Here's what I know. A 1,6 non turbo weighs in at 250#. Any of the following are 100% mechanical and require the same amount of wiring1.5NA1.6NA1.6TD1.9NA1.9TDThey are also all the same size (not sure about the 1.5)as the 1.9 is just a bored and stroked 1.6. The only differance is the turbo and associated partsThe 1.9TDs tend to have crankshaft failures if you don't keep an eye on them.I have an engine out of my car so if no one gets you an answer by the weekend I'll go out there with my tape measure
