I'm thinking of a V8 swap. The local speed shop is keen to do a LS and I'm thinking it over.

 

Meanwhile I have a 91 Infiniti Q45 that runs great with 175,000 miles on it.

 

I'm wondering about the possibility of swapping the Q45 engine/trans into my 71 Z. Has anyone done this?

 

Any ideas  about doing this.

 

I will appreciate any and all feedback.

 

The car will not be raced but just a Sunday driver with a little extra balls.

 

Thanks.

Thanks for the info. These links led me to info about the engine.

 

Anybody have anything on the feasibility or difficulty in swapping the Q45 engine/trans in to my 71 Z?

 

I'm not very savvy  on the details but have access to a really good shop.

 

 

Any and all info appreciated.

 

Thanks.

Did you see the threads about swapping the engine?  In this sub-forum, the one you're posting in?  Thought the links would lead you there.  Not really clear what more you're asking.  Good luck.

Thanks for the feedback. The first links only took me to Wikipedia and info about the engine. I don't know why.

 

These new links told me what I wanted to know.

 

Basically it is not a easy swap. I thought I would save some money because I have a nice 91 Q45 that is not worth much money but the engine/trans are in good shape.

 

The fabricator wants $10,000.00 for a  ls swap total. I thought I would save the engine/trans costs but it looks like the swap details would eat up the savings.

 

In addition the shop (Bones fabrication) is very familiar with the LS engines having swapped them into many different bodies.

 

Anyway thanks for the help.

If you already have the Q45 engine (VH45) then it will be cheaper to swap than an LS1 would be. The amount of fabrication needed to get either engine swapped should be roughly the same.

     Like you, I have a Z, and I also acquired a great running 1991 Q45 VH45 engine, and would like to re-build the VH45 engine and install in the Z with a turbo attached.

I look forward to any details of your conversion which you care to share.

Would the swap be eaiser if you faced the headers forward and turbo'd the VH?  I have a vh45 and a 5.0/t5 sitting here and trying to decide which engine to use.  I love the idea of the VH and keeping it Nissan, but if its that much of a pain in the ass I'll buy the kit for 400 bucks and bolt my 5.0 in there.
