Hey guys, hope everyone is doing great. I have a few questions about a swap that I'm attempting to do with a few friends. Swapping a 4efte into a carburetor ep82 running 4ef engine (4e carburetor engine).

What I've at the moment;
- running 4efte engine with ecu and wiring, its actually in a corolla atm.
-stock ep82 with a 4ef engine(carburetor) and in running condition also.
My questions are what things do I need to swap specifically and need to change.. like how to tackle the whole fuel system
and is there more obstacles that I'll encounter?
Every help is much appreciated guys, kinda frustrating taking to running cars and tearing them down lol, but that's the fun being car lovers.

Unfortunately I haven't seen a 4EF in person so can't really comment too much.

The UK didn't get that engine - closest we got was the 2E carb (which not many survived).

If you could photograph the fuel lines, tank, pump and connections we might be able to compare to the 4EFTE though?

hmm okay, car is not in my procession yet, once I get it i'll do that. But lets say for example 2e carb, when you do that swap, what things need to be changed? and swapped?
both are carbs so I assume should be fairly same

(Once again I'm 100% sure I replied to this earlier..)

It's been a serious number of years since I've seen a carb engine but I'm near sure the fuel feed, return and vent pipes are slightly different to the EFI model. Should only be a matter of adapting them if so.

I'll grab a few pics of them in a GT so as you can compare.
