Well I can't bag the Boss 260, it's been very relaible considering what i've done to it, as far as timing chain issues, if mine was going to let go it would have by now BUT i do think it's a bit doughy down low compared to our other cars but that will be overcome in the next couple of months.
We own the other brand and my BA XR8 ute and my ute is still more comfortable than the other two for long hauls and it's dumped. Dave

ok, i work for a ford dealership, and the problem with boss motors comes down to the servicing. 15,oookm is a long time between oil changes, and a lot of owners wont make the first oil change till almost 20,000.
The compression rings wear prematurely, and normally cylinder number 5/6 ends up with less than 120psi compression.and an engine rebuild on a boss isnt cheap...close to $8,500 So frequent oil changes and good quality oils like mobil 1 or castrol edge is a good start and all boss motors from about 2004 onwards come out with the revised timing chain tensioner

yeah but there is still a fair few cases occuring,its not a fault with the rings it just comes down to lack of maintenance.As a lot of XR8's get driven hard, they need frequent oil changes, because of the tight tolerance of today engines, the smallest particles of carbon can distort piston rings

For sure. But I remember FPV actually changed what type of rings they were using.
As with any engine, don't look after it, and it won't last.

Nope still 15K, with an optional 7500 oil change. You should really do this yourself anyway. No need to pay Ford uber-$ for an oil change.

This is all a bit scary for those of us who would like to buy a second hand XR8!
If that first oil change was at 15,000+, who knows what sort of grenade you've bought a few years down the track?

both the 5.6 and the 5.4 are great motors each in their own respect. I would much rather own a TS50 though because in another 10 years they will be worth more than a mk2 BA XR8, and have awesome low end power. which is what I personally like. Considering Ive seen ts50's for sale around 27-30k (auto-manual price) they are a pretty schmick car for the money. biggest plus is the handbuilt engine... just to name a few bits:
The 5.6-litre V8 is built at Tickford using a modified “Windsor” block, an all-new crankshaft, ported cylinder head with high performance springs and valves, billet machined connecting rods, lightweight pistons with fully floating pins, a revised camshaft profile, an 82 mm diameter throttle body, three-piece high flow inlet manifold and conical air cleaner with dedicated mass air flow (MAF) sensor. check out this guys site for a clip of the exhaust note of one with a custom exhaust. http://www.nz440rt.com/TS50.html 700 rwnm with exhaust and stealth tuner (540 rwnm @ 1500 rpm)!! you cant tell me a boss can run with that...

after oil changes it goes and comes back you say? if it's a deep sounding tick it could be a gummed up lifter.wat type of oil are you using?
