> w58’s in the long run just wont hold up under high horsepower applications, hence why they used w58’s in na mk3’s,and r154’s in turbo mk3’s. yea you can run it on a turbo 7m/2j/1j etc, but put in comparison with an r154 it wont hold up as long, when i put on that 60 trim, im probably just gonna tune it around 15pounds, i dont wanna run higher than that until i tear into my block more, as its already starting to show signs of weakness

I’m not argueing that it’s the weaker of the 2 transmissions. I’m just saying that I think some people underestimate the power they can hold. I’m not saying it will last forever.
