From my math the "6062" is a 58trim on the compressor but what i dont understand is the TX-66 (last one) seems to have the bigger compressor wheel but is a smaller trim? sorry for the noob question...


dont flame for the eBay turbos.

 

Then don't throw them up here for comparison. (I'm sorry to be an *** about this, but) just because you see half-assed measurements that they give you, doesn't mean it can help speculate what the airflow rate of the turbo is. You gotta take that plunge down that rabbit-hole for yourself. I'll simply say this.

Look to what each of the measurements mean, (if they are even stating them accurately) and make that decision.Typically, the larger turbocharger makes more airflow. Compressor wheel deals with behaviour, turbine wheel deals with top end power capability.

If you need diagrams as to the components of each, let me know, I'll post them up. But you must make that final decision.

 

should I find the trim of each turbo to determine which is the larger because the turbo with the biggest compressor wheel has the smallest trim and I thought the bigger the compressor wheel the more power it can make.

 

ebay turbos are natoriuos for lying about the specs, or the guy in china that made it really doesent know how to measure the wheel take you pick. Theres some tear downs on youtube that prove this. I.E they seem to think a 56mm wheel size is a 56 trim.

expect it to be smaller then what they say it is other then that its hit and miss like shodan said different results from different sellers.

Going of the info provided the first two should be about the same as the exhaust wheel and turbine housing are listed as the same specs

 

There's a guy with a couple holset hx40s for sale on the classifieds for forced induction. They're capable of about 650-700 wheel, and cost only a couple hundred bucks (ones a brand new rebuild)

In general, these turbos are cheap, plentiful in supply (hence cheap), very high performing and last hundreds of thousands of miles on the Oem trucks they commonly come from.

Tldr; for a slightly higher price, you can have a cheap turbo that will not only outperform on the dyno, but will also likely last a couple dozen times longer than any China charger


Your choice though of course

 

i have looked at those but I was worried about the whole divided housing because I don't have one.

 

No. The information is right there. Trim is just a distance between the inducer and exducer, to help determine air variance,(not translatable into a power number). It has nothing to do with the sizing.

 

You can run it with a regular manifold, it won't cause any problem. That or, either
A) find another holset, they're very common and I'm fairly certain there are larger sized ones without divided housings
or
B) Just buy enough another housing, pretty sure they're all over ebay :p
