Idrees Posted December 14, 2015 Share Posted December 14, 2015 We sell these. Drop me a PM for info/prices please. I have a set waiting for my new engine too, just not enough time to build the thing! Quote Link to post Share on other sites
animal GT Posted December 29, 2015 Share Posted December 29, 2015 What kinda upgrade are these? Specs? Price ? Fitment please Quote Link to post Share on other sites
Phil Posted December 29, 2015 Share Posted December 29, 2015 Half a mm bigger I think ?Not sure what sort of bhp they release But based on other performace turbo engines ( rather than any in depth knowledge of flow characteristics) it's the exhaust valves that are holding things back in the stock setupPhil Quote Link to post Share on other sites
AdamB Posted December 29, 2015 Share Posted December 29, 2015 Realistically the off the shelf ones are still too small, need to be at least 2mm oversize, but I'm unsure and doubtful a stock head would be able to accept that much without some serious work. Quote Link to post Share on other sites
abbott Posted December 29, 2015 Share Posted December 29, 2015 I use these valves and was the 1st production set built for my engine build. they make a huge differance with a big port and polish job and the 4e/5e heads do benefit having these fitted. Im sure the traders get suplied by who developed these so dont want to step on there toes from who People buy them from Quote Link to post Share on other sites
