mr2 lsd for 5sfe transmission?, got a whiff of this on the forums. details??? Options

[3sgteLuke]

so... i was bored and i was browsing teh forums and stumbled upon a mention of an 05 mr2 spyder lsd http://www.6gc.net/forums/index.php?showtopic=55683.

1.what do they mean by "not too agressive"

2.what are the set backs if a diff is too agressive?

3.could someone explain the advantages of helical/torsen? http://wikicars.org/en/Limited_slip_differential this gave me a general idea. is the mr2 a 1 , 1.5 , or 2 type lsd?

"The S series and C series transmissions share differentials:

The S51 (Camry, Solara), S53 (90-93 Celica), S54 (MR2, 93+ Celica), C56 (MR2 Spyder, Celica GT), and C59 (Corolla, Matrix, excl. XRS) all use the same differential. The MR2 Spyder's helical LSD WILL work in any of these transmissions. The differential part number is shared between these transmissions. Same part number = same part. The MR2 Spyder, however, was the only car to receive a factory LSD that is compatible with these transmissions. It should be exactly the same as the TRD Helical LSD that was discontinued for the S54."

4.does this mean that the transmission thats paired with my 5sfe is a s53? or a c56? by celica gt do they mean the 7th gen?

5. I would love someone who uses one of these to detail the handling difference with one of these installed. in detail

6. supposedly these are easy to install, true false?

7. can you tell this is reviving my interest in the celica?

8. Before this lsd revelation, what other options did one have when looking for lsd upgrades? excluding phantom

9. how would a 5s tranny paired up with an mr2 spyder lsd compare to a v6 tranny in terms of longevity, performance, and fit for application?

sorry for the explosion of questions but pleeez answer all of these, because this would seriously change my car for me.

Old news as i posted that link thread, in that thread a while back "http://www.6gc.net/forums/index.php?showtopic=47687&hl="

Ive been running this set up for over a year now

hybrid 3s/5s clutch from spec
s54 trans w/c56 helical lsd


I went with the helical/torsen because it was less aggressive meaning that amount of time the diff stays locked and the amount of throttle which the diff stays locked is different. I didn't want a 2 or 1.5 clutch type because they tend to lock up a bit more aggressively depending on throttle and the tightness of the clutch pack. Plus the clutch pack wear out a bit faster and i wanted something that would last.

be warned tho technically the torsen/helical diffs are only half LSD because both wheels need traction/resistance inorder for the LSD to lock up. So if one wheel is on the ground and the other is on the ice the diff will not lock up.... i recently got a cabin and went boarding up in bigbear and solved this problem of ice and the wheel not having traction on the trails i went on by applying the brake as i went forward... this supplied the resistance the diff needed to lock up and i was able to continue on the trail/sloped driveway.

I also didnt go with the e153 because i heard it was heavier and lifting the st205 trans proved that to me. I was already accustom to the gear ratio of the s54, i didnt want to have to play around with the shifter cable situation, and my power goals where not anything super high.

i have class soon so to answer ur other questions quickly

just because the trans share the diff doesnt mean the bellhousing have the same bolt pattern

the install of the diff takes some know how and special tools and dials if you have to ask u should probably take it to a specialist. I have the know how and have the tools but figured since i didnt have the time or super amount of experience id have it sent out..... I actually bought another trans so the swap didnt interfere with driving around town.

hope this helps
