I'm looking at upgrading to the V8 and I'm wondering what needs to be done. I'm running an XHII 6cyl dual fuel manual, its a tradesman (1 tonne) as well. I have my eye on an EF xr8 auto sedan (dual fuel). what would be my easiest option as in EF, EL, AU, etc.?

Cheers all.

I'm doing a similar build soon except I'm using an AU xR8 motor.
Do you have a whole front cut to use or just an EL motor?

whole front cut? I'm be looking at a whole xr8 sedan, still registered.

I'd want to keep my ute a manual though.

EF or EL are ideal for an XH V8 conversion. EL is the better option.

Why would you buy and wreck a perfectly good EL XR8 and put it in an XH 6cyl?
Just buy an XH XR8.
The only reason I'm doing mine is because the AU was from a mates wreck and very cheap and I also bought my XH cheap. Overall, the total will cost less than a nice EB SXR8.... or an XHXr8 for that matter.... and I'll have more power.

Manual from a 6 cyl won't fit without some coin
(dellows bell housing, input shaft extension, v8 flywheel, v8 clutch)

So you'd have to source a nice manual el xr8 (more expensive) to strip (please don't unless it's a wreck)
or source a manual box separately, which are pretty hard to find and I normally see sold for $1500+.
