New solstice GXP owner, car has been sitting/neglected
Hello all and thanks for having me on your forums, I got a sweet deal on an 07 GXP with 122k miles. It is in rough shape body wise and a few things I am slightly concerned with mechanically. I am looking for suggestions on how to get it back into proper shape. I do plan on autocrossing with it.
Here are my goals right now:
-New battery (Totally dead)
-Transmission fluid change
-Differential fluid change
-Replace cam actuators (Throwing p0013)
-MAYBE brakes (maybe a big brake upgrade)
Here are my long term plans:
-RPM stage 3 kit (Hiflow cat, charge tube, upgraded k04, tune)
-3Bar map sensor
-Big Brake kit
Here are my questions:
-Best manual transmission oil/fluid?
-Best differential oil/fluid?
-What spark plugs should I get if I am going to tune it?
-What could be causing a rhythmic vibration of the whole car (fine for a second, then shaking for a second, repeats indefinitely)? Idle is not rough.
-I hear a rattling ish sound that I have never heard anything similar before, I will have to take a video of it, but do the tensioners/pulleys sound different when they go bad/rust as opposed to most other cars? It kinda sounds like it is coming from the belt system.
-What else should I be looking out for in a car that has literally sat for a year without driving/cranking?
