My question has to do with whether I can use an automatic transmission car as a legal donor for a SM build.
I have a 2002 donor car that was originally an automatic transmission car. My friend wants to use it for a SM build.
When I read 9.1.7.C in the GCR, it says updating or backdating is not allowed.
Does changing the automatic transmission to a 5 speed count as updating assuming I use a NB transmission?
Also I assume I will have to use a VVT motor given that the 2002 originally came with that motor?
I think we will need to change the harness, ECU and diff also. Do any of these violate the GCR if I stay within the correct model year for those items?
Thanks in advance
