zep Posted February 22, 2010 Share Posted February 22, 2010 I don't know much about it, but the dude in Aussie who builds turbo G series gemini engines only puts in bigger valves in the engines made to run 10s or less. Quote Link to comment Share on other sites More sharing options...
RT Posted February 23, 2010 Share Posted February 23, 2010 I put Group 1 big valves in the turbo pinto i used to have. Hard to say you could notice a difference on a turbo engine tbh Quote Link to comment Share on other sites More sharing options...

nick_m Posted February 23, 2010 Share Posted February 23, 2010 I've got no experience with Pinto's, but for what its worth David Vizard recommends fitting the biggest valves physically possible as from a performance view there is no downside. I'd increase exhaust valve more than intake (eg, if you increased intake 1mm do exhaust 2mm) to get more flow out the exhaust and spool that turbo quicker. edit: From memory Pinto's are have quite big bores? If so you should be able to get pretty big valves in there and with some chamber work you should have any issues with valve shrouding Quote Link to comment Share on other sites More sharing options...
