I had a test drive with that seller's MR2 today, and it was really fun.

I am still wary of this though, as it is neither unique or my own project, since the 3S-GTE was swapped by a previous owner. There's something about buying someone else's project car that doesn't sit right with me.

Besides, a MR2 will attract attention no matter what...
Have it looked over completely if you don't trust yourself to vet it properly. The old rule of "never buy someone else's project" has very few exceptions...

As a second year, I can't attest to how bagged the tranny is. It seemed to pull fine during the test drive, but that's uber short term. There were no oil leaks that I could see. Clutch was sticky, stock steering wheel was long gone, and interior trim was like slighyly trashed, butt not TOO bad.

Exhaust has a hole in int which the owner disclosed no problem.

I can fix or have most of these minor issues fixed, my main dilemma is that it's a MR2, and not a sleeper.

Also no power windows and no air conditioning. Alsopower steering is busted. lol It that worth it? :lol:

I am tempted, but also want to pass in favor of my original sleeper idea

One local shop in Edmonton already gave me a ballpark estimate of 15K to 20K in CAD. For the 3S-GTE swap.

How much aftermarket support is there for a 1MZFE anyways? It's another option I am considering.
Even MR2s that came with 3SGTEs crave V6 power! check this build:

SC and Turbo! They took some wrong turns on the way, ended up getting rid of wire cylinder o-rings, copper HG etc.

I am going to pass on the MR2. The overall condition of the vehicle doesn't look like it should be worth $6000. 4K maybe and I'd buy it as a donor car.

That 240 above has a GTO powertrain in it (but ugh, auto)...just buy an updated GTO with the 400 HP motor then swap a 1MZ into it. Put the 400 HP LS into the donor Camry and voila, you have two sleepers! Of different sorts

Found a guy tonight through a local car group that has done tons of Toyota swaps. He's quoted me parts and all 8 grand for the 3S swap. Even less for a turbo 1MZ. 12Gs for a 1JZ swap!

AWD and V6 are NOT compatible - the block and transfer case will interfere with each other, not to mention the exhaust headers.
So will a E153 auto tranny from a Solara / V6Camry work on a 3SGTE engine from a AWD Caldina or alltrac Celica?

Yup, will bolt right up, stock flywheel and clutch, shifter cables (I have my 5spd swap parts for sale if you're interested). You'll need to figure out the situation with the axles though: stock V6 driver's side axle should pop right in, but passenger side requires a carrier bearing support, so you'll need to figure that out (possibly custom make one) as it is also part of the engine mount on a Camry platform.

Will the ttransmission from the Caldina work in a Camry platform as well? Or is the V6 tranny an easier match?
I believe Caldina tranny is AWD, no? You can convert an AWD tranny to FWD but you will pretty much need a FWD tranny for parts (diff, block off cover), so it makes no sense not to use said donor tranny as is unless it's trashed or something.


Generally, 3S blocks are found with E-series trannies, and 5S blocks are with S-series. The flywheel pattern on 3S and 5S is different, and so is the input shaft and clutch on S and E series boxes, so it's easiest to mate 3S block to E tranny and S-series tranny to 5S block. 3S block to S-tranny is possible, but need aftermarket flywheel and/or customized clutch configuration (you can research more on 3SGTE swaps into NA MR2s for answers on this combo).

Is ther an auto version of the E153? Or is that an entirely different series of trannys?

Also besides the vast amount of info you have already given on this subject :bowdown:, is there anything else we need to know about in advance?

Please provide some links as well in case I've missed them in the forum.

Ya, the A541 or whatever V6 Camry's run on. Good for 300hp, probably more. The catch is that the tranny is controlled by the Engine Control Unit, so you'll need to get an auto 3SGTE ECU and a transmission that will work with it. I do not know if a regular FWD A541 is going to play ball with just any 3SGTE ECT (Electronically Controlled Transmission, vs M/T for Manual Tranny) ECU. It may, it may not, I just don't know. Perhaps check the wiring diagram at least. Otherwise you'll need a tranny that works with the particular gen 3SGTE ECU you go with, and I don't know if there are any that are FWD and not AWD. Can you convert that auto tranny to FWD? Maybe, but you're really far into the uncharted territory by that point in time.

Yeah I just got back from one shop, and the techs told me that a 5-speed conversion with a E153 would be way easier, and cheaper. So In addition to eh engine swap, I'm also converting it to manual!

Whoop 5-speed turbo fun it is.

Personal experience with a Quaife in my Viggen...works well, but yes, it's more clunky in bad weather (which I don't encounter too often here in inland CA). It's almost like it doesn't ease in, not as predictable as clutch- or viscous-type LSDs

UPDATE

Bought a 4th Gen 3S-GTE from a JDM Caldina today.

It should arrive within a week or two. Now the wait begins...

I've learned that the s54 and s51 trannys are too weak to withstand boost.

So, what other transmission other than a E153 would work on this swap?

We're having a heck of a time finding a V6 stick shift Camry donor car. :surprise:

What would need to be done to a MR2 version E153 tranny to make it fit? @slavie ?

That depends on how much boost you intend to run and your intended driving style. Plenty of MR2 guys with 250hp 4th Gen 3SGTE swaps mated to S54 boxes run around without issues.
If you put a set of slicks on, launch the car at every light, and bang shift at redline then yes, S54 will be much easier to blow the gears with than E153.


You would need the shift selector mechanism with corresponding block off plates and mounting brackets to convert a RWD E153 box into a FWD one. Finding said parts may prove to be even more difficult than finding the FWD box itself, unless you find an MR2 guy that had to go the other way and has the parts.
