I'd like to start using amsoil but it's too expensive. $60 for 5 quarts and can only be purchased at authorized dealers.

My Mobil 1 EP is $26 for 5 quart jug and can be purchased at walmart.

Is $12/quart about what you are paying? If so that's 2x the price of Mobil 1 lol

 

Nice! Are you going to overbore it slightly to make the VQ37HR? You should start a build thread so we can follow along.


Mobil 1 is a pretty decent oil, I just prefer Amsoil. I'm a dealer so I don't pay $12/quart. You can also order it online.

 

No, I'll be using a VQ37VHR bottom end with my 35 heads. Bottom end in my motor is going to need to be rebuilt and I can get a low mileage 37 bottom end for around $1200.

I started the tear down today...

 

^^ Nice! Definitely keep us posted on what you find. I'm sure we can all learn something from the process.

 

Yep, for sure keep this thread updated. or start a new rebuild thread.
Good Luck!

 

Thought a rebuild thread was a good idea...

Here's the link

Was going to suggest a new thread as well! Great minds!

 

I also use Mobil 1 Synthetic with great results at 12 to 14,000 miles per BlackStone Lab analysis. But I also use a premium filter. If you want to get the extended oil change intervals w/ Synthethic Oil, don't use a cheap filter that isn't intended for that type of mileage. Mobil 1 filters also work great. But they are also more expensive at about $12 per filter. But again, you get twice the life of a regular oil change that cost $5 per filter.

 

To be fair, that AMSOIL graph is at least 7 years old from 2008. And AMSOIL-centric sites have posted it. Seems like something they themselves put together. It is a great oil, yes. But 7 years is a long time ago.

 

New motor in, back to normal.

 

Nice work! I wonder what the stealership would have charged for that?

 

I called a few performance shops in hopes I would get a faster car out of the deal.

The best quote I got was for a hybrid VQ37HR motor build. They were going to use a 37 bottom end and use my heads and intake manifold. I will go this route with the old motor and reuse the heads.

The quote they gave me was $4600 assuming everything was good. That wasn't including a new CSC which i know it needs per the factory service manual, anytime the transmission is disassembled. I knew this was more than I wanted to pay.

I bought the replacement motor from a wrecked 2007 350z on eBay with 47,000 miles. My car has 78,000 on the body so at least I was getting a fresher motor.

After all supplies and tools needed along the way, I ended up saving about $2,000.

Took me a month of weekends but it's back to normal...mostly. I still need to go down and have the AC vacuumed down and charged. I was quoted $85, I just need to find the time to get down there.

 

35Sport, Did you have to remove any spot welds on the core support or was it completely bolt on?

 

The core support is 100% bolt on. The factory service manual that is stickied on the main page of the sedan forum helps a lot!

I did have to disconnect the 2 AC lines that run from the condenser through the core support however. This involves having to reclaim the refrigerant first before it can be fully disassembled.
