Darton Mid Wet


SKU: N/A Category:


Application:Acura Integra B18A/B – Honda CRV B20

(Darton notes that some B20 Blocks had thinner casting in the cylinder #2/3 area that led to problems with installing sleeves. It is recommended that you use an LS block and install the 84mm sleeves to get a 2.0L displacement as opposed to using a B20 block. It can be done, but it is not recommended.)

Brand New! Darton MID Sleeves for Acura Integra B18A/B & B20 engines replace your factory cylinder liners with high strength iron sleeves, eliminating a weak link in your engine and providing you with the strength needed to get the full potential from your setup without losing any sleep worrying about cracking a factory sleeve and taking the engine out.

MID stands for “Modular Integrated Deck”. If you notice the sides of the top of the sleeves are notched so they mate up flush against each other, providing a full rigid structure when assembled, but still able to be replaced individually if needed. As shown in the photo, the top flange has coolant passages and the outside surface of the sleeve contains “fins” that help reduce heat soak within the sleeve, helping keep the heat out of your internals where it could cause damage cracking, warping, etc.
