hey neox / Mazdaspeed2oo35 i was told a few days ago on another forum that upgrading the turbo on the msp can destroy the stock tranny is that true?
Well you really need to do some work to your transmission in order not to break it with stock turbo or bigger one.. this is what i have done to my transmission and basically is holding what ever I'am trowing at it. It also depends how you drive your car, driving habits and how you treat it, I don't race my car everyday, i don't slam gears and i do periodic maintenance using good products.
* Complete transmission internals cryo treated.
* Fidanza 7.5 lbs flywheel.
* DSS Level-2 drive axles.
* ACT street performance clutch.
* ACT extreme pressure plate.
* Welded LSD front and back of it with cryo treatment.
* stronger synchros with cryo treatment.
* TBK Performance custom 600whp 3rd, 4th, gears with cryo treatment.
* Techa-Fit clutch line.
* Redline shockproof synchromesh heavy-duty transmission synthetic oil.
* TWM short throw shifter.
* TWM shifter bushings.
* CorkSport Bronze Oil Bushings.
No problems so far with my Transmission, but either way i'm going to knock on wood !!!!
