Nissan is looking to turbochargers as a method to deliver high-output performance with low fuel-consumption in its future lineup of vehicles. Tetsuya Takahash, a top engineer at Nissan, made the exciting comments to the folks at MotorTrend.

While Nissan currently uses turbochargers in high performance vehicles like the GT-R, this new line of turbo cars would use turbochargers as a replacement for larger displacement engines. Most likely the first turbocharger powerplants would come to replace the 2.0-liter and smaller engines found in models like the Sentra and Versa.

Currently GM and Ford are looking to bring turbocharged four-cylinder engines (some as small as 1.4-liters) to market in an effort to meet increasingly stringent CAFE regulations.

But Takahash isn't just talking about the fuel misers, as there is a strong possibility that Nissan would look to turbochargers combined with a smaller V6 engine to replace aging (although impressive) engines like the VQ35 and VQ37, which power models like the 350Z/370Z and G35/G37. Takahash is quite familiar with high-performance turbocharged engines, having been a part of the team that developed the amazing SR20DET that powered the Nissan 240SX (Silvia) in Japan.

Will the next-generation Z be twin-turbocharged?

I wish they'd turbo the X! That would be sweet. I absolutely love the sound of a turbo spooling up. Guess it's time to get to work on my old 89 probe! I miss driving her so bad.

Xterra hines just got his X turbo'd. I'm excited to see how it runs

Thats all well and good, but remember:

There's no replacement for displacement!

:D

BAH! Boost IS the replacement for displacement.

I'm not gonna argue that boost certainly helps, but you gotta spool the fucker up to get any love from it. Displacement gives you more low-end torque which is more your friend on the street and off road where you're more likely to be using lower RPMs. Turbo is better suited for the track IMHO.

Gimme a V8 over a turbo charger any day. Better yet, give me a turbocharged V8!

Actually, gimme a supercharged V8 please. You can keep the turbocharger for yourself.

The reason why the Twin Turbo 300ZX was faster than the 350z was because... it was twin turbo'ed. The 370z on the other hand is great engineering.

In fact most of the Nissan Engines I'd consider to be from great engineering. They never really needed turbos to make fast sporty hi-tech engines.

I never knew why the Nismo editions or like the SE-Rs were not turbo'ed. This is good news though, I'd like to see a turbo G37, even though it already is nearly as fast/faster than the 335i with its Turbos.

I love the VK45DE V8 engine in the Q45 and M45s. A supercharged one could compete with the BMW M* series and AMG series vehicles nicely.

I do agree with that completely! It all depends on what you want, though. Turbo lag sucks, but it's a fact of a turbo unless it's a horribly undersized turbo, in which case you'll have quick low end torque, but it falls flat on its face after about 3500 rpms. The best setup (in my opinion) is to have 2 turbos of different sizes. A small one for off the line and a big one for when the little one runs out of breath.

with all the new technology out for turbos you can get little to no lag plus high top end power...

not to surre if nissan would turbo the Z beacuse then it would start stealling market from there GTR.

Maybe, but don't you think the GT-R is too much of a boutique item to really be threatened by a turboed Z?

Also, I know this is a long shot, but if I recall correctly the Japanese are big on hair-metal bands. That being said, does anybody here think the GT-Rs name might have been inspired by the one-hit-wonder 80s power band GTR?

Just a thought...

Nah, the Skyline GTR was first introduced in 1969 with the 2.0 litre S20 i-6 engine.

thats all ford did with there F250 & F350 super duty diesels... they have a low end turbo and a high end turbo to help when you have a big load...

variable geometry turbos, twin scroll turbo. new technologys that help eleviate the lag issue. small automotive is just now starting to get some of the better technology that has been in big diesels and over the road diesels for the past couple years. turbo technology is starting to pick up now days its been moving slow for far tooo long.

a turbocharged z wouldn't compete with the gtr. z is basically entry level and the gtr is for the high dollar guys who can afford all the tech that's in the gtr. the cobalt ss doesn't compete for sales with the vette (not the best example).

if car companies start turboing their engines on a regular basis it will probably be on very small displacement engines so that they get gas savings with enough hp to actually sell the car.

Ahh forgot to write back here.

Nissan is bringing back the 240sx (Yay?!)

Its gonna have a naturally aspirated 4 cylinder, alongside a turbocharged one aiming for around 250-ish horses and of course, RWD to make it funner than the MazdaSpeed 3 and whatnot.

I think its great because nothing would ever make me want to purchase a Sentra, but a 240SX could be another story.

any one knows how to install the air damn fog light on an 08 X
