6G Celicas Forums

Hi Guys & Girls

I am kinda new to this forum, but have been using it for advice over the years. I have an issue that would be nice to get some clarification before I go ahead with my swap.

Basically, I have a 99 Rav4 with a 3SFE engine. The engine is damaged so I want to replace it as soon as possible.

On the other hand, I have a 95 st202 3SGE Engine.

I know that the engine will fit pretty easily, however, my question is to do with the wiring.

Is there any way that I can reuse the wiring loom from the Rav4 on the 3sge engine as they are pretty similar. I know that I would need to use the 3sge ecu

Thanks for any help on this

i guess the swap would be like this one

you'll need wiring diagrams for both and see for yourself, as always it will be rav4 body loom and celica engine loom

Thanks.

I have seen that site and it does answer a lot of swap issues for me. However he has used a 3sgte while I will be using the 3sge n/a engine.

I need some advice from someone who has experience with the 3sfe and the 3sge to see if the engine looks are interchangeable. The guy seems to have used a wiring guru in the states to solve his problems. This is a very expensive option for me due to the shipping cost of the two looms from the UK to USA and back


I have managed to hunt down the diagram for the rav4. Now I need to find the one from the celica

diferent engines, diferent cars, diferent ecus.

wiring work will always be involved no matter which way u look at it.

to be honest, its not a worthwhile swap

if you successfully complete the swap, the drive will be exactly the same except for a boost in power at 6000-7000rpm, and if you dont get all the ACIS wiring and solenoids hooked up properly those revs will just rev out flat.

the 3sge engine is good in a little sports car where you thrash it around at the rev limiter, its a peaky engine that does all its magic towards the redline. do you really want to drive around town wringing the neck off a rav4?

the most logical choice is either one of the st205 or st215 3sgtes

i dont know enough about the 3S-FE and 3S-GE but i can tell you this, there is nothing wrong with swapping a 3MZ into a car that originally had a 1MZ. just use the intake manifold from the 1MZ and use all 1MZ electronics.

another theory i have is putting a 3MZ into a truck that came with a 5VZ. Just use the 5VZ manifolds and electronics.

so it might be possible to just swap in the 3S-GE and use all the supporting equipment from the 3S-FE

I have already got an 300bhp mr2 with an st205 engine in it. This will be a little play thing that I might take off road. The n/a too me will be a fun little thing. Also for the price that I paid for the 6th gen, It would be a shame for it to go to waste

Thanks dude. It's good to hear someone who has tried or is thinking of something kind of similar

i would say that the cylinder head is the biggest difference. both engines have a 3s block... 2.0L meaning that the "s" and "e" series trans are a go. the 3sgte is obviously a turbocharged engine with a more aggressive head configuration hence the "ge" opposed to the "fe" which is toyotas more economical design. mounts would be the same. you would probably just need management for the turbo set up.

you can use your 3s harness, i did a swap for my friend using a 3rd gen 3sge non beams with his original 5sfe harness, i had to wire up two injectors, re-pin the dizzy, and re-pin the ecu plugs to run the ge ecu. and extended some of the tb plugs and wire in the acis solenoid. it's not as easy as wiring a honda but it's very doable.
