wow i searched other forums for this topic and everything said here is on there. I guess I'll just wait to see what happens from here and keep my eye out for either engine.

thanks

 

I'm sure you could fit it but may have to get custom engine mounts, tranny, electronics, etc.

 

Most likely it's just a bore/stroke change to get from the VQ35 to the VQ40. If htis is the case, then you don't have to worry about new engine mounts.

However, there are some problems I see. You are going have to mod your ECU to account for what is probably a longer stroke and the VQ may not like the longer stroke at the higher rpms. Just a lot of problems.

You sound like you'd be ready to spend some $$$$ to drop a VQ40 crate motor. For the same money you can go with a supercharger and get much better performance gains on your current engine.

 

I'm just looking at different ideas for a project. If the vq40 is a direct fit then I want to see what I can do to fix it up with internals and turbo.

 

Since it is just a bore/stroke change as GZire mentioned, it will probrably fit with some mount changes.

 

By the time you figure out how to do it and all the costs associated with a custom fit, you could have just bought this

A TT or supercharge @ 9 PSI on the 8.5:1 version of this with the right heads and cams would probably get close to 500 crank HP. You would be into it for $17-20K, but it would be sick, sick I say.

 

that 4.3 kit is nice, but at the price I think i'll just stick with the stock engine and build up the internals for turbo.

I did find a lot on this same topic on other fourms. I guess it's vq40 is the same engine bored out. When I actually saw it in a 05 pathfinder the whole top was configured differently. The whole intake tubing is in the front of the engine instead of starting in the back like the G and Z. The test drive was fun, all the pathfinder needs is a manual model again. The auto is still very responsive.

 

I remeber someone asking the same question but it was sorta shot down because the engine is not really desinged for sport car performance but more for rugged sport towing power.

 

I was under the impression that it was the same bore, just stroked.

 

Jun 3.8 or AEBS 4.3 storker will yeild you better results
