Adaptive suspension isn’t necessary or part of an engine swap so I don’t see why that matters (although a Tein kit is like 5lbs). BBKs are lighter than stock, and aluminum chassis stiffening is a matter of tens of pounds, not hundreds. Even being conservative you’re looking at 400-500lbs lighter of car, assuming you don’t strip weight elsewhere (battery, seats, etc).

You’re not getting something for free, you’re building a purpose built racecar or “racecar” or hotrod or drift missile or whatever you want to call it, instead of a pseudo-luxury sportscoupe. The “cost” is in that you’ll have a loud, rarely, harsh racecar instead of a car you can drive to work every day.
On some B58s it has a manifold. The engine has an intake manifold with an integrated water to air intercooler and an intercooler up front. It has a turbo system with more actuators and sensors than the FA20. It has a larger radiator. The transmission is larger. It has two extra cylinders. I can’t imagine saving 80lbs of weight with this swap.

The point about the adaptive suspension, active diff, stiffer chassis, etc is that the Supra has better components which is why it is heavier and is why it has more value. Again, by the time someone completes the swap, they may end up wishing their Supra clone was just an actual Supra, especially after spending Supra money and having less quality parts.

Like I said below, I agree with you that a racecar is the most logical application for this setup. Also, it could be cheaper trying to make the 86 more powerful with this swap than trying to make the Supra lighter. It would be hard to remove sound deadening; it would be hard to remove and sell the adaptive suspension system in order to install static compression; it would be hard to remove thickness from the subframe or suspension components to match that of the 86; it would be harder to remove quality from the interior without a full strip; it would take more effort to swap to a smaller brake setup to match the 86. I agree that this swap is most logical/cost-reasonable as a racecar likely using a used, higher mileage 86 along with a basic ECU package just to get the car running.

M140/240 comes in manual here. Probably not as good as the OEM in terms of feel but it's OK and obviously designed for the torque. Probably similar in length on those platforms too. Would need a little research.
Yea, if you are disgusted with the looks of the Supra and enamored that much with the 86 then the swap makes sense. Selling your car and putting that money plus the $20-25k in swap cash towards a different used car could get something better or worse, depending on your tastes. Subjectivity does play a hand in these decisions.

On the manual transmission, like I said earlier, that is one of the best advantages here. The engine and transmission could be bought as one assembly. With the 2JZ, the CD009 and adapter kit is another large expense. With the Pure Auto K24 swap, there is a need to source a S2000 tranny and an adapter kit. Usually an engine and transmission joined together are cheaper and less headache.

UZ is one that I've been tempted by but we don't get many V8 Toyotas/Lexus here so again, not that cheap and need work to make similar power. LS just isn't an option here, we don't get any of the models that use them so you either have to get one imported or from an imported car, so guess what, they aren't cheap.
Sorry, didn't realize you from the UK until after my post.The swap starts to make more sense on that side of the pond. I say go for it!

600whp with bolt-ons and a tune on race gas.

Shit, 400whp with a tune and exhaust on pump fuel is plenty for this car and cake for a B58 to make.
And if you can cross your i's and dot your t's you can even keep it street legal in California.

After a quick search I can't find much info on ECUs but I don't think that the M150 can run the DIs that the B58 uses. I suspect that the N55 uses similar injectors and seems that the M142 is used, but then I'm not sure you can get the factory accessory compatibility that you get with the M150.

As a racecar, this swap makes sense, but not as a full canbus daily; by the end of the swap, someone would likely drop Supra money into a car with less quality, less stiffness with weaker and cheaper components, etc. That just seems silly, but if someone wants to burn cash on a project then more power to them.

An LS swap with full can integration will cost more than just buying a C5 Z06...

The FA20 also has twice as many heads and cams. These boxers are VERY heavy for all aluminum 4 cylinders.


According to published weights I can find, the FA20 engine and transmission is 480lbs. The B58 is 306lbs and the ZF 8HP is 192lbs (498lbs combined). Not lighter than the FA20 driveline, but also a completely negligible weight gain for the performance difference.
