    Default EFI 5 Litre and T5 into a WB Tonner

    Hi all,
    I've got a 1983 WB one Tonner with a 253 and a 4 speed that I have just done up and am about to put back on the road. Lately I have been thinking of putting a VN 5 Litre into it with a T5 gearbox but I know that using the standard commodore T5 will make me have to move the shifter hole back and change the tunnel which I really don't want to do because then my console won't be right. I'm just wondering what other options there are as I have heard that an ea ford t5 will work well or change the input shaft and rear gearbox housing to ford mustang components will also work. I'm a bit stuck and wouod really appreciate some advice from people that have been through the process before.
    Cheers.

    Much easier to get an auto EFI 5-litre, heaps easier in fact. But a T5 is do-able, just need to right T5.

    Yeah I've been told an auto would be easier but the ute is already a manual and I would love to stick with a manual. I've done some research and found that an ea-el ford falcon T5 gearbox will fit in perfectly except for the crossmember which is easy to work with.

    Are those Ford T5's a different pattern box though? If they are you are up for a CRS/Dellow bellhousing too. Is the WB an origonal V8? If it was a 6cyl it may have a 6cyl clutch pedal which from memory doesn't have enough cable travel for a T5's clutch, so you'll need a WN V8 pedal too. Converting it to auto is easy. Just remove the clutch pedal, bolt in a HX-Z rod type TH400 shifter, shifter harness plugs straight into the dash loom, and stick the auto console insert in. 4L60E box will all but fit with a TH350 crossmember, uses standard TH400 speedo cable and will most likely work with a HJ-HZ TH400 tonner tailshaft with an original tonner front yoke on it (measure first though).

    Put some research into this a while back mate, the ford t5 is the easiest and cheapest way to go in this sense but as the other guys have said about the clutch pedal you may have to look into it as well as the bell housing.
    Cruise control only works if you take your foot off the accelerator.

    Hey guys, cheers for all the replies. I've done some research and I think the easiest option would be to use a ford T5 gearbox mounted to the efi 5 litre and buy a bellhousing from castlemain rod shop. My ute was already a V8 manual so the engine swap over wont be to hard, it will just be tryng to get the gearbox to fit.

    the box from behind the 6 cylinder will work fine and from what i read these are usually better than the V8 boxes anyway. make sure to put up a build thread!

    In my WB I have a Ford 6cyl T5 using a CRS bellhousing, WB V8 clutch pedal, the bellhousing uses the same release fork, pivot ball and clutch cover as the Aussie 4 speed. Not sure what the release bearing is and the friction plate is a Ford item to suit the gearbox.

    This will work with and turbo or Aussie pattern block as the bell housing come multi drilled.

    If you are going with an EFI you will also need a speedo converter, I used this to feed the ECU the vehicle speed and then a turbo to WB speedo cable.

    Yeah right, thanks for that. I've got some mates who can help me with the speedo and all that it was just the gearbox that I was wondering about. Hey MuckUte, going off of your WB did the crossmember have to be changed much and can you remember how much the CRS bellhusing was. If you could find these out it would be greatly appreciated. Thanks.

    This is the bill from when I got my stuff, it was maybe 1.5-2 years ago and shipping was to metro Adelaide.

    For the crossmember I started with one for a trimatic and modified it by welding a plate to the bottom and cutting a section out of the top for the mount to fit through.

    Cheers for that mate, umm would you just be able to tell me the price of the bellhousing because photo bucket isn't working on my computer??
    Thanks

    By the time you buy everything to mount the box to the engine you'll not get much change from $1500. Plus the box, plus crossmember mods. Plus tailshaft mods. You can see why most people just use the auto!

    Yeah but I'd like to keep the manual because the ute is already a manual and I might as well get the ute to how I want it to be.
