"The 2AZ-FE is a 2.4 L (2362 cc)Bore is 88.5 mm and stroke is 96 mm. Output is 157 hp (117 kW) at 5600 RPM with 162 ft·lbf (220 N·m) of torque at 4000 RPM. The 2AZ-FE also has a one-piece cast camshaft and cast aluminum intake manifold.


A different version found in the Toyota RAV4 produces 165 hp (123 kW) at 4000 RPM and 224 ft·lbf (304 N·m) of torque at 4000 RPM."


where is the torque coming from? Is it a smaller bore but stroked motor in the Rav4?

I don't know where you got your info from but the toyota website Rav4 2AZ only puts out 166 hp @ 6000 rpm and 165 ft.-lb. @4000. Specification wise it's basically the same motor.

I also think that the tC uses a glass reinforced plastic intake manifold, and if it has one piece camshafts I'm pretty sure it has 2 of them.

I read the tC's 2AZ has a different intake manifold because of space issues.

The wikipedia description says the 2AZ is made in Kentucky, but isnt the tC's 2AZ made in Japan (along with the rest of the car)? Maybe that accounts for something lol.

Lip

haha. well there you go.

sorry... this drivetrain is new to me. i'm looking around and trying to find info.

like..the 2az-fse etc. just surfing and searching

senseiturtle

- No N/A four-banger that i know of can put out 224 ft-lbs. Torque is a function of displacement .

We've got one of the torquiest n/a 4-bangers out there, actually very close to some small v6's.... (the hyundai 2.7L, and vw 12v VR6 for example.)

We can also compare the tC version with that used in the Camry. Previous generation Camry internals were supposedly the same, but people found out those bearings don't fit the tC engine. The new Camry engine is again supposed to be the same, yet has 9.8:1 compression, compared tot he tC's 9.6:1. It seems like Toyota does something a bit different to the engine for each car it's used in, such that all "2AZ-FE" are not the same, even internally.

travisallenn

which 2az has more power and torque?

lets just swap ecu's and some components and hope it works

The "FSE" is code for a diesel engine in Toyota's lineup. I think the unit for "224" mentioned by Wikipedia is Nm not lb.ft. of torque (224Nm=~165 lb.ft.)

The previous Rav4 had a 2.0L I4 diesel option code name 1AZ-FSE. Don't know the specs for that one. The current Rav doesn't have a diesel option for Japan. Diesel version is certain for Europe.

I thought FSE was direct fuel injection?? Maybe I'm wrong but I am pretty sure that is what it stood for.

ahhh....let me input...yes it is totally normal for a diesel motor to put out enormous amounts of torque compared to horsepower..because the ignition system is vastly different than that of a regual fuel injected vehicle....look for example in the VW golf TDI and the various mercedes diesels, diesles also get killer gas mileage......as far as the engine code goes..... 2az would be the engine family ( ex: 4a, 3s, 2zz) f = head machined for fuel mileage, e = electronic fuel injection

for an example a 91 celica came with 3 motors ill use two for this one
3s-fe in the GT
3s-gte in the GT4(alltrac)
we can also use the ever popular 2jz-gte(turbo supra)
AND 4A-GE(85-87corolla gt-s)

notice the engine code at the beginning and yeah i guess i was right
f= head machined for fuel mileage
e = electronic fuel injection
g = high flow head
t = turbo

hope this makes things easier for you when looking into the toyota engine family

OuterHeaven

I understand the basic Toyota engine code and by the way it’s "AZ" as the family. The number in the front of the engine code is for the stroke length or otherwise the total displacement (i.e. 2az is 2.4L while 1az is 2.0L). Anyways according to Wikipedia the 1az-fse is a direct fuel injection which is also gasoline. Also I do not think there is a 2az-fse in the states anyways (only Japan might have one). The differences in power between the rav4 2az and the tC is the size/shape of the intake manifold and exhaust manifold/exhaust. Also there might be slight differences in the internals but that is something someone will have to find out by actually comparing the 2.

childdamien

ahh you caught me....i knew i would miss something i havent had to talk toyota engine code in awhile

This is tC specific specs...as far as I know by my experience it is identical engine specs to the camry. I've always found this info useful, so hopefully it will help here as well.

now that I look hard a second time...I think the spark plug spec is wrong. I'm pretty sure they are factory platinums...usually platinums are like 100k plugs. Either way, 50-60k is pretty realistic.

childdamien

thanks for the spec sheet

leastbay

spark plugs in my 06 are iridium not platinum supposedly good for 120000 miles

nodsetse

Read my post...tC & Camry engines are not the same, close but no cigar.

tCyoung1

i guess i was wrong about every 2AZ being the same
