Therefore larger flowing injectors are a must, as is a fuel pump. You will also need a larger MAP sensor, since the stock one can only take one bar of boost. Either a piggyback ecu such as Hondata or a full replacement like the AEM EMS (which rocks) will be needed and a good tuner to go along with it. If you want to boost above the set limit of your turbo (if the wastegate is internal) you will need a boost controller. Appropriate gauges would be a wideband o2 (if you have the money), or an EGT, boost gauge, oil pressure, and a/f gauge if the wideband is not available - are all gauge possibilities, Stronger head studs would be a good idea. Depending on the compression of the engine that you will be boosting you might look into different pistons, or a thicker head gasket (although I prefer stock now). the turbo, manifold, and appropriate oil lines and what not are a given. Buy the trim of the turbo by what you expect out of the engine. And so on and so forth.

It really depends if you want 250 whp or 400 whp or 300 whp or if your just looking for a budget build. Most people that havent riden in a 250+ whp car that weighs 2500 lbs are very surprised and what that little amount of power feels like. I know I was. Good Luck!
