Pt-67

[Sal Lubrano]

Just my experience.
I was running a pt51 and I thought my car was fast. Well, let me tell you the 67 made my car feel like it was standing still with the 51. I have been running the 67 with 19 psi for a few weeks and I just turned the alky and boost up. WOW Hold on TIGHT. The turbo just woke the car up in the 22-23 boost range. I can honestly say that it is took fast to be driven on the streets. This turbo sprung in to action with the few extra pounds. I wounder where it starts to fall off? Need to get to a track for some tuning. The reason I went with this turbo is because the te-45a required too much boost for pump gas to be efficient but this turbo falls perfect with pump and alky. Highly recommened.

Totally with you on this one. I have been running my GT67P for a few weeks now. Even with the stock D5 converter it was brutal on the street. My setup is a RJC Hybrid Boost Controller and Razor's kit at 24lbs boost. It has instant jailtime potential.
I just installed my new 3600 stall and new ATR crossflow exhaust this weekend. I am just itching to give it a blast when the rain stops.

Sorry but I dont mean to steal your thread but I had a question. I keep trying to find more info on these turbos that everyone mentions. I get good info from some of the vendor website like Full Throttle and others but what keeps throwing me off is the names of the turbos. Is there somewhere I could go that list "all" the turbos we use for the GN's? I get confused between PT 67, 88, 71 , 51 ect ect. Some have four numbers (ie GT 6152, ectp) and others have different designations after the number (ie PT 70 GTQ,-P Trim, ect) I just want to know whats a good turbo to run on bolt ons and stock convertor (which I will upgrade later) and is mostly street driven on weekends and stuff, not a daily drive. Dont care about fuel economy. Just want power with least amount of lag as possibly. Thanks and sorry for stealing your thread!

My street T Type went 12. 85 @ 115( 2.0+ 60 ft) with big valve unported heads and stock portmatched only intake,converter unlocked at 15 psi on pump gas. The 67 is an awesome turbo for low boost apps.

What setup is required to run this turbo,inj.,stall.......and so on?Anyone got any times?

Basically there is a ta-te-pt-cpt
Ta is a stock appearing compressor housing(two bolts for the inlet bell)
Te is a one piece compressor housing
pt is a precision brand turbo. Garret made our oiginal turbo and has stopped making exhaust housing. Precion has picked up the market and made thier housing and turbos.
Cpt is jack cotton turbos I belive made by turbonetics.
Also go to gnttype.org under turbochargers. Great info.
There is also the new gt which is explained in the thread above. Too much info to type. Just search and ask questions. Basically you need to ask yourself how fast do I want to go. Start there and we can help you on your path. Good luck.

I've had the PT67 for 3 years, since they first came out. It's awesome on the street and strip. Little turbo lag on the street and at the track, I ran a 10:78 @126 in Bowling Green this year at only 21 lbs boost on d.o.t. tires and the car weighs 3675 with me in it. I don't see how you could find a better turbo!!! Paul

 

[XxDarkSidexX]

this turbo seems to be bad ass. I was thinking of a t66, a 70 would be to much for what im trying to do. But the pt-67 is quickly embedding a good impression on me.

Mid to low 10's seems to be what this turbo is best for? 10's on 21lbs is exactly where i would like to be.

 

[my 1st gn]

is this to much turbo for a stock unopened motor.

 

[Sal Lubrano]

A 66 is a te-45a which requires more boost to put it in the sweet spot. From what I have heard the 45a will make power above 25-26 lbs but the 67 gives up at that point but makes more power below that. The 67 is a much better turbo for running pump and alky and the te-45a is better on the track with race gas. I guess it depends on what the caris being built for? I have a 67 on a stock motor with a mild cam. I see no reason why not to skip the small upgrade and just go for it as long as you have the money for the other mods required with this turbo. I.E. Injectors, chip for injectors, a good stalling converter and a good intercooler which is not necessary but the turbo will run like crap without it along with a good exhaust. Just make sure the car can handle this power such as the trans, brakes, rear end. The list can go on forever.

what were your times with the pt-51

 

[Sal Lubrano]

I have never had this car to the track but it was a big difference between the pt-51 and GT(Pt-67) The new garrett compressor wheels are really amazing. It all depends on how much $$$ you want to put in to your build. I also selected the 67 because it is more than enough to break the short block in to two with out having a girdle put on. This turbo will easily get to the tens and a few have made 9 second passes with it and it is totally streetable. I guess the only turbo better would be a ball bearing but the price will reflect it. I believe ful throttle sells these for less than $800 but there are many options you can get which will up the price. Such as a Q-tim turbine. Larger inlet and outlet compressor cover. Larger Air radius. You might even be able to get this turbo ball bearing but not sure.

I just installed my new 3600 stall and new ATR crossflow exhaust this weekend. I am just itching to give it a blast when the rain stops.

So how is this turbo with the 3600 stall converter ?

Also as an aside, PTE was at the Indy event and on their table was a PT6776P Dual Ball Bearing, the price did indeed reflect it at about $1400 (?).

But I would guess that with the BB option, a tighter converter can be used.

i have a 3200 converter and its fine...3600 would work great but you dont really need all that converter...

67 vs 63

I went with a PT67 from Limit on my fresh 3.8. I should be able to run 16-18 lbs of boost on pump gas and make good power. I will add alcohol injection soon to increase the boost a few lbs. For a street car this should work well. I have a 3500 Pat's l/u converter also. I thought about using a 63 but I would have to turn up the boost, change the chip and run higher octane to get the same performance as the setup I went with. I hope to fire the engine in the next couple of days. Still working on installing a GNX dash from Performance Instruments. Taking a little longer than I planned but it will be worth it!

 

[XxDarkSidexX]

dam the more i hear about this turbo the more and more im wanting it!

lets say with je's, 218/218 cam, huge FM, 72'b injecters, 3" ex. turbo back, and alum. champion heads with a maxed port n polish, T&D 1.65, walbro single pump (hotwired). 3600 n/l art car, built tranny by DRW, and built rearend and 8 peice hotchiks kit for suspension. And small other goodies like 70mm TB, port matched intake, relocated battery, shift kit, air bags, ect ect.

So I have 3 questions.
#1 is this set up usable for a stock ecm unit (modded of course w/chip and for low imp. injecters)?

#2 will California 91 and alky be able to hit 20-25lbs of boost on a pt-67 and a stock modded ecm?

#3 Or is this setup really begging for a stand alone computer and a bb 70? Can the experts and pt-67 users chim in?

****EDIT 1 more question; with this setup what AR would fit best? Would a .63 housing P trim work well for my set up, or would a .85 work better with a GTQ wheel? Thanks guys.

 

[XxDarkSidexX]

did a search, read everything on pt-67. Couldn't find any updates on Dual Ball Bearing 67's??????

Looks like 72's inject will work great with my single walbro 340. And the gtq wheel is the way to go with a .63 housing. Along with alky and heavy tuning on a modded stock ecm, 10's should not be to far out of reach. Given that everything else is ready for 10 second runs of couse, but just focusing on which turbo for my motor. I would love to stay in the low 20's of boost with alky and be scratching the surface of 10's.

off to a late lunch and then the angles game, researching this turbo business just burned 3 hrs. But I can't HELP IT, this 67 looks pretty bad ass!

 

[Sal Lubrano]

Let me know what you think of the GTQ trim. I chose the p-trim for two reasons.
1. Price
2. Car is purely street driven and I wanted to limit my spool time.

Just my opinion.....but if you are going with a 67 I would stay with the P trim exhaust wheel. No reason to go with the GTQ. If you want more flow, then go GT70 P-trim. That is what I am using and it only spools slightly slower than the 67 I had on before.

What exactly is your goal ? You mention running 10's.....well you can do it easily with a 67 P trim and max ported heads. The 218 cam is a little large for a street car IMO....but I like tighter converters and good bottom end torque.
