Yes the engine is a Subaru EJ/FB based flat four. However, Mr.Tada has informed me that the FT86/FRS engine has been revised by Toyota and Yamaha and will feature new block, rods, pistons, and head specification as well as Yamaha acoustically tuned exhaust system(s). This change is in effort of utilizing the state of tune to better fit the aftermarket compatibility, reliability, and most of all, ease of service as well as high revving, spirited naturally aspirated use in the character of FT86 (er, AE86)
It does use most of the software gear from Denso along with the GDI systems already in use by newest Subaru, but with a few surprises tucked in the control units that we cannot disclose yet.

ON the topic of LSD. This is something that is quite pricey and the types of Limited Slip differentials needed (and not needed) varies greatly by users that do require them. It could be an option as it is quite exensive part of the drivetrain.
A competition track user will require something a bit tougher than a 2 pinion or standard viscous unit. Traditional clutch pack 2 and 4 pinions will require high maintenance and custom settings for most serious users. A Torsen (tm) unit may be on the expensive side for a car to be very strictly focused on getting the price line low. We'll see how the packaging comes on the new car... It will almost be a necessity for most drivers who enter any form of motorsports, but for those that never need one, it will become another expensive part that a person will never see an advantage.
For serious racing though, an OEM unit usually suffers from lack of needed initial torque and final lock strength, and we usually always end up opting for a 4 pinion aftermarket systems, custom tuned to necessary settings.

The AWD system employs a compact, ultra-quiet transfer case equipped with a TORSEN® limited-slip differential (LSD) that is 30 percent lighter in size and weight than previous TORSEN systems.
LFA: The differential, by the way, is a Torsen limited-slip unit.
There's a pretty major performance upgrade on the 2010 Lexus IS-F: a torsen-type limited-slip rear differential. Previously, the IS-F only had a simulated limited-slip diff effect via its VDIM system.
The Torsen T-3 will be employed as the centre differential in all future non-Haldex Traction Audi models with quattro four-wheel drive, current applications: 2008 Audi S4 (B7), Audi RS4 (B7), and Audi Q7. Alfa Romeo uses Torsen C twin differential in Alfa Romeo 156 Crosswagon Q4 and then in 159, Brera and Spider Q4 models. Also Toyota uses a Torsen T-3 in the center differential of the Toyota 4Runner and Lexus GX470, with manual locking feature, and GM has a Torsen T-3 centre differential in the (non rear drive) Chevrolet TrailBlazer SS.
2012 S6, S7, S8 - Other new developments include a reworked Torsen four-wheel drive system, which, like that of the S8, features a self-locking centre differential.

Toyoda Machine Works Ltd., in 2003, purchased the worldwide Torsen division from Robert Bosch / Zexel Corporation. Zexel Torsen, Inc. was then renamed Toyoda-Koki Automotive Torsen North America Inc. to reflect this change. The company name change became effective on September 1, 2003.

production version looks amazing... make sure you understand that this is accessories catalogue so hence some of the unnecessary bling. Also if you didnt know, Japanese preffer to pick their own radio so a lot of cars come without them in Japan (most Toyota's do).
