I know the PT-67 turbo is capable of low 10's and uses a GT compressor wheel and a 76 P-trim exhaust wheel...for $25 more from PTE there's also a PT-67 GTQ which the only difference is the exhaust wheel and it's a GT series exhaust wheel...are these two turbos really that different...and why is a 66 higher priced than both those turbos? i'm just trying to find THE best big shaft turbo that will not cost over $1100 and will be able to handle 95% street use and spoolup great with a 3500 PTS 9/11 l-u billet stall converter :zahn:

Finding a GT turbo that big under $1100 is going to be tough, unless you get it used. I believe they go for around $1500 new. I have not yet gotten my price list, so I can not tell you what they will cost.

You may want to call Innovative Turbo Systems here in CA.

A twin ball bearing 70 or 66 will do what you are looking for.

Spool is the last thing you will have to worry about.

From what I remember from a few PT67 turbo owners was that the 67 was the new equivalent to the old T70 if in the same housings. IF you go with the Q you need to stuff it in the .85 housing. The exhaust wheel (I believe) is 5mm bigger than the P trim. You are probably looking at a 50hp increase and a much slower spool over the PT67 .63 P trim.

I am going PT67 in the .63 due to 99% street driving. I want low 11's with alky at 23 psi on Dot's and a comment was that it spooled like the TE60, but probably resembles the TE63 due to garrets new wheel design.

Sounds like a winner to me as it went 10.9 at 19 psi in the .63 on a TB.com members GN.

What size injectors do you think would best compliment this turbo?

FYI the PTE P trim 67 is a small shaft turbo. If you go with the Q trim option they make it a big shaft turbo.

Bap30, IMHO 57's would be a minimum with that turbo. 72/75's are probably a better idea.

Clayton, I think I have decided on the Siemans 72#'s with a double pumper setup. Are you sure the PT-67 p trim is a small shaft? I thought I read where it was a big shaft as well as the q trim.

I have had two different discussions with Joe Lubrant and Jim (the builder) @ PTE. Jim assured me that the PT67 P trim is on a small shaft and the Q trim is on a big shaft. Believe me, it seemed weird to me too, but that is what he said. Since he is the turbo builder @ PTE I figured he knows what he is talking about.

It makes me a little nervous having that big of a compressor wheel on a small shaft which is why I chose not to go with the 67 at this point. I'm not saying it is a problem, since I really have no idea, but I would feel better with a big shaft trubo when dealing with a compressor wheel and turbine of that size.

ah somebody revived this thread...

i've heard lots of good success stories with the 67...but now I have decided to step it down to a PT61 since I am on a budget now! (funny how that works)

there's a guy named Jay Banning who has the 67 and ran like 10.97 on only 20 lbs boost...

I have the gt-61 from limit. Just finished putting it on today. I have the stock d5 coverter and when the car is in overdrive and cruiseing at 50mph the lag is terrible while slowly accelerating. but when i put it in drive it spools fine. I did a brake torque and was able to build 5psi on the brake then the tires broke loose and i had some pedal left. I will try it at the track w/ the d5 and see how i like it. I have about 100 oct. in the tank and hit 20 psi WOW what a differance from the stock turbo.

I have decided to go with Limits LT67P which is their version of the PT67. John Craig says that theirs is a big shaft turbo, 4" inlet, 2.5" outlet. I have had great expereinces with John in the past with quality and service. No doubt that this turbo will be superb!

Is this the name that John is calling the turbo? There's so many choices anymore its hard to keep up with the letters and numbers!

Keith,

This it the name of John's 67 turbo. Same turbo as PTE PT67, just built by John and the good ole boys at Limit Engineering. BTW, Farmington should be the first place I test this thing when everything comes together. :rock:

What converter & stall are you gonna run? I may have to call John and Chopper to get an update on available turbos.

Keith,

I will be running a 9x11 billet with a 3200 or 3400 stall. Leaning more towards the 3400. This should work well with that turbo I think.

My experience with the 9x11 converters from Bruce is that they are always built looser than what I have requested. (3 different converters in 3 different cars.) This may actually help you in the 1/8th but will definitely hurt you in the 1/4mi. You are allowed a free stall change in the 1st year though. If it is built to what you spec. them I would recommend the 3400 stall.

How much $$$ is he asking for his version?

Thanks.

Nearing,

I think $1200-1300 for the LT67P.

John Craig assures me that the 67mm wheel on the small shaft will not be a problem at all!!

The small shaft version will have a quicker spool up right?

Taffy

Not sure exactly. I would not think that the spoolup would change much with the size of the shaft.

I am gettin the 45a for my RB25DET though. I am expecting 650 at the wheels!!

1) Just call me Banning (my middle name)

2) On several runs i went 11.0x & 11.1x with 20psi... but I had to turn it up to get that 10.97. Boost was about 24psi... BUT it was the end of the day and the intake/intercooler was pretty heat soaked. My fueling was all wacked out too.

with some good tuning that beast should be flying!...that turbo is sweet...I might get it when I get my motor totally rebuilt next year...but by then they might have something even better...who knows...sticking with the stock stuff again this year while i still have SOME cash
