The engine's in 7th and 6th gen Celica, Why did they change?? Options

So i was thinking the other day of the difference between the motor's in the 6th gen and 7th gen celica's. The 3sge engine was a very potential motor with 3rd gen producing 177 hp 142 lb torque, 4th gen "Redtop Beams" 197hp 152 lb torque and the 5th gen "Blacktop" found in the Altezza producing 207 hp and 159 lb's torque. I would say those a pretty impressive numbers.

Honda has had their vtec since the nsx first came out in the early 90's and they have been improving ever since. So why did toyota decide to go with a 1zz-ge and 2zz-ge engine for the celica. I mean the displacement went down in .2 liters. The 1.8 ltr 2zz engine came with vvtl-i to compete with honda's vtec? In the US, the celica only produced a 180 hp and in japan it produced 190 hp. Then there was the trd celica which produced 194 hp. Still that wasnt even enough to touch the Integra type r B18c5 motor which produced 195 hp and had around the same torque as the 7th.

So why didnt toyota stick with the 3sge. They could have produced an 2 ltr engine that had around 215 hp with vvt-i on the intake and exhaust manifold just like the 3sge blacktop.

hmm i see alot of guys swapping in 3S-GE Blacktop into their celica st182. what did they have to change to make this possible, do they still use the altezza ecu?? Swapping the head from the blacktop, making a custom valve cover painted in the red thats painted on the 3sge redtop and the same pistons used in the blacktop with an aftermarket ecu... would the torque be the same as a blacktop beams??

Recently updated video from japan about a few months back of his SS-III ST202 vs an MR-S fitted with a 2zz-ge im assuming at tsukuba. I also asked him if he has any videos of him versus an Integra Type R DC2 and then i translated it using google and left a comment...
