Supercharged GT 86/FR-S/86 vs. Turbocharged BRZ

[WolfpackS2k]

What part of that doesn't make sense?

-The 370Z's engine runs extremely hot and track use is not recommended without an aftermarket oil cooler. And even then keep an eye on the temp gauge.
-The brakes overheat...quickly.

These issues are well documented online. Nissan laid an egg this time around with their sports car.

The trick is to be able to stay behind it for 5-6 laps.

Toyota doesn't want turbo - yes

Never said anything about superchargers

Akio Toyoda wants a car that has quick throttle response and doesn't lag to spool up like turbo kinda does.

Having owned an 04 Cobra (factory SC) and driven many turbo cars over the years I'd definitely suggest a supercharger. While a turbo will get you better MPGs and more than likely make greater power, for cruising on the streets there's nothing better then the instant torque of a supercharger. Turbos have too much lag for street driving IMO (for basic mass produced cars).

Anyways, not trying to get a SC vs TC war going or anything, JMO. I actually prefer turbos in terms of efficiency, but I think SCs are a bit more fun...

Btw... talking about twin screws and roots style, not centrifugal

Even though I've always been someone who prefers turbo charging and have already theorised what could work with this engine I'm thinking a super charger would be more fitting with this type of car or at least for the 86.

Why? Personal opinion I guess but when I look at the 86 I look at it as a slightly heavier Exige. Funnily enough it is also supercharged with 264hp in the 2009 model and after driving one of those it was tough to beat. The power delivery is so smooth it almost feels like a NA car, the throttle response is instant and I mean instant. The minute you step on the pedal it goes. I think this is why Toyota have decided to take this route amongst other reasons.

Turbo will always have lag. It can be spooled quick but never responsive at the level of N/A engine. For finer driving techniques, this makes a big difference.

[Boxer 86]

I wan't mine to be turbocharged. If it comes with nothing but NA, then a turbo swap will happen. All forged and lightweight internals, higher lift/duration cams, lower compression pistons, H-beam rods, and flowing the nicely forced air will be a BorgWarner unit to some form of titanium exhaust.

I love japanese cars, and love nothing more than STOMPING on the average american's dream of a raw-hide muscle car that is better than anything (in their mind).

^LOL, good luck with that my friend. Have fun spending $20k in modifications to hang with a Mustang GT 5.0

That is not my goal with this car, that is just an 'aspiration' if you will. That particular goal will be carried out when I do a 20BT swap into the FC.

My goal for this car will be either autocross or a mid-level time attack class racer in Redline Time Attack. The track is this cars true proving gorund and I intend to keep it there. But it needs to remain streetable. Out-and-out track cars are fun, no doubt there, but for it to comply with my vision it needs to still be usable on the street, otherwise what's the fun?

My honest guess is the supercharger will only be sold as a seperate trim level with a lower compression ratio motor.

Not only that, but could the internals even handle a bolt on SC? I'm more familiar with a turbo set-up, so I'm used to seeing the internals having to be swapped in favor of stronger forged items, and since boost is essentially boost, wouldn't you need to go with forged internals with a SC too?

i was reading the links and it said if if they offer a supercharger its going t obe like the tacoma well TRD does offer a suppercharger and we'll have to buy it separat! I would like it as an option like a GPS or something...

Does this engine have forged internals?

I don't think a drop in compression will be required at all. Look at the Lotus Exige S260. It uses a 2ZZ-GE with 11.5:1 CR, standard port injection and is boosted to about 8psi via a supercharger.
A lot of people miss the advantage of running direct injection, they just see it as an inconvenience to tuning. I see it as an advantage. You can get away with things you just couldn't with port injection.

No.

Twin charged, with water and nitrous oxide injection...
