No

The input shaft is longer and narrower on the 4 banger. It is also alot weaker and first gear is way low.

This will cause another debate but,. The four banger trans will push up into the crank and can cause main bearing failure. I would never use the trans for that single reason. Yes you can make it work but why. You will just beat it apart and need another one later on. To me thats money wasted.
