Won't go over 4800RPM's...HELP Please?!?!?, 94 celica will not go over 4800rpms in any gear Options

so basically i have a 94 celica, 2.2, 5 speed hoping to do a 3sge but Im still working on getting some of the wiring together before I jump into this.... but first comes first Im using this car as a daily driver right now and Im stumped.... the car runs amazing at idle and low RPMs but as soon as i get up to 4800rpms the car bogs down and falls right on its face in every gear 1st-5th... ive done spark plugs, ignitor, wiries, cap, rotor then new distributor. This pretty much happened out of no where one day it was fine the next day it started to do this. Ive taken it to toyota lol they told me my cat may be clogged so thinking they are the professional i listened to them and guess what? they were wrong.... the timing is the only thing i can possibly think of but i dont want to take it all apart and that not be the problem... any ideas would be greatly appreciated.... while you guys try to help me out im going to do more research on your site about the 3sge wiring. I work at a performance shop so doing the swap isnt hard we put v6's in 92-95 civic hatches so Im sure we can figure out this wiring but still need a little help. thanks in advanced!

im like 99% its timing
does it start easy?
when it gets to 4800 does it sound bogged down?
if both yes, timing

both answers to your question are yes it starts easy....runs great under 4800rpm as soon as i get to that it boggs down unbelievable and i shift so thank u so much if i cant get this beams motor in the next month im just going to do the timing again and see what happens
