Innovative Mounts K-Swap Rear Sub Bracket EG/DC2

Innovative Mounts K-Swap Rear Sub Bracket EG/DC2

Every K-swapped EG Civic and DC2 Integra puts a rear mount between the back of the transmission and the subframe, and that mount is only half the assembly. The other half is this steel bracket. The Innovative Mounts 90130-SB K-swap rear sub bracket is the rear mounting bracket out of the 92-95 Civic and 94-01 Integra K-series conversion system, sold on its own for the guy who needs one piece and not a whole kit.

What It Is and Why It Works

The rear mount does more work than people give it credit for. On an EG, EH or EJ Civic and on a DB8 or DC2 Integra, it is the mount that takes the torque reaction every time you dump the clutch, and it is the reason your K20 or K24 does not rock back into the firewall on a hard 1-2 shift. This bracket is what ties that polyurethane rear mount to the chassis at the right height and the right angle for a K-series drivetrain rather than the B-series the car left the factory with. Get the bracket wrong and the mount sits cocked, the bushing loads unevenly, and you chew through it.

Part 90130-SB is the same rear bracket that ships inside their B90150 billet conversion kit, inside the 90150 steel conversion kit built around the Type-S transmission, and inside the standalone 90130 rear conversion mount assembly. That last one matters: if you already bought the complete 90130 rear mount, this bracket came in the box and you do not need to buy it again.

Be clear on what this is. It is a bracket. No bushing, no polyurethane, no mount. If your rear mount is torn or squeaking, the bracket is not your problem. Buy this one when the bracket itself is cracked or rotted, when a used swap came to you with mismatched parts, or when you are rebuilding a kit out of what survived the last car.

Specs

Fitment

This bracket is cut for the factory EG, EH and EJ Civic subframe and the DB and DC Integra subframe. It is not the rear bracket for a 96-00 EK Civic. EK cars use the 96-00 specific rear brackets whether they run the stock EK subframe or a swapped EG or DC2 subframe. It also does not cover the 90-93 Integra DA or DB1 or the 88-91 EF Civic and CRX, both of which have their own rear sub brackets in the Innovative Mounts catalog.

What to Know Before You Buy

The mistake that costs people a week of shipping time on this part is chassis, not position. The 92-95 EG family and the 94-01 Integra share this bracket. The 96-00 EK does not, even on an EG or DC2 subframe, and neither does the 88-91 EF. Read the chassis code off your own car before you order, because the titles across this whole bracket family look nearly identical.

The second thing to check is whether you already own one. If you bought the 90130 complete rear conversion mount, or either the 90150 or B90150 kit, the bracket was in that box. People order a spare without realizing it. Buy this standalone part when the bracket is genuinely damaged or missing.

Plan the rest of the swap while you are here. Hardware is not included, so a from-scratch build still needs the rear conversion mount, the bushing and a bolt kit. 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 pick your gearbox with that in mind. If you are running a K24 rather than a K20A2 or K20Z1, you will also need Honda engine bracket 11910-PPA-000 on the passenger side for that mount to bolt up. And take the standard warning seriously: once a polyurethane mount is bolted down and takes a bolt impression it cannot go back, so test fit everything before you torque it.
