^ About time he got a warning. His posted started to annoy me, and I don't moderate here lol.
OP, track days is the best place to learn how to drive as mentioned already. On your first day you will quickly figure out how bad your driving is and adjust to suit. Something as simple as hand placement on your steering wheel. Best to do skidpans/texi as well, as you'll more likely use those skills (for example, controlling a slide if you hit oil) on the road.
My first track day on a wet Oran Park in my crapbox R31 was the most fun I had and learnt so much.
You don't need power for track days. Flush your brake fluid with something decent (Super DOT4 at a minimum), put some decent pads on there (contact GSL Rallysport for some Resma or A1RMs), replace all fluids and filters, etc.
Keep your standard blow-off valve, apart from the lame noise, you have no other reason to get rid of it. It helps with response between gear changes. For boost, stick with standard for now. Once you get used to the car (how it handles, power delivery, fix all the other shit first like brakes, suspension, etc.), you can buy a boost controller (e.g. $30 turbotech) or stick an RB20 turbo actuator (10psi) on there. No point running more than that, reasons mentioned already.
