Who sells a 3 liter “kit”?
Arizona Z’s (phone 602-844-9677) latest catalog features a 3.1 liter kit. The crank is a custom made from 4340 chrome moly. It has a 83mm stroke, the same as the diesel crank and sells for $2395. The pistons likewise are custom made. They are forged, 89mm in diameter, with a flat top (no dish) and have a zero deck height when installed with 240Z length rods. The piston pin is a full floating design that is 1mm smaller in diameter than a L series piston. The pistons run $95 a piece (includes rings). They also have chrome moly rods that are lighter than the stock 240 rods. These cost $169 each. Total kit cost is $3979. I would think that you can utilize a used diesel crank and used 240Z rods and save some money. They will sell you the pistons separately. The rods would have to have a bushing pressed in by a machine shop and then machined, but this is a fairly standard procedure. They are also working on a 3.2 liter kit which will feature another set of custom pistons and rods and a crank
