HELP!!! why is it smoking?!

[wearurpjs]

Well I have a 92 gvr4 with a s16g.. The problem is my car hesitates and bogs over 2500 grand.. It backfires fast and a lot of black smoke is coming out of the exhaust when the rpms rise.. Also my car is eating up A LOT of gas.. When I rev the motor to low rpms I see white smoke coming out of the exhaust mani or turbo.. Any help would be appreciated! thanks!
