Ae90 4Af/6Af

[ke70trent]

so i've just got myself a ae90 hatch and I'm having trouble working out what engine is actaully in it! thought some one out there might have a better idea! so on the vin plate it has 6-AF (the 1.4 DOCH) But in the engine it has a sticker saying "4A 3m/t"? and on the rego paper it has for the engine no. 4A9144979 so with a quick bit of research (wiki) i think it is a 4AF DOHC 16v? as the photo is the exact same setup on top to look at! but the 4Af never came out in a car in australia! so i've got no idea whats going on! other then possable jap import engine? but who would import a carbie 4A engine?

4afc was released in aust, have one in an 1989 ae92 cs hatch.

 

quite possible the original motor died and was replaced.

Trent your research is correct :y: The 6af is the 1.4 twincam. 4af is the 1.6 twincam, if there is a "C" after the 6af stamping it means the car is a carburettored version (which you

would probably know).

 

The other sticker on the cam cover you speak of 4A3m/t tells you engine capacity and type of gearbox package, It sounds like a 1.6 with manual transmission. Looks like the previous owner did the car a favour :)

 

Have you put a rides thread?

'C' does not mean carburetted, it stands for California emissions spec. It almost universally appears on carbied Toyotas, but not all carbied Toyotas have 'C'-spec emissions packages (all dogs have four legs but not all animals with four legs are dogs)

 

3m/t is weird though as that would by convention mean a 3-speed manual (which doesn't exist in Corolla-world). 3-speed auto, yes, but the manuals were all 5-speed.

Thanks for that Ian, I should have known that it stood for Californian spec emissions :y:

The other sticker I can only think of is the 3a/t denoting it as a 3 speed auto. Maybe a typo from Trent?
