prelude b20 crank in b18c1? anyone know?
i read a fs thread in the marketplace and the person had a "stroked" gsr motor. it was a 89 prelude b20 crank in a gsr stroking the gsr to199?cc's. i am rebuilding my gsr and want to know what it takes to make that setup work and if anyone has info on how well it works, what kind of rods do you use, what mods if any do you have to do to fit the crank in the gsr block.ect. i asked the guy that was on the marketplace and he said that someone else at a shop built the motor and he was not sure about all the details. any help would be great. thanks

you need to do some machining to get the prelude B20a crank to fit a Gsr and I dont know what rods you can use ... I have one if you want it but it would be expensive to ship

Its not the same crank as the b20 crv/ls.... it is a bigger crank and you can use it in a gsr motor. Not sure what kind of machining is required but you get a much bigger motor with this crank.
I know someone that had this setup in his EG a few years back. He also had the rod journals machined to single cam bearing sizes and ran a longer rod with a custom piston, which brought the wrist pin higher up on the piston. He also had a custom skirt on the piston. A lot of work but its worth it if the car isnt a daily driver. Burnt oil cause the wrist pin was so close to if not in the bottum oil ring.
anyone else have info that can tell us about rod/piston combos for a daily driver?

The B20a/b21a crank isn't so strong, and by the time you have the proper machining done to make it work, you might as well just buy a Crower 92mm or 95mm crank.
