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.

haha yea thats what I was just going to say. well I still have on answer to my question yet.

ok thanks for clearing that up about the 2zz-ge. hmm ive never seen a k20 into a 7th gen celica i was looking for a video on youtube but had no luck with it....

also what i dont get is why have several people with st182 decided to swap in 3sge blacktops instead of the redtop. I mean the it would be a hell of a lot cheaper right, oh well i'll have to do some research on my own

oh and actually raven yes that is a true blacktop well at least i think it is by the way the header manifold looks, but at the same time the intake manifold is black why is that shouldnt it be red or better yet silver looking like the stock blacktop beams?? or wiat hold up a minute, it just hit me as I'm currently looking for how to convert a blacktop into fwd...

would you be able to buy a 3sge beams blacktop and put the redtop intake manifold on the blacktop engine???
