Guest Anonymous Posted October 30, 2001 Share Posted October 30, 2001 i wanna find one of these at a local junkyard, what year/years did this come in? i know it was a diesel maxima but what year? Quote Link to comment Share on other sites More sharing options...
GrayZee Posted October 30, 2001 Share Posted October 30, 2001 I don't know for sure on the years but I do know that it will be within a 81-84 body style. Quote Link to comment Share on other sites More sharing options...
DAW Posted October 31, 2001 Share Posted October 31, 2001 As above, 81-84. There is something to consider when obtaining an LD28 crank. Once you crunch the numbers, it becomes obvious that the LD28 crank transplant into an L28 presents a problem re rod to stroke ratio. The L28 is already all cramped up with no room for a decent length rod to use with the 79mm stroke, much less throw a 4mm longer stroke in there. That is why the LD28 engine has a block 19.7mm taller than the L28, to allow for a decent rod length (140mm). Anyway, I've converted an LD28 to an LD28E gasoline powered engine and I drive the car daily. It performs well (E42 cyl head)and yields about 9.5 or 10:1 compression and gets good gas mileage. I'm anticipating a great engine when I build a turbocharged one. Later, I'll go for an overbored LD28 block (I suspect a big overbore is possible), some rods in the 150's length, and a P series head. The point is, you may be able to get a diesel engine for the same price as a crank, and don't write off the block as it holds great potential. By the way, Nissan Comp told me it couldn't be done. It can; drill head bolt holes from 10mm to 12mm and use BMW headbolts, L20B front cover, reuse LD28 head gasket. Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted October 31, 2001 Share Posted October 31, 2001 wow, i did not know that, i am building a stroker turbo project, i have Top-end performance spec JE forged pistons (8.2 CR, 88mm, flat top piston with high high coatings) i plan using the l24 9mm rods and the LD28 crank. to put in the f54 block with p90 head. but i want it run a t61 turbo for more of a race application. i'll get pictures eventually..

DAW Posted November 3, 2001 Share Posted November 3, 2001 What I'm suggesting is that you look at the rod/stroke ratio. Presently yours is 133/83 = 1.602, which is low. In the diesel block, if an overbore to 88mm were possible, the applicable rod length would be about that of a LZ22E, 148.6. This would yield a rod/stroke of 148.6/83 = 1.79, which is a significant increase. I'm going to try anLD28 hybrid overbored from 84.5 to 87mm.

Guest Anonymous Posted November 3, 2001 Share Posted November 3, 2001 It's possible that I may give up on building my stroker turbo engine in which case I will have a freshly rebuilt T3 water cooled turbo, polished LD28 crank, L24 9mm bolt rods, F54 block race prepped but no machine work done, P90 and P90A head, polished valves, customized intake manifold with 65mm throttle body fitted to it, 440cc/min injectors from toyota supra turbo, SS mandrel bent down pipe, starion intercooler with custom pipes, Borg warner T5 transmission in good shape, and probably some other parts laying around. Like I said I'm not 100% sure on giving up, but am considering it, so let me know what you're interested in and I'll talk a price with you.

Guest Anonymous Posted November 3, 2001 Share Posted November 3, 2001 Tony, I am interested in some of your parts. Let's talk I will email you off line. Might want to put this in the "buy/sell/trade" forum, though. Quote Link to comment Share on other sites More sharing options...
