SRT-4 neons and hondas are using Flexible urethane casting compound .
Shore A 80 Black I orded today from McMasters.com 28.83 shiped and it can do two mounts. Have to wait 48 hours to dry i will update when done. These are some pics of the stock mount if you go down the page you will see how I poured the poly in the mount

This is the site info on the Urethane. I have seen some pics of the honda and srt-4 mounts they look good. Go to mcmaster.com and find products and type in 8644K11 that is 80A little harder than the 60A.

maybe a stupid question but i'm used to it. Did you just pour the poly over the orig mount? or did you dig it out?
 
mount

You dont need to dig it corksport sell a poly insert. That has two side and you push them in so I said what the hell i will pour my own. Its drying now come on 48 hours.

i actually did the same thing, learned it from the teg lol, and i would recommend this one to anyone with downtime. but now i shelled out for a one piece mount when i got the ETD.
 
I've done this before on my SE-R, however after a while, the material cracked. Dont know if it was my fault or not when I poured it and I did do ALOT of hard launches on nitrous. I forget which hardness I had. Overall though, I was very satisfied since at the time there were no engine mount inserts available.
