  1. Update... It appears that I have been a really bad friend! My mate sold his farm a couple of years back and I just found out. He is over 700mls away so I can be excused for that. I spoke to the new owner, and all surplus "junk" was removed when they bought. They do have a Nissan patrol with a LD28 for sale, but cannot seriously consider that option to just part out a block and a crank. Apparently, the V57 was not an official import, but a number of these motors were brought in for conversions in Land Rovers. The net is littered with people talking about this conversion, but the posts are generally 5+ years old. I will post a couple of ads on some of the local 4x4 forums to see if I get any bites. @WhitleyTune, yes the idea is to drill out the head to accommodate the larger bolts. Ran it by an engineering shop and they weren't too concerned.
  2. @inline6... That block is definitely different. Mine has the external ribbing on both sides.
  3. Thanks for the upload lesson. I have attached a picture to test. If it doesn't appear... I'm still retarded. Ok, it appears that it has worked. The caption for this picture, in case anyone hasn't read the kak previously is this. Testing the rod clearance in my 89mm x 92mm stroke LD28 block. Seriously considering stretching it to 93mm stroke. Would require further trimming of the piston crown. 94mm is totally possible but another piston with a compression height of around 31mm would be required. To take 3mm off the top of a KA24 would be pushing it. a 2.5mm trim and a 2mm gasket would get it there too. That will give a genuine 3.5l (3508.72cc) Bear in mind this is with the std 89mm piston. 89.5mm will bump to 3588cc and for those with nerves of steel (and deep pockets) a 90mm cut will deliver 3588cc.
  4. It appears that my ability to upload pictures is severely retarded! I have uploaded a batch in my gallery section. If someone can give me a clue how to load a picture into this section it would be greatly appreciated!

    92mm Stroker

    Various bits of my 3.4 stroker build. Slowly slowly... catchy monkey.
  6. Howzit guys. I know this has been a while... but I warn you that this is not a mad panic, so progress will be slow as I start to tear down my car for a full rebuild. (Another story for another day). I am going to attempt to upload some pictures to show where I am so far on this build. Block has been bored to 89mm. I could have gone to 89.5 safely, but decided some insurance was a better idea. The crank was in the process of being machined, when the machinist was hit with bad health and nothing happened for a while. While this was happening I decided to push the envelope a little further and explore a 92mm stroke over the planned 90mm stroke. As this was going to put me in "unknown" territory and as I have already been shot down for asking "sensitive" questions, I decided against it and throw a simple pattern together to test possible/probable interference issues in the block. (LD28 block for those who have forgotten). The results were better than expected. Not only was the pattern extremely accurate (luck more than anything) but there is zero clearance issues. It gets close in places. I would guess in the region of 1mm, but that is easily sorted out. The piston (KA24) will be trimmed to the required height depending on the head gasket. Probably in the region of 1mm which will remove the .7mm dish. I measured at TDC and got a positive reading of 1.89mm. The reading at BDC was 90.21. This gives a final stroke of 92.1mm. (I was stoked with the accuracy... all things considered). Now to get the crank completed..... I will keep posting updates. I must add that the point of this build is to see what is possible with a "modest" budget. It is not a substitute for a purpose built race motor (in a crate) from one of the big names.
