YOW500 Posted December 9, 2018 Report Share Posted December 9, 2018 The TR shop are doing what looks like a good deal for a set of TR6 pistons. Has anyone fitted these pistons, or has an opinion regarding there suitability for a road car? After market con rods are also well advertised, and look like a nice design. Are they better than the original in terms of weight and balance? Your constructive opinions would be welcome. Russell Quote Link to post Share on other sites
Richard71 Posted December 9, 2018 Report Share Posted December 9, 2018 Hi Russell, The TR Shop pistons will be "County" brand pistons and absolutely fine for road/fast road use, though I'm not so keen on their rings, they seem a bit sharp to me. After market conrods, the Max Speeding Rods are the ones you're probably looking at??? I have a set yet to use. Anyone I've ever spoken to about them both professional & amateur only have good things to say of them. With that said, there are few differences between early & later TR6 blocks, I've read here on the forum that one of the engine blocks (can't remember which) requires some machining to allow the large end of the Max Speeding Rod to pass TDC. Let us know what you go for. Regards, Richard. Quote Link to post Share on other sites
TriumphV8 Posted December 11, 2018 Report Share Posted December 11, 2018 I would go for the Nüral pistons. Why? It is a lot of work to bore the block and fit new pistons. No space for some undefined quality and as I did see meanwhile a lot of broken pistons I take the best I can get and the Nüral hopefully have good pistong rings, too. Do not want to say others are bad, because often you do not see the reason why things went wrong, but I simply rely on the Nüral quality. Maxrods are of good quality, fairly priced and light. Balance is really good. Quote Link to post Share on other sites
matt george Posted December 11, 2018 Report Share Posted December 11, 2018 County pistons are absolutely fine, done 40,000 fast road miles in my 2500-engined saloon since rebuilding it in 2012 and had no issues. Stuck with the original rods. Hastings piston rings are well regarded… Jason at TRGB advised these when I was rebuilding the engine from my current project TR6. This time I had the original rods balanced and used them again. Matt Quote Link to post Share on other sites

Balance is really good. When I rebuilt my engine in 2016 I looked at the after market piston suppliers. Nural came into the equation so I asked my local automotive parts supplier where I usually get a good deal? I was quoted £ 105 each + vat for +020's and that was with trade discount? I nearly had to be picked up off the floor! In the mean time I had been under pressure to go from my Engine M/S to go for County Pistons, as I was assured that they are OK as he had already supplied over 1000 sets without any come backs for road use. The only point that he said was that their ring gaps are not consistent. So this is what I did, I have had no problems so far after 5k miles. In fact the car now uses less oil than when it was new!

YOW500 Posted December 11, 2018 Author Report Share Posted December 11, 2018 Thanks every one. It looks like the County Pistons would be good value for a weekend car. Regards Russell Quote Link to post Share on other sites
TriumphV8 Posted December 13, 2018 Report Share Posted December 13, 2018 Oh yes, I know about these problems. The local dealers have their supply partners and if you want to go a different route they offer crazy prices. Maybe the high price comes from the reason they are German products and you asked the the price in GB. Anyway often it is better to investigate a little bit and maybe find another supplier. https://www.ebay.de/itm/382649413042 This is around 60GBP including the tax what in my opinion is a fair price. When I swapped to the VW pistons some crazy people also offered them for crazy prices beyond 100GBP. Normally I get 4 of them for that price! Anyway as I said, County must not be bad because if you open a damaged engine you often do not know, why the piston failed. Also broken piston rings may also have their reason in wrong ignition setting or wrong mixture or compression or a mix of all. Quote Link to post Share on other sites
