VG30 to VG33 SWAP, Step by Step Starting Today 8/26/17

Very nice step by step with the pictures !

 

I guess you have a body lift as the upper radiator brackets are upside down, did the same on my former 87 Hardbody with the body lift.

 

A member on Infamous forum is swapping a VG33 into his Hardbody and discovered most of the JDM VG33's that are for sale have the alternator on the pass. side, he wanted to keep his on the drivers side, where it is on the VG30, but he found the oil filter bracket was too thick and it would not allow the alternator to clear , so he replaced the oil filter mount with one from a frontier, it is thinner and allows the alternator to bolt up and clear.

 

A tip when removing the hood and getting it to re align is to drill a hole through the mount into the hood on each mount, than when reinstalling use a drill bit to line up the hole in the mount into the hole in the hood, once the drill bit is through both holes you know it is in the same location it was before being removed.

Just ran into that exact problem with the oil filter housing. I originally had done a mod on the bracket, which helped extend the alternator to clear the filter, but it put the alternator into contact with the steering unit. Yesterday I pulled an oil filter mount off of a JY Xterra that is thinner and changes the filter angle. This also makes it MUCH easier to install the higher amp alternator.

The Xterra/Frontiers have the accessories in the same place as the wd21 so it would make sense that those brackets would work.

 

Would be a good time to install the supercharger off an X while you're at it :D

when I did mine I used parts from a 2000 exterra the angled oil filter mount a/c bracket and ps bracket, crank pulley.

I think I posted all I did to mine including a 95 dash and main wiring from taillights to headlights plus the smaller harnesses

Haha. I have a complete VG33ER sitting in my garage. It would make a great replacement for the 500k 3.0 in my pathfinder. But it needs a rebuild first.

I'm confused on why you're removing so much excess stuff. Why are you taking the entire front clip off? So you don't have to drop the diff?

 

While some of the stuff I've pulled off may not be "required", it makes access to the engine and the differential A LOT easier. I did remove the differential as well, and honestly removed ALOT of stuff that may not have been necessary for the engine swap, but it was stuff that I was going to overhaul anyway.

 

Even though there may be excess, it's meant to be informational. Unfortunately I was editing Item #23 above and the forum kicked my edits and trashed a whole page worth of text, which I'm trying to get admins to assist with getting me editing rights to this thread...

I understand and appreciate the informational aspect of it, was just confused :) once you're done I might add some additional information for those that are thinking of going the full vg33 set up instead of vg30 accessories as I believe you are going if I'm not mistaken. Finding information the way I went is a challenge

Gotcha. Yeah, I feel for you. There are alot of sites that "talk" about the swap, and list what was changed, etc, but nothing that really talks about the pitfalls, the minor differences that become MAJOR changes, etc. those are all things i'm trying to cover with this thread. I have literally taken over 3,000 photos during this swap/conversion, and i'm going through them pic by pic to make sure i don't leave anything out, then editing with the arrows/notations so that people don't run into the same issues I did. It might be overkill, but it will literally be step-by-step.

 

I almost went with the full VG33 conversion in regards to the accessories, but it would have required fully swapping everything to the opposite sides, and that wasn't gonna work...lol.

I've always used 5w30 in mine. 10w30 is not really recommended for anything anymore. 5w30 gives the same high temp protection and better cold flow rate. Sometimes I have ran 0w40 in the truck but only when I had some left over from my VW. It started up in -30C like it was summer time!
