George I believe these will be similar to the XRD DB Engines GT 5port I am currently running as they come off the same production line.
If they are, then it should be a great motor.

I have been very happy with the performance (low end especially) of the XRD FT Line

Thank you very much for the reply!!
How about runtime and top speed? What pipe do you use?
How was break in? I have an ebis for initial break in of my engines!

George, run time is around the seven and a half minute mark.
I am running the FT line pipe and GT header. The pipe is EFRA2068.
I did try a Nova header (shorter) and a hipex pipe and it improved the top end but certainly took away from the bottom end.

My motor was ebis then run on a break in bench before being put in the car. all up i think it took close to 5ltrs of fuel before it finally broke in.
It took a while but was worth the wait.
