Rocket Bunny BRZ Makes Do With a 6.2-Liter LS3
By Brett Foote

Toyota and Subaru's rear-drive coupe is an amazing little car, with one caveat - it doesn't pack much punch. But like everything else in life, an LS makes them infinitely better!

 

I was blown away by the mere 2# difference in drivetrain weights! NO balance issues!

 

I’ve actually scaled the LS3 components - and if you read the Speedhunters version of this article - seems lifted almost word for word - it says the weight diff in drivetrains is 44 lbs. I don’t believe 2# or 44#. T56 alone weighs a good 55 lbs more than a T5 - it and the MUCH bigger bell, flywheel, clutch weigh at least 50-60 lbs more than the brz components. And all aluminum 4 banger vs V8 - the V8 is gonna be at least 75 lbs more. Similarly equipped, LS3 is only 18 lbs lighter than a cast iron Ford 5.0L w/alum heads. Don’t know where their numbers come from - maybe they reduced weight in other areas (unlikely given MUCH bigger wheel/tire package) - but no way LS3/six-speed is only 2 or 44 pounds heavier than stock flat 4/6 speed.

 

Michael, your report above makes MUCH more sense! I was thinking, NO WAY, but OK, if they say so.... I think you are right.

 

Nice swap!!! I have a question tho I hope you don't mind answering:




For the original FA20's Transmission from the BRZ/86, whats the length of A in this picture? If you are using a T56 transmission for the swap, which specific one did you use to make the shifter fit right at the OEM location?

 

lol that contrnt curator did not build anything, they just post clickbait like this to get views and revenue for the forum.
