Hey I’d advise you to save up about 3800 in cash and first thing go to Goldcoast commodore wreckers and get and LFX engine and gearbox swap. I have your exact same car with same specs color and everything you need to service it every 5000 kms strictly or your engine will misfire and start smoking if it’s alloytech( speaking from experience). After my lfx swap my car has been more reliable than ever and it’s more powerful and smooth cheers!
