Kyle, If you have some ramps it won't be too bad, but if you have no way of getting underneath the GS it might be a PITA. You'll need to loosen the 2 bolts underneath the GS holding the WERKS DP to your frame. That will allow the top of your DP to move and clear the bolts holding it to the turbo. You might have enough flexibility in the DP to do it without removing those bolts underneath, but I'd be afraid of bending the bracket underneath the car. As far as the turbo, the only real PITA part is leaning over the side of the car for a little bit. I don't know about you, but my back gets sore as Hell doing that......lol. You'll have three 10 mm bolts holding a heat shield around the turbo. IIRC, two are pretty easy to get to on the upper part of the shield, then there is one between the heat shield and your firewall. The rest is pretty easy, just a few nuts/bolts to pop the turbo off the exhaust manifold. It's just that time where you're leaning over the car that is the real PITA! Just place a towel or something over your quarter panel so you don't scratch it while leaning over the car! Any questions feel free to PM me.
