To be honest, Im not sure of the difference between 88260 and 88261 heads. I know the difference in cam covers though. But I know the 88260 was avaliable with solex carbies, and EFI as well. You will find the EFI manifold and Carbie manifold is differnt by one bolt. THat will show what the head had on it originaly.

I've got an 88260 2T-G with no sticker on the timing cover, dual sidedraught carburettors, no EGR, no mechanical fuel pump (blanked off) and an engine fan. Sounds like a bitsa engine, theoretically 88260 should have carbs, mech. pump and engine fan, or elec pump, thermo and fuel injection; not a mix of both!
Jonny suggests that the flange pattern on head can detirmine original fitment (EFI or carburettors) what am I looking for to detirmine?

Go to my webpage and see what I say there, although it is not 100% correct and I have to update some things on it still.

If you give me a picture of the carbs I can say what generation they are, roughly, and give a better idear if they came on that engine.
All 2T-G engines came with a fan. The oldest came with a fixed 4 blade fan (similar to old 4K engines). This was 88220, 88222. From about 1977 (88260) they all used a viscous thermo fan. Not electric, just a normal fan on the engine but with a thermo-clutch. All new north-south toyota engines come with a fan of the same design to this day. It has nothing to do with efi or carby. These fans where either 5 or 6 blade. Also came on 3T motors.
A EFI motor will have the fuel pump hole blocked of with a plate. Your engine sounds like it was a EFI one, but only if the fuel pump plate was always there. Anyone could have just bolted that on.
The EFI that came on the 88260 was one of the first EFI engines toyota made. It used EGR, and did not have "EFI" on the manifold like the latter ones did. I have not seen this manifold being used in Australia, so maybe yours had efi but someone through it away. All the efi manifolds I have seen being used are the latter 261 and 262 ones, non-egr.
Before people could aford aftermarket computers, alot of the 2T-G's imported had the EFI stuff chucked out in favour of carbies.
