MOTOR AND TRANSMISSION
After the test drive I was convinced that the MX5 1800 motor and transmission would be more than adequate. It has an excellent power to weight ratio and the fit was as if it was made for a 7 chassis! Once seated your hand fell naturally to the gear lever allowing for effortless changing.


The standard motor produces about 140-150 HP at the flywheel so it was decided with the motor easily accessible it would be the right time to;
Install a set of performance camshafts.
Port and polish
Powder Coat Custom Parts
New Intake plenum.
These two procedures should produce more low end power and a zippier response overall.  The standard ECU will be replaced by entire LINK G4 ECU package. This is by no means a race motor but will keep me more than happy.

McGREGOR BUILD BEGINS
The build is now a reality with a very comprehensive cost outline from Robert and Mark with flexibility to alter as the build progresses. I was more than happy and with a flick of the mouse funds were sent south that would begin the McGregor Kit Car Project.
The motor selection was still very much in our hands and the 1.6 MX5 that Grant had found was not looking to be that promising. So it was a call to Mark to begin a search for a 1.8 MX5 motor and box. This again saved money as if we found it in Auckland Mark still wanted it shipped to Christchurch to fit the motor to meet the design needs and McGregor’s high standard of manufacturing. I was now beginning to feel very excited at not just the car but the entire way the build was sequentially coming together.
My spare time was now being devoted to internet searches on Lotus 7 builds, wheel and tire options and carbon fiber after market products. This was incredible as the devoted Lotus 7 owners all have common thread of passion for this Colin Chapman little sports car rocket.
