After having some issues with my Toyota after some work being done on the engine I'm now facing an issue I can't find explanation to. Full story here:

Toyota Avensis Verso D4-D 2002 after turbo & timing belt replacement drives differently

Specifically, I own Toyota Avensis Verso with the engine as in topic. I know that same engine was fitted in several different models (Corolla, Avensis, Avensis Verso and RAV4, maybe something else too), but now, after stumbling on this:

http://www.toyotaownersclub.com/forums/topic/164217-1cd-ftv-d4d-engine-replacement/

where it says:

Turns out the turbo and in fact nearly all ancillary bits are different on the Corolla to the RAV4 but of course it's the block that matters and all parts are being swapped over. Engine is out of the Rav from underneath and was not too difficult to do on the ground with an engine hoist

it looks like it's just a engine block designation, not the full, actual unit. Which means that I'm in a pickle.

So the question is: Is it possible I was fitted with turbo from different model and that's why my Toyota drives differently than before replacement? Can anyone confirm this? And if this is the case what are the reliability and durability of the unit I have fitted now?

Well, after reading until my eyes bleed I stumbled onto this website:

https://garrett.honeywell.com/products/service-replacement/

Which explains very little and yet quite a lot.

It seems that there is just one version of this engine after all, and it was fitted in a very wide range of Toyota models.

HOWEVER.

There are differences between models in details like turbo. But not in a way I was afraid of and what's suggested by my question.

The Garret Turbocharger model GTA1749V is indeed the same for a lot of Toyotas, but versions can - and do - differ. Look at this model: This is the Turbo compatible with my Toyota CLM20 (Avensis Verso)

And then compare it with: This is RAV4 turbo

SO you can see that while they look essentially the same, some angles are different. And, obviously, they can be either adjusted or the engine compartment (and hoses) can take a different versions. Or it's just an aftermarket seller's spiel.

HOWEVER.

When clicking through the links for previous versions (Garret provides them for all retired parts the current one replaces), sometimes specific turbo fitted in CLM20 (Avensis Verso) links to newer version, but fitted in RAV4... Interesting and Confusing.

What's more, in some versions of Corolla and Avensis D4-D (both 66kW and 86kW, for years 2001-2003) the turbo fitted was yet another one - GTA1749LV... And some sellers say they can be swapped for GTA1749V one. Which is weird, because they are quite dissimilar.

I hope this will help another poor soul in similar situation to one I've found myself in.

Ive had 53 reg avensis and still have 05 plate rav4... Same 1cd-ftv engine... Avensis much smoother and quieter. Rav more agricultural noisier even at idle is a big difference. I reckoned there was a cam timing difference at least for more torque from the rav to pull the 4wd system.... A shame i do not have the avensis anymore to compare turbo , injectors and cam timing to see differences.
