The 'e' means FI right? - Toyota Nation Forum : Toyota Car and Truck Forums

I see many people with carburatred 4ag motors saying they have a 4age... the 'e' is for fuel injection, right?

toyotaspeed90 · 11-28-2005, 01:39 PM

um, '4ag' is just short for 4age. there really aren't a whole lot of people running a carb'd 4ag......

but yes, E means electronic fuel injection

aaron7 · 11-28-2005, 01:51 PM

No, 4ag isn't short for anything, it means carb motor from what I can find. That would be like someone with a 4afe calling it a 4af, which is a carb motor. My 4af is no way anything near a 4afe! lol

4A-G is a carbed 4A-GE period.

aaron7 · 11-28-2005, 03:06 PM

Right, that's what I thought.

ok. so, everyone on www.club4ag.com has a stock carb'd 4ag. Oh wait, there's no such thing. Thousands of members on 'club4ag' and very few actually have a carb'd engine. It's a shorthand for those of us too lazy to type 4age. I do it all the time myself.

you need to distinguish between a 4af and 4afe because they are essentially different setups from stock.

i don't think the 4AG/E ever came out carbbed in stock form... so i guess you can say its a carbbed 4AGE...

Exactly as different as 4A-G and 4A-GE are. Who cares if its stock or not, the E means EFI, saying a 4A-G is saying that you have a 4A engine, G head and no efi, or a carbed 4A-GE.
Formula atlantic 1st gen was a 4A-G because it was carbed as stock form.

Right! There's no questioning it. The 'e' means fuel injection. If you don't type it, then you are saying you have a carb. I understand shorthand, but dropping one letter?? That's just lazyness :P

ugh........

right. my corolla has a 4ag and my mr2 has a 4agz

they must be carb now.

aaron7 · 11-29-2005, 01:09 PM

That's what you are typing, yes technically.

Flashmn · 11-29-2005, 02:05 PM

^ Yup.... and both would technically also be possible.

check that site out, it has a link on the page that says engine codes explained. But "e" def. means FI.

Dr Tweak · 11-30-2005, 12:03 AM

The bottom line is, E stands for EFI, but not everone uses it and just because they leave off the E doesn't mean that it's carbed, and just because they use the E doesn't mean that it's EFI. People just forget. But technically, the E should only be used for cars that are EFI. End of story

toyotaspeed90 · 11-30-2005, 01:15 AM

right. but my point is 99% of those who say they have a 4ag in their car doesn't have a carb setup.

i'm saying this so you don't go around asking people or expecting that anyone who says it has a carb setup in their car.

hell, the little logo i've seen on tons of ae86 that mock the 'intel inside' logo with '4ag inside' is ON several efi cars.
