So, I bought my first Rav4 about a month or 2 ago. I've been in the celica world for a long time and I wanted a winter beater. As it turns out, the 3s decided that it was going to start Rod knocking like a beast. Needless to say, car needed work.
I had an old 5s just sitting on a pallet in the garage collecting dust. it came from a 94 celica, and it ran when it was pulled. Now that I've got everything out of the Rav, and from what i'm told, the 5s block will need ground on the back to make space for the transfer case, but otherwise it should be pretty straight forward I think. I haven't had time to research everything... but to be honest there isn't much out there on this particular swap because there aren't that many gains to be had. For me the gains are purely $$$. if you guys see anything glaring, PM me and let me know if you would.... The Plan 1) swap wiring harness from 3sfe to 5sfe 2) "depending on how the ecu works out", swap over exhaust manifold because of OBD1/OBD2 differences in the model years 3) hook tranny and T-case to 5sfe ( grind block as needed, additionally brace as needed for missing mounting points) 4) repair subframe rust, mount engine and tranny to subframe - reinstall in car 5)hook everything back up including 3sfe ecu to run engine. ** Pray ecu can deal with extra stroke/air and change fuel delivery to accomodate** 6) ** pray that i don't need to swap injectors to do this to get engine to running** - Does anyone know if there is much in the way of difference between the injectors? basically I'm looking to run the 5sfe like a stroked 3sfe. Should work I'd think. -------------------- ![]() |

@batman - I appear to have located at least the crank sensor part of this as an issue. I'll illustrate in the below pics. may have to try and run the 5s ecu..... Do the later 5s's have the cam and crank sensor?
In any case - here we are. Wiring harness is swapped over mostly sucessfully. Issue #1 - AC compressor plugs are different. Maybe can swap over 3s compressor? Don't know yet, need to investigate. ![]() Issue #2 - Random plug available, not used on 5s, used on 3sfe. - This is likely the aforementioned Crank sensor ![]() The wiring on the other side of that for the 3sfe goes down beside the crank pulley. this COULD be a major issue. We'll see. ![]() There are some other harness length differences, but everything does plug up, it's just a little more stretched than it was before. If I have to use the 5s ecu, I wonder how that would affect the transmission part of this car given that it's an automatic and I think the ECU has a hand in controlling that mess. All unknowns, nothing unsolvable I don't think though. Curious that the 3sfe would have a crank and cam position sensor however.... unexpected.
