 2.0L engine..
few ways to achieve such results by using a lower gear on stock run and higher with bolt ons.. you can multiply kW by 1.4 not 1.34 like it should be.. or different fuel.. i guess the half of the gain d be plausible.. or after remapping the engine it can produce 50% more power than Toyota engineers could achieve which then these guys deserves a trophy..
