i am doing an engine replacement in my 87 rx7 turbo. the engine in there came with the car and is a JDM engine. the engine i am putting in was involved in an accedent and to my luck the guy sold me the engine while parting it out. i just had the injectors jetted on the jdm engine and i was wondering if i could switch them to the stock engine. the ones in the JDM engine are purple and the stock are red.
would anyone be able to help or is there no way to really tell.

 

all of this is answered in the FAQ section at the top of this section. it would be a good idea to look before asking
