Limits To Xr6 Turbo Q&a

[Grimketil]

Hi team,

Did a bit of a search to find a comprehensive list of the limits to the different parts on the B series XR6T's, nothing came up. There is a sticky on the FG's but they are a different beast. I guess all the info is here on this site individually, but a nice list would be handy.

If we could group source the info and sticky it, might help newbies like myself. Been a Fordmods member for a long time, but they don't seem to have as much knowledge in their userbase on the factory turbo sixes as on here.

If we could list the parts, and fill in the blanks about what is reliably accepted from the following components:

Factory Injectors: I've been told 10psi will push them to their safest limit.
Factory Fuel pump: good for ??? rwkw, anything more requires upgrade.
Factory dump pipe: good for ??? rwkw, anything more requires upgrade.
Factory Cat: good for ??? rwkw, anything more requires upgrade.

Factory exhaust: good for ??? rwkw, anything more requires upgrade.

Factory wastegate actuator: good for ??? psi, anything more requires upgrade.
Factory Wastegate flapper: good for ??? psi, anything more requires upgrade.
Factory intercooler: good for ??? rwkw, anything more requires upgrade.
Factory piping: good for ??? psi, anything more requires upgrade.
Factory valve springs: good for ??? rwkw, anything more requires upgrade.
Factory Throttle Body: good for ??? rwkw, anything more requires upgrade.
Factory Tubocharger: good for ??? rwkw, anything more requires upgrade.

etc etc. That way those newer to the ways of the XR6T can look up what parts are likely to restrict first, and plan an upgrade path, rather than just go about slapping bits on, without the right supporting mods.

Thanks in advance for the help.

B series turbo good for 400rwkw with flapper upgrade.

Throttle body good for decent power.

Everything else, not much room mod wise on a B series. maybe 50rwkw

BA Valve springs will max at 9/10psi

BF have stiffer springs

fuel pump will top out around 260-270kw

Wastegate actuator should see around 300kw
