Hi there,
I was thinking of transplanting the EFI 250 crossflow from an XF into my Alloy-II 250 crossflow XD and just wanted to ask a few questions. Firstly, can the EFI engine be swapped straight over? What's the go with the computer? Does it stand alone or would I have to carry over a bunch of electrical gear from the XF? Secondly, the XF is an auto and I am running the stock 4spd manual in the XD. Would the flywheel and bottom-end from the auto engine be balanced differently or need rebalancing to mate up to the manual gearbox? Will swapping from an auto to manual gearbox muck around with any engine management gear from the XF or is the old stuff not that clever? Cheers for any advice anyone has.

you will need to put the engine bay wiring harness in for the efi, you will also need an efi fuel pump too i believe.
other than that, i think it should all work together relatively easy but then again, i have never done this sort of conversion - so i might be completely off

they are exactlty the same enigine you will need the wiring loom and the puter and fuel pump also. you can just bolt the head onto the xd block if your feeling lazy

To change the fuel pump you'll need the fuel tank as they are slightly different. Also, if you've got a donor car handy the fuel lines themselves wouldn't hurt either. Other than that everything as far as gearbox etc bolts straight up.

mate, first id ask what are you trying to achieve.
Personally i reckon you wouldnt be happy doing the conversion or with the end result. The injected version of your engine wasnt that crash hot. Depending on what you want to achieve id invest the money into a weber (if you arent running one), decent exhaust, and a five speed manual. This would give you power and economy and its tried and tested 100 times and easy to do. |

Yeah I sort of back up this answer, the intake etc is worth keeping and either fitting aftermarket ECU or straight LPG. To many parts on EFI XE Bosch and XF EECIV systems fail, just a leaking gasket can make it run rough and the vane airflow meters should have been put in the bin in the first place (I would be nearly rich if I had a dollar for everyone I have seen playing up from being worn out). Polish the tappet cover and intake, they look awesome polished, there was a EFI XF wagon that used to do the car show circuit in the 90's with that done, it was black with red wheels etc, it was perfect from top to bottom fitted with a T04(?), twin perfect polished 2 1/2" stainless exhaust. Show name was Redback I think. Singleton NSW TAFE fitted a XF EFI engine to a XD back in the early 90's, the engine for years was run on a display stand, so they didn't have a donor car, I had a quick look at it but I can't remember how they got around the fuel pump problem as a XE/XF tank won't fit and I remember it wasnt just sender/pump assembly replacement. (I also wondered why they bothered, as I was just about to heave hoy my EFI out of my XF, for a Cleveland transplant)

Thanks for the insights and tips guys,
I had guessed the old injection system wouldn't be that crash hot but from the sound of it I'd spend more time buggerising around with it than enjoying it. I was hoping for a quick, cheap or easy swap-mod to entertain me at the moment due to a study-induced lack of diposable cash income! I guess saving my pennies for a newer E-series and shelving the XD for a later date with a bent eight would be a better strategy. Back to the drawing board...! Cheers all.

Could always put an xf efi head on it for better flow also i think the 3.9 head fits higher compression

Oh for sure.. e-series are very cheap now. Esp if you don't mind high K's
And an ef/el would be a much better car in so many ways. |

There is a sweet looking EB XR8 on CarSales for 5K. If only I wasn't a poor student...!
