Okay heres a question,and a general observation. I read a few peoples specs of thier cars on here. WE got fully built bottom ends, some built heads,, tt induction, but yet only 13 psi and like 427 whp? (thats a broad generalization and and estimate) i mean, coming from my past honda experience, with a bolt on off the shelf DRAG/turbonetics kit for my Hybrid gsr turbo hatch, with hondata,, fully stock motor,, 320 whp,, low torque but hey its a honda,, that was almost 4 years ago!! I mean do the vq motors not many good power with forced induction and good tuning?? something in my mind tells me that these motors were def not meant for boost, and there should be something alot easier like a rb 26 that can work in there... let me hear your thoughts.

 

I know a guy with a vortech SC with 430 whp/340 lb ft at 7psi. Granted he does have cams, headers, exhaust.

Another guy has an APS TT 463whp 445Wtrq 9.5psi with cams, exhaust.


Im 99% sure both are on stock blocks.

 

oh okay im just putting it out there, i mean its a short observation i had, just wondering. rb26 seems like the way to go though,, research is already there, as well as the market,, and i think when the skyline comes here,, the interest in the z wil fade down.

 

The gtr(no longer associated with the skyline name) will not use the rb26 but it may be a tt v6 or na v8.

 

My thoughts as well.



I've barely looked at F/I applications for it's not something I plan on doing within the next 6 months...perhaps when the Z is no longer my daily driver. That being said, the little product research I've done on F/I for the Z the cost always seems to be double another vehicles cost for the same F/I application. Again, I'm basing that off limited research and shopping so take it with a grain of salt.

 

To modify a 350Z with an RB26 motor would cost more than building a bullitproof motor and boosting the hell out of it. There would be a need for a full standalone, and you would loose all of your creature features of the Z like traction control,ABS and VDC, as the stock ECU controls all of those.The stock ecu also works off a CAN bus system where information from every sensor is relayed to each unit in the car such as the ECU and BCM, heck the ECU even controls the Air Conditioning when in WOT.
Doing an RB26 swap would in the least would be stupid..A properly built VQ motor will handle plenty of power reliably.
As for the Skyline affecting the 350Z market, I think it will actually do the opposite and help 350Z sales. The GTR will sticker price at an "EXOTIC" level and most people will not be able to afford one, and therefore consider the purchase of a 350Z instead.

 

1. you get more drivetrain loss on a rwd vs a fwd car for one thing...

2. if you are going to custom fab a rb26 into a Z you might as well fab a 2jzgte into it. Just because the RB26 is a Nissan engine it can't bolt right up to the VQ's tranny and you are good to go.

3. Getting parts for a RB26 in America? forget about it.

4. The skyline is here... its called the g35... NOT ALL SKYLINES ARE GTR's... there are plenty of no frils r32's with 4 doors and 180hp NA.

5. The GTR won't fade the Z since they aren't going to even be close in price.

EDIT:

I just looked it up and the base Skyline R32 sedan is inline 4 and has 92 hp NA

 

The GTR wont be released in the US until Spring 2008, which is close to the end of the Z's production cycle. Decline in interest after 6 years is pretty obvious with any car.

 

End or production cycle? I dont think so. Its a pretty popular selling car. Next year it really calls for a full makeover. Nissan usually introduces some new parts like a slightly different taillight or different markers right before a full makeover. I expect it to look more like the M45 but shaped like the Z.

 

Umm... i dont know what threads you've been reading man but basically every guy with a built motor is running well over 500whp/500tq...

A lot of guys WITHOUT built engines are running in the 420/420 est. range and a whole lot of guys with jsut the bolt on F/I are running at 350.

Consider that our compression is already super high and were squeezing out at least another 100 horses...thats really good.

Honda cars are lower compression (correct me if im wrong) so are more friendly to higher levels of boost. **** man we make 100hp off 6psi, i think that's really good.

 

Just to clarify, I meant the production of the current generation. Cars are most popular their first year then interest curtails, no? Also wouldnt it be make more logical to take cues of the next gen G35 rather than a full fledged sedan?

 

its not all about the boost pressure, some FI applications flow more air at lower levels than others. Like jwt vs greddy same power, different boost.

 

1. This thread is dumb.

2. The skyline is already in the us, but it's called a g35.
