BB Turbo question

Aside from the quicker spooling, what are the benefits in terms of reliability of a BB turbo over it's stock counterpart. I want a BB, but I don't want to sacrifice reliability.

I currently have a GDS aftermarket turbo which has been said to be the same as the TN non-BB turbo. It has run well, but is beginning to leak a bit of oil through the exhaust.

I had heard a year or so ago that the GTP 38R had surge problems?? True or false?? Also how does the GTP-38R compare to the TN BB unit?

These are only questions meant to educate my buy decision. I am hoping not to incite a riot.

The Garrett BB is still the top choice of proven drop in turbos and the surge issue is more common on the Internet than in real life.
I'll stop now and not post again in this thread so as not to fuel the part in bold

I want a BB, but I don't want to sacrifice reliability.Quicker spooling was not part of the plan, it is a side benefit. The double ball bearing was used because it is more durable at higher boost levels you will get with this turbo.

Since my buddy is skeered to answer, I'll answer. Besides, I like riots.

If only those who knew what they were talking about replied, this thread would still be on page one.

Re: BB Turbo question

i have been very happy with my tn bb.i feel it out performs my stock turbo hands down.i can't speak for the gtp38r i have never ran one.from what i have read on the forum the gtp38r is a good turbo also.i think it would be your personal prefference and probably price.

I cant believe i am agreeing with u 444!!!! but u are right. to me they are both good turbos, but the Garrett has been out a lot longer and is more proven. some people have had surge issues, but it really isnt that many when u compare how many Garretts are out there.

Re: BB Turbo question

I haven't tried the TN BB but I am very happy with my 38R. I think it may be the best drop in hands down.

Re: BB Turbo question

Thanks for the opines. What about oil leaking into the exhaust. Is the bearing cartridge and shaft sealed the same as the standard Garrett with a C ring? That seems like a weak point at least in my experience.

Also, what boost pressure is common with stock injectors? Since this is my daily driver I want to get the turbo shaken out but was also thinking of going to Stage II single shots or Single shot AC's
