I have a BRF 200r4 core with upgrades that I would like to sell. The transmission has an aftermarket forward drum, input shaft and larger billet servo. The transmission was reliable in a low 11/high 10 sec car, but when I upgraded the motor and turbo and added about 100hp it broke the OD ring gear. The transmission will need a new OD ring gear(aftermarket billet is $185, stock would be around $25-$50) and I would recommend a general freshening while it's apart. Please check the pics to see the overall condition. $485 for the core with the upgraded parts. I will ship the transmission at the buyers expense. Thanks
