Borg Warner s256 VS. Precision 50 trim journal bearing............ Thoughts, comparisons, test info, flow characteristics, ANYTHING AND EVERYTHING!

 

I thought you allready purchased the BW, if it were my choice I would go with the 256 over the 50 trim all day long .

 

HAHAHA.. Yes i did.. Lol comparing to my friends turbo.. he thinks his is better!!

 

the thing with the 50 trim is they all vary from one manufacturer to another like say a 50 trim from turbonetics will have a different power curve and compressor map compared to a garrett 50 trim and there are many different exhaust wheels and housings to choose from that will change the overall performance of the 50 trim as well. But none the less I would still choose a BW s256 over a 50 trim.

 

get a forced turbo

 

Well thanks there dsmjeff but as u might not be able to read.. Ill explain.. I just bought a Borg and was comparing to my friends turbo.... Not asking what turbo i should get!!! Thanks

 

What size turbo does your friend have?
Exactly the size, part number anything?

 

Ehhhh not to sure hes kinda sectrative about it.. lol as am i with my friends but i know for a fact its Precision 50 trim journal bearing... not sure what turbine or any of that..

 

last I knew all the precision 50 trims were 54mm inducer 76mm exducer and offered as a .48 or .63 ar exhaust and rated at a max of about 450 hp I would lead to bet you would make a lil more HP at same boost but I am sure you will carry torque earlier and longer then his.

 

Wow only rated to 450.. Bw is rated to 550 sounds good...

Anyone else??

 

Absolutely not.
And just because they rate the turbo for XX does not mean that is the case. I have seen some well beyond their "limits" The BW may have enough flow potential but it doesn't make it a better turbo. There are many factors involved.

 

thats why I said before it depends on who makes the 50 trim and what wheels and housings were used in the turbo, I have seen 50 trims make more then the rated power and I have also seen an s256 on Trick Engineering's dyno put down 621 hp on a built integra GSR it all depends on the combo of parts, tune and how hard you want to push it as well

 

The best way for you to tell which setup works best between you and your friend is to have them tuned and dynoed. Same dyno, same day.

BTW: I hope you plan on posting your results, cause I'd like to see them, too.

 

Well he doesnt have and evo but we put down the same power before we both upgraded turbos.. thats the thing.. doesnt matter that im 4WD... HES FWD

 

That must be a painful experience for him.
