350Z vrs G35 engine

Post by **pfowler991** » Sun Mar 02, 2003 7:30 am

Does anyone know if the engines are the same on 350Z and G35? Would parts be interchangable? Last but not least...what is an ECU?

Thanks in advance,[email protected]

the only difference i know between the too engines is on the 350z the big plastic cover has a nissan logo and on the g35 it has the infiniti logo. the rest is the same

minus 5 or 8 hp on the g35 for marketing reasons.

The intake. That's the only difference. Seriously.

My friend has a G35C and he knows a lot of 350Z people. He's also friend with a few guys at Technosquare who say the G intake is much more restrictive than the Z one and swapping the intake arm should yield some results. The ECUs should be basically identical, since the Technsoquare reflash carries over with no problem.

speaking of intake, anyone seen the inside of a 350z intake? its nice. very smooth and everything.

I was told from an extremely repuatable source (that actually put a bunch of intakes on a flowbench for tentative measurements) that the G35C airbox flows better than the 350Z box, but in the 350Z, the tube from the box to plenum is better flowing.

So basically a G35 airbox and 350Z intake elbow would be the most ideal combination.

or replace it all with a pop charger

Cold air intakes on 350Z/G35Cs confuse the intake temperature probe. There's a long discussion on it at my350.com. Sticking a filter on the elbow just results in a good amount of engine bay air going into the engine. The stock airboxes are just fine. Maybe a velocity stack.

yeah, pop charger is not a cold air intake. it had the best dyno results of all that i have seen.

Because it's dynoed with the hood open.

generally speaking the pop charger doesnt fare well against a properly designed cai, but on the 350z it had the highest output of the comparison. i dont remember who else was in it. never done myself so i cant validate it.
