*** Here are some tips for the RSX Type S Oil Pump conversion This oil pump is found on the DC5 Type R K20A, RSX-S K20A2/Z1.
If you using the RSX Type-S oil pump and are using a TSX (K24a2) or Accord block (K24A4), you will need to modify the mounting surface of the pump to accommodate the lump in the lower plate.
The CRV (K24a1) block you do NOT have to modify the pump. It's a flat surface. You can reuse the oil chain tensioner from your K24A Engine.
The oil pump tensioner from the K24A is the only part that is the same as the RSX. If you have an 8th gen SI K20Z3 you will need to modify your exsisting tensioner or add the RSX oil pump chain tensioner.
The K20Z3 tensioner is the only US spec K20 engine that does not have the RAA piece
