Shuyun Posted December 11, 2007 Share Posted December 11, 2007 I have just purchased a Maxima LD28 complete long block for the crank. I have been reading about the block for use in my next build up. The information I can find says a 1.5mm or 86mm over boar is the limit of the block. The center line spacing is supposed to be 96mm so is it possible to sleeve the block it a set of 90mm boar 2mm thick cylinder liners with a 2 mm spacing between cylinders?

Shuyun Posted December 11, 2007 Author Share Posted December 11, 2007 I have not decided who to have my machine work done by yet I am still assembling parts. I have not decided on how much I am going to push the limit on bore and stroke. I have been planning on an 88mm bore and an 83mm stroke with a F54/P90 combo with a blow trough carb setup looking for 300hp. I was just asking if a bore of more than 86mm was possible with sleeving on the LD Block. Quote Link to comment Share on other sites More sharing options...
ezzzzzzz Posted December 11, 2007 Share Posted December 11, 2007 I believe your limitations are 86mm without sleeving. I'm waiting on sonic testing for my LD28 block before custom pistons are selected and ordered. Sleeving was a consideration for me too. Once I realized that the sleeves alone would run about $100 a piece, plus the machining cost involved, I decided a 2.8 to 3.0 would serve my purposes well. In the long run, I'd be dollars ahead just dropping in the LS1 sitting in my garage. Quote Link to comment Share on other sites More sharing options...
OlderThanMe Posted December 16, 2007 Share Posted December 16, 2007 You could really go a good bit larger than 88mm with sleeves. Just have sleves made that have flats on the sides. Dalton is a very good custom sleeve manufacturer. Let's just say you can go stinkin HUGE with sleeves. 89mm has been done on a N/A LD block before. The video of it is hosted on Google video somewhere. Quote Link to comment Share on other sites More sharing options...
TABrinn Posted January 10, 2008 Share Posted January 10, 2008 I've been interested in a LD28 build up for a while but didn't know so many people were trying it out. How well does it fit in a Z or ZX (its a little taller)? Are the bell housing bolt patterns the same as the L28? Quote Link to comment Share on other sites More sharing options...
