gotcha.
ok when i did the efi in daisy, i ran the fuel return line back to the tank using the charcoal canister vapor line. (don't know what kind of emissions equipment you guys have). the wiring harness was easy; the 1983 starlet efi was a factory add-on, i just snatched the efi harness, wired up the main relay, hooked up +12v, ign, start, ground, and a/c.
i used the in-line starlet fuel pump, but i don't know how well my feed is as the line is so small and THERE IS NO SUMP; i go around corners hard with less than 1/4 tank and it will starve.
i don't know much about the later corollas, but i don't see why the rear axle wont fit.
