Kudos on your project. It's looking good!I picked up a '07 GTP sedan with bad timing chains and no power steering when it warmed up for $2k.
I completely went through it replacing the timing chains, chain tensioners, W/P, belt, pulleys, P/S pump, struts, shocks, brakes, rotors, rebuilt the calipers, tires, sway bar links etc, etc, etc.
Thanks for your detailed reply !My GTP has a 3.6 DOHC. Not sure what engine your G6 has, it may have a different PS system? The PS pump is bolted to the block below #1 bank (rear or firewall side) on my unit and it was a pain in the ass to change. It was easier since I had the top of the engine undressed and front cover removed for timing chain replacement.
Anyway I did not have any trouble bleeding my system. I had the front jacked off the ground. I filled the system and let it idle with the cover off the reservoir. I shut it off periodically to let the air rise out of the reservoir. Then I turned wheels lock to lock several times (with tires off Ground still) and system bled out completely with no addition of vacuum or funnel extension. Maybe I got lucky? I didn't change rack so I didn't have half the air to bleed as you had with changing both components.
Ps. Did find my relief valve in pump was score badly causing pressure loss when it heated up.
Thanks for your reply, Shawn. Good ideas !Maybe obtain a spare reservoir cover and you could thread and glue a fitting into it to adapt to different connections.
I can't offer much advice in the way of tuning. But generally speaking, most computer controlled engines attempt to advance the timing as far as possible without causing knocking (pre-ignition). So, if you put in higher octane gas, as I understand it, the engine controller should advance the timing to take advantage of it. That is, you shouldn't need any special tuning for 93 octane.Can anyone provide info on aftermarket tuners for the 3.6? This is s fun engine and combined with the tapshift 6 spd it is s blast to drive (for a cheap car). Would like to tune it for premium fuel. Does anyone have advice besides having s custom dyno gunr? Something plug'n play out of the box?
