This will not fit without complete custom fabrication of motor mounts...and thats just mayb 10% of all the custom wrk that has to be done to get this motor running in our cars...
Just buy a used TSX. They're pretty cheap for what it is and you can easily get one fully loaded with seat warmers and navigation for under $15k with under 100k on mileage.
its doable. expensive. but definitely can be done by someone with the proper tools and experience. check out dreman's build thread. he's doing a turbo K in his 6th gen.
