I would never consider paying somebody to do the work, but as a long term project sitting in a garage for a couple years while I do literally everything myself, hell yeah... It'll be a race car / night runner either way so IDGAF about insurance values.

 

There's a guy on YouTube that documented every single step of stuffing a LS motor into a 2004 Miata. He did ALL the work himself and in the last video (published several months after he finished it), he documented all the costs involved. It came to $43,600. Now mind you, he used a crate LS motor and that was 12-15K if I remember correctly, but even without labor costs. After selling all the parts he took off the Miata it was $38,800 and 9 months working on it when he could


Edit: Found it, here is the whole series:

 

How could it be that much. Dear god.

Some nut is trying to stick a hell cat engine into a 350z recently.

 

Keep in mind that's a $7 LS3, probably $5k into the transmission, custom frame, probably $3k in the rear axle. That's for GM OEM basic components, using an older generation LS motor can be significantly cheaper.

You can pick up an LS1 for under $1k, LS2/6 for $2-3k. Complete Sikky kit with everything else needed for $4k. If you rebuild the engines then toss on another $1500 or so, you'll definitely be running a different cam so figure in at least some money for that but if it was a low mile salvage vehicle donor then it might not even need a rebuild.

So it CAN be done for significantly less but probably not any cheaper than $6k or so unless you picked up some used components for ultra cheap.

Most of the high estimated costs for swaps are because folks are paying out the 80+ hours of labor to a shop to do the work.

 

You can get the 2002 q45 engine which I'm using for as low as $250 heres the link : http://www.car-part.com/cgi-bin/search.cgi?userSearch=int&userPID=1000&userLocatio n=All+States&userIMS=&userInterchange=E%3FBAB&user Side=&userDate=2002&userDate2=2002&dbModel=34.6.1. 1&userModel=Infiniti%20Q45&dbPart=300.1&userPart=E ngine&sessionID=11000000075242584&userPreference=p rice&userZip=07011&userLat=40.8800000&userLong=-74.1446000&userIntSelect=1155311&userUID=0&userBro ker=&iKey=&userPage=3

The engine wiring harness for like $175 link : http://www.car-part.com/cgi-bin/search.cgi?userSearch=exact&userPID=1000&userLocat ion=All+States&userIMS=&userInterchange=%5B%7C%7Br &userSide=&userDate=2006&userDate2=2008&dbModel=34 .11&userModel=Infiniti%20M45&dbPart=699.1&userPart =Electrical%20Part%20Misc%20and%20Wiring&sessionID =11000000075242897&userPreference=price&userZip=07 011&userLat=40.8800000&userLong=-74.1446000&userUID=0&userBroker=&userPage=1&iKey=

Then you will need the 40 pin connector from auto sport wiring harness.

The good thing is the engine fits using the stock vq mounts ( I think they might have to be inverted) without any modification.

I started a new thread to document the swap, link : https://g35driver.com/forums/g35-cou...wap-guide.html

 

I'm trying to find the guide to do this G35 Coupe engine to Q45 engine swap, how do we get all this info on doing it??

 

Just Pm me and I'll help you out. I started a thread just for the swap here's the link.

This is something I'm working on, the covid set things but hopefully I can have this done soon. I wasn't going to release any part of this until it was completely done but **** it, I learned a lot on this forum and this is where it all satrted any way.
