you can do a 5AGE...
20V might not be worth it, honestly.
Ballin on a budget you might want to just do 4AGZE + turbo.
3SGE Beams motor (around 220whp maybe) is where you will want to be exactly but it is kind of costly.




as for the distributor you can relocate it to the front with a GS coilpack where the cam gears are...or hammer the shit out of the firewall in the back or cut a hole and make a box for where the distributor is, but whenever you want to change it, it's kind of in an awkward spot.


if you are venturing outside of toyota...best choices
SR20DET
