It wont be hard at all to fit the 4efte gearbox, id say its the exact same dimentions as the 2e gearbox, however will probbaly just have a stronger (and not to mention different) gearset. Along with the chance of an LSD
Rember to change the gearbox fluid when you chuck it in before taking her for a drive hahaha
Fuel rail? will come with the engine id say.
New fuel pump will be required, whats with people and putting later model cars fuel pumps in? why not just buy a new one...
$200odd for a fuel pump that will be sufficent, however if you really want, go find a vl commodore one.
the fuel lining? the lines you mean, i got $50 saying the commodore lining wont fit a corolla, im not sure who you would go and see about that, i was planning on doing it to a cynos, so it was EFI already, and the fuel rail, etc everything just bolts together, so i didnt focus on it, (bar maybe an aftermarket fuel pump for later on).
Um, anyone on here help with Fuel Lines?
