LooNy Posted October 22, 2013 Share Posted October 22, 2013 Need a website that's sells a forged kit but I want to keep stock bottom end because I don't want to go down the road of reboreing the cylinders Quote Link to post Share on other sites
mikey4410 Posted October 22, 2013 Share Posted October 22, 2013 that doesnt really make much sense.the "bottom end" isnt the bores. bottom end is crankshaft and at a possibly the rods also. the kits can be got of off tuning developments,a registered trader on here Quote Link to post Share on other sites
triple j Posted October 22, 2013 Share Posted October 22, 2013 people would call that the bottom end, u can get stock size 74mm pistons as long as your bores are good. Quote Link to post Share on other sites
Chris Green Posted October 22, 2013 Share Posted October 22, 2013 If your forging the engine, the bottom end will not be stock. If you are buying forged pistons, you will need to hone the bores in order for the rings to bed in. Quote Link to post Share on other sites
LooNy Posted October 22, 2013 Author Share Posted October 22, 2013 So in the kit it comes with rods, crankshaft and pistons Quote Link to post Share on other sites
russ78 Posted October 22, 2013 Share Posted October 22, 2013 no bud forged kit normally consists of ACL big end bearing connecting rod bearings forged pistons and connecting rods gudgeon pins and a full set of piston rings best to go for a .5 overbore so there is no sloppiness in the bores everything is nice a fresh Quote Link to post Share on other sites
mikey4410 Posted October 22, 2013 Share Posted October 22, 2013 and if your asking questions like the above then i wouldnt get to involved in it all until you have researched alot more ! its a huge thing to take on and not easy Quote Link to post Share on other sites
Chris Green Posted October 22, 2013 Share Posted October 22, 2013 Yeah, if I were you I'd speak to race tech or tuning developments. Or read a lot of build threads and how to's. Quote Link to post Share on other sites
Phil Posted October 22, 2013 Share Posted October 22, 2013 Need a website that's sells a forged kit but I want to keep stock bottom end because I don't want to go down the road of reboreing the cylinders when you say 'keep stock bottom end' you should be say 'keep stock block' as thats what you are meaning. as other have pointed out to replace the rod and pistons with forged items is upgraging the 'bottom end' but as per your request you would need a kit with stock diameter pistons (74mm) to allow you to simply rehone and fit without any serious engine block work. Good luck with whatever you decide to do. if the car is a longterm commitment & daily driver i would put the extra machining costs to the back of your mind and go for 74.5mm pistons and therefore a 0.5mm overbore on the block. if the car is a weekend toy/drag/track etc then whatever slight nastiness may occur from just a rehone it probably wont cause you undue heartache, just the amount your choosing to let yourself in for lol Phil Quote Link to post Share on other sites
