Whats a relative replacement for a pte63 but in BB form? ---

[alwayscode390]

I am trying to figure out if I want to replace my pte63 turbo for a ball bearing turbo. I will be using a 3k stall, atr headers and DP, ported heads, and a cam larger than a 422. I want it to make about the same power but spool quicker ( because of its bearing use ). Solid 11's is the goal. Thanks ---

a dual ballbearing will spool a lot easier than a standard thrust bearing turbo. you can go larger, but you should find the compressor map of the stocker and then look at the maps of the kind you would want. off the top of my head i would say a GT35R would be a good replacement considering the displacement and the flow and everything. i don't know the size of the exhaust housing on our stock turbo. i would guess its a .63, if its smaller, a .63 would be the next step up. i'm going off my reasoning for my other turbo vehicles.
i've only dealt with 2.2L turbo vehicles with T3 and T2 garrett turbos. all were a .48 exhuast housing and what i have upgraded to is a .63 housing as it flows a lot more air than a smaller housing. the compressor maps can be viewed on Garrett's website and would help you choose a good replacement that spools with about the same speed but will support a higher boost pressure. the size of the wheel in the compressor side is also something to consider. if you want advice, www.turbosunleashed.com call and talk to Chris, tell him the application, he can point you in the right direction as he is a dealer for Turbos Unleashed, Garrett and others

The GN version I have is a .63, but the SYTY version is .83 a/r. That is my other option, selling my GN one and getting a new SYTY one...but I am not sure if its worth it. I can rebuild my GN one for $300 , OR sell it and upgrade to a SYTY one for about $550 (after the sale).

Another question I have is , I have the BIG SHAFT version with no play and 20k miles of use after a previous rebuild. Is the BIG SHAFT more durable? Should I worry about rebuilding it yet (there are no signs of leaks but I havent ran it to see if it smokes). I would just hate to have problems skimping on a $300 part out of a $10k engine build, hehe. THANKS ---

you could get a 60 to 1 precision turbo or garrett 60 to 1 or soemthing comparable with a the same size exhaust size. stock size sounds like whats on my turbo diesel pickup, a GT35R is good over 30 psi an they are on lots of cars 4-8 cyls. i really don't what model DDB you will find but they are out there. Garret has all they sizes listed, look up what you want size wise comparable and in dual ball bearing.

From reading the threads you make about all of this, just keep the turbo you currently have, get your build, get a good tune and then see what you do with that. If you hit high 11's with that turbo and your build, depending on the psi your at you might be able to step it up a little more and hit mid or even low 11's with what you have.

Then, in the future you can sell your turbo to someone, put that money towards a larger one and not worry about it.

A GT35R (also similiar in size to a PTE61) is smaller than a SyTy PTE-63E. Next size up ball bearing is a PTE67 (and asorted exhaust housings).

i learn something new everyday. i guess they put a pretty decent size turbo on these trucks, from looking at it i'd never know, and i have one. hmm guess i might have to grainger valve it and alki mine and see what i can pull out of it safely

Thank you VERY much. Actually the PTE67bb is the one I had in mind. The problem I am having is the SYTY pte63 thrust bearing version is $995 , and the pte67bb is only $1250 ... personally I dont think $300 more for an upgraded turbo is much more.


The pte63 is rated at 650hp , and the pte67bb is 750hp. They will spool up the same right? ---

Great advice. I guess my worry is to pay someone to bolt all this up....then have a smoking turbo I need to replace ASAP. Atleast it wont damage the engine if that DOES happen....it will just be embarrassing and I will have to pay to get it taken off and a new one reinstalled ---

Pay someone to change a turbo...
Come on Nate, its not that hard to change a turbo.

I am always so embarrased to say stuff like that....but living in an apartment SUCKS. I have been warned a couple times for changing my OIL ... they dont like the hood up or the car jacked up. I know I know....time for a house. All my friends tell me that ---

Re: Whats a relative replacement for a pte63 but in BB form? ---

that 300 for DBB means you dont cook a turbo should you ever run out of oil or the oil pump fails or something similar. its worth the extra 300 that turbo you wont replace again unless you shove something in it

And my gf wonders why I tell her I dont want to move into an appartment.. :roll:

If the turbo in question, is actually in question. Then have it rebuilt. A 63 should put you into the 11's with a build. My 61 almost put me there on the stock motor..

Re: Whats a relative replacement for a pte63 but in BB form? ---

a 61 is capable of 11's easily as is a 63. the 61 uses the gt35 compressor wheel and is one of the most efficient wheels of that size. GN guys have gone 10's with the pt61

67 DBB would be awesome though

The stock turbo isnt a 61, its a mitsubishi TD06-17C / 8cm2. They measure differently then garrett does, I'm not sure how they compare ar sizes, but the ones talked about above are larger.

They would be rebuilding it to stock specs....not DBB , is that possible to rebuilt a thrust bearing turbo to DBB?! ---

 

[Xtrempickup]

Re: Whats a relative replacement for a pte63 but in BB form? ---

i dont think they can make a thrust into a bb. any DBB turbo will outlast a thrust bearing turbo and cost about 300-500 more than the same size turbo and it would spool faster

it would require a new center section i believe

Nate, my garage isn't that far away. You are welcome to use it if the need arises. :tup:
