This is a listing for a Nissan genuine RB26DETT "05U" engine block.
The surface has been milled by 0.11mm at Tomei Powered, and it is unused since the milling.
Currently, orders for genuine 05U standard blocks are suspended and the delivery date is undetermined, making it difficult to obtain units with the normal bore. If you are looking for a base for repairs or a material for engine construction, please consider this item.

【Product Condition & Important Notes】
During inspection after surface machining, several small cracks were found around the water jacket.
The affected areas are marked with a yellow pen; please be sure to check the posted photos.
Even if no problems were observed during use, cracks may be discovered in RB26 engine blocks after disassembly, cleaning, and surface machining.
While this product did not have any problems before surface machining, cracks have been confirmed at this time, and therefore, we cannot guarantee that it can be used as is.
Whether it can be used and the necessary repairs will vary depending on the intended use, target output, engine specifications, etc.
Please check the posted photos before purchasing, and consult with an engine machining company or specialist as needed. Please make your decision at your own risk.
We cannot accept returns or refunds due to the condition of the cracks, so please only bid if you understand the current condition.
