Are all vq35de engines the same??
Just trying to find out if all vq35de non hr or revup are the same.
currently have a vq35de 2003 infinity sedan 6 speed.
Miles are about at 270k the engine is starting to act funny and I found a motor out of a automatic g35 90k miles that's a regular DE Im wondering if this swap is plug and play or did they add extra sensors or anything for the 1st gen DE.
I know the 6MT 2005-2006 is rev-up then you have HR.
I know that the 2003-2004 had the narrowband sensors on the exhaust/headers.
any info would be great as I'm gonna pull this engine and rebuild while having a newer engine inside.

My car is a 2003 but the tunable version.
Currently debating if I want to buy this nismo-differential 2016 3.7 with lsd.
I got a cd009 I'm looking at for $780 at a pull a part.
found a engine with 60k miles $3000Found nismo-differential $700
Reason I'm replacing all this is car has 275k miles body and interior look amazing. Got the car for 2k for less then 7k can have a rare g35 sedan 6mt with 66k miles on parts.

2003-2007 with 5AT are all the same, no changes.
2003-2004 with 6MT were the same as the 5AT.
2005-2007 with 6MT was the rev-up which used the same short block (ever-so-slightly better rods, different oil pan baffle). Heads/intake were completely different due to the exhaust cam actuator stuff.
As previously mentioned, the 5AT uses a different pilot bushing (it's more of an insert than anything) and the 6MT all uses an actual pilot bushing.
That newer style 3.7 diff will need a little work done to it since the yoke doesn't directly bolt to your driveshaft, pretty straightforward swap, google it. However, 3.7 makes for a VERY short 1st gear so... your choice.

Ohh the stock VLSD is FAR superior to an open diff, it's just not great for autocross because it gets hot quick after a couple laps.
Honestly I think you should focus more on tires and getting a better 60' time. Stock street tires are only going to get you like a 2.5 60', with a better set of tires and smaller wheels you can EASILY shave the same .2 off, closer to a full half a second with street slicks.
At NA power levels you can even run slicks without breaking anything (just keep an eye on your motor mounts, they will be the first to go) but honestly it's kind of pointless at that power level unless you just REALLY want a better time.
