Ok. You have a number of swapped engines which I would advice to you.
1) 4AGZE
2) 4AGE
3) 4AGE 20v Silver top
4) 4AGE 20v Black top (last generation of the 20valve 4age engines)
If you could get the 4AGZE, then get and do a swap. If not get any of the other 4age.
These engines will swap back into your car since it is carrying the 7AFE engine. An "A" engine. Everything would mount back powerly.

After that, it is very easy to get performance parts for the 4AGE engines.
