On the 96 Civic we used a C&R RSX radiator with the Spal fan it comes with. 03 Civic Si hoses were used because of the engine proximity to the radiator. The two lower mount brackets were cut off and rewelded into positions to fit the new radiator.
On the DC we used a 03 Civic Si radiator with the stock fan. The RSX radiator hoses were used. We constructed a bracket that bolted to the tow hook mounts and had the 03 Si radiator mount placement.
On the EG we used a 99 Si radiator and stock fan. The outlets are in slightly different locations, so 94 GSR hoses were used. The lower hose had a rather unique shape because we were using a K24A4 from an Accord. So we trimmed both sides of the GSR hose after determining how it best fit. Liker the INtegra, we constructed a bracket that bolted to the tow hook mounts, but this time had the 99 Si radiator mount placement. This setup would also work for an EK.
These parts will become available for sale shortly.
