    Supra noob

    Greetings, I got my 90 about two years ago and have loved it ever since, except it needs a bit more power. For years, I had a Grand National with 483 RWHP, but it took corners like a battleship. This is why the Supra, less powerful, but more fun. My plans are to drop a 1JZ into it in the...
