kiya ho gyaaaaaaaa :S
theres alot of alteration needed to mate d16 gear with a f20b...only h22,f22 f23 gears are bolt on...and i wouldnt recommend you any alterations for the gear as the gear ratios wont match with the engine output and you wont be able to extract the full potential of the motor...aur mere bhai gear utarnay charhanay kay he 5k hote hain let alone the cost of alterations...lol
