CA18DET bottom end query...
As per title,my question is fairly simple i hope and anybody who has done a full rebuild of a CA18DET should be able to say yes or no! I am building a CA18ET but using uprated parts from a DET as the bottom ends and basically the same,however the conrods differ somewhat. The standard ET rods have a hole in the bigend bearing and a hole in the casting of the big end of the rod with a restrictor to produce the cooling oil mist for the bottom of the pistons,however the new forged rods i have for the DET do not have this. Although the design looks like the shape of the side of the rod may serves as means of shooting oil to the underside of the piston for cooling and gudjon (sp?!) pin lubrication. My question is simple after i have waffled on setting the premise, do CA18DET engines have a seperate oil squirter facilities or not?
hope that makes sense! any help will be greatly appreciated. Thanks in advance. Ben ____

im fairly sure the DET has oil squirters in the block itself, some machine companys should be able to fit your block with the squirters, i know Silvia Engineering used to advertise it, but they dont exist no more.
im afraid thats about all i can answer, but like buses, another member will be along soon, that im sure will have better knowledge of this. Not sure if this is the CA18DET or the SR20DET it dont say on the description, and i have seen neither. http://media.photobucket.com/image/c...lsquirters.jpg And this below is taken from the S13 CA18DET workshop manual.

Det rods are thicker in section and use a larger diameter gudgeon pin too, so you cant use DET rods (or aftermarket versions) with ET pistons, has to be DET spec pistons too. Win, win really, better pistons and stroger rods.
crank and big end bearings are the same so will fit.
