AE9x/4afe Rarity in the garage.... - Toyota Nation Forum : Toyota Car and Truck Forums

toyotaspeed90 · 01-10-2009, 08:21 PM

So.... not sure outside of the US, but I would assume the 4afe in my garage is pretty rare...

pulled from an 88 alltrac wagon..... has a thrown rod, so the block sucks....

but it's an 88 efi setup on a 4afe..... the later 4afe's have injector ports on the manifolds and it's all one unit...... on this one, the ports are in the head itself.

Not 100% sure of what the 90-91 4afe's have for this setup..... I can't recall, but I can say that the manifold definately looks different than my old 90 intake manifold.

Unfortunately I don't have the injectors (as they had to stay with the cars electrical system, which now has a 4afe from 94 prizm bolted in) but I was surprised to see that they were green top high ohm dual outlet port injectors.... something I thought only later 4age's had!

also.... on the ae95's.... the "hump" for the "exhaust" is actually larger on the passenger side only because of the catalytic convertor.... if someone were to do a custom AWD in an ae92 they could probably squeeze both by without a cat.

87-88 was the 4af but some 4afe's snuck by in 88
all 1st gen 4afe's have injector bungs in the head it's really the only diff from the 4af

the 2nd gen 4afe's (93-97corolla and st celicas) i believe has injectors in the plenum.
tell me if this looks anything like yours (fuel-rail/fpr will look diff)

A trip to any self service junkyard will convince you that 4AFE's are not rare. In fact the AGE is rarer - I've only seen them in junked prizm's. There's a least 6 in every yard I've been in in Portland, San Diego and Orange County. Problem is most of them are beat up. Generation 6 is 88-92 so almost every aspect of your EFI is the same except depending upon the Emissions - CA or Fed.

You totally missed it.

not saying a 4afe is rare..... and if you believe that I am, you should read more of what I write on here..... 4af was dominant in 88-89 and the 4afe lasted from 90-97.... even my own SR5 had a 4afe in it.

the 88-89 4afe is rare..... the parts I have are from an 88 4afe alltrac.

I helped a friend and we ended up installing a 94 4afe into his 88 alltrac due to a thrown rod by the PO.

The 4age being rare?! Haha.... most the cars I drive have 4age's in them..... as of this moment I have 2 4age's in the garage, a 7age that needs a crank, another 4age car in the driveway, and a JDM 4agze car in the driveway.......

My Co-worker has an 89 Alltrac DX sedan with 4afe motor and overdrive. White with blue interior and 200k miles. 1989 EFI motors had 90 bhp while 1990 motors had 100 bhp like my 90 3speed prizm base. Correct? If so what changes were made between 89' and 90' EFI motors?

jmaz87 · 02-19-2009, 04:10 PM

that's what we are trying to figure out...

i've never seen a difference between the 88 and 90 4afe's maybe the intake at most could be diff. but i've definitely never seen an 88-92 4afe with injector bungs on manifold...

and i've got an 87 4af fwd talk about rare...

freakinbox · 02-19-2009, 05:54 PM

ok basically what I am thinking is that the 88 and 89 4afe's were obviously the first 4afe's. Since the 4af was run in the sedan and coupe until 1990. Maybe they decided they would change it for the sake of keeping the same head of the 4af for all cars instead of switching to the all trac head. I didn't think there was a power difference between the 2 4afe's for 88=89 and 90 - 91. I doubt they had just 90 hp as the 4af had 91 hp. Thought the 4afe's later on had 105 hp, not 100.

jmaz87 · 02-19-2009, 06:17 PM

what you said about the green injectors got me thinking. did you notice a difference in fuel-rails too?

i have seen those injectors in an early model prizm hatch, there were two nearly identical cars and this one had a forged aluminum oem fuel-rail as well as those injectors, both of which are in my 4afte setup now.

it probably is rare, as soon as i noticed the shiny fuel-rail i grabbed what i could. But i don't remember anything else striking me as diff. i've never seen a 1st gen 4afe with injectors on the manifold (other than CSI)

jmaz87 · 02-19-2009, 06:26 PM

this is what everybody recognizes as the 1st gen fuel-rail (91 here)

this is what i pulled off the junkyard prizm. dunno why my stock one is shitty cast aluminum and this beauty is forged but it looks identical to the large-port fuel-rail other than the 4afe mounting locations...

freakinbox · 02-19-2009, 07:42 PM

hmm I noticed the colour of your exhaust manifold. How some of the areas are different colours. I have a similar thing with mine, noticed it when I changed the head gasket last time. That part way down it was one colour and the rest was different. I was thinking that I get it glowing where the colour is different close to the motor. Thinking that it's a right assumption considering you have a turbo and yours is the lighter colour farther down then it turns the dark, almost black.

jmaz87 · 02-19-2009, 08:42 PM

i wish i could upload a pic right now but this is an older one and yea it looks like the manifold is lighter color in the regions that get hotter...

why don't u get a header? it's like 70usd!

toyotaspeed90 · 02-19-2009, 08:44 PM

I would be more interested to see the coolant lines/sensor unit on a 90+ 4afe.... I'm going to guess that's the difference....

that being said, I haven't had a 4afe in my possession in a long time....

freakinbox · 02-19-2009, 09:26 PM

why get a header? the pace setter ones are apparently really shitty. Besides from a manifold to a header you won't really notice anything as the manifolds on newer cars aren't like the ones on the old 70's cars. Which were a tube with the inlets from the engine going into them and 1 outlet along them somewhere.

Hmm, I believe that my 90' Prizm had the same fuel rail as the one you pulled from the Geo at the junkyard. The one in the first pic doesnt look familiar. I'm almost certain I read somewhere that there was a 10bhp bump for 1990 Corolla/prizm models with 4afe...
