Bmw swap rules


Recommended Posts

I'm looking to clarify something as we just put a connecting rod through the block testing for Daytona,  our car is a 1992 bmw 325is pre vanos.  Finding another engine is proving to be difficult but running cars seem to around.  If we went with a 1991 or 1993 engine do we suffer  the 50 points for a swap?  The motor is the m50b25 and the ecu is not the same as the 1991 or the vanos version in 1992.  So the engine will be the same M50b25 but may jump a year?   We don't want to cheat or not claim anything but don't want to get hit with 50 pts to put the same hp engine back in the car with a suitable ecu.  If that is the case we will just have to wait to find the right engine, 26 year old donors are getting harder to find.  Does the year make a difference if it's still a m50b25

No.

 

This should be confirmed by the VPI calculator which when I checked indicated the same 500 pt VPI for 1991-1995. So any M50B25 should be good to go without penalty.

Assuming this is an E36 chassis.  So long as you use another E36 motor (m50b25, m52b28) you can classify the car as that specific model using the VPI table.

This procedure is covered in the rule book under the platform swap rules...

 

4.6. PLATFORM SWAP

4.6.1. As an alternative to an engine swap, teams may qualify for a platform swap. A platform swap is defined as replacing the original components with all the components from the same chassis family (i.e. – 318 to 325 BMW engine swaps or 2.8L to 5.7L Chevy Camaro). To qualify as a platform swap, all of the differing vehicle components must be swapped to match the new platform. This includes engine, transmission, differential, suspension, fuel tank, etc. The VPI of the car will now be based on the car and engine combination as presented to tech, regardless of what engine may have been installed originally. No swap-surcharges shall be applied to platform swaps.
