How hard is it to put j37 into 3rd gen '07 TL type S

My engine has close to 200 k miles and the head has been tapped... Just looking to replace the engine but just wanted to know how hard would it be to put a j37 instead of the j35 it comes with?

anything can be done at a shop....
anything can be done at a dealership...just depends on how much you want to pay...

a mechanic will take off the heads.. and inspect the heads and valves. then either replace the valves or machine the head...then put it right back on

Direct bolt on. Depending if which j37 you use, different things need to be done.

Have the head with a tapped spark plug hole replace and call it done. For these engines, 200,000 miles is pretty young (assuming the engine has been well maintained.

My car is a 6speed tl type s. And yes the j37 bolts right up to an auto and manual 07 acura tl type s. Im currently using a j37a1 short block from 07-09 mdx. 2010 mdx j37a1 alil different but still bolts on to our trannys. My j37a1 from 07-09 mdx had bad headgasket. Warped heads so we ending up using the original j35a8 type s head on the j37a1 short block.

you would know if its bolts on if you actually attempted it. Just like any other long block replacement. Keep original harness and transfer over mounting brackets and accessories. Pretty straight forward swap for 07-09 j371a1
