I wouldnt say that it took Dad that much to turn the spanner first time and the resistance was probably just the springs maybe or bit like when you turn the crank over you get a bit more resistance in the position when compression is different etc. presume that your timing belt / marks didnt move though? When I turn the camshaft nothing else turns on mine (belt, sprockets/camgear, pumps and crank etc are all still and just the camshaft has the "float", presumably because it is moving insode the VVTi workings separate to the actual gear/sprocket. Is that the same with yours or does the camshaft rotation turn the belt??

It takes quite a few cranks to build oil pressure so make sure before you do to turn the whole engine by hand with a spanner on the bottom pulley bolt. do it atleast twice so you do a full rotation of the cams. I'd go 4 maybe even 6 and just keep checking your timing still lines up, just good practice really. The oil pressure gauge will not move on crank either it needs to fire before it reads anything and there is no low oil pressure warning light. I pulled my filter off and cranked it until oil came out just to be absolutely sure there is oil going through the system and I haven't done something wrong as it takes seconds of no oil to destroy bearings.
A few people do get rid of the vvti when they turbo this car. The vvti is so dam complicated and expensive it kinda makes sense to dump it for a solid adjustable pulley, TODA make a set but I think they are fairly expensive. VVTI does (apparently) help with turbo spool and if tuned properly can reduce the lag plus you can play with valve overlap at a variety of rev ranges so it can make more power with a steadier curve. I was going to bin mine when I had all the stress of the pulley, they are an absolute nightmare and really make you panic when something goes wrong!
Also, Shanne. You said the pulley eventually gave way and was stiff at first? Did you try just as hard on the exhaust pulley?
The only reason I can think of for the inlet moving is that the inlet timing does change on cranking to help it fire so it might just be not as stiff as the exhaust so that the low crank oil pressure is enough to move it maybe?
