pistonbroke Posted October 10, 2011 Share Posted October 10, 2011 I'm no expert on them, but I do own a 2005 V8 mustang GT. You mention 2004 onwards having a quad cam 32v 4.6 modular engine, that's not quite right. As far as I know, the 4.6 V8 is a single cam 3v per cylinder unit with VVT. As for tuning, yes, you can turbo them, but the big results seem to come from supercharging them. From quick chats with fellow owners, around the 550-600hp point is the limit for the stock internals. The 5 speed auto is at it's threshold just under the 500bhp mark, whereas the manual box fitted to the GT is considerably stronger. The thing with these engines (witnesses from supra pod can vouch for this ) is the low down torque figure with no lag means they leap off the line, even when bolted to a fat convertible S197. Their top end is no where near the ferociousness of a tuned 2jz, but the fast pick up more than makes up for it. To put it in perspective a bit, my stock mustang runs around the 14.5 mark on the quarter mile. An identical car with bolted on twin scroll charger runs 11.9.

creative Posted October 10, 2011 Share Posted October 10, 2011 My engine is a 5.4lt 32v dohc v8 modular engine that is used in the 'stangs... I thinks as I'm trying to find out tbh. The main problems my engine has had were worn plastic timing chain guides and the back two cylinders would suffer from early wear on the valve guides. This was due to the inadequate cooling at the rear of the head. This was revised in the 06 models. The plastic guides can fail and ford revised these and started making them out of metal. The tensioners also have a habit of failing causing a rattle on startup. A full kit from ford is $2300! Or from America for about $600. Have a look on http://www.fordforums.com.au and see what they are doing with them on there. Quote Link to comment Share on other sites More sharing options...

Post 2004 mustangs had the 4.6 V8, then more recently they've jumped up to 5ltr in the current model. Quote Link to comment Share on other sites More sharing options...
