I'm not in the slightest bit technical minded so please bear with me!!
a) Where will my engine number be located?
b) Have today discovered I have a F13 gearbox, is this the close-ratio or wide-ratio gearbox used in Si's?
c) Is 'comma' engine bay cleaner any good, or does it take several days for a bay to be cleaned?
d) Is it worth getting 'performance' ignition leads and sparkplugs?
