Yep all engine packages without engine bays. Some came as front cuts but no toyota's.
Setup is as follows, no need for ECU etc:
You will need: Charged battery, jumper leads and a small section of wire preferably alligator cliped at both ends.
Connect positive to back of starter and negative to a good metal place on the engine. Then one end of small length of wire to starter switch (usually a spade terminal on the back of the starter) to spin the engine simply touch the other end of the wire to positive terminal. Of course there is the small matter of the Compression gauge too .
Make sure sump has oil and depending on how long the engine has been sitting, it is recommended to pre-lube it first.
Leakdown test, we have a gauge which when placed in spark plug hole, hooked to air line and calibrated gives the result. Essentially it measures the rate at which the compressed air is lost from the cylinder. Simple to do really, just need the equipment and a quick lesson.
As for the CR and CT relationship, Rex would think the CR of the engine would definately have an effect. But how much and if it could be used to ballpark the CR is a different matter.
