CLG Forums Junkie I supported Toymods Location: Perth, Western Australia Registered: December 2002	3K Rally Motor Performance Rebuild to 1400cc Fri, 13 December 2002 13:08 Hi all, Gathering info for a 3K rebuild for a KE20 rally car. To stay within the CAMS guidelines we have to stay under 1400cc, while still retaining the standard block. I'd like to use a 4K crank and rod setup to get the extra 124cc from the crank stroke (3K: 1166cc v's 4k: 1290cc), Can anyone confirm that this will "bolt in" to the 3K block? By using the 4K crank, my calculations lead me to believe that I could bore the block up to 120" to wind up with a displacement of 1396.999627cc (!). Not worried about pistons at the moment, we'll cross that bridge when we come to it. So how far has anyone ever bored the 3K out to? I don't assume I'll get all 120"(3.048mm on top of the standard 75mm bore), but then a 5K has a bore of 80.5mm, can anyone tell me if they share the same block as a 3K/4K just bored out, or are they a different block? I'm not really interested in one off cranks, or expensive options - if the engine lunches itself (did two this year, fortunately they were stockers!), I want to come out with a respectable repair bill! Any other opinions or suggestions are warmly welcomed, also interested to hear other's thoughts on the whole displacement verses revability conundrum! Will do all the given performance rebuild tricks (balancing, blueprinting, ...), more interested in determining the bore, stroke, crank, rod, combination with some thought to pistons. Thanks, Clint!
