lsvtec if done RIGHT is as relaible as stock...that goes for any motor swap...get a hack job done and then you arent guaranteed anything...

i did find this for you though which may be something you want to consider that i forgot about...

Third point:

Cams work in harmony with the static CR via the dynamic CR. When you increase the duration of a cam from stock, you WILL lose cylinder pressure up the intake port. Cylinder pressure is what turns the crank. Lower that cranking pressure during the power stroke and you lower how much the crank is turned. With mild to moderate spec cams, this loss is not so huge and you won't lose power from this cylinder pressure bleed off. But as you get higher and higher on the cam's overlap and duration, the more bleed off you get. You can actually go too big of a cam for your engine..."overcamming the engine".
