turbo rebuild question

[JFatch1890]

i have a small 16g, and a friend has a big 16g turbo rebuild kits............. are they the same? do i have to have it rebalanced????????

 

[JusMX141]

-Yes, they are the same kit.

-No. Read this for more info on balancing: Turbo Balancing

thank for the info guys

get it balanced.

 

[JFatch1890]

any one with the correct knowledge of balancing, one says yes, and another saysit dosent need to be

Did you read the link I posted? G-Pop isn't some fly-by-night organization.

If you need more convincing, let your mouse idle on the red dot at the bottom of CorrupTTalon's info for a second or two.

yea, i did see that as i read his post, and i figured i dont see that much so i knew i should ask to be sure thank you

Mitsu wheels come balanced before you get them man (your turbine side is balanced and your compressor wheel is balanced - separately rather than as a unit) . Toss it in - this doesnt mean that sending it to get balanced is a bad idea.

hilarious. and if you actually checked, youd notice i got a bad point for cross posting FOUR years ago. .

i dont live on this forum, jusmx141 and i dont have one negative point against me for advice on this forum. so suck a fat one.

JFatch1890, ive been good friends with a guy who builds custom turbos for a living for many years. learned many things. and hed tell you to get it balanced.

have you ever balanced? atleast seen someone balance a shaft? have you actually seen a turbine spinning at high RPMS? if you had the slightest clue as to what that turbo is doing then youd treat the internals with care and get the thing balanced. it will save you in the long run.

 

[JFatch1890]

point taken. i just dont want to wait to have balanced if i dont HAVE to

What is recommended by VFAQ is to mark a lines for where each wheel with the middle piece of the turbo. This will be so you put it back together as close to balance as it was. Hopefully exactly as it was. The kit is in the shed . If its bad weather be careful. Im hoping to get out of school tomorrow. If theres snow. I hope I have time to practice some drifting in the parking lot.

The hand out warnings a lot I think they will understand. Once they leave ill start again. There are some cops near me though.

If someone builds custom turbos, that probably means they are assembling compressor wheels and turbine shafts that weren't intended to be put together from the factory. This would prompt a balance check.

Anytime I've bought a new TD05H turbine or 16G compressor wheel, it comes balanced when you buy it. I've even asked my turbo parts supplier if balancing a MHI turbo is necessary when you swap a damaged wheel for a new one, and they informed me that because Mitsu turbos are assembled from parts that are component-balanced, they do not require any special type of alignment for reassembly because all of the parts are balanced individually. This means you do not need to mark the shaft and wheel for turbos that are component-balanced.

It's interesting to me that a shop like G-Pop will openly tell you that your turbo doesn't need rebalanced. I honestly feel these shops are such balance whores because they need to pay for that fancy $20,000 balancing machine.

Now I'm not saying to never balance a single turbo or individual part....I've already bought Garrett wheels that didn't come with a single balance grind and absolutely needed to be balanced before assembly. You just have to know a situation that would prompt a rebalance:

- If you're rebuilding your turbo and you notice that excessive in/out shaft play has caused the wheels to kiss the housings, but neither wheel has sustained major damage that would prompt replacement, the turbo should be rebalanced.

- If your compressor wheel has a couple nicks and chips on the leading edge of the fins at the time of a rebuild, you should have the wheel rebalanced.

- If you're doing a routine rebuild and you're not replacing any of the wheels, you do not need to have the parts rebalanced.

- If you're replacing one of the wheels on a component-balanced turbo, you do not need to have the turbo rebalanced.

If the turbo is component-balanced, the compressor nut will not have balance grinds. Anytime the rotating assembly is balanced, the turbine shaft, compressor wheel, compressor nut, compressor seal collar, and thrust bearing collar are all spun.

CorrupTTalon, I didn't mean to insult your intelligence....I just feel there's a big difference in the advice given by someone who happens to be friends with a guy who builds custom turbos (yourself), or someone who has rebuilt over 200 turbos out of his garage in the past 5 years without a single labor-related failure (me). I hope you understand.
