Hello all. I am currently under the process of rebuilding my B21FT engine. The engine I am rebuilding was pulled from another car. When I pulled the head I found that i had left two of the valves open (1 exhaust, 1 intake) and inside the third cylinder evil forces of rust had taken over. The cyilinder wall was pitted. I sent it to the machine shop anyway to see if it could be honed. They honed off .004 and still saw pitting so the block is basically useless. I talked to my Volvo shop and one of the employee's informed me he baught Mahle Oversize pistons for $180(B21FT). Then he proceeded to tell me it was the last set in the country. After i stopped crying i began to wonder if it would be possible to install B230FT pistons in my B21FT. Is it possible? The pistons are dished. would i have to replace the crank and the rods? Help! Thanks, David
