Friend bought B20 from well known Swedish Volvo tuner Timo Kormu, he passed away about 10 years ago.
It was Timos latest versions of B20. Somehow OHC engines weren't so popular among rallycross drivers in beginning, and it was late 80's when trend turned towards OHC.
My friend B20 stroker has 92 mm bore and 88 mm stroke.
Head is r-sport casting, but with welded exhaust floor. Valves 46x40 mm. 50DCD Weber's and MotorPuls intake. Cam has 8,5 mm lift. It has 8-bolt crank and M-rods. Pistons are 92 mm KS with std compression height. Pistons comes over the deck height, naturally, so head has space for pistons.
Power? Don't know. It is still in pieces. Has been about 30 years.
