For those of you who are looking forward to turbo or supercharge your BRZ / FR-S / GT 86 via the aftermarket, however, we must remind you of a crucial caveat that appears on the second photo of this article: “Medium Torque Capacity RWD 6-Speed Manual transmission (AZ6)”. A cursory glance at all the vehicles that have used the Aisin AZ6 reveals that the torquiest of the lot is the S15 Nissan Silvia Spec-R, producing 202 lb/ft. All other AZ6 users produced somewhere between 124 and 163 lb/ft of torque, with stock BRZ / FR-S / GT 86 rated at 151 lb/ft. Notably, when the North American market demanded a manual transmission option for the Lexus IS 300 and its 2JZ-GE 3-liter inline 6′s 218 lb/ft of torque, the Aisin AZ6 (or J160 in Toyotaspeak) was deemed to be too weak. Instead, a W55 variant of the W58 5-speed manual from the naturally-aspirated Toyota Supra and Lexus SC 300 was used. Thus, it’ll be quite interesting to see what Subaru and Toyota engineers would do for a possible future manual supercharged or turbocharged FT-86 variant. Further modifying the existing AZ6? Or doing so with the higher-capacity AY6 (which can reportedly handle over 345 lb/ft of torque)? Or reach out to Getrag as Toyota did for the 233/V160 when it needed a stout yet sporting 6-speed manual for the Mk4 Supra Twin Turbo?

The AZ6 Manual tranny is in several other good cars that can handle gobs more power, like the s2000, miata, and a dozen others that are known to go up to 500hp without issues.

If you only look at what power the tranny holds in stock power levels, you're missing a very large part of the equation.

On the other hand, several of the companies have modified the AZ6 to their own specifications, just as the BRZ/FR-S has. So that is another variable.

Im at work or id research this myself, but say this AZ6 just can't handle what we need it to due to the specs its built to, will those that have been in these cars you say can handle up to 500 or so drop in?
We also might have options to shot peen gears etc to beef it up a tiny bit without redoing the entire thing if it doesn't hold up.

Just because it is based off of another transmission doesn't mean it is the same transmission, which means that it can not be guaranteed to take the same abuse. It could be made with a different alloy for the gears. It could have smaller parts. It could...the list of variables goes on. What you two are saying is that if I design and build a plane based off of an F22 raptor, it will super cruise at mach 1.4. No it doesn't work like that, or else cheaper (cough*many made-in-China*cough) copies would be just as good as the originals. I never said it can't. I only said that no one knows until one breaks...

Just as Synack said.

Can we get off this reoccurring topic?

I haven't seen many 300+wtq miatas...
And while the s2000 uses the az6 it is almost completely redone by honda.
