Hey guys!

I've read a lot about Sierras with Zetec engines, but haven't been able to find a guide or any kind of documentation about it. Can anyone help me with that?
First of all, which Sierra should I use for this project? My first wild guess was the 2.0 DOHC since AFAIK the MT75 gearbox would fit bolt-on with the 2.0 silvertop Zetec. (silvertop it is, because it's much more common where I live, I have never seen a single blacktop for sale). Then I've read that the sump I should have is from the CVH Sierra.
I've learnt that I'm going to have issues with the thermostat not fitting.
Is there anything else I should know? Issues that might cause significant problems? What about clutch and flywheel? I also don't know about ignition.
Plus if anyone has useful docs about the subject I'd be really glad to have them

Thanks in advance, cheers!
