Checked with MX5+. They suggested the engine cannot be mounted too high as there is only one position the engine can be fitted correctly. Also if the engine was fitted too high then other components would not line up correctly...like the gearbox etc, would they not?
This is incorrect the engine mounts each (there are 2) have a single 10mm bolt protruding from them that fit into the chassis, however on that side of the car the bolt doesnt go into a hole it goes into a slot, the hole is slotted around 2 inches long to assist in getting the mounts in because its very difficult to manhandle the entire drivetrain and get 2 bolts into 2 holes when the bolts to no line up with the holes until the engine is fully lowered.

red is the engine block, the black squares show how the mounts are positioned with the blue line being the bolts, the pink is the subframe.
Because the mounts are angled you can see that the tip of the bolts are much wider than the base, where it will eventually be touching the subframe when bolted together.
As a result one side is slotted, if the engine mounts bolts are tightened with the engine still supported the mount will be bolted into a position halfway up the slot and as a result that side of the engine will be higher than factory.
Trust me Ive had engine out of these dozens of times and have the exact same issue with a racecar and a whiteline brace.
This next picture shows the front subframe as viewed from the position a driver would sit, you can clearly see the 2 holes for the engine mounts on the sloped surfaces and very clear is that the inlet manifold side is slotted. on the left there is a central hole with a hole above and below to locate lugs on the mounts, on the right you can see the bottom hole for the bottom lug and a large vertical slot to aide engine installation.

From memory, NB strut top bolts are fairly long so should have length to spare?
