e153 vs S54/S51 Hybrid....., can we make the s54 stronger..? Options

[njccmd2002]

was reading in mr2 this, making a hybrid S54/S51. Using the internals from a camry tranny into ours. in the case that e153 is difficult to find or get.

he S54 housing with S51 internals gives you great gear ratios (similar to the E153) without the added weight.

i dont know much about the different transmissions, but isnt the LSD the whole point of getting the e153 transmission?

The main reason is gearing a bonus is the mr2 version has the LSD
nj, which camry? Years ect.

[njccmd2002]

let me go find that post, thye were talking about same gearing. except the lsd. the beauty is no axle modification.

reading more an more they were talking about a v6 swap...

from their website

I don't find the S54's ratios suitable for the 3VZ/1MZ unless it's solely a track car, but even then, the low top speed will handicap you on a track with long straights.

The E153's axles will bust before the internals break, so you're looking at 500hp+ with that. The S series is known to handle up to 260-275rwhp (supercharged 1MZ), but the differential and pinion gears will fail on hard launches with large racing spec tires.

Personally, I used an S51 because it has a gearset which is more suited to the torque curve of the 3VZ/1MZ even though it was used in conjunction with the Camry/Solara 5SFE.

I know you've studied the ratios, but here they are again.

S51 3.538 1.960 1.250 0.945 0.731 Diff: 3.944 (Camry/Solara I4 M/T)
S54 3.285 1.960 1.322 1.028 0.820 Diff: 3.944 (Euro spec)
S54 3.285 1.960 1.322 1.028 0.820 Diff: 4.176 (US/JDM spec)
E53 3.583 2.045 1.333 1.028 0.820 Diff: 3.625 (92-93 3VZ)
E153 3.230 1.913 1.258 0.918 0.731 Diff: 3.933 (97-01 Camry V6)
E153 3.230 1.913 1.258 0.918 0.731 Diff: 4.285 (91-95 MR2T)

The V6 E153 has the longest gearing of these transmission, while the 4.176 S54 has the shortest. The S51 is in between the MR2T E153 and the V6 E153 in terms of gearing, which is why I chose it over the S54.

In order of gearing, longest to shortest (by 4th and 5th drive ratios listed respectively):

E153 3.230 1.913 1.258 0.918 0.731 Diff: 3.933 (3.610, 2.875)
S51 3.538 1.960 1.250 0.945 0.731 Diff: 3.944 (3.727, 2.883)
E53 3.583 2.045 1.333 1.028 0.820 Diff: 3.625 (3.727, 2.972)
E153 3.230 1.913 1.258 0.918 0.731 Diff: 4.285 (3.933, 3.132)
S54 3.285 1.960 1.322 1.028 0.820 Diff: 3.944 (4.054, 3.234)
S54 3.285 1.960 1.322 1.028 0.820 Diff: 4.176 (4.293, 3.424)

AFAIK, Jim King and I are the ones using the S51 coupled with the 1MZ. The ratios seem well suited during my short drive, but 1st gear is really short and almost useless. It'll definitely be of no use with a supercharged 1MZ. Acceleration in 2nd and 3rd gears is good. 4th and 5th are pretty long cruising gears and keep the engine revs low, so that's a plus. I have a 2001 S51, so I have the double synchros on 2nd and 5th, and shift feel is positively good, but mine is rebuilt.

The S54/51 shares differential with the C series tranny, so the OEM helical LSD that was available on the Spyder (2004+) drops right into an S54/51 tranny. I have one in there now

Well, from my experience the s54 tranny doesn't like power over 300whp, Or possibly reving to 9k.
The s54 is tiny compared to the e153, I'd rather have the added weight (which isn't too drastic) than risk ripping gears apart.
That along with what has ben mentioned, the LSD and longer gears.

-E153 for double synchros (e153 has them on 2nd,3rd,5th... s54 don't have that)
without that you will blow you second gear or synchro, a common problem on 90-93s e153 who don't have that

-E153 has also an integrated oil pump to cool tranny oil and keep bearings lubrificated

-E153 clutch is much more bigger and stronger

-E153 isn't faster getting into gear....but it is shorter throw and it stays into gear firmly

-If you have 3sgte, LSD is a must and is even not enough to hold tires firmly on the ground in second gear at 15psi

[njccmd2002]

are they hard to get?

[bdub215]

and here i thought the E53 was geared taller then the E153. E153's AFAIK arent hard to get. i always hear (well read) about people getting them.

[Remy]

Finding one local will be hard.

I looked around for a s54 and an e153 at car-parts.com (local junkyards). the camry e153 is actually a lot easier to find than an s54

[supershannon77]

i no jdm engine depot has a few of the camry e153 and other toyota trans that they guy is letting go for pretty cheap jims going there on monday if u want him to check anything our for u.

How much for a camry 153?

[zeus83]

im still undecided whether to go E153 'n customize to fit my ST202/3SGTE or go S54 SS-III BEAMS with LSD...apparently both have LSD

from what i read here;

Option 1:
1.Get E153 Tranny
2.Get E154 tranny from ST205 GT4
3.Mix n match shifter cable, levers and axles
4.more heavy duty

Option 2:
1.Get S54 tranny from SS-III BEAMS
2.no mods required
3.is it heavy duty?

[Lazurus]

If you go with the 54/51 you can still have LSD. OEM helical LSD that was available on the Spyder (2004+) drops right into an S54/51 tranny.

Lazurus,

apart from the LSD, will the S54/51 be able to hold for long when mated to the 3SGTE motor?

[Lazurus]

I would contact the guys on mr2.com that are actually running that set up but I have found more than one person with 400+hp running that set up with over a year using that set up. It is the set up I am personally looking to run when I attempt to swap in the 3vz-fe.

def wanna look into that and see the good word on that lol

[njccmd2002]

Definetely a good points here.. I hate to mix and match axles. tough...
