this was my first swap back in the day, and its really not that tight of a fit, theres no cutting or anything, it just goes in with the help of new mounts. i loved the swap myself plenty of power. and even though it wasnt the best of ride it wasnt that bad being on normal civic lowering springs. but if i had to do it over again, i would defiantly get better suspension and brakes.go k series if you got the funds
