Difficult job replacing the clutch, try Mr Clutch ~£350
Ensure the clutch pedal will be a progressive action when you select a replacement A new stock 165 clutch won't slip at 244bhp/205lbft A new stock 205 clutch won't slip at 300bhp/300lbft |

Finding one may be a problem New from Toyota they are ~£1250 Use the original 165 mounts otherwise the gearbox will sit too low in the car Use the original 165 driveshafts Direct bolt on |

Long term reliability may be a problem. Why not try another oil but with improved protection e.g. SMX-S ? |
