Transmission Strength Comparison - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

Wes B. · 05-05-2013, 11:05 PM

As the aftermarket continues to expand for the GT86/FR-S/BRZ, the yearn for more power is continually sought by owners. As a curious owner speculating on twin turbo'ing his FR-S, I am wondering which transmission is more capable of reliably putting down 300+ ft-lbs of torque: the current Aisin-Warner AZ6 or a Toyota W55 from a 2002-2005 Lexus IS300? I remember, back in the early 2000's, that Toyota was considering the Aisin AZ6 for their 2002 Lexus IS300, but the engineers deemed it too weak to handle the 218 ft-lbs of torque produced by the 2JZ-GE. Instead, Toyota used the W55 because it was deemed more apt to handle the 2JZ-GE's power.

Also, would a Tremec T-56 or TR-6060 swap be even remotely feasible?

Hard to find and wicked expensive for a heavily used one. Any other alternatives?

I haven't heard of anyone damaging the Aisin yet.

Neither have I, but I was simply thinking about how to keep the car running as long as possible with a more potent powerplant.

How much power has the AZ6 withstood behind a built SR20DET? Anyone know?

Not that high I assume(500sh) because people would get them fixed every now and then.

I'm wondering why someone would TT a 2.0 flat 4... or any 4 cyl in general?

Twin 15mm turbos in a parallel setup set to 9 psi would create the perfect amount of power, and it would give the engine the low-end torque that it's lacking. Plus, it would look sick!
