VQ37 VHR NA rebuild suggestions.

Just dump that old motor and get a low mileage junk yard engine. It will be cheaper.

I wish it wasn't the case but she ran crap oil in it for too long and ran it dry before I came along and figured out the oil consumption issue.

Got the following quote from a reputable shop:

The cost for the labor and services of our VQ engine builds is about $5,800, which does NOT include any parts. Here's the breakdown of what is included in the $5,800:
Engine tear down and assembly = $3,500
Engine removal and installation = $1,500
Block machining (w/ torque plate) = $550
Rotating assembly balancing = $250

WPC treatment of the entire engine is $2,300. Includes the block, crank, pistons, piston pins, piston rings, rods, cams, valve springs and oil pump gear. So you can add up the parts you'd like to use in your engine (OE or aftermarket) and come up with a pretty close estimate.

I think that quote is very high, and cost prohibitive for us at the moment. That bottom line looks around $8k plus

Id listen to spooler and just pick up a low mileage motor from some place and do a swap at your buddies garage. Screw putting that much money into it for a basic dd street car.

That is cheap. That is not even going through the heads. Like I said, junk yard motor is your best option.

yup and dont be afraid of the awd engines, newer q50 awd engines are readily available this time year, lol snow, and all you have to do is swap the mount brakets, the oil pan. you can keep the new oil cooler and updated cooling system from the q if you grab a 2012+ z expansion tank and caps and then it won't suck *** to bleed the system and will be much less likely to overheat and lose the head gaskets. if you want to go with an aftermarket oil cooler you can take off the one on the q50 engine and loop the lines to it and swap the piece the filter screws onto from the one on your old motor. the newer engines have all kinds of updates to common problems. then if its a manual car definitly get a cmak kit for the clutch. this will all run you $2-3k

Forgot to mention if you get one with the wrong transmission all you have to do is swap in the appropriate pilot bushing for whatever trans you have

edit also you have to use your original harness and now is a great time to check it over for cracking tape, broken connectors, and corroded grounds

scored a lower mileage (56k) VQ37 from a 2011 G37.

Cool that shouldn't take any work to drop in, might have to swap the harness but it should be the same double check that it has the correct pilot bushing for your transmission ( manual or auto) and slap it in. I'm looking at a 2015 q50 awd engine for my car
