Working your way up is so important. I am 19 and in a month when I finish building my VL Calais with rb20det it should have >220rwkw. People may say that this is too much power for a 19yo. Well my first car was a VL (NA) and my brothers mates taught me to drive (and the correct ways and places if you need to be a little silly). I drove 15hrs a week on my L's. When I got my P's I drove this car and was a pizza hut driver and drover 25+hrs/week. Then came the calais with rb20 and 130rwkw, drove it a lot and with the minispool had A LOT of respect for it and what can happen, one the spool let go and i bent a control arm,
thank GOD noone was around.
When I get the car back again I treat it like learning to drive again, because essentially getting more power / a different car to me is about learning again. You must be one with your car, know its limits and respect it. But far more importantly you must respect the road and everyone else who uses it including bystanders.
I recommend a Suzuki 800 hatchback as your next car, I had one as a shitter and the top speed was 90km/h ... great car but get in an accident and you will be squashed like a tin can.
Sorry for the life story rant but I just do want to let you all know that younger people will (nearly) ALWAYS be doing silly things. Its the maturity that is needed to decide where/when you will "experiment". A race track is PERFECT!
Good luck with the rest of your life Mines_Datsun because in my opinion you need to move on to a different hobby. I recommend lawn bowls.
