Successfully 3sge swap?

[90camdx4]

Has anyone done a complete 3sge swap? I searched but didn't get much info on it, maybe it's never been done. I want to do that particular swap but, I got feedback from some of you guys and it seems very hard to do the swap. You need the harness that the motor came with also the ecu, why can't i use my original harness and maybe the ecu from my motor or even better the one from the 3sge?

Well, you need the harness, because the motors have different sensors and connectors that arent on the 3SFE. You need the ECU to run the engine, each computer is programed to each engine. You can use any 3SGE ecu on any 3SGE engine as long as they had the same transmission and came from the same generation of engine. IE if you have a 1st gen GE w/ auto trans...you need a 1st gen ECU from a car with auto trans.

The swap itself isnt hard...infact it would be really easy..all the mount points are the same. The trick is the damn parts are a bitch to find if you want to keep it an auto, which i think you mentioned you did. Other than that, its a very simple swap.

As far as i know, only a couple of people have done this swap, but i havent seen either in a while nor do i remember their names. 1fastle was one of them, but personally i think he was full of shit....(long story)

diferent engine, different harnes.. you hav ea gen2 a 3sge would be easier for you then most of us... maybe search a bit more... all engine swaps that arent the original engine are probably harder then most ppl would think... using ya old harness and ecu would be stupid...different engines.. may as well drop in a civic ecu

I've read about one guy in Australia that has done a 3S-GE swap into a gen 2 Camry.

He had a website with pics, but I don't remember the url. Maybe try searching for it on Google or something.

You actually use both harnesses and cut + splice them together. For the most part you'll be using the 3S-GE harness, but you need to rewire the plugs for the fuse box (the one in the engine bay) and whatever plugs into the interior of the car.

Theres 2 harnesses that plug into the fuse box (the one in the engine bay). Engine wiring harness and the engine room harness (it runs inside the car into a junction box).

You can use your stock fuse box and rewire the 3S-GE engine harness. Or use a 3S-GE fuse box and rewire your engine room harness.

I would use a 3S-GE fuse box and rewire the engine room harness. Less plugs to rewire.

And you have to use a 3S-GE ecu. Your stock ecu (3S-FE) will not work.


The engine will bolt up no prob. Wiring is going to be your biggest issue.

There is a few 3SGE's in SV21's floating around in Aus, but the one i do know specificlly of is an SV21 with an ST205 3SGTE. Awesome machine. Engine looks like it was meant to be there.

here's the site of a dude that has done a 3sge conversion in his sv21. he has since removed the 3sge and in place is a st205 3sgte if i'm right...i'll ask my mate that knows him...

^ Thats the one I read about.

Thanks for the link.

I am contemplating the same swap! I've been quoted AUS$1500 for the gen 1 motor supply and fitted, and AUS$2400 for the gen 3 3sge. but i unfortunately dont have the cash though. I have a question though, would the auto tranny that comes with the 3sfe be able to handle that sort of burst in power and torque? and would one require a brake upgrade? (im assuming yes)

I have been told the stock 3sfe manual transmission can safely handle 140hp.

I can see where you're getting at.

My gut feeling is that it might be able to handle a bit more.

Wraith posted a thread about the Toyota GT-Z Comfort, which has a supercharged 3S-FE.

I'm going to guess that TTC either stayed with the same tranny or went with the All-Trac tranny. Supposedly, the supercharged 3S-FE was rated at 165HP.

Thanks for all the replys, but it is very hard to find harness for that particular engine, i found an engine, actually a 1st gen and a 2nd, i know that the 1st gen would work with my old stuff but the 2nd gen would be a bitch to find a harness for. Altough i can slam a 3sgte, cost a lot and too much work involved, it would be a hell of a lot different than what i have now, but i wanted sometin simple. There is always jdm 3sfe, and i read a few guys who did it, oh well i could just turbo the dam thing. how about i use a gen 1 3sge. I wanted to do the swap in the summer, still got lots of time to look for harness and stuff, thanks for the help guys.

[90camdx4]

If i had a 3rd gen camry, would the 2nd/3rd gen 3sge be able to hook with the harness from that gen?

[Tommy]

I wouldnt even bother with a Gen1 GE, power wont be that much better than just getting a JDM 3SFE, and the JDM 3SFE drops right in there, you can use your stock harness and stock ecu. 3SFE's are also quite a bit cheaper than GE's. I got mine for $275+$100 shipping.

No, each harness is matched to each type of motor. it wont be plug and play unless you have the engines matching harness. There are different sensors and connectors for each type of engine....hence the reason for needing the right harness. the only way would be to splice wires from your harness to the new engine and that would be a royal pain in the ass and i doubt you would be able to get it done.

[90camdx4]

thanks stevethecleric, i think a 3sfe would be better for me and like u said cheaper also, i'll search and if there is not other option i'll use a 3sfe.

what are the specs on the jdm 3sfe you got?

The late model JDM 3SFE's are rated at 140hp. They can be identified by their square spark plug boots.
