Let's talk 2GR-FE (V6) swap

The goal:

1. Complete, working, 2GR-FE swap (266-280 HP, 5 or 6 speed auto or manual transmission) with no CEL's, missing features, or reliability issues. I am leaning towards automatic (no, I don't care that you don't like automatics. I prefer auto for this particular vehicle).
2. Minimal fabrication. I realize some items are unavoidable, but I want this swap to be as straightforward and repeatable as possible.
3. A complete guide/instruction set once the swap is complete, so that others can repeat.


1. I love the xB, but I hate the lack of power.
2. I think I can accomplish this for as much as (if not less than) a properly built turbo setup after selling my existing drivetrain.
3. I have the time, energy, and money. Why not? I love figuring out new swaps on every possible scale.

The plan:

1. Work out every last needed part and build a master list
2. Determine complete wiring diagram and layout

This thread is not a build thread - just like my previous steering wheel and brake threads, it will serve as sort of a notepad where I jot down and organize my thoughts. Any and all input is appreciated.

Notes so far:

(I'm going to refer to the 2.4L 2AZ-FE as the "2A" and 3.5L 2GR-FE as the "2G" from here on out)

  • AC Compressor: 2A and 2G can use the same unit. Custom lines may be needed based on positioning.
  • Axles: Based on dimensions, V6 Camry XV40 Axles may fit without modification. Need more detailed diagrams to be sure.
  • Accelerator pedal: Research needed, but there's a good chance it will work.
  • Alternator: 2A and 2G use different models; replacement needed
  • ECU and harness: Must be replaced. There is an ECU that uses the same plugs as the xB ECU (pics) but I have not yet found the pinout info.
  • Exhaust: No items researched yet; assuming all items under the hood will be fabricated, but I will search for OEM swaps if possible.
  • Fuel pump: 2G uses a total of 2280cc of injectors vs 1340cc for 2A; probably needs upgraded
  • Motor and transmission mounts: Unknown. I am assuming at least one mount will need to be fabricated, maybe more.
  • Starter: 2A and 2G use the same unit.
Hi, what trans did you use?
