280zg Posted October 18, 2006 Share Posted October 18, 2006 I have seen some info somewhere on the net... Of people converting the diesel engine RD28 with a RB head, from a RB25/26DET(T). Does anybody know some more of this? http://en.wikipedia.org/wiki/Nissan_RD_engine The RD28 is more available in europe, they came in the Laurel and Patrol, ca -90 models +/- some years. And, I was thinking of get a head from a RB25DET, and put it on the RD28 engine, building a RB28DET!!! Could someone tell me if this would be a good engine, or is there some reason for this engine to break down, or give poor power? Would the diesel crank or other internals be no good? The wikipedia don`t say if this would be a bolt on head... I already have a autronic smc in my z, so there would be no problem in controlling the engine. Also, what kind of transmission would fit this engine? The best would be if an transmission from a RB-powered skyline would fit. Quote Link to comment Share on other sites More sharing options...
tfreer85 Posted October 18, 2006 Share Posted October 18, 2006 Internals and such might be a problem but your biggest problem is going to be the head. I've never seen an aluminum diesel head and most are going to be cast iron. If you wanted to just slap a turbo on the current diesel. Would be much easier to do. It also depends a lot on how much HP you want to make. Tyson Quote Link to comment Share on other sites More sharing options...
280zg Posted October 18, 2006 Author Share Posted October 18, 2006 No, my point would be to make a petrol engine of a diesel bottom with a gasoline head. All injection and ignition! From a RDiesel28 to a RB28. No dieseloilburner... Power? How much power would a RB28DET engine make? 500hp++? Quote Link to comment Share on other sites More sharing options...
alexideways Posted October 18, 2006 Share Posted October 18, 2006 Well, I'v read about that somewhere too but can't remember where. I do remember that the tranny is compatible and the head bolts right up. The block is heavier though, to witstand the high compression of the diesel stroke. Anyways, I'll try to find that site again and I'll send you the info. Quote Link to comment Share on other sites More sharing options...

240zwannabe Posted October 26, 2006 Share Posted October 26, 2006 as far as internals, does anybody know if the L28 rods and piston would work? maybe the original crank would accept them? this could be a serious consideration for a future build.
