i know..... but bottom line though we dont know whats coming.

A 4 cylinder turbo with equivalent hp as the 370z but with 400 pounds less would be a much more enjoyable driving experience. The VQ should retire it had a great 11 to 12 year run but it's time for a refresher. The vq37 has more issues with oil burning etc then my vq35de ever had so progressively it's getting worse reliable wise. My old 350z had the same amount of oil to the drop for 7 years of me changing the oil yet this motor eats up oil.

I'm not hating the VQ as this is my 3rd Z in 12 Years but it's time for a refresh. The Z also needs to go on a serious diet and lose at least 300 pounds

i just dont see 300+BHP out of a 4cyl turbo coming in a Z. i would love it since it would probably be a pretty strong block where you could do a turbo swap and bump the HP a bunch without having to do a full bottom end forging. so it could work in the long run i guess.

If I had to bet I would say it will definitely be a 315 hp or slightly more 4 cylinder turbo with a weight of 2850 pounds with direct injection which should be able to get around 31 mpg highway 24 city. This combo also should yield a 0-60 time of around 4.2 seconds making it faster and more economical then the current Z.

Kia has a car that may come out with a 315 hp rear drive 4 cylinder turbo... I can't see nissan letting Kia win that battle.
Also tuners now are able to boost a car on higher compression successfully so the car could have a 10:5:1 ratio and be boosted at 18psi with a good size turbo but not too large to cause a big lag and achieve those numbers.

This is a lot better then shoving electric motors on an NA car like what was talked about a year or so ago.

what kinda torque are we talking about with these turbo 4 bangers?

More torque then ours 370z now... I would guesstimate 315 hp or 325 hp with 305 ft lbs of torque.

all good points. i mean it could be interesting to see what people can do with a just modding the already boosted engine. i mean i've seen some interesting number pumped out of the boosted 4 banger in the genesis coupes so i'm guessing it could be nice. plus i agree the weight saving would be lovely. for the size of the Z being around 3200lbs is a bit much. i mean the GTR is bigger and AWD but its only 3800lbs lol where is the Z hiding all that weight :bowrofl:

and no Kia will not win lol :tiphat:

The best thing will be if we start with a weight of 2800 pounds then doing race seats, forged wheels or lighter wheels, 2 piece rotors, yank out the spare, braille battery And maybe some lighter suspension and you now have a car that's 200 more pounds lighter... my 350z I had I shaved 300 pounds off and the interior was fully in tact.

stop it lol you're gonna make me want to strip mine out. but to be honest i rather the car just come lighter stock. i like being able to say when i beat higher power cars that my only weight shaving is from changing the exhaust and intakes lol

Whatever some of you guys are smoking, puff puff pass I want some ;)

If you put a 4 cylinder in a Z then it will be called a Silvia/240SX instead, which I really wish they would do, and more in the range of what is being talked about. 2800lbs or less, 4 cylinder turbo direct injection 280bhp, 270ft.lbs. 8000 redline FTW

The history of the Z has always had some sort of 6 cylinder in it, and Nissan tends to be a bit purest. It would be nice to see them put a little forced induction back in to the Z, and bring back the twin turbo, but I personally highly doubt we'll see a 4 cylinder Z in the future, but more along the lines of a new model or the rebirth of an old one.

From looking at the data of new turbo 4 cylinder motors that are being produced it would probably look something like this realistically for a 4 cylinder Z based on what is out there now, and some future motors. Most likely you would be looking at maybe 50 to 75lbs of weight reduction if you're lucky, if it's still in the Z34 chassis. A displacement size 2.0L to 2.6L, direct injection, turbo charged. No more the 300whp but mostly likely in the 270whp range. Torgue is a real guess anything from 200 ft.lbs to 300ft.lbs. depending how high strung they make it. I think we would be really lucky to the higher side of those numbers.

Right now I think the only 4 cylinder turbo gas engine Nissan has is the 1.6L MR16DDT which makes 188bhp and 177ft.lbs. and comes in the Juke, and the same motor is used as a base in the Deltawing. The only other gas turbo motor in Nissan's line up is the GT-R's VR38DETT. That might give you an idea where Nissan's head might be at.

I've seen a few 350Z's with the SR20DET which isn't the best motor but it would be fun as hell. Here's a video of one.

I was told there is almost zero weight saving between the VQ35HR and the SR20DET both weigh in at around 330lbs.

Well I was wrong it's going to be called the IDx/510 not the Silvia/240SX
Here is your 4 cylinder!

old news bro lol

Funny, Nissan just confirmed that it is going from concept to production I believe it was yesterday, not sure how that is old news.

well you didnt mention the confirmation of production. the article said it but didnt open it. the car itself was shown a while ago. thats what i was saying. dont go and get your panties in a twist.

The weight savings won't be directly related to the engine but that should give at least a 50 pound reduction. The reduce in weight will come from a downsize car... The scion frs weighs around 2700 pounds due to the size.
Also nissan. Has this Kia stinger that will be a competitor with a 315 hp 4 cylinder turbo. ..

Nissan are looking to bring a lighter more fuel efficient car this has been spoken about by the high ups at nissan. There will be a 4 cylinder turbo and probably a v6 version offered either under the nismo brand or as a side option.

Please someone remember my prediction when nissan make a 2850 pound Z... no number just called Z. The car will have around 315 to 325 hp with a 4cyl turbo.
