5.4l xf project

I am looking at putting a BA 5.4l motor and gearbox into an xf falcon. I am after advice on any potential problems that I may come across besides the RTA. I have heard that the sump may need to be modified? Will the motor and gearbox fit in without any mod's to the engine bay; do the engine mounts need to be extended? Any hints/tips help.

Re: 5.4l xf project

first thing id be thinkin is what your gunna do for a bonnet? i doubt the engine would fit with the standard bonnet. id dare say youd need custom engine mounts as well as changing the diff and drive shaft.

Re: 5.4l xf project

Are you loaded with $$$$ mate?

If you were going along the lines of new powerplant into XF why not a BA twin cam turbo?

Wonder if the V8 would even fit between the shock towers with extractors on? One of those notching kits would be a must i assume----> http://www.rrs-online.com/html/products.htm

Re: 5.4l xf project

That would be an awesome car! Best bet would be to find a written off V8 BA... And talk to an engineer. Anything is possible, but it might cost a bit!

Re: 5.4l xf project

www.suburbanimports.com.au they had a 4.6 ltr quad cammer for $8900. hope youv'e got deep pockets. Remember these engines have been around for a while in North America now. Older ones should have a conventional throttle cable and an aftermarket ecu is easy enough to install. Clearances ( and approval ) will be your biggest drama.

The XF is gone Injected 351W looking for a new home.......

Re: 5.4l xf project

I've seen an AU with 4.6 modular motor in it at one of the car shows (auto saloon I think). It envolves choping the shocker towers and all that sort of stuff. Unless you can do the work yourself or you are loaded with money forget about it.
