will the motor outta 92 civic hatchback fit in a 91 civic hatchback? tranny fit to new motor or use the 92 tranny , also what parts do i need ? what the differance in hp?
also will a 88 prelude 2.0 motor fit to the stock 91 tranny?

 

Yes, the two Civic motors will interchange between the cars. I'm not familiar with the engines available for that year, but as long as it's the same series motor, the trannys will bolt up fine.

Same thing with the Prelude motor....is it the same series as the 91 tranny?
