I agree Link to comment Share on other sites More sharing options...
Guest XR09 Guests Posted 27/04/12 08:08 PM Share Posted 27/04/12 08:08 PM Fg XRT and F6 motors are almost identical.FG F6 uses Mahl pistons and that's it.Top ends are identical from the XT to the F6.The XrT uses a different gasket to alter comp.The F6 uses a different gasket and bigger Turbo. (Or the same size as the XRT BF)Definately fit a new Oil pump. And feed to the journals if you can. Link to comment Share on other sites More sharing options...

But thought comp is altered by the concave depth in the piston. Edited 27/04/12 09:48 PM by Paulie2256 Link to comment Share on other sites More sharing options...
Guest XR09 Guests Posted 27/04/12 09:51 PM Share Posted 27/04/12 09:51 PM F6 and XRT run dif comps. So yes they do...the pistons. Also increases combustion efficiency Link to comment Share on other sites More sharing options...

Guest XR09 Guests Posted 27/04/12 10:45 PM Share Posted 27/04/12 10:45 PM Ha yes.Pistons add power and strength. But the rest is structure. Link to comment Share on other sites More sharing options...
