The Toffinator Posted December 13, 2014 Share Posted December 13, 2014 Idea floating in my head today regarding the above engine components... I have these bits sat in my shed doing nothing, So if its possible i will do something with them. I Know a 5EFE Rod is longer than a 4EFE/4EFTE RodI Also know a 5EFE Crank is longer throw. However what im thinking of in the simplest terms using these parts would just make a DE-Stroked Engine, And the pistons would not reach the correct TDC.So if you wanted to could fit custom pistons, Or custom rods, Or what im thinking off, Decking the top of the block! Main thing that would stop me doing this is the rod journals and main journals though. I know one of them is different and i have a feeling its the mains. Is there a way around this? Or could i just use 5E Rods and bearings on the 4E Crank, With 4E Main bearings? Or would i have to Use 5E Bearings? Or is it not that simple? I know people will say dont bother etc but these bits are surplus. And if its doable, even if i have to do a bit of block machining to fit the crank. Or shoot me down in flames and tell me the crank mains are smaller on the 4e crank so wont fit in the 5e block. (Unless i used oversized bearings? Lol!) What do people think?

The Toffinator Posted December 14, 2014 Author Share Posted December 14, 2014 Just had a quick look myself and found that the Mains are different, Does anyone know if its diameter or width? If its diameter and only by so much surely oversized bearings could solve this? Quote Link to post Share on other sites
AdamB Posted December 16, 2014 Share Posted December 16, 2014 The 5E journals are actually wider, rather than diameter mate. Quote Link to post Share on other sites
5e colin Posted December 16, 2014 Share Posted December 16, 2014 great idea but your better of with a 4e block with 5e crank and custom rods sleeper 5e :) Quote Link to post Share on other sites
The Toffinator Posted December 16, 2014 Author Share Posted December 16, 2014 Ahhhh wider is no good really then is it :/ And i only have this choice really or I would! I have a 5e crankshaft but it needs 0.75 bearings, Which I'm unsure off! Quote Link to post Share on other sites
