Which is beter?


Would rebuilding an old tired engine give me more power than a remanufactured engine?

its kinda the same thing....just remanufactured is done in a shop, and you can rebuild your own.

would depend on the specs


remanufactured is rebuilt is it not

use the old major componates and remanufacture them

if built the same then should be close to the same

just a matter if you wanna do the work or pay for the work bn done

ok.. if your looking for power and you want to do some head work and bore out the pistons stuff like that , then having the motor rebuilt would be the way to do it because someone can make those changes while rebuilding the block.. but that costs money and isn't cheap.. now the remanufactured engine depending on who you get it from is more or less the same thing but they remanufacture it to the factory specs, meaning it's going to be the same power as it did when the car was running with a factory motor , but they do give some type of warranty which is a good thing, check out jasper engines, a bit pricey but there solid motors.. it's simple there is more of a chance of internal engine failure from human error when rebuilding, and less when remanufacturing because allot is done with machines and to be honest i would go with the remanufactured motor , just because the company does it all day every day, verses someone manually rebuilding a motor from time to time... but the question is are you just looking to get your car running as it should or are you looking to juice up your car to make it faster.. i just hope there is a reason you have to replace the motor , and your just not trying to make it faster. also depending on what kind of car , you can always just swap a bigger motor in the car which will give you more power..

Matdav78 is on point. Go with a remanufactured engine. They generally have a decent warranty. I'm a technician for BMW and i have seen plenty of independent shops rebuild motors that dont last due to inexperienced people either doing the machining or assembly. If you go with a company that does this all day every day then your chances of having a motor that will last are much greater. What type of car is it? Depending on what it is you could get a lower mileage used engine that would be much cheaper and still come with a warranty.

Good advice!! I've used Jasper engines AND trannys. No failures or comebacks.

actually there is a difference depending on who does it.....
a reman. uses new parts.
a rebuilt....they will use your old push rods and etc. if they are still good.
if you are building it......step it up!!!!
otherwise buy a crate motor and be done with it.
it really depends on the project and its intended use!!!!

I'd say rebuild the old engine. Gives you the chance to beef up the bottom end to withstand more power. Thats the plan for my thunderbird when that time comes.

well, I'm a professional mechanic.
so
a properly rebuilt engine
IS
a remanufactured engine
(that of course, depending on who remanufactures
your engine. hoe's engine shop
or ETC. and Brother's piston hoppers, incorperated.

but really. you NEED the inside, and I DO mean
INSIDE- (like, U got any mechanic friends in your city?)
scoop, to your town's resources.
but...
I suppose.....
if you had a mechanic friend, welll,,,,this post
would be redundant and unnecesscary , Yes?

clue, from a everyday tech.......



rebuilt right is remanufactured
so

you MUST

MUST find the right engine shop !!!!!!!!!!!


shouldn't be hard. they'll have been in buisness
since at least the 70's.
sound I silly?
consider...
he's in his 60's,,,,,,say 65.....
started his shop in his prime say....35....

get it?
in '78
he was already 35 !!!!!!!!!!!!!!!!!
now
that guy will
carbs
and
fuel injection.

not like me. I'm only 42. I'm in the middle.
I know 'em both, but someone 20 years older than me
knows em big time. thay have to to be successful today.
see?

If you put both engines side by side on a dyno they would probably read about the same.I don't think it matters too much since the majority of a rebuilt engine has new parts anyways.
