Innovative Mounts K-Swap Passenger Sub Bracket EG/DC2

Innovative Mounts K-Swap Passenger Sub Bracket EG/DC2

You are mid K-swap on an EG hatch or a DC2 Integra, the engine is hanging on the crane, and the passenger side bracket that came with your used mount kit is bent, rusted, or was never in the box to begin with. That is what this part is for. The Innovative Mounts 90120-SB K-swap passenger sub bracket is the right hand piece out of the 92-95 Civic and 94-01 Integra K-series conversion kit, sold on its own.

What It Is and Why It Works

On an EG, EH or EJ Civic and on a DB8 or DC2 Integra, the passenger side of a swapped K-series is carried by two pieces working together: a polyurethane conversion mount and this steel sub bracket. The bracket picks up the factory chassis mounting points and relocates the mount so a K20 or K24 sits where a B-series used to live. That relocation is the whole job. It sets your axle angles, your header clearance, and how close the intake manifold ends up to the firewall. The 90120-SB is the same steel part that ships inside their 90150 steel conversion kit and B90150 billet conversion kit, so you are replacing like with like rather than guessing at a substitute.

This is a bracket, not a mount. There is no bushing in it and no polyurethane. If your engine is flopping around under load and your wheel hop is getting worse, the bracket is almost never the cause, and a new bracket will not fix it. Buy this when the bracket itself is cracked or corroded, when you picked up a swapped shell with mismatched hardware, or when you are piecing a kit back together out of used parts. That covers nearly everyone who orders one.

Specs

Fitment

This bracket is built around the factory EG, EH and EJ Civic subframe and the DB and DC Integra subframe. It is not the bracket for a 96-00 EK Civic, whether that car is sitting on its own EK subframe or on a swapped EG or DC2 subframe. Those cars use the 96-00 specific passenger brackets. It is also not for the 90-93 Integra DA or DB1, which has a separate passenger sub bracket in the Innovative Mounts catalog.

What to Know Before You Buy

The most common mistake on this part is chassis, not side. A lot of people ordering a K-swap passenger sub bracket are building a 96-00 EK on a swapped EG or DC2 subframe and assume the EG part is the right one. It is not. Confirm your chassis code first, and if you are on an EK shell, look at the 96-00 Civic brackets instead.

If you are dropping in a K24 rather than a K20, budget for one more piece: Honda part number 11910-PPA-000, the engine side bracket that lets the passenger mount bolt to a K24 block. Innovative Mounts calls this out in their own kit notes and it catches people every time. A K20A2 or K20Z1 out of an RSX Type-S or an EP3 does not need it. A K24A2 or any other K24 block does.

Two more things worth knowing before you order. Innovative's transmission side mounting is built around the manual K-series transmissions that came in the 02-05 Civic Si, the RSX and the Integra, so plan the gearbox side of your swap accordingly. And hardware does not come with this bracket, so if you are building a kit from loose parts you still need the conversion mount, the bushing and a bolt kit. One last honest warning that applies to everything in this category: once a polyurethane mount is bolted down and takes a bolt impression, it is no longer returnable. Test fit and confirm your chassis before anything gets torqued to spec.
