Decat
10 years old and no one has done this yet.
Downpipe out
Precat out
Used the same approach as everyone else; lots of drill bits and lots of force. While the exhaust was out I used the chance to adjust the positioning of the Larini; when it was fitted the cat and backbox were rubbing, now there's an inch clearance.
Gearbox oil change
there's a guide somewhere that lost it's pictures, so i thought i'd take a few for this.
Oil: should be 75W-80. Look for API GL-
x, where increasing x is increasing protection; 4 is general applications, 5 is high torque. I bought the cheapest one I could find with both sets of claims.
Step 1. Remove the undertray
Step 2. Locate the filler bolt, accessed from the top of the engine bay under the coolant tank - loosen with a 8 mm hex head (in picture), but do not remove completely yet
Step 3. Locate the drain plug on on the gear box from under the car; it's under the drive shaft going from the gear box to the NSR wheel.
Step 4. Undo drain plug with 8 mm hex head.
Step 5. Drain oil. Measure the volume that comes out
Step 6. Clean and refit drain plug
Step 7. Attach a length of tubing to making filling easier.
Step 8. Remove the filler plug (Step 2) completely, insert the tubing and start to fill.
Step 9. Get a tea (takes about 10 - 20 minutes per 1 L to fill)
Step 10. Once you've added the same volume of oil that came out, refit the filler plug.
(same volume in as out)
That's it, done!
