FJ40 mods

[faithy1234]

G'day,

I've got a '79 SWB FJ40 with a 2F. I'm planning on putting a 4L straight six and auto from an EF Falcon in and running GQ diffs, suspension (lifted) and transfer case. I've spoken to an engineer and he's happy to engineer it all after I have it welded up by a pro.

My main reason is that I want an auto and the Ford engine and auto are so common and easy to replace if needed. The engines go ok too with a cam (for bottom end and mid range, of course) and headers, and they're better on fuel than the 2F. I was going to go 80 series diffs but I've lined up some GQ diffs, control/radius arms and transfer case from a mate. I've heard the patrol transfer is tougher than my FJ40's transfer.

Can anyone see a problem with this? I know half of you would recommend a v8 or to stay with leaves but I have all this gear lined up and reckon it'd be alright. Any ideas?

Cheers,
Josh

i think if your going that far crazy not to go a V8.
and som fords go sweet. but ive seen one in a jeep with the dizzy down low at front. everytime he hit a puddle the thing would stall.

holdens have it up the back.

I think you'll find the firewall wil need a few mods with the injected six as well

maybe have a look (SEARCH) too in members and toyota. a few blokes have done just such an engine conversion be handy to contact and view buildups?
and others have gone GQ diffs, the prices have but im not sure if their build is on here.

I've done the EF I6 conversion to cruiser 5 speed. No big firewall mods, just a little "persuading" to clear the end of the inlet manifold. Good conversion. EF I6 is distributorless. They run a coil pack mounted low under the inlet manifold which can easily be relocated to the top of the rocker cover. Check the link in my sig for pics.

We only went GQ in the front of our 40. We used an 80 series rear.
With the coil conversion we used the GQ coil mount and welded it straight to the chassis with some bracing, and fitted a 5 link as that was what had been previously fitted when we bought it.
