Anyone ever dealt with the reman company on EBay that sells our engines remaned? Since I'm getting ready to acquire a 130k mile Z that I was originally going to do a LS swap on but voted against so I can buy me a house I was thinking light built NA VQ that I'm gonna make a track car out of and of course keep it forever.

Any reviews? There greatly priced at 1700$ with shipping and a core charge which of course I'm not worried about.

I briefly looked into engine options myself as mine is burning a bit of oil. I think they some with warranty of 1 year, no?

^^^ only if you have a certified mechanic do the install. If you do it yourself you get a 90 day unlimited mileage warranty.

Yea 1 year unlimited mile warranty and I'm goo on the certified mechanic putting it in lol

What is remanned though? Like if you get a rev-up and it has the same specs as prior, will it just burn oil down the road?

damn thats pretty good, i wonder if they would be cool with installing aftermarket parts provided by the customer in the build process. Such as Cams, springs, retainers, rods, better head gasket etc. etc.

find out name of company, look up in local bbb, google them etc. Find out who does their "reman" work.. themselves or another machine shop.

They do it all. I would post a link but its in a app on my phone

Sounds good to my untrained self.. Now only if I was smart enough to pull my motor out and drop this one in..

Stock for stock, what am I looking at price wise? Does anything need to be done with ECU if tuned with Uprev?

If you are trading a DE for a DE, then nothing should need to be changed via your ecu

You should be fine. You might need to do a TB relearn and possibly clear some codes after changing the motor. The Uprev will stay on the ecu.

Also, if you have the cipher cable, you can instantly clear any codes you may get.

good luck

Ok so back to any shops etc have experience with remaned engines?

As a Nissan ONLY motor builder, the term "reman" normally is something we get concerned with.

Most of the companies that remanufacture motors do things that traditionally don't fair well for Nissan motors, such as cutting the crank for thicker bearings, not paying attention to the tolerances in the heads that are required, and using gasket material that are "no-no's" in the Nissan world.

Now......not saying that place does, but most reman places focus heavily on domestic motors and carry the same (what they think) build quality to Nissans as well.

Possibly look into a quality USED motor.......you might be surprised at the prices. Again.......that place may be building it right, but check and see what other brand motors they build..........that should help you see their focus.

How does one know a good motor when purchasing online?

If I wanted a used motor I'd just stick with the one in the car. This threads kinda steering away from original post. I understand the thought behind a remaned engine. Or even a used turbo kit parts etc. just seeing if any shops/ members have any experience with them.

Talked to the company on the phone they seem to know their chit. They reman to factory specs not what they think it should be

My sister got a reman 4g63 from Jasper. Cert mechanic put the block in, hooked everything back up with new OEM hoses and everything seemed to work perfectly. That was until she got confident that the motor could handle the OEM turbo again and the rings pretty much blew themselves to pieces. I'd stay away from reman.

Hmmm interesting.

I work for an engine/transmission re-manufacturing company. Assuming the install goes correctly, there should be no issue with it. Who is the manufacturing company? Usually when it comes to the warranty on a reman engine, it all goes back to the installer. We dyno test every engine that leaves, assuring that there were no problems. Just make sure they do the same

(sorry for resurrecting an old thread, was looking up some vq35de information and this thread came up on Google)

Jasper is pretty big on their warranty (parts & labor for 3 yr/100k mi) and using the best parts for a given engine. They've actually been pretty slow getting into the import rebuilding scene and picking up a new engine codes one at a time to make sure they have a solid grip on a given SKU.

I find it more likely that your sister does not know how to identify boost creep, or compressor surge and that a wastegate / actuator problem was what killed the previous motor and then the new one than even the cheapest of Chinese knock off rings failing so early after install. Equally possible, it is more likely that your mechanic knew the Jasper warranty is one of few that covers labor and ignored bad turbo control parts to get the extra install hours a second time around, and while the bolts were still fresh and easy to pull.

Even with substandard parts all around, it's unlikely for the situation which you propose to be true without some other significant factor. There just aren't that many companies making rings and bearings for a given engine to run across any that would fail at OEM power output / stress so quickly. Faster than OEM by a factor of 4x quicker, sure, there are 1-2 companies, but not on the scale of weeks / months.

Something was missed or ignored on the installer side on the order of 10000:1 odds compared to a manufacturing line reassembly flaw with several people specialized on one or two parts and others checking prior work at each stage.

People like you and your sister are why more turbo cars don't make it to North America for sale. The consumer base sucks and is vindictively ignorant and blaming of the wrong parties.

It's like the people who buy a $600 Acer or Dell consumer line laptop (10% margin product) and lament how much Windows sucks after they visit a bunch of shady @$$ websites and how great their $700 iPad (40-60% margin) is and "just works". Business class laptops at $1200 (20-30% margin) "just work" too and don't get me started on enterprise aimed models (same specs, better parts, $1800 , 50% margin). Apple crap "just works" because it is a step below enterprise class hardware at better margins, thus more invested in QA.
