2020-11-12 - Platform Swap and Engine Swap

Q.
We have a car that was platform swapped. Now we've done an engine swap from another generation leaving all the other swapped bits in place. Can we continue to claim the swapped platform VPI adding points for the engine swap or does the car revert to it's original VPI/platform?


A.
It should be valued as the highest valued model from its generation with an engine swap.  This does allow you to use OE parts from the highest valued model of its generation.

For example, A 1988 Honda Civic EF platform swapped to a 1988 Honda Civic Si now with a 1999 Honda GSR engine would be valued as a 1988 Si with an Engine Swap.  This car would be allowed to use the 1988 Si sway bars.
