Yea, tis a shame as its a lovely looking design. I spent a lot of time looking at headers and thought about designing and having my own made, unfortunately I cannot justify the cost so went with the ram horn header, the only down side is I cannot run the standard front to rear cross member that you see in the last picture. I am going to try and make a replacement bar so that when I ground out it won't bugger up the sump! I think my original one is missing. I am trying to leave as much stock as possible just to get it up and running, then eventually:
1. Get a smaller battery and relocate it to the space between the passenger front shock tower and the bulkhead.
2. Reposition the ABS module to either where the original air filter (driverside) was located or opposite the steering column above the rear cross member.
3. Relocate the washer bottle or create a shiney new one.
4. Mount a cold air filter box where the ABS module used to be and duct cold air to it from outside.
5. Make a custom full width rad, one half would be the engine radiator, the other half would be a charge cooler rad with a fully ducted front scoop

6. If I do all the above it might be a good idea to all holes filled and paint the bay, I think i'd like to go with a brushed aluminium and black look.
