As a parting comment, today’s cars that you have access to are more powerful than cars I had access to as a p-plater. So be happy with what you have and spend your money on keeping your car clean and in good mechanical condition.
Some interesting titbits:
2006 commodore SV6 manual = 195kw pulling 1752kg => 113 kw/tonne
(top speed 245kph, 6.4sec to 100kph, mid 15 sec for 1/4 mile)
1980 HDT commodore 5.0 V8 manual = 160kw pulling 1400kg => 114kw/tonne
(top speed 210kph, 8.4sec to 100kph, 15.1 sec 1/4 mile)
Note the HDT commodore was way out of my price league back in the day… but would possible be P-plate legal for you should you be able to afford it (and if it’s not banned for reasons separate to 130kw/tonne power to weight limit)…
Oh, and later models of the SV6 had 210kw from their V6 (or around 121kg/tonne which is still below the power limit)…
Spending your money on better brake pads and tyres would probably yield much better outcomes than noisy intakes and exhausts..l
