my boy used Allan used HCP in his car and the mounts suck. it did not come close to placing his B16A SIR I right and he later had problems.
I used Place Racing mounts in my CRX for my B16A SIR I motor and so has BJ *Gotin* it sets the motor great but dayum do you vibrate. They are probably the hardest set of mounts out there.
David another crx owner has used Hasport mounts, the motor set in fine and the vibration was less.
Just be prepared to knock a bit into your side wall to get the alternator to fit.
I know you are doing an LS swap, but pretty much this should help.
goodluck!

I see people out there spending money on the car to improve it … If you spend half that effort just working on your driving skills, making you and the car work together as a team, then you’ll go faster – period. To make the car go a second faster on the track takes a lot more energy and money than making yourself drive it one second faster.
