JWT QR25DE Balance Shaft Removal Kit (BSR)

Product Review (submitted on February 19, 2020):

Decided to finally remove my balance shaft and install this kit while I was working on an upper oil pan seal leak. I figured while I had the upper oil pan off it would be easier to install this kit (and remove the chain tensioner) with the extra space available. Tensioner was pretty easy to remove and the kit easy to install, but I then found out that I couldn't get the upper oil pan back on with this kit installed because the upper panel sheet is larger than the balance shaft assembly, which causes it to get in the way. So I had to remove kit, install the upper oil pan, then reinstall the kit. Keep in mind you'll have to remove this kit if you need to redo your upper oil pan seal, and those bolts can only be torqued so many times before they will be out of spec. I didn't have any luck finding the PN for replacement bolts yet. If I have to remove this again I might cut back the part that gets in the way so I can avoid future issues.
In terms of functionality, revs up faster and holds the revs longer, I have a little bit of idle vibration that wasn't there before, and a bit more when AC kicks in especially at idle, but it's easy to deal with. Noise increases significantly around 3k for me, so if I want a "normal" ride I just economy shift, otherwise I let it rip and enjoy the speed and sound. I also have polyurethane motor mount stiffeners which contribute to the cabin volume.
