more importantly though, torque is what put stresses in gears over power for the most part... those F2Ts make crazy torque!
Yeah the torque figure from that car is insane. H-type gearboxes are known for stripping 3rd gear, most people just replace it with a PAR gear and nothing else breaks. But this car stripped 4th gear, Ive never seen a h-type do that before. It does run full slicks at the drags thought, runs 11.4 @ 121 with a standard engine, just heaps of boost

With all the revision he did on the LSD, welded the pin, welded the LSD etc, it didn't give up and was removed after 10,000 km's because he got his car back to stock for selling.

Thats was his setup:
-Holset hy35
-pushing 350 hp
-Mazdaspeed LSD v3
-Updated 3rd 4th shift fork
-Competition Stage 3 Kevlar Clutch


I'll get some more infos from him and let you know.
there you go! that's proof that the mazdaspeed LSD is plenty strong... too many naysayers here saying it's crap and want to spend more on the mfactory instead!

Definitely true, your shaft will give up first before the mazdaspeed LSD.

If this didn't break with 350 HP ATW, how much will you will push the 2.0L FSDE Engine?

The Man, have a look below at the welding, i managed to clean a bit of the oil with ACETONE and took a couple of photos :

welds looks fine!

there's this bloke in spain who pushed close to 400hp with a welded mazdaspeed LSD and stock cyrotreated gears before the gears gave way... plus a multitude of other things went wrong with his engine because he didn't spec out and tune his car right

Thats why am sure my Mazdaspeed LSD should be able to handle some big HP and sometime doesn't want to sell it.

Also its already modded for protege speedo.

By the way TheMaN what do you think of Signature Cans PCV valve delete kit?

are they useful?

Depends on how you use the MS one. I broke the friction/spring clutchs in one.
My Quife - is still alive. And my Guru is still good both. drive shafts in total on only 200HP at the wheel F2t and FGE DOHC N/A. Oh and stripped a ring gear or two.

No slicks either, Just Daily Burnout Routine into traffic.

Stock gearbox, never opened, stock engine and nothing broken so far.

On a low torque BP or FS the MS diff would be fine, but on a high powered FE3 or F2T it would be living on borrowed timed.

Well Mine was new only a few year old too. So I don't know version what but I don't think it was a Version 1 - still haven't fully pulled it might of been clutch pack in peices not sure - don't care either. Because it stopped locking up after 5000km's. Or should I say 3 months. did one driveshaft in that time.

Yes Daily burnout - even pulled out into traffic last night - right in front of a Blue SS - HP car. Not that they do anything in my area, A station wagon does not make screach sounds in traffic - it's that lowered Sp20 or Mazda 3 that gets pulled.LOL

you'll never know what you have unless you remember/kept track of which part number your diff was
