DAW Posted October 14, 2002 Share Posted October 14, 2002 LD28 rods also use big, floating wrist pins. DAW Quote Link to comment Share on other sites More sharing options...
Bob_H Posted October 14, 2002 Share Posted October 14, 2002 Uhh, minor point. The diesel rods are NOT a performance option. They are designed to take the massive compression of the diesel,(upwards of 20:1), and are much heavier than "normal" rods. (discussing in general terms). I have not personally seen the nissan diesel rods,(DAW has) and cannot say how much heavier/larger they are specifically. The crank works, but I wouldn't use the pistons or rods from the diesel. -Bob Quote Link to comment Share on other sites More sharing options...
yo2001 Posted October 14, 2002 Share Posted October 14, 2002 big as in 22mm wrist pins? I can mate with my RB26DETT pistons to make a hybrid motor. I can always use stout rods Bob It's worth a try. Wouldn't it be a ideal rods for a force induction rods? hint, hint Quote Link to comment Share on other sites More sharing options...
DAW Posted October 14, 2002 Share Posted October 14, 2002 Big as in 23.5mm pins. It has 9mm rod bolts and a wider beam than the other L series rods. It most closely resembles the 12100-B2501 Sports Option NISMO rod except it has bolts/nuts vs 12-point bolts tapped for into the rod. See pg 39 of Honzowetz's book "How to Modify..." the rod shown is the 148.6mm version but looks otherwise like the 140mm version (which the LD28 resembles). I can't find my postal scale but it is not a massive, heavy unit. As Bob H mentioned, they are made to handle 22:1 c.r. I've just started yet another project where I'm building up an LD28 overbored shortblock (to mate an L6 P90 head) using a Mercedes-Benz 87mm piston (big floating pin, strong piston) to fit to the LD28 rods, and milling down the head to the compression ht and shape I want. Has anyone welded injector bungs and t.b. flange onto that LD28 intake manifold? Hood clearance looks like a problem but performance potential looks like it might exceed the stock L6 f.i. manifold.

yo2001 Posted October 15, 2002 Share Posted October 15, 2002 Hey DAW, it's it 23.5mm with a bronze bushing? If not then I can bush the rods make up the difference. If you can a pic of it, send it to me. I'm guessing it's like FJ20DET rods. Those are real stout Quote Link to comment Share on other sites More sharing options...
DAW Posted October 15, 2002 Share Posted October 15, 2002 yo2001, I don't have a web site but I could e-mail an attached photo. I put an L24 rod next to it for reference. I was wrong on the pin dia., it's 25mm not 23.5mm. The outer dia of the bushing appears to be about 28mm. I don't know the accepted limits on reducing the bushing bore (e.g. to 22mm). I've got the opposite problem and have to go from 25mm to 26mm for the Mercedes pistons. BTW, if you get the photo OK and have a website maybe you could post it for others? Thanks.

yo2001 Posted October 15, 2002 Share Posted October 15, 2002 send the pic to me DAW. my email yo2001@charter.net I don't have a website, We'll need to ask somebody else for that. Thanks Quote Link to comment Share on other sites More sharing options...
