3.5L Engine Differences?

[Ferguson]

New 3.5 SE coupe owner here, and I apologize if this has been answered before but I didn't find it even after searching... BTW, I am in love with this car! (Emotionally only, of course! )

Here, if not everywhere, the A/C is 270 HP, the G35 is 290 HP, and the 350Z is 306HP.

Nissan says same base motor, so what exactly are the differences? Cam changes? ECU chips? Intake/exhaust?

Can the A/C be brought up to 'full' spec?

[bina12834]

intake/exhaust is probably the main difference

[Armed Coupe]

I believe the 350z and G have higher compression, duel intakes and bigger injectors.

[Kango]

Yeah The newer VQs that g35 sedan and 350z uses has 2 intakes or smoething like that~

[marlin29311]

The G and Z use the VQ35HR instead of the VQ35DE - the HR has more reinforced internals allowing for more compression and better load handling.

[LinkNuc]

Yes, but don't forget the G's and Z's used to use the DE and the Z put out 287Hp/274TQ and the anniversary edition was 300HP/260TQ its in the tuning, valves and ECU.

The G's using the DE varied from 260 to 298 HP

[SaiDori]

True, but the OP quoted numbers from the VQ35HR cars.

Comparing the number to the VQ35DE Z's and G's, it's mostly better internals and tuned at the intake and exhaust side.

[LinkNuc]

Yup that's it, plus FWD cars over 250HP present problems for your average Joe Driver with torque steer as rule of thumb.

[Ferguson]

Not sure where torque-steer fits in to this. My 09 (270 HP) exhibits zero torque-steer at all. Sure, with TCS off, the car may slip a bit side-to-side, but still there is no torque-steer. Or maybe I'm just confused by lesser cars....

[LinkNuc]

Oh, wedo have torque steer, don't kid yourself, it's just not that bad, Nissan did a heck of a job managing it.

I was just saying as a rule of thumb anything over 250HP in a FWD starts to present problems with torque steer.

Actually Nissan's ability to manage torque steer is raved about quite a bit in reviews.

[Ferguson]

They did a helluva good job of it too! Just came back from a TCS-off test, followed by driving on suddenly wet pavement, and the car was totally predictable in all situations. If you want to experience torque-steer, try a Chevy Citation from the early 80's... LOL (We used to call them Chevy 'Situations') :-)

I've never heard of that car before

[TheBourneAltimatum]

I've never heard of that car before

thats becuase non of them lasted more than a few months

my dads cousin had one....going up hill near LA, the block litterally shattered (it was the first time GM used aluminum)
