The "368 package" is not broken down in detail but Graham Behan, a Lotus Engineer that works for Lingenfelter now, said that the 368 package included a modified cam profile in 2002. (The original invoices for this work come with the car.)

Long-tube headers were installed by Lingenfelter. The headers have air injection tubing installed (required by NJ at the time.) I removed the AIR system and capped the tubes because one of the AIR check valves was causing a clicking noise.

More upgrades:

The car has a Corsa Performance stainless steel exhaust system.

The car comes with both the painted top and the clear acrylic top and the storage bag.

The Pioneer In-dash Navigation System, AVIC-130BT, was professionally installed by Westminster Speed and Sound. It includes an auxiliary amplifier and four new speakers. The original Bose head unit comes with the car.

The car has an aftermarket, remote door unlock and hatch release system installed by Westminster Speed and Sound. The car comes with both fobs.

The Shelby Series 1 wheels were installed in 2011. The rear tires have been on for about 10,000 miles, the fronts for a little less. The original, stock wheels come with the car.

I installed a Hurst Short-Throw shifter, with no reverse lockout

I installed a Hiabeck Line-Lock system. It is connected to the brake lines at the ABS unit behind the drivers seat.

I replaced:
the driver's side window switches
the passenger side window motor and regulator
the oil pressure sensor and connector
the idler pulley
alternator (in progress)
