You'll have to watch what you say next time. In case you didn't
know the rest of us can see what you post, and can debunk your claims if we're so inclined.
by all means defend your engine.. that's what forums are for...
it's all in good spirit.. i'm not here to cause flame wars or fights... it's nice to have an intellectual debate once in awhile...
I agree.. i put down the american engines, but i never put it in comparison to a Nissan engine let alone the VQ that was your initiation
Firebird
Nope. We're comparing the top-of-the-line flagship models of each brand. If the 350Z isn't the brand's flagship, what is? The Frontier pickup truck?
the problem is that the "top of line" nissan in America is not the "top of the line" in Japan... JDM models are far superior then their USDM counter parts
Firebird
Well, this is at least a reasonable assessment. Then again, three more camshafts, continously variable valve timing and lift and eight more valves should make up for some of those 2,167 cubic centimetres.
Some perhaps.. but everyone has heard the term "no replacement for displacement" how about u compare an American V6 to the VQ?? there ya go.. same number of cylinders.. still more displacement.. but a little more balanced...
Firebird
Why would I include the weight of the transmission? I thought we were talking about engines, not gearboxes.
the powerplant is nothing without a transmission... can't have one without the other... or perhaps u didn't include purely because of your engine/tranny combo not being lighter anymore (purely speculation, i'm not gonna scour the entire internet evertime i make a claim)
Firebird
Weight distribution (f/r):
Corvette ZO6: 53/47
Corvette Coupe: 51/49
'02 Camaro Z28 Coupe: 56/44
350Z: 53/47
M3 Coupe: 50/50 (actually 50.3/49.7, but it might as well be rounded off)
M3 Cabriolet: 49/51
interesting... is that 350 USDM or JDM tho??
Firebird
I'm not even dignifying this level of ignorance with a counterpoint.
obviously u didn't read the rest of the posts that continued to touch base upon perhaps u should read the WHOLE thread...
Firebird
You'll have to forgive me. I've never heard of "Best Motoring". In any case, I cannot tell you their motivations for exclusion of the ZO6. Perhaps all-out embarrassment of the rest of the field at the hand of the Corvette?
Just kidding of course.
u should look into them.. real life numbers and on paper aer always different.. Best motoring puts the car to the test... the reason there was no Z06 (also i mentioned this in a later post u didn't read it) was because z06 was never sold in Japan.. only C5... so the C5 became the american bench march
Firebird
It's actually a little longer than the VQ, but is (relatively) far shorter. The VQ's DOHC heads are huge.
normally i wouldn't point this out, but u sit and attack my english as a point of defense rather then using some common sense and proof reading a little...
so if i read u literraly u're sayign is a little longer but relatively shorter...
but what u meant was "little longer but not as tall"? correct?
Firebird
Ironic, since the Camaro and Corvette both employ "front-midships" engine placement, just as the 350Z does. The Corvette's pop-up headlights and associated motors certainly add a lot of length, as does the Camaro's very large air intake. The engine in both sit behind the front axle.
my S-13 has pop up headlights it doesn't add very much to it's length... infact it doesn't look very diff in size with the the Silvias non pop up... but if u say so.. i'll get to the intake point in a minute...

Height (in metres):
R34 GT-R: 1.360
350Z: 1.310
Corvette: 1.212
Width (in metres):
Corvette: 1.869
350Z: 1.816
R34 GT-R: 1.785
Length (in metres):
R34 GT-R: 4.600
Corvette: 4.566
350Z: 4.310
ya the car is longer and wider but slightly shorter... (R34 is a fairly big car, R32 which u got your engine specs from is smaller)

You can't assume everything is equal because nothing is equal. And it isn;t measuring effieciency whatsoever. True engine effieciency would involve the comparison of the amount of air physically inhaled into the engine's combustion chambers to the theoretical maximum (displacement). This is actually called volumetric efficiency. Both the VQ35DE and LS6 have near-100% volumetric efficiencies.
I understand volumetric effeciency... but that doesn't compare the 2 engines to each other directly... all it says is that if A sux in 400/400 CFMS and B sux in 600/600 they're both 100%... since u like digging up so much numbers, and i know the internet in Calgary is blazing fast.. see if u can find the Theoretical maximumum vs the actual air for both engines... if they're actuals are near each other i give up.... but i think u'll find the Chevy will be in the 600's probably and the VQ will be in the 400's maybe... so in they're own class ya they're effecient.. but can't really compare to each other that way.. u know what i mean??
I didn't event HP/ltr man, i've seen it used Everywhere in almost every major publication so it's not like i'm trying to set a new standard here.. hp/ltr is widely accepted..
Take for example the honda's S2k engine the reason the engine is so Appraised is not because of it's 220 hp.. but becuase it does it in only 2 liters!!! and 4 little cylinders... is it faster than a LS6 NO? but is it more impressive? i deffinately think so...
Firebird
But the LS6 doesn't make 227hp, it makes 405. That is my point.
did u even understand the point i was making??
Firebird
Which I interpreted literally, as the boxing term goes. I guess I should assume the rest of your broken English isn't written in prose?
for your information tho this really shouldn't matter... I've lived in Ft Mcmurray, New brunswick, London, Toronto Ontario... so i'd say my command of english isn't so bad... deffinately better then your average joe i've met... (but that has nothing to do with our topic)
Fair enough. I'll refer back to this:
But hey, it does make more power "CC for CC"...
Firebird
Well gee, I'll concede this point. A far larger V10 with DOHC, double-VANOS and 24 more valves than the LS6 makes 100 more hp. And revs to higher rpm.
But I can think of a certain American V10 that is dimensionally smaller than the E60's V10 and has as much power.
I brought the V10 in because of it's displacement be only .7 less rather then 2.2ltrs... if u drag in the Viper engine into this then it's a 3 ltr difference! that's even worse of a gap
Firebird
10.3 is high for a naturally aspirated gasoline-powered engine. Whether you believe that or not is your problem.
some sites say it's 10.2, but not to quibble about that... u're average integra has CR in the 10's.. and the Type R is 11.1:1 and the F20C from the S2k is 11.7:1
off the top of my head M3 is 11.5:1 i believe...
these are all production cars... so i guess it's a matter of opinion.. u think it's high i think it's low.. some ppl think 300 hp is ample some ppl think it's not enough...
Firebird
Sure I'll explain: those two turbochargers pump out a measly 5.6 PSI of boost.
Source:
http://www.turbomagazine.com/features/0307tur_350z/
from this point i can tell u're ignorance of Forced induction
first of all if u didn't know this.. a t25 at 15 psi will put less CFM's then a T3/t4 at say 6-7 psi..
do u have any idea how big an 18G is?? it's bigger then the Evo's turbo.. and there's 2 OF THEM!!
334 RWHP! 110hp gain out of 6 "measly" psi as u put it.... i'm sure with a little dyno tuning and tweaking they can squeeze more outta that (note it's USDM and therefore slower base model) and those turbos are easily capable of 30 psi...

Which large engines in particular? Surely not the LS1, to which Lingenfelter Performance Engineering has bored and stroked the engine to 7.0L and added two Garrett turbochargers to make 725hp. RELIABLY. In fact, unlike Greddy, Lingenfelter has a warrantee for the entire engine.
if u completely ignore economies of scale i suppose yes u can turbo a LS1.. but what are the chances of u seeing a Z28 roll by and hear a PSHhhtt? vs. 350z with a kit u can install at home...
be a little more reasonable man... i'm not talkin about staged forced induction superchargin and turbocharing at the same time or crazy stuff..

Crappy American fuel? Where in the hell did you get the idea that American fuel is of poorer quality than other fuels? Surely you aren't confusing 98 octane RON gasoline as found overseas as being better (or even to for that matter...) than 94 octane R+M/2 gasoline?
on the other forums i've seen.. the Californians are always griping about their fuel... mayeb they're exagerating.. but Cali has a huge performance/tuning scene... so i'm sure they have some grounds to their claim...
Firebird
The Greddy kit makes 5.6 PSI and only 335hp. Obviously the compression is as high as I made it out to be.
335 RWHP! not crank... assuming 15% loss that's like almost 390 hp at the crank...
not for behind the Z06... and this is a USDM Z
Firebird
The VQ in the 350Z is highly tuned. No matter your ignorance. For the record, the Corvette's engines have one (1) single camshaft, as do all pushrod overhead valve engines.
and this is exactly my reason for dislikin the american engine.. they use technology from the stone age... and the main reason they need so much displacement to make power, why don't they invest a little money into RnD and make a 5.7 ltr DOHC MPFI 2 stage VTC and then make ungodly power...
get with the times.... we're in the 21st century...
Firebird
Sure I know what the RB26DETT is. A 2.6L double overhead camshaft inline six-cylinder gasoline-powered sequential multi-point electronic fuel-injected internal combustion engine designed and manufactured by Nissan.
For the record, it has a compression ratio of 8.5:1.
on paper it seems soo simple doesn't it? but without changing internals and only a turbo upgrade.. 600-700 hp is easily attainable...
Firebird
Every single piece of information within this particular quote is made up.
in my long stay in canada i've never seen a GT-R and i doubt u have.. so u hardly have a basis to compare too.. maybe u should do some more research before makin such an accusation??
Firebird
You can turn a screw without doing anything? I must admit, I cannot turn screws without doing something. Perhaps you could use your amazing screw-turning abilities to tighten the loose screw in your head?
the fact that u couldn't place a missed coma and a word, in to the sentence is dissapointing... and u sit and slander my english 👎
lemme rephrase it for u so u understand...
"can turn a screw and make more then a 100 more hp... without doin anything ELSE, can u?"
which means.. if i turn the screw on my Boost controller and raise the boost i can make 100 more hp and it wont cost me more then a 100 bux or so...
i can see u're knowledge stems more into the Naturally aspirated world then the FI world... but i hope u understand what i meant now
