The Lexus IS F features a 5.0 L direct-injected 2UR-GSE V8 producing 416 SAE hp (423 PS, 311 kW) at 6600 rpm, while peak torque is 371 ft·lbf (503 N·m) at 5200 rpm.

The Lexus IS F features an 8-speed Sport Direct Shift (SPDS) automatic transmission with sequential shift which can lock-up the torque converter from 2nd through 8th gears (see also: Lexus IS transmission specifications). The SPDS is derived from the unit introduced in the 2007 Lexus LS, which was the first vehicle to carry an 8-speed transmission.[34] The SPDS allows for shifts to occur in 0.1 s (100 ms),[35] compared to 0.05 s (50 ms) of F1 race cars.[36] The wheel-mounted paddle shifters allow for gear shifting while steering, and a manual mode can be selected for added control. The 8-speed transmission also improves fuel economy,[37] with lower overall consumption than BMW, Mercedes, and Audi rivals,[35][37] and avoidance of the U.S. Gas Guzzler Tax.[38]

Thanks for posting this. I remember reading this previously but i couldn't find it.

I think the transmission will hold up just fine adding power to it. If it can handle the IS-F, it should be able to handle a modified FR-S. Right?

I believe so. There is a twin-turbo IS-F on YouTube with the turbos mounted in the rear bumper at the exhaust, from what I remember reading, he didn't have any transmission upgrades.

I'm leaning towards NA > SC > Turbo in that order but this looks like a pretty ingenious setup. Love the bolt-on-ness of it.

Its almost right after. There is a pipe, but its short enough to not really make a difference IMO

How about we make a pact that we leave Don alone until he posts something after the testing. I'm sure he has his hands full and believe me no one wants to know the results or post them more than him. He's on top of it!!!

I think you two are missing the fact that this isn't an IS-F which was designed to start at 500hp. This is a much smaller car with less than half the power. I still do hope that it can take an extra bit of hp though.

The auto sounds very strong but the manual box sounds more limited though.

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?

what are you saying? you dont think the trans will be able to handle a turbo on an FRS? despite the information sierra posted?

I don't know if it has been discussed yet but how much do we know the manual tranny can handle, leaving clutch out. Also what CAN the stock clutch handle?

I wonder if a t56 would fit up nicely inside my frs
