When did the 1GGTE change from the Gen2 with the yellow ECU plugs to the Gen3 with the grey? (?) Missing parts from my engine and I want to make sure I get the right stuff.

Not sure when the cgange from Mk2 to Mk3 occured but the changes are fairly obvious. Will try and list some of the differences:
Mk3 turbos have a different compressor housing and impeller, its bigger.
As a result the plumbing coming off the turbos to the intercooler is not interchangable.
Exhaust manifolds are different with the Mk2 having a divider on the back manifold. The Mk 3 manifold seem to be much better designed - remember the mk2 runs 7psi and the Mk3 11 psi.
Inlet manifold seems to be the same - however the throttle body is different and the TPS is very different (will not plug up to a Mk2 loom. Idle control is interchangable
The various sensors are different plugs - that is are not interchangeable in the loom - which make me think that they will tell a different story to the computer. Knock and O2 seem to be the same.
Of course the looms are different wth different plug ends to the computer - of interes is that the Mk3 loom will plug into a &mgteu loom - this is something that I will look at further 'cos toyota don't usually do things like that unless they work.
Injectors for the Mk3 flow an additional 10% and have different plugs.
There must be lots of other things.

Hmm, okay. I'm not worried about the turbos because my CT12's aren't stock anyway.
I thought both the Gen2 and Gen3 had the pale green injector plugs?
There was no AFM or ECU attached to my engine, so I just want to make sure they send the right one.

The Mk3 has 2 more connectors on the large computer plug than the Mk2. That is 24 against 22 or 26 against 24, can't remember exactly. just make sure that the computer plugs fit and all is ok.
I think that the Mk1 is also different as the engine check codes refer to a water computer and also diagnostics codes that relate to the water intercooler.

i believe the gen 3 also has some form of external boost controler or maybe it is a boost sensor not sure but they definately have something hooked up to the boost lines that connect to a little box that the gen 2 don't have.

off the gen 3 you have.. the turbos sensing pressure off there own housing and off the inlet manifold you have one hose going to the PS pump, one to the heater solenoid, one more to the fuel reg and one is blanked off. also off the piping between the turbos and intercooler you have a pipe going to the PS pump aswell.
though you may have got one with a boost controller of some sort.

That all sounds the same as the Mk2. I have a toyota engine manual for the 1ggteu/zeu. There is no difference in boost management for the engines. The Mk3 is the same as the Mk2. I also have both a Mk2 and Mk3 with all accessories including looms. I just do not have a Mk3 computer or AFM. If you have electronic boost control it would be after market.

it is on a friends engine in a hilux. Mine definately has nothing on it. That is why he wanted to look at mine. Cause he had it on his and mine didn't. It did not look after market.
I will check it again this weekend and have a better look at it.

The engine manual was bought in japan several years ago - so it is not english. I have however also got a 1ggeu manual tha is in englsh which I use as a reference. I also have a staff member from japan who is a help. I bought the copt of the 1ggeu manual from grant from 6 works. As for the 1ggteu manual I believe that they cost up towards $100 in photocopying - I have not checked it out but will if you are interested.
I am happy to give you any information out of the manuals. I have provided Rod Try with a copy of the diagnostic codes to post as a tech article.

Craig, If you have wiring diagrams and diagnostics for a Gen 2 1G, I would be stoked
