Good day everyone, one morning I was on market place and found a VG33ER forsale for a decent price and for a and was a good few hours drive but I picked it up with no prior intention of swapping my pathfinder. The swap is pretty straightforward along as you have all the parts from an ER to swap. It is also 02 Xterra ECU swapped on the original body and engine harness. The pulley is swapped now as of writing to the 4x4parts 2.4 quick change pulley on the stock SCB cut off. It makes a significantly more amount of power than before and is absolutely worth it if you can afford the premium gas. ALTHOUGH, it seems the MPG has been improved since the swap at least at partial throttle which is pretty cool. It's also running factoy R50 airbox with all original sensors. Here's what was swapped Lower intake Injectors Fuel rails (minor differences) Supercharger Spark plugs Spark plug wires Thermostat 180 to 170 AC tensioner only NOT alternator Belts Crank pulley Water and ps pulley NOT alt ECU and plug Pas side valve cover (only for PCV valve) To swap the ECU most of the pins are in the same locations how ever not all. you WILL have to solder a larger pin on the orange IACV wire and to make the SCB safety work you can reuse and replumb the map/baro switch as the SCB and it works the same. All valves, sensors and anything else are original 97 pathfinder. You will have to run different length belts for all 3 now that the V belt is deleted, the crank and water pump are different size and the super charger belt needs to be a 5 rib and shorter unless you swap the AC comp. Cruise even works too! It drives incredible and I could not be more happy with the result. before the pulley it feels like a more peppy VQ but after the pulley it pulls harder than one for sure. When I dump the clutch I'm always first off the line even to the diesel guys that book it off the light (i'm looking at you Dodge owners) and it seems to run cooler than my friends bone stock X since mine has a hole in the hood and gets good cooling. Thanks. Donor engine in back of my r50 On floor after getting it home repinning the ECU plugs Cleaning Radiator shows up Installing charger and intake *borart voice* VERY NICEEE

Thank you! haha. It's been a treat for sure. I was going to do a write up style post but didn't feel I had enough pictures to go with the information.

I love the sneaky bonnet hole! Cool conversion mate and thanks for sharing

Even if the dizzy is new it is common it goes out. My last one went because the little condenser on the side blew and wouldn't let enough voltage to the coil. I think no continuity or high resistance means it's bad or something like that. id have to check the old one. The fuel pump moves pretty slow so as for now assume its good if its flowing. If it doesn't change with the Maf unplug temp sensor and if that still won't work unplug the throttle. the NA VG33 ONLY requires MAF, Cam signal, Coolant temp, O2, and a throttle sensor to run properly. to a varying degree one of those can be non functional and it will still start no problem. every other sensor is OBD and emissions and doesn't affect tuning and engine performance. Unplug your primary O2 (post cats don't matter) and see how that runs. My bet is still the dizzy or its timing. it should idle even with both idles unplugged just not very well. EDIT: You won't even get a code for the dizzy if it's bad. I wasn't even getting misfire codes and the think could barely idle with out sounding like a Honda. sorry honda guys

Not sure if my answer went through but I’ll try again lol exactly. If pin 1 was ignition signal then it moved to pin 1 in the X ecu. But pin 8 on the r50 is fuel pump so that moved to 11 on the X. I was able to sit with both pin out sheets and write each pin and what it converted to so it was easier to swap when it went in. This way it was a turn key upgrade which it would’ve been if I paid attention and didn’t mess up the fuel pump pin lol. 8 goes to 11 not back to 8 haha. 1 for like 100 isn’t bad but there wasn’t much to it really. Everything works no downsides once I started going it became fun but would I do it again? Absolutely the F not! That repinning sucks
