you have it sorted I would say just gotta put it together, would suggest twin lines and lockoffs on each converter, just to be safe.
It will do better than 12's I'll put money on that!!!! What inlet manifold? XF EFI would work pretty well if it fits on that engine. |

Sounds great. Is it EB pistons in a 250 motor or a 4lt?
If it doesnt do a 12 theres something wrong... shoould easilly pull 300wkws all day. Post up some pics if youve got any |

hey mate just out of curiosity... how hard was it to fit the 4L in???
sounds like it will be a lot quicker than 12 sec!!! theres something on here about an eb runing 12's with 250rwkw maybe a bit more??? yours should be in the 11's easily!!! good luck with it all cheers |

i have not fitted the engine in yet,i was told to use the standard xe/f mounts not xg and should be good fitment.if i get a 12 goodie,but we will see wot happens when the methanol injection gets fitted.

jumping up to a 510 instead of what you have might benefit, only costs 100$ to change the diffuser, thats what the red one runs.
Are you going to run H20/meth or just meth? I don't think you will need it, just fill up with straight propane and you'll be more than happy. |

i was thinking just meth only.i might go to gas research (there only around the corner from work)and find out about getting the 480 converted to a 510 like u said.any thoughts about the injection would be great as its my first time using it(if its worth it).the car will be a weekend cruiser and the strip once a month,part show.

I've heard its not an easy job to put the 4lt into the XF bay... isnt it too long or something?

nah,one of my tech that work for me is in relation to the red xe that runs tens,said it basically sat straight in with standard xf mounts not xg.ive spoken with another chappy that has fitted a 4ltr in an xe and had no probs..there is one other that fitted a standard ef 4ltr in an xd and bolted up ok.

I have a ef 4 litre in my xf. I found that the motor bolts up to the mounts ok but it sits the motor lower in the engine bay. I found that when the weight was off the wheels the standard xf swaybar touches the sump so i put in the xg lower mounts with e series upper mounts (EA to ED).
I also put an xg swaybar in to help clear the sump. You might get away with the xf mounts and swaybar but i just wanted to make sure the the job was done once and done right for my own piece of mind. I was fairly sure that when the weight was on the wheels the swaybar cleared the sump. Since all of these changes i have also had to swap the broardband intake manifold for an e series multi point manifold from EA to ED to clear the bonnet as now the motor sits higher. Oh and lots of other stuffing around which i wont bore you with right now. If i can help you out any along the way feel free to ask questions. |
