Which PTE Turbo?

[BoostedSUV]

Debating on taking the plunge on a new bigger turbo for my build. Looking at the precision PTE6266, 6265, and 6262. Sticking with precision since it will be a direct bolt in for my current setup

My build is 63lb injectors, 3000 stall 9/11, vortec heads, 422 cam, BBK 52mm throttle body, RPM A2A, SRP pistons, Eagle rods, MSD, meth etc..

Looking for a great street monster, not a 'need a 2-step to spool' drag machine. I want quick spool up and a good turbo for 90% street driving. Not looking to upgrade injectors or throw anymore money out there either. Not wanting to set records, just want a better turbo to suit my build. looking for maybe mid-high 11's at 115+

Also I currently have a 3" cobra elbow and 2" outlet so I was going to go with the "E" compressor cover. Would going with the "S" cover (4" in, 2,5" out) really make that much of a difference to justify the other changes to go with it? Suggestions? I'm not a turbo expert, so I listen to the guys who know their chit.

Re: Which PTE Turbo?

Any of those turbo's would work for your application. From what I have read the 62 compressor wheel would see some gains with S cover. I don't think you will see huge gains but its upto you. I think the potential to run your goals isn't going to be hindered by a E cover either though.

I have a PTE6131BB with E cover (slightly larger than the 6031 you have), personally once I build a short block I want get a 6262BB & S cover. That should be good enough to run 10's in a Syclone with a good tune and traction. The turbo buicks are on the edge of running high 9's with a 6262.

Re: Which PTE Turbo?

I run a 6265,ulta quick spool and pulls like a bitch,you can run as low as a 2600 stall coverter.The new 6266 is worth about another 35 hp (735hp).

Re: Which PTE Turbo?

Thanks Dave, I figure any of those 3 turbos would be suitable for my build. I don't want to over turbo it, but I also don't want to spend the money and know I could of gone bigger. I have zero intentions to change my build in any other way other than MAYBE injectors in the future if I'm maxing them out and want more.

As far as "S" vs "E" covers, if I'm going to spend the money for a turbo I'm not going to let the cost of cobra elbow or a new coupler for my A2A make that decision. However if there's no real gain going to an "S" cover than I'd rather save that expense. Hmm decisions.... All 3 turbos are pretty much the same price so that's not a deciding factor.

Re: Which PTE Turbo?

They will all show little difference in the overall picture for your truck. The 6262 will spool quicker on the street and will probably make a slight noticable turbo whine driving as the smaller exhaust wheel will be spinning decently even under vacuum conditions. The smaller exhaust will flatten out quicker under higher boost. On the other side the 6266 will spool a little slower but pull harder on the big end as it can flow more exhuast.

I would go with either the 6262 or the 6265. Your converter will spool either ok. Being you have a TY (heavier) the 6265 will give some added beneifits at the track at the big end. For the street and low to mid range quickness the 6262. If you are running meth your 63#er should be fine for either.

I run the 6265s on my twin turbo setup. It's a total different application, but they have worked well.

jack I still see the 6265 on precision s website but I spoke to someone recently about purchasing a turbo and they said the 6265 has been superseded and the options are the 6262 or 6266. Not sure how that true that is? :dunno:

Re: Which PTE Turbo?

I've done a ton of research because I am at the same crossroad. Everything I've read and all the people I've talked to have pointed me to the 6266. It pulls hard and is rated up to 735 hp. I believe that is without Alky. Just the info I've come up with.

Re: Which PTE Turbo?

I know that youre still good with the 63#'s with any of those 3 turbos,so that's not a problem.Brandon went from a 70mm to a 6265 non bb and pick up a lot of speed and hp.Mine is the dbb unit and I really like it.

great info, Thanks John. That's what I'm looking for

that's what I'm seeing too and what I'm leaning towards

I would love to go DBB but I can't justify the extra $600

Why run a 735hp turbo when it's more than needed for built stock blocks and vortecs. it's wasting the efficency of the exhaust wheel. The 6262 or 6265 would be more efficent for the 500-650 hp range. Better spool up and drivability. If bigger is better then we should all be running 88s...

Not busting stones here, but putting some reason for running turbos that can best use their efficency.

The pte61 use a gt35 compressor wheel. If I remember right the gt35r uses a 60mm turbine wheels (I know it's sizing is between the 57 & 62 turbine wheels that pte used to use), so it would be theorectically numbered as a 6160 in the current pte naming scheme.

certainly a valid point, I am by no means trying to push 700+ hp. 600-650 yeah but I'd like to have room to grow if need be. if a 6266 isn't going to overturbo the truck to the point is spools so slow I hate than I think it's a good option. If that's going to be the case I'd step it down to a 62/65

Re: Which PTE Turbo?

So what did you go with? 6262 or 6267? I'm debating the exact same two turbos.
