Spoke to Nissan rep at Philly car show
 

Was at the Philly car show today and spoke to the Nissan rep there for a few mins, who was a really nice guy and seemed reasonably informed. I asked what the future held for the Z and he said that they've been told that the 2012 will be getting direct injection that will bump hp to approx 360. He also said the car will have a revised front and rear facia. I asked if he knew of a release date and he said they didn't have a definite date yet, but his best guess would be mid-summer.

I realize anything short of an official announcement is hearsay, but I thought you guys would find this interesting nonetheless.

direct injection? damn it...

I would hope that if that information is true, GTM or likewise will come out with a direct injection conversion. I am looking forward to seeing what the new fascia looks like though!

If this Is true Don't big a 2011.

how much would a conversion like this cost? speculate?

That'd be pretty neat if they did that...

ehhh...cant justify a trade in if this is true. ill wait to see the dynos and how well they take to mods>>> right now all i can be happy about is if the crack VVEL

A DI mode would be cool, but at what price?

Can anyone explain direct injection (Newb)?

It's about time - mebbe an upgrade? :D

Hopefully the price premium won't be drastic - most of the other car manufacturers have introduced DI engines with little change in MSRP.

Fuel is injected directly into the cylinders vice the intake manifold. Allows for more accurate metering of fuel and control of AFR's. Downside is typically an increase in price due to higher temperatures and pressures the injectors must withstand.

Another issue, I've read, is carbon buildup on the valves, as there's no wash of fuel over them to clean them up.

indirect injection fuel and air are pre mixed in the intake manifold, in Direct injection they are not, air still comes in via intake mani but fuel is sprayed directly into the cylinder...resulting in more power,

Hmmm, choices choices!

Nissan rep or car show presenter?

Grr. Maybe I will wait to 2012. I wasn't really expecting power boost.

no offense but if there is no official leak i wouldn't bet money on it... a nissan rep knows nothing about whats in the pipeline consider them a glorified salesmen.

I highly doubt this.
Maybe 2014. lol...
I'm sure they'll do some mods to the body but not the engine itself.

Seems a little soon for them to do this. Maybe in a couple more years. I'm not buying until december so if it's true, I'll count myself lucky.

360HP for the base Z or the Nismo? Where is the increase in HP is going to come from?

I really don't see this happening for 2012. Maybe on the next model Z35. They havn't even really addressed the oil cooling issues yet.

Ya, I had a Nissan "rep" tell me at last years Car show that in 2011 there was going to be a hard top convertible... okie dokie

Argh!!! I was dreading this for a while now... Who knows if its true, but if it is, I'm going to wish mine had it. Anyway, I believe the Infiniti M56 already has DI injection, so Nissan has the technology in place already. Rumors have been floating around for a while now, that the G was getting it next. So these rumors aren't too far off.

QFT! thats why i see some validity in this...a DI Z would be awesome

The discrepancy here, is it a 28 HP gain or 10HP. From a less than certain source. To put off the purchase of a car based on this seems a little silly. The extra money Nissan will charge may very well be off set by an exhaust and CAI's today. Maybe not.

well i got my Z so am ok, but its not just the "out of the box" numbers that matter here. DI is more tuneable by far, mod for mod it will squueze out a little more HP than non DI...once you do they math on a full bolt on and tuned Z, its a very significant.

Cadillac has a DI and NON DI CTS, with that bieng the only diff, offered same year...one makes 304hp 274tq, the non DI make like 264hp and 250ish tq....

Wow!

I wouldn't be surprised if this was true, honestly the 370z is being eclipsed handily by the Mustang GT and is going to face competition from the coming refresh of the Genesis and now the uprated v6 Camaro, it would need this power increase to stay competitive IMO. In its current state, I don't see the 370z being really competitive for much longer.

whats the uprated V6 camaro getting?

As much as some don't want to admit it, this is coming sooner rather than later and has been in the works for some time. Just check this article:

Infiniti Readies Direct Injection for M37 and G37, Unsure About New Q - Car News - Car and Driver

cool. but im fine with wat my Z provides today. even at the advertized 332hp that extra 2hp at the end just makes all the difference. i know when that last 2hp just kicks in.

I believe it's getting a bump to 325 or 330hp. Don't quote me though. I read so much everythng seems to blend together.

wow 5hp at the crank is dangeriously furious power. are they ready for it?!!!

Is Honest Abe always honest?

Who knows how valid that information truly is. It would be nice to see the Z evolve a bit more (even as a current 370 owner). But I certainly wouldn't hold off buying a Z now if I were in the market for a new one. This kind of future guessing gets people waiting forever...always worrying they won't get the best. News flash: there will always be something better available down the road. It happens all the time with people waiting to buy new Mac computers because everyone thinks the model they want is next in the update cycle. Just buy it if you're shopping for one.

30HP more or less is about right I think. When the Cayman S got DI it saw similar gains. It doesn't sound like much at first but that's right around the same gains from a VQ35DE to VQ37HR.

I'm not trying to stir the pot here, I'll still love my car, but it will personally bother me a bit.

The way I would see it is how the G & Z got updated, the Infiniti line got the VQ3.7L first for about one year and then over to the Z. I could see an updated G37 in 2012 or 2013 and then 2014 the Z gets the update.
Who knows where Nissan is at testing, a lot of good & bad has come from DI so far and hopefully Nissan is taking ques from others (and with the new Juke).

Once I get a S/C, the gains from DI will be laughable. Booooaaahahahahahahah!

I know....;)

It would make sense to update the Infiniti M37, as the M56 is already DI. However, since it's a drop in for the G, it almost certainly is the same for the Z. If the engine is ready, I see this happening sooner than we think.

HP gains are inevitable, as you can tune much closer to stoich, and extract more power from the engine.

Makes me wonder why/when the GT-R is going DI...

woah, i think you woke up the french guy. :tup:
