b16a turbo size
up until just recently i was running at 450whp and 412 torque using a precision 5431E MFS entry level turbo, the turbine housing was A/R 63, at 1.2 bar's but my turbo did'nt last long, about a year to be exact, so i'm wondering if its the size, the fact that its an entry level turbo, the boost level or a combination of these things that ended my turbo's life.
this is my setup

Re: b16a turbo size
Unfortunately there are many stories and reports around Precision's durability and failures, so it may just be that your unit is one of those that live a short life.
As 2kdrift says, Borg Warner and Garrett have much better track records with reliability.
At 450whp and 1.2 bar you were using the turbo in its efficiency zone so don't see that as being the problem
PS: You referred to bar - which country are you in ?

Re: b16a turbo size
Those are solid options
You can also look at a Holset HY35 or HX35 with BEP T3 housing https://www.extremepsi.com/store/pro...roductid=23483
The Borg Warner S256 SXE also looks like a nice unit but the T3 housing tacks on a chunk to the base price !

Re: b16a turbo size
i did have a pic of the results on my old phone but i'd have to sift through my pic's folder on my pc and that might take awhile as nothing is sorted, been meaning to do that for a few years now, if i can get in to town this week i'll ask the tuner to print it out for me if he still has it.

Re: b16a turbo size
there is a guy other here that does this for holset's, that i've heard of, but not sure how good the end result would be. i once had it done to save money by using a used garret and a rb20 housing to save money on a new manifold with a ok results but power wise not so ok, as it maxed out at 340 whp

Re: b16a turbo size
Well I've decided to get the precision rebuilt for now until i can find a better option, I've looked in to the BEP housings and figure i can wait until it gets here and hopefully the rebuild will hold

Re: b16a turbo size
Take off the compressor cover and look on the face of the backplate to see if there is an etching there. (May be on the back also). There may be a date stamp on it. If it's before 1/07, is a Garrett. If that's the case, and it top a Garrett dealer for rebuild and not Precision.
Good luck
