Therefore you can see why peoples scepticism when they ask you why on earth you're tuning a FE engine that's also found in the Camry. And although I understand the reasons for Toyotas discontinuation of the GE in the sport compact and tuning market, I (like most enthusiasts) don't support their decision and wish they had worked around it. Simply put, no one would bug you if Toyota had produced a 2AZ-GE that put out 210bhp stock and was shared with the 4 cylinder Camry SE and XRS models.

With modern engine design, the G vs F head design (specifically the valve angle) is almost a non factor. In fact, if you look to motorsports and motorsport derived engines, you will see that they have been using narrower valve angles, as they have been coming to the realization that there is more potential. Given also that Toyota only has one G head engine in production (2UR-GSE... which gives a whopping 0.6hp/ liter improvement over the conventional 1UR-FSE) it's not as if one could choose to tune say a 2AZ-GE rather than a 2AZ-FE, so it's a fairly moot point.

I think it was a cost issue as only the 2ZZGE had the VVTL-i as far as I know. And it used some pretty fancy metallurgy in the block and head too, I believe.

Technically iVTEC is the same as VVTL-i (let's not put the cart before the horse)
