A thicker hg gives lower comp ratio and better for forced induction (i.e turbo/ super charger)2. i have no idea, but i dont think you should be able to go to wrong. I'd pay my local tuners because he done a more than exelent job of my dads car, (made alot more torque than i should have been )3.uprated cam springs allow you to rev higher without your cams " bouncing", see my thead here: http://www.ukstarletclub.com/forums/index....showtopic=11624thanks, if someone with more understanding of starlets could correct me on anything, please do...

StarletRick Posted May 19, 2008 Share Posted May 19, 2008 uprated valve springs are to stop valve floating. it all depends how high you rev the motor. Quote Link to post Share on other sites
