Does anyone know the model number of the 4 speed auto used in the xr6 turbo's? The reason I ask is that when the xr8 (500nm) and gt (520nm) were introduced there was a 6 month wait because btr & fpv designed a whole new box (internally) called the m97-019 because the box used in the xr6 turbo (450nm) and 5.4 3v (470nm) wasn't strong enough. http://www.performanceforums.com/forums/archive/index.php/t-67140946.htmlSo I guess my real question is are the FPV/xr8 auto's any stronger than the ones used in the xr6 turbo, and can they be/has anyone fitted one to an xr6 turbo?

Looking forward to seeing these things but was kind of hoping they'd use the real new boss engine, the 6.2 sohc (the new block with wider bore spacing) that they replaced the 5.4 with in the states in the F150 raptor truck, rather than the coyote (from what I understand is a bored out 4.6). 309kw @ 5500rpm and 588nm running 9.8:1 compression in truck trim on any grade fuel http://www.meadowlandford.com/ford-6.2l-engine-specs.htm, if FPV had of bumped the compression or even just changed the cams or tuned it for premium I'm sure it would of been more than competitive with the ls3 chev. I've also heard that Ford US have already developed a 7.0 litre version of this engine and fitted DOHC heads, producing upto 800hp in their drag race testing programe aspirated..

I've only tried two oils in the T, but as many have said before I think the weights are the crucial part. I've used 10-40 castrol magnatec and 15-60 Penrite HPR, the castrol oil didn't last as well (after 15k it had lost it's colour and gotten pretty dark) but it was great at start up and seemed to let the engine perform more freely. The HPR 15 after 12k still hasn't lost it's colour, but I think it is decreasing engine performance, and to be honest it's probably an overkill (however I have nothing to back that up). My car's running 15psi and 320rwkw btw. Personally I think a 10 or 15w 40 is the best for the engine overall (performance and longevity, exactly what ford recommend) magnatec is ideal if you change your oil regularly and do short frequent trips. I'm going to try some Sin15 next as I'm impressed with the quality of penrite oil, just think I chose the wrong product last time.
