Gen2 3sfe (USDM) vs. Gen3 3sfe (JDM) - What's the Difference? - Toyota Nation Forum : Toyota Car and Truck Forums

airswoosh1 · 12-22-2005, 12:59 AM

Okay, I've searched through this Camry section of TN and I couldn't find the answer to my question, so here it is:

What's the difference between the USDM 3sfe (found in the US Gen2 Camry) & the JDM 3sfe (I presume found in the JDM Gen3 Camry)?

On ebay, as well as a couple engine importers I spoke to, they claim that you can drop the JDM 3sfe into the US Gen3 Camry? Is it possible? Anyone done it? Again, I'm not asking about the USDM 3sfe to USDM Gen3 Camry, I want to know about a JDM 3sfe into a USDM Gen3 Camry.

And if you can drop (and hookup) that JDM 3sfe into a Gen3 Camry with little to no mods, how much power and efficency are you losing?

I'm sure someone out there has got the answer, please let me know.

a 3SFE is pretty much a 3SFE no matter what. And those importers are crack heads. Yes it will fit, but you need the wiring harness and computer as well as the engine...plus you have to fix one of the engine mounts.

power is about the same, not gonna gain or loose much.

Don't JDM have more/less power? I can't remember if they have stricters or more leanient emission standards......

yea, the JDM one claims 140hp, but i didnt notice a lot of difference on mine, top end was definatly better, but not much else.

Yeah, but I dont think you can really feel 5-10 hp can you?

US spec 3SFE is 115 hp minus 15 years worth of use, JDM is 140hp minus 5-10 years worth of use, there is a difference. Also the head is supposedly better design along with the intake and exhaust manifolds, so thats where you feel the top end power being better.

This was the e-mail I got back from one of the engine importers:

I wrote:

The Camry I have is a '94. But the 2.0L replacement isn't a direct drop in, correct? For that to work wouldn't I need to modify the wiring harness, have the ecu, and modify one of the engine mounts?

He replied:

all of your external components bolt up, there are no other modifications except for the rear motor mount the we modify and send with it. There is an exchange required on the rear motor mount...

Tommy · 12-23-2005, 01:09 PM

what they are saying is, that you are gonna need to take your 2.2L intake, exhaust, PS, AC, distributer, and all that fun stuff and put it on the 2.0L

Now, I had to do that with my 3SFE too. I just cant imagine the ECU matching. If you replace the 3SFE's intake and fuel rails and distributer with your own, i guess that your 5SFE harness would match then, but you're still running a 2.0L 3SFE off of a 5SFE computer, and i dont know how well thats gonna work.

There are actualy 3 versions of the 3S-FE

Euro spec: 130hp @ 5600rpm and 133lb/ft @ 4400rpm
JDM spec: 140hp @ 5600rpm and 137lb/ft @ 4400rpm
US Spec : 115hp @ 6000rpm and 124lb/ft @ 4800rpm

Edit: converted Metric Nm into US lb/ft

I Have driven an imported US gen2 Camry, and it felt like driveing a dead herring
compared to my Euro gen2 Camry.

You get a bit more power out of the non-USDM 3SFE in part because JDM emissions controls are not as strict, that's one key point I remember reading back in the day... I want to say talisman18 made the point but he hasn't been on in a long time and my memory isn't that great atm...

But why a 3S-FE into a gen3? Even if it was a 5S-FE car to begin with, you're replacing a larger motor with a smaller one and giving yourself more wiring headaches than maybe it's worth. 5S-FE midrange torque owns 3S-FE midrange torque. Sorry to go O/T but this was the first thing I thought reading the thread.

Tommy · 12-23-2005, 07:05 PM

I was a JDM 3SFE Camry owner also, and yes, emmissions made most of the difference. Ive also been told that the later ones had some modifications made to the head and intake manifold.

I would definatly skip the 3SFE and source out another 5SFE. Plenty of those motors are lying around, im sure you could find one with low miles. Remember they used them in gen3 and gen4 camry's, so you could actually probably find a 5SFE thats newer and has less miles than a JDM 3SFE.

Zandro · 12-23-2005, 07:22 PM

Why not get a JDM spec 5S-FE? it has 140hp @5800rpm and 145lb/ft @4400rpm.
Remove the CAT and put on a CAI you got yourself another 7-10hp more

Tommy · 12-23-2005, 08:28 PM

^there were no JDM 5SFE's

RICO8458 · 12-23-2005, 08:35 PM

looks good.

Oh but youre wrong, they are missing the Oxygen sensor and the
catalyst. my father has one i and can take a picute off it to prove it

You see the Euro spec engine and the JDM engine are identical, our cars
comes out of the same production line as the JDM cars, my 2gen is and so is my fathers gen3.
There realy aint no difference between the Euro spec and the JDM spec engine besides the tuning
off it since the japs makes a higher quality gas than europeans and americans produce
