I looked into that a while ago and i dont think you can. The vs ecotec were the first to get a engine cover and it wont fit on vr's. Thats just wot i found out anyway shame though would look good i reckon.
i looked at this aswell for my VP its pritty easy to do. all you nead to do is replace the bolts that hold you fuel rail on with studs, then get any aluminium fabricator to make you a cover that lines up with holes where the studs are and wolla.
