Lloyd my name is ***** ***** thank you for your question

The G37 engine does fit in a G25, how ever the ECM and engine harness is different.

Do you have any more questions on this

Customer: replied 9 months ago.
I have a g 25 . I feel like it doesn't have enough torque horse power .. Do u think it's worth it to change the engine or can I do something to the engine it already has for more horsepower.

That is how the G25's feel. It is cheaper to sell it and get a G37. To make the swap to a 3.7 properly you would be at 10k between engine, harness and Ecm
