diffrence in a 4af and 4afe engine

[atxcorolla]

are parts compatible such as exhaust components and engine parts

[Tuskanr]

well one is fuel injected and the other is carburated. So I'm not totally sure, but i would think so

[Flashmn]

pretty much, depends on what generation 4A-FE

[Rookie_One]

for the first gen, the heads arent the same (the injector are screwed in the head) but the two heads still enough similar as many piece are compatible, i risk myself to say that nearly 89-90% of all the pieces of a 4A-FE and a 4A-F are interchangeable, the block and the head arent for sure thought (the 4A-F fuel pump is a mechanical one that is placed on the engine block so....)

for the second gen, thats another story, as only the pieces that will fit on the 1st gen will fit on the 4A-F, with the condition that between the 1st gen 4A-FE and the 4A-F the piece was already interchangeable, but since i do not know what pieces are compatible between the 2 gen of 4A-FE i wil not risk myself on that terrain

[Flashmn]

Injector places on the 4A-F are there, they just arent drilled open. Easy to get machined. Fuel pump hole is easy to block off with a block off plate.
Anything from the 2nd gen head is not compatible, neither is the lower end.

so even if i was to convert it to efi it would still not take the headers and if so what would be the diffrence in it being carburated and efi

[Rookie_One]

fuel pump, fuel lines probably(EFI function at a higher pression), injector, intake, fuel tank(im not sure about this one but since the EFI fuel pump is in the tank....), ether machined the head or get another head for the injector, ECU, ect.....you would be better by just changing the engine son.

[Flashmn]

Fuel lines have nothing to do with precision or did you mean pressure? Nevertheless they are very close 4A-FE has 8mm lines, 4A-F 6mm, material is the same. I replaced mine with plastic lines.

Getting injector bungs drilled in the head is easy.

you would be better by just changing the engine son.

BRRRRT wrong answer, I converted mine to EFI...

[Rookie_One]

well i find it less time-consuming to simply change the engine >_>

[Flashmn]

Depends.. I can take off a head and have it back on before dinner

[Rookie_One]

well im no good for machining pieces so.....

[atxcorolla]

even so that would convert the engine to 4a-fe ok so now would it be able to take the headers or catback or even cam gears and if it can why cant they be used by the 4af

[Rookie_One]

i THINK that the cam are the same, headers and catback too, but i cannot be sure (last time i saw a 4A-F its nearly two year now so....)

[atxcorolla]

ok any ideas on where would be a good place to get a new engine
