1995 camry 3sfe jdm into 5sfe car engine swap

kentarver · 08-16-2006, 03:53 AM

Hello Guys ,

Please bear with me as I am new to this forum and just a shade tree mech.

I inherited this project from my son-in-law .

The 1995 originally had a 2.2l engine in , what I believe you guys call a5sfe .

He succumbed to an ad on E-bay for the JDm 3sfe 2.0 L engine .

He was told and I quote " he only had to drill two holes in the lower and than transfer all of the original engine's externals to make the harness work" .

when he abandoned the project , he had the motor in the car and was aggravated with the electrical connection differences he was running into .

My question is this : Is this project do-able ? Will this JDm 3sfe engine actually work in this 1995 Camry ?

I have searched many posts on this site and I still don't have a good understanding of wheter tis works or not . I have seen discussions about the ECU and the computer , hte Wiring Harness and also motor mount problems .

What it boils down to is this " I still don't know what to do with this car .

Even as I type this message , there are multiple dealers on E-Bay offering this same engine for installation in the same year . Who is right ? Who is wrong ?

Do you have the 3S-FE wiring harness and ECU? It sounds like that is what you need to bolt it in (with the exception of a small issue with one of the engine mounts).

Another approach is to put the 3S-FE shortblock into the car and put all the 5S-FE parts onto it and use the 5S-FE wiring as it used to be.

In Answer : I have the original stuff from the 5sfe and just what the engine salgagers in Japan left on the engine . I don't have harness or Ecu . It looks like my Son-In-Law had startec to change over thestuff from the 5sfe to the JDM 3sfe . nbut since I wasn't there on teardown I don't know what partd came with which engine .

I have also seen discussions concerning the MAP versus MAF systems ? Does anyone here know if the 3sfejdm and the 5sfe usdm motore are using the same system ?

Thanks in Advance !

P.S. This is so much fun , I may quit my regular 9-5 job ( computers) and take up Toyota repair fulltime !!!

Based upon my limited information (since numerous changes have been made to both engines):

5S-FE (D-type EFI as used in the autoshop101 manual on EFI) uses a MAP (manifold absolute pressure) sensor and the 3S-FE does not.

3S-FE (L-type EFI) uses an vane-type AFM (air flow meter) and cold start injector, and the 5S-FE does not.

Neither one uses a wire-type MAF (mass air flow) meter

For general desciptions of the various systems involved see:

and others at http://www.autoshop101.com/

Particular information related to the 5S-FE:

Here's a link to a wiring schematic for a 1994 Camry which should be quite close to yours:

Here's a link to a harness repair manual:

Here is the general link to repair manuals for 1994 Camry:
http://www.turboninjas.com/camry/

Particularly see page EG1-164 and so on in:
http://www.turboninjas.com/camry/eg1.pdf

(All of the above links are in the sticky post at the top of this forum)

It appears that your best approach would be to duplicate the 5S-FE as exactly as possible using the above information as a guide, seeing how you are forced to use a 5S-FE ECM. Maybe someone with further experience will post and guide you more precisely.

Finally I have found someone who has the same problem I have! Only my car is a 93 Camry, but from what I've heard they're the same engine. I also fell victim to saving money by buying the 2.0 3SFE engine to replace the stock 2.2. I was also told that the only conversion needed was on the mount and the ECU needed swapped over. I've replaced so many parts it seems like a new car, yet it idles rough(especially w/ the AC on), and lacks power after the RPM's begin to peak. I was told to swap the original injectors to the 2.0 also.

Any help would be greatly appreciated!

I've been told the fuel pump could be bad, or that the computer needs swapped out w/ the 3SFE.

Please help a rookie get his head on straight!

I believe you need to use the 3S-FE injectors and ECM. The injectors may be dirty and need cleaning. The 5S-FE injectors may be the same as the 3S-FE ones.

Well Guys ,

Here is the intel I have been able to winnow out of this forum so far .

The 3sfe engine will replace the 5sfe engine with the following changes :

#1 The rear motor mount must be drilled to fit the 5sfe car mounts . One of the sellers on E-bay has a good JPG showing where the holes go . If you can't find it , I can e-mail to you .

#2 All of the external parts from the 5sfe engine must be transferred to the 3sfe engine . This includes the intake and exhaust manifolds . The injectors , the fuel rail and any and all sendors / sensers that are unique to the 5sfe engine .I was told to treat the swapout like a long block replacement and to strip down the 3sfe engine and use the original parts from the 5sfe . You must also relocate some vacuum hoses located under the intake manifold and a couple of sensers / sendors / vacuum switches from the same place on the 5sfe to the s3fe to make all of the other stuff connect up properly . This is of course assuming that you use the 5sfe ecu and harness .

I haven't finished it yet but I am getting close . I should be done with it this weekend and I will report back here .

I have had to track down a ported vacuum switch for the VSV for EGR system and also the oil pressure sendor. They were broken on both motors , Go Figure !

I basically have to just track down two more vacuum connections and install the cooling system and the belts and I will be in business .

Wish me Luck !

Hello Guys !

Well , I finally got the 3sfe jdm into a 1995 Camry 5sfe car .

What we did was transfer all of the external compoents from the 5sfe engine to the 3sfe engine . We were told to treat it just like a "Long Block" engine replacement project . We utilized the ECU , Wiring Harness , Injectors , both intake and exhaust manifolds, all to the little sensors and sendors and other ancillary components that were originally attached to the OEM 5sfe engine .

The ONLY Problem we have had so far is the rough idling and poor engine performance . Also the real indicator of trouble was that the Exhaust manifold was getting extremely hot . What we have discovered is that both of the CAtalytic Convertors in the existing car chassis were plugged and not allow the exhaust gases to flow out correctly , thus the overheating manifold and poor performance .

After a trip to the local Midas store ,the car runs smoothly ans seems to be in great shape .

The original owner had stated that the engine had "Burned Up" . I wonder if the clogged Cats were the cause of the original failure ? The original 5sfe engine had only 95,000 miles on it when it failed . I would think the lowered performance would ring bells for somebody ...

Well Live and Learn .

The Moral of this story is that the 3sfe JDM 2.0 liter engines will indeed work as a replacement for the 5sfe USDM ENGINE !

GOOD L.UCK !

if it was running that rich (to plug the cats) you might want to check your o2 sensors. don't want the cycle to start over again. mike

2000izusu has a good thought here. Thinking along with him, I would also test the engine coolant temperature sensor (Toyota calls it an ECT sensor) and replace the thermostat. If either of these 2 items are out of spec, they can cause the engine to run richer and eventually ruin the cat.

Good luck with the new engine.

Hey Guys !

Thanks for the info on the running rich scenario .

Is there a definitative test for this situation ?

Would the ECU be throwing codes if the mixture was too rich ? So far the Code indications are silent .....

How do I find this condition if it exists ? The 3sfe jdm engine in place now has a different thermostat in it . The ECU and Throttle body are original , however .

Thanks in Advance for any Help !

Brian R. · 09-27-2006, 10:15 AM

Check your plugs if they were new. They are supposed to be a light color like tan or light grey. If they are black, then you are running rich.

Alternatively, check the output of the HO2 sensor.

Mike Gerber · 09-27-2006, 11:02 AM

On OBD1 systems, sometimes there is a code for the engine coolant temp sensor and sometimes not. I have never understood why that happens. There definitely is no code for a thermostat that is stuck in the open position.

2000izusu · 09-27-2006, 11:19 AM

the only way to tell for sure if the 02 sensor or sensors is (are) bad is to have it hooked up to a live data diagnostic computer. this will also tell you if the coolant temp sensor is working to. but me being a shadtree my self and not having access to an obd 1 computer i just replace the o2 sensor as prevenative maintenance (every 80k). the way i understand it is, sometimes a bad 02 sensor will trip a cel and sometimes not. toyota sensors are probably going to be the best buy, but if you try aftermarket make sure you do a search for what ones work and what ones don't, with the camry.

Liquormeister · 10-03-2006, 05:51 PM

I was still using the 2.2L ECU and was told that the rough idle and performance problems I was having were do to the fact that the ECU was sending information to the car for a 2.2L, causing it to run rich, etc. I purchased a 2.0L replacement ECU, but upon installation found that the wiring harness didn't match up.

Is there a wiring harness adapter? I inquired with my local Toyota dealership about reprogramming the stock ECU, but was told it wasn't possible. I'm so close to solving the problems, yet am having a hard time finding knowledgable people to help me.

Any insight would be much appreciated.
