Grand Prix LS1 Intercooler - Contents Under Pressure

Part III: An Intercooler Installation Extravaganza!Last issue we covered ripping apart our Grand Prix X-P and installing our ZZPerformance Stage 2 Intercooler Heat Exchanger System, as well as our Stage 2 intercooler pump. In this episode, we will wire up our pump and install the actual intercooler core and LS1 Throttle Body Conversion Kit! The potent X-P has already produced 405 horses prior to this upgrade and we can't wait to see how much more horsepower will be made. But first, we still have plenty of wrenching to do so let's get to it.

Well that's just about all the room we have for this installment, check back next issue when we will tackle the installation of new fuel rails and a new custom exhaust!
