The next gen Z!

b1adesofcha0s

There really aren't any credible sources confirming this. Look at the dates for the articles you're posting. That one there is from a year ago. More recent articles say that the BRZ STi is going to be N/A. Looks like the plans are to turbo charge that engine for use in the next gen WRX/STi, but not the BRZ.

2014 Subaru BRZ STI To Offer Up To 230 HP Sans Turbo: Report

One of them said that a turbo charged version of the BRZ's FA engine will be going into the new WRX/STi, but not in the BRZ itself.

The sources for the Cayman has not been confirmed, nor has a renowned automotive publisher said anything regarding this. It doesn't make sense that they would put a turbo 4 in another Porsche either. Noone will buy a 911 with a flat 4, noone will buy a Panamera with a flat 4, noone will buy a Cayanne with a flat 4, maybe if they offered a smaller SUV, but why would Porsche compete that low in the market?

I obviously like FI, as I'm having two superchargers being slapped on my car, I don't dispute that FI has done amazing things for the tuner market, so I agree with you guys on this. I just like seeing a confirmation from the automaker. Sometimes the things we ask for are terrible ideas. Thunderbird, Chevy SSR, PT Cruiser, Prowler (needed a V8), Aztek?!?, reinvented Cougar (thank God they euthanized it) I think we all can agree, anything that improves upon what we have today is a move in the right direction, regardless if they go NA or FI

Caveman, how is an inline 6 with turbo's lighter than a naturally aspirated V6 with no turbos? Displacement doesn't necessarily change the size of the motor. The physical size of the VQ hasn't changed, just it's displacement. Same with the LSx motors range from 5.3 all the way to 7 liters... physical dimensions are the same. Then you add the weight of the turbo's, intercooler, piping, strengthened components. It will not be lighter. 4 cylinder turbo motors don't save much weight over a V6. And to make an existing engine physically smaller, well that's pretty much impossible without redesigning it entirely.

I think you failed to read through this thread entirely. Not only that, your comparing an RX-8 of all things. It had a chassis specifically engineered for only one car, had a rotary that weighs very little, again used on only one car, and a drivetrain made to handle it's puny 159 lbft of torque. The RX-8 was an expensive vehicle to engineer. They did it out of passion, not because it made any sense. Remember that Renault is running Nissan, they won't even entertain the idea. From an engineering and bean counter standpoint, Nissan is not going to move the Z to a dedicated chassis. One thing Nissan can take from Mazda is their skyactive idea. Improve mileage from a combination of sources, which has been posted by myself and others multiple times.

I'm not attacking your idea's as if they are bad, it just doesn't work for this scenario.

I am no newby when it comes to engines but I appreicate where your coming from. Your argument is understandable BUT consider today's technology and the fact that I was implying a complete redesign for the engine. The VQ is not exactly on the weight loss plan especially when ancient pushrod technology like the LSx series motors with more displacement are coming in lighter. Now also consider that those motors were designed to allow for varrying displacement. You can only go so far due to the size/design of the block. I further realize turbo equipment will add weight to any engine bay but your talking about perhaps 30 to 40 lbs if done right. With that said if you build a physically small, efficient, light v or i 6 block and add a turbo I believe 1) if Nissan chooses they can make a smaller chasis 2) this design would be easier to cram against the firewall 3) displacement will be up to design and physical dimensions.

Actually, I did read this thread entirely and I saw a lot of bad ideas...Sorry. You missed my point entirely. The irony is that Mazda designed the Rx8 on a McDonalds budget. They only had a hand full of engineers and designers working on it. And you are 100% incorrect as that chasis was shared with the Miata. It is a streched Miata chasis. As far as the drivetrain...Let's see Tranny handles 400 to the wheels (ask the 3 rotor guys)...Drive shaft over 600 wHP...Rear end unknown...I know this because there is a crazy dude I know running a 3 rotor in my neck of the woods and that car was nuts...All being run off the Rx8 drivetrain. You are right though it was out of passion but id did make total sense just look at some of the NAtional Autocross champions and what they are driving Miata's and Rx8's to name a few. It's sales sucked because the engine tech just wasn't there.

As far as the Z going to a dedicated chasis your making assumptions on my part. I assume Nissan is going for a redesign here. They've already implied a smaller platform so I assume they will have a BRZ/FRS competitor with a Z badge and a stretched version of that platform for the Infinity G so I would say the G is going on a diet as well.

My point is that Mazda did something right...They engineered an amazing chasis capable of handling much more power then it came with. Nissan would be wise to pay such attention to detail in there chasis. Small/strong turbo 6 cyl as close to mid-engine layout as possible (attached to the firewall and low) and over engineered drivetrain.

They want to keep the BRZ below the new WRX/STi so they will not turbo it.

I think that cayman turbo rumor is being confused with the Porsche 961: Porsche 961 confirmed | Auto Express
They won't let the cayman be better than the 911, but they will let another in house mid engine coupe be better.
It seems Porsche is all about making a new model almost every year going into the future.
Whatever they do to the new Z, I would love it to be lighter.

The specs on the cayman turbo is only 350hp on a 2.4L turbo 4. The 911 is is a 3.8L turbo 6 rated @ 500hp. How would it be better? The article did say they'd be using the porsche turbo engine on multiple models so, your point is STRONGLY in the valid area.

RoshDawg

Oh I meant any Cayman being better than any 911. So a Cayman Turbo would certainly be better than the base 911, especially since the Cayman S is already so close to the performance of the base 911.
I just think it would be weird for Porsche to have a Cayman Turbo AND a 961. Then again I never would have thought Porsche would have an SUV, and now they're going to have 2, not to mention 2 different 4/5 door models (at least) as well.

Yeah but the base 911 is till 3.8litre 400N/A HP which can sustain power longer through the revs with way more continuous torque than a 2.4 l4. the 911 would still be a sub 4 second to 60mph car while the porsche cayman would get 4.4 sec to 60 ONLY with the sport chrono package. Without it, specs sound like a 4.7 to 4.9 sprint. The 911 went through "They cayman is better from 2007-2012" anyway. Many felt though the cayman was slower, it was a truer sports car. Regardless, the 911 is still considered legendary.

speedfreek

Regardless of this turbo nonsense for the likes of Porsche and Toybaru. I want a turbo'd Z next generation. Where is the speculation at on that? Where are the "credible" online sources fleshing this story out? This is insanity! I demand answers

Cayman S has a 3.4L flat 6, 325HP, 0-60 4.7s
Base 911 has a 3.4L flat 6, 350HP, 0-60 4.6s
Torque curves are about the same, as well as same redline.

Sorry for derailing this thread!

Lol my Honda prelude was faster than an rx8 that car was a joke compared to the s2000 and 350

cavemancan

Put it on a track with more then strait lines and you'd be wrong. The S2000 is the only car you mentioned that I cannot deny was faster in a strait line and on the track from factory but this is not relevant.

Not that it means all that much, but the rx-8 and 350z put down the same time on the Top Gear test track.
