As with the V6 and 4cyl their are differences with the Perana. As many would know the crossmember is different with reversed steering rack but their are other structural mods that let you know.
These aren't advertised but signs from which a genuine Perana can be picked from a fake.
They are much harder to fabricate a fake from than a 4 cyl to V6 swap.
The Perana also has a different setup to what a V8 conversion would and drive differently( not really better)
I do love them they to me are the ultimate.
