It is definitely an S-series trans (S51 / S54). Not the factory LSD either. There is a small chance that it is an aftermarket LSD. It would be good to know what car it came out of and the history of the trans. It was obviously in an older car (say, pre '94 Celica or pre '92 Camry or something) due to the cable speedo drive.

-Charlie

First couple things shipped...

Transmission is pending.

Bump for the other parts!

-Charlie

I'll be using it, sorry.

Also, Lots of interest on the transmission - any locals interested before I go through the hassle of shipping?

-Charlie

I have an extra stock ST205 radiator (replaced with a KOYO). I'm in California, so shipping may be a killer. Let me know.

-Charlie

I have a bunch of parts I will not be using on my BEAMS swap (into an '88 Camry Alltrac), including the transmission, shift cables, axles, 2-pot front brakes, Superstrut front suspension/subframe, etc. This is all from the standard "<50k mile" engine set from an SS-III BEAMS Celica- looking under the oil cap seems to confirm the low-miles assertion. All parts are located in Pasadena, CA. Pickup highly preferred for all the heavy parts. Buyer pays shipping.

Here's the main stuff:
S54 helical LSD transmission:




$500 OBO

2-pot front brakes:



$200 OBO

S-series trans shift cables: SOLD

BEAMS front axles (beefier than 5s axles): $150 (good shape!, sorry no pics yet)

Since I am only using the motor related parts and wiring harness, anything else that might be found on here that you might want (and not already listed) is also available:

Let me know if you want anything (super strut suspension, subframe, AC compressor, etc.) and we can negotiate.

I also have a stock ST205 radiator from my last swap (ST205 motor into '89 Camry Alltrac) that is in good shape if anyone is interested...

-Charlie

I've run my gen3 3s-gte on California 91 octane for 10k+ miles at 14psi of boost. It hesitates a bit here and there (knock sensor controling timing), but it hasn't thrown any codes for that. When I go to the track, I put in some 100 octane to get it up to the 94/95 octane range and it runs great at 17psi, just under boost cut.

-Charlie

PS. GEpower, octane is rated differently in the US than most other coutries. Our 93 octane is pretty similar to your 98 octane. Some places in the US only get 91 octane max though, which can cause problems with JDM motors.

You probably already know this... but make sure it is a V6 Solara trans, not the 4-cyl trans...

-Charlie

Is there any chance that the temp sender or wiring is bad? Could you test it out in a cup of boiling water and 'room temperature' water? I would imagine if you are seeing 220*+ oil temps all the time that might be the case.

-Charlie

My '90 4-cyl 5-speed Camry (before the swap) was around 3100rpm at 80mph. I'm not sure if this was a final drive difference or a 5th gear difference. Very nice for getting good highway mileage - I used to get 35mpg+ on road trips at 70mph.


Oh yeah, the axles! That's yet another issue. I was lucky to be able to use factory V6 axles on my Camry, but I still had the pain of finding the correct axle carrier.

-Charlie

The water neck, wiring harness, accessory brackets and other parts are different between the Celica GT4 and MR2 Turbo. If you are stuck on getting a motor set, make sure you go with a Celica motor set. And make sure you get all the parts. I would still highly suggest you get a clip.

To use an MR2 transmission, you will also need to convert the shift cables/brakets to FWD (they attach on opposite sides of the transmission).... it is not just a plug-n-play operation.

-Charlie

I used a '95 GT4 front clip that came with body panels, brakes and rear subframe/diff. Any parts you don't use can be sold to the highest bidder, and you have a great blueprint for how everything should be installed in your car.

-Charlie

Since you already have everything there in your car, you can just replace the pump itself with a 1/2 watt or 1 watt 1k ohm resistor. The other parts shown in the schematic above are already in place in your car...

-Charlie

If you are using a cross-flow front heat exchanger, the 3-core intercooler could help you with water hose routing - wait, are you keeping it a top mount?

-Charlie

Not quite. A USDM MR2 94/95 MAP sensor is a gen2 (ie, incorrect). A '94+ JDM or other market 3s-gte MAP sensor should work.

-Charlie

Isn't all the information right here?

http://www.6gc.net/forums/index.php?showtopic=29705

What am I missing? There are a ton of different types of Celicas and options for turbocharging. Different threads in that list will apply to different people...

-Charlie

There is a post on celicatech where someone started with an ST185 Alltrac and put in a V6... Go search for it (it is in the stickies in one of the sub forums). Then, add the difficulty of putting the AWD rearend in your Celica...

-Charlie

E56 axles (full with the carrier bearing) woult be perfect for a 6gc with an E153. Almost all of the E-series transmission stuff is interchangable. The problem is finding those axles in the US...

-Charlie

The stock ST205 motor in FWD with an LSD (my setup) is already too much. You can spin the tires in second (yes, both tires and yes, they are sticky) with just intake, exhaust and boost controller...

On the other hand, I understand wanting to work reasonably within the law...

-Charlie

Have you checked prices on the OEM wires at your dealer? The '93 Alltrac wires should work (though, you may have to fit them in the plastic case on the valve cover). I'm about ready to refresh my 3rd gen ignition system again... let us know how it goes.

-Charlie

Just in case, you should check the P/N of the MAP sensor on MR2OC to see if it is a 2nd or 3rd gen sensor.

-Charlie

Yeah, the vid sounded like ignition problems... And the 3rd gen motor uses a 2.5ish bar MAP sensor.

If the motor runs fine most of the time, the MAP sensor is probably correct.

-Charlie

That's not a torque bar that you see there, it is just a motor mount stiffener. It just goes from the alternator bracket to the top of the engine mount (on the motor side, not the chassis side). It wouldn't aid in grounding...

That said, the ground strap on that side of the motor is really important. I'd connect that point to the chassis (not on the strut tower, use one of the bolts for the power steering reservior). The most important ground is on the back of the intake manifold. An extra ground wire there might also help out.

-Charlie

You will need to repack the inner CV with grease. It should be included with the axle that you receive.

-Charlie

Just so you are clear, the 'inner' axles are the part that actually goes into the transmission. It is just a solid stub. The 'outer' axles is the rest of it, where it goes into the hub, the outer CV, the axle and the inner CV. The inners and outers bolt together with those 6 hex-head bolts. Watch out when you unbolt them so you don't drop grease all over the place.

The left and right outer axles are the same for the ST185 and early Camry V6. The only thing you have to worry about is ABS or non-ABS (and ABS axles work in a non-ABS car, just not the other way around).

-Charlie

The electrical load issue might also be the "ELS" connection to the ECU. It tells the ECU when you are using the headlights, rear defroster, etc... but it shouldn't make a huge difference. Go look for grounds and other wiring problems first.

(on my 3rd gen motor, the ELS connection changes the idle from 700rpm up to 750 to deal with the extra load)
