3.0 Thorley headers on a 3.3??

Just came across this on Pirate...Anyone wanna try it on an X or Fronty?? Anyone see any problems with it?
Thorley 3.0 headers on a 3.3....

Very interesting. I may just have to look into it!

4x4parts.com has the headers,
and they are quite cheap if you dont go with the triple nickle or ceramic coating.
To the tune of $215.
Might be worth giving it a shot at that price.
And they have for pathy's with autos and manuals.

Anyone have a photo of the pathy engine compartment to compare it to an Xterra one?

Anything in the way?

something tells me the stud configuration is different between the two engines. Also, does the Pathfinder have the two precats?

You'd be removing the pre-cats either way and using the secondary cats, like the SLR headers.
And relocating the O2 sensors to prevent the engine light.

The bolt pattern would really screw things up.
Unless you get someone to cut a new flange.

::Goes to the dealership and asks for exhaust manifold gaskets for the 3.0L and the 3.3L engines with no intention of actually buying them::

The only difference as I recall is that the studs are bigger on the 3.3 vs the 3.0 as the block is the same between the 3.0 and the 3.3.

Oh, don't know if it's been tried or not yet, but if it doesn't work a guy with an R50 up in Fort Collins and I are trying to get another header option going.

Awesome idea!
If it's just the studs that are bigger, it shouldnt be difficult to open up the holes on the headers a bit to accomodate.

If the ports dont line up, that's another story.

That would mean that the ports match (or they are close enough), the only issue would be them not fitting the frame, or hitting the firewall, starter, or any other crap that might be in the way.

Well for those of us with BL's or those of us who plan to install one, clearance wont be an issue. I'm willing to try this route soon as I have started hearing the tell tale souns of a leaking exhaust manifold over the past week .

But I'm not sad, breaking shit means I can replace it with what I really want and hopefully gain some more ummph!!
