VPI requests require the year, make, model, trim level, engine size, engine HP, Drive type (FWD, RWD, AWD, 4x4), auto or manual transmission, car weight, and all options.

2020-11-12 - K20A2 block interchange with K20Z3 block

Q.
My team bought a parts car to replace our damaged engine.  After removing the engine and delivering to the machine shop, we found out the block is a K20Z3 instead of a K20A2.  
If we use this block, will it cost us engine swap points?

A.
The K20Z3 block may be substituted for the K20A2 block (and vis-versa) due to there being 0 performance difference.
