What say you? Direct injection will boost hp 5%, give better fuel econ and better low end tq.

 

Not happening. The 2009 G37 Sedan has been confirmed and its using the exact same G37 Coupe VQ37VHR motor. I highly doubt the Z will receive direct injection.

 

^ sadly but very likely true. Although the new and improved Nissan company has taken bold new steps in their design to increase revenue, they also seem to know when to play it safe and cash in on their past work - in this case, reusing the VQ37 in the next Z without further changes to the engine itself. I personally would like to see a better engine in the new Z than reusing the vq37, but thinking Nissan would add more money and use a different engine in the next Z is probably wishful thinking.

 

^^ yea, and I rather pay a cheaper MSRP and have 5% less hp.

 

I wonder what they are going to do to the engine to make it different. I don't believe that Nissan will put the same 330hp version in the Z as they have in the G. Any Ideas what they will tweak to get a few more hp out of the Z engine?

 

If they put DI in it will be a negative for tuners.

The DI injectors are much harder to find replacements for, so FI will be MUCH harder to put together.

 

Sorry to break it to you, but Nissan doesnt design motors around "leniancy" for tuners.... alas, 07-08 350Z , GT-R. Its already hard enough trying to keep the CEL from popping up with simple HFC's and TP's. Nissan designs a motor for the Z that is powerful enough in NA form to please the masses and thats that.

 

...Did I imply that I didn't realize that, and DI is really useful in forced induction, but not yet so much in NA applications (cost benefit ratio isn't there yet).

I was just making a point, of course Nissan isn't concerned about that, but it would be a bad thing for us...

 

they are going to change the HP number on paper to make it different, is that the right answer?

Nissan co. is a marketing *****; even though their engineers are good, their marketing department sometimes seems better. They've changed numbers only on paper to differentiate the current Z and 1st gen Gc, I bet they are going to pull the same trick. G, 330hp, Z 337hp or somewhere in that line.

 

Good point, for NA it isn't AS useful... perhaps they can just upgrade the tranny/shifter compared to the G37.. I hear it's still not the greatest.

 

I can somehow believe that , lets say it...

We now present to you, Carlos Ghosn...

*Croud cheers and claps, and the standing ovation* !!!!!

Carlos Ghosn:

"With inspiration from the 40th Anniversary of the Z, we give you...

Ladies and Gentlemen.... the 2009 370Z"

Croud :

"Oooooh...Ahhhhh....Yeaaaaaaaaaaaaaaaaaah!!!!"

Carlos Ghosn:

"With an all new, VVEL 3.7L , with an available Three Hundred and Thirty-Seven Horsepower!!!"

"Choose from an updated 6-Speed Manual Transmission or an All New Slushbox 7-Speed RevMatching Automatic, engaged with heavy-duty magnesium paddle shifters!"

 

So, how was the 2005 the 35th anniversary, and 2009 the 40th...wouldn't it be 2010?

 

GA16, SA18, SR20!!.... they did in the olden days.

I think the HR was forced on to keep up the pressure on the outgoing Evo's and Sti's moreso than to put the icing on the cake of the vq35. Now with both bringing out new models with crazy torque, I think the 370z will once again be behind the 8-ball.

A fair few people (just read some new owners threads) bought the Z over the Evo's and Sti's due to styling (sacrificing the performance). Nissan really need to make sure the 370z looks just as sexy or sexier than the 350!

 

Don't forget the "electro-magnetic push-start button"

 

the 07 Z already has direct injection

 

It has direct ignition, meaning coil packs and no distributor. It however does not have direct injection....see the injector location in the lower plenum. Its not even connected directly to the head, its literally spraying into the port from the plenum (aka multi-port injection).


I still say it would be a dumb move on Nissan's part to invest in a technology like direct injection, especially given other more cost effective options like putting an exhaust system on that flows worth a damn.

Not to mention the more cars the motor goes in the easier it is on Nissan for warranty maintenance stuff.

 

Nissan already has variants of the VQ with direct injection, and from most sources Nissan intends to go full fledged with direct injection across its line up globally starting around 2010.

TK

 

None are currently US bound. I don't think (if the new Z is for 09, and possible 2010) it will come with DI initially. Its possible, but the cars that have it are the economy cars. Its advantages are more with fuel economy than tuning for power.

 

oh, I did misread their website.

 

That still a pretty good jump 337hp in a lighter car then the G37 that thing should fly DI or not, 337hp would make the present thought to be heavy 350Z break 5.0 so the 370z should be in the 4.9 r 4.8s 0-60 times or better. Not bad.

I had read something about 320-325hp so 337hp is great news.
