This is correct. The clutch packs on the M active differential can generate a lot of heat if they are constantly engaging and disengaging. I’ve put a Z4M in limp mode a few times this way with the earlier clutch-style LSD (E46 M3's did not share the same differential), quite the butt puckering moment...

Height regulations; even the 930's had to be raised from the torsion bar links for the US market to meet standards at the time, but mainly for bumper height as well as lights. Hence partly why the OEM suspension is height adjustable on those air cooled models and people prefer the “euro height” look more.

The Supra press release has already indicated having a water cooled, integrated exhaust manifold which is particular only to the B58B30O1 shared on the Z4. The older B58's did not have that and a very different head design as a result. Worth checking out these leaked technical diagrams if you want to geek out even…

That or a gentleman’s agreement between the two to give the Z4 a market advantage since it was their design. It’d be a little embarrassing if you shared your technology with Toyota and they’re making similar or more power while costing $15k less.

The Supra and Z4 M40i share the same B58 mtoor (B58B30O1). The other version you’re referring to is the B58B30M0. Jalopnik’s interview with Ben Haushalter also states it’s exactly the same but they’ve detuned it for “chassis balance”. Peak numbers on turbocharged vehicles are widely variable to some extent.

This specific car probably isn’t for sale, but this is generally exactly how they come off production.  Registering part numbers and creating a database specifically for the Supra costs a lot more money and adds more logistics for each corporation in terms of database and distribution/storing. They also have to be…

Seems more like a gimmick to get customers in the showroom. If they persuade a dozen or so clients who come to see this Supra to buy another premium car or a new Supra, then they’ve made out fine with their investment. They’ll keep it there as a show piece and a way to siphon business.  Posting it at that price only…

To some degree, yes I totally agree. But when it’s to the point of having unpredictable corner entries and braking points with other drivers around you doing triple digit speeds, then they need to be driving something that’s easier to learn from and think about a manual for their next track car. You can safely learn…

These are usually the same people I see at trackdays who nail it on the straights and then you hear them fumbling downshifts trying to find the right gear and miss apexes because they can’t heel-and-toe.

I used to ride a copy of this version to work and put some sticky Pirelli’s on it and could hit 50 mph. Round-a-bouts were a blast. Actually kept my skills honed really well when I used to race my motorcycle on the weekends. If you can’t have fun on a 150cc scooter then it’s the rider, not the vehicle.

Surely someone has a wagon older than my old gal?

Not to mention the ‘84 SC RS is one of the rarest 911's. Only 20 manufactured to meet FIA’s homologation and weighed just over 2,100 lbs with 290 hp.

I bought myself Raceware headstuds for the rebuild on my 3.2 Carrera. The first of a deep money pit...

I’d be more interested in the torque numbers than peak HP. Hybrid motors make a lot more usable power at very low rpm’s and relatively flat torque curves throughout the rpm range. The gripe I always had driving the XT’s were how the power jumped in at around 2k and quickly faded off with little top end power. I have…

Eh, that’s relative to some enthusiasts though. Lots of newer cars with similar mileage in that market but they’ll continue depreciating. My brother bought a Z4M 10 years ago and it hasn’t lost any estimated value since.

I’ve been working on B5 S4's for 15 years now. If you can’t wrench or know the basics of a 2.7t then you shouldn’t even be looking at those cars. If it was a manual, then I’d assume it was because of a 1st-2nd synchro starting to shit itself (had people try to pull the same on me during test drives).

But the same kind…

Keep it stock and remember you’re not Ken Block and you’ll never have those problems.

I loved my 2011 hatchback and never understood the appeal of the 2011+ sedan models. It was incredibly practical and I often loaded it up with trackday equipment and towed my motorcycle behind.

Those are EGT sensors (O2 is on the top) and it’s on a mock-up catalytic converter for dyno testing and measuring heat transfer.

It’s growing on me in the last day or so, especially the “pause” light. Only thing I have a gripe about is all the black on the lower bumpers.  I would prefer if it was painted the same as the chassis in some areas (warning: shitty photoshop to get a rough idea across)...
