XE Nova SFi Box Alternatives

[Aamir]

According to the Topbuzz guide of how to fit an XE engine into a Nova,
it claims that you can fit a sfi box from a turbo, without any mods, has anyone tried this before (on a non-turbo engine of course).

What exactly is the function of the sfi box ?

SFi air box:
Early C20XE SFi boxes are small enough to fit without modification, later models had a different shape and need modifying to clear the bulkhead behind, to do this, cut the section out that is required and hot-glue gun a flat section of plastic and make sure its airtight (important). The Ecotec engines do not have a large box on the throttle body, hence no modification is required. C20LET Turbo engines have a different method, hence no modification is required (in fact this can be transferred over to the C20XE engines instead of modifying the SFi box). Also PVD sell a replacement part - a power cap (?95) that fits (looks exactly like the C20LET part).

the turbo bit can't be used

get an early one with squares if you can, fits fine
