Here's why:
* Different Journal Sizes: The 22R crankshaft has a smaller journal diameter (the part that connects to the connecting rods) than the 22RE crankshaft. This means the 22R crankshaft won't fit into the 22RE connecting rod bearings.
* Different Stroke: The 22R crankshaft has a shorter stroke than the 22RE crankshaft. This difference in stroke would drastically alter the engine's displacement and compression ratio, likely causing major performance issues.
What You Can Do:
* Find a 22RE Crankshaft: The most straightforward solution is to find a used or rebuilt 22RE crankshaft.
* Machine the 22R Crankshaft: In theory, you could machine the 22R crankshaft to increase the journal diameter and stroke to match the 22RE specifications. However, this is a complex and expensive process, and it's not recommended unless you have specialized machining capabilities.
Overall:
It's not practical or advisable to use a 22R crankshaft in a 22RE engine. The differences in design make it incompatible. Stick with a 22RE crankshaft for optimal results.
