tambovski Posted October 27, 2009 Report Share Posted October 27, 2009 Hi! I'm going to rebuild my rusty 2TG and need your help guys )) My 2TG stock block need to be bored up, due to rust and scratches on cylinder walls. I'm planning to install a turbo, so I think it needs lower comp. ratio (about 8.5...8.7:1). I can't find 3TC crankshaft here, so i'm going to use machined to 0.25mm stock crank with new 0.25mm main and conrod bearings. Conrods will be stock too. The problem is pistons. I'm asking some manufacturers of forged pistons, but the answers wasn't clear enogh to make a decision. Can I use ARIAS pistons #3730250 (see attached pic) for my rebuild? Any other adviсe? It's too hard to find 2TG spare parts for me. Some links will be appreciated )) Quote Link to comment Share on other sites More sharing options...

parrot Posted October 27, 2009 Report Share Posted October 27, 2009 Join up on Toymods http://www.toymods.net/forums/ There is a mass of quality info on there about 2TG 3TG builds including sourcing pistons and whatnot. If you try and search 2TG within the forum, the search term is too short and won't accept it. Use google advanced search, and search 2TG within the Toymods website.

styler Posted October 27, 2009 Report Share Posted October 27, 2009 use 3tc pistons with 3tc crank at calculated compression ratios desired, do your own compression ratios after machining to calculate what you need... Quote Link to comment Share on other sites More sharing options...
