garrett is smaller and spools faster, same a/r but you can seeeeee the difference when they are side by side.

Precision housings are designed for maximum efficiency and flow. The garrett housings MIGHT spool quicker on a given application but the difference is so little you won't even notice it. I ran a TE44 on a stock converter with a .63 Precision housing and it spooled just as quick as stock.

I agree, when i had a 44 on my stock D5 it spool like a dog with the .63 PTE, but i loved the turbo...
My HD wastegate was tight as a drum, and it wasnt the puck not seating. Definitely not anything close to the stock turbo spoolup.
Now the RJC valve is out, so i can retract that statement lately, 44s spool fine with erics chips and a RJC valve with the D5, just like the stocker.
Pte housings spool slower and offer about 1 mph more than the garrett .63, the PTE .85 is another 1 mph more than the PTE .63 ON MY CARS...
Been there and done that on multiple cars here in KC, all have PTE housings :biggrin:

TE44 here with the Precision .63 housing.
with the stock converter it was slow off the line. especially if you were caught off gaurd and had to punch it without power braking
.
now i have about 3200 stall and it spools quicker than stock.
if you are going to get a bigger stall you might as well get the PTE housing just for the TINY bit of extra top end flow.

Because of the elevation i am at the TE-44 and Precision exhaust housing is slow to spool with a stock converter. For the local guys around here i suggest that if they want a TE-44 then use the garret .63 housing. You will be much happier with it and still be capable of 11's. if you go to a 63 or bigger then definately use any of the precision exhaust housings.

I always suggest the te44 because it does have really good top end and its a proven turbo that lasts.
Does the gt3255 make as much top end power as the 44?
Got a link?

I have no idea...can anybody with a GT3255 chime up? I would think on a street car, you would want quicker spool and more lower end torque which is what the GT3255 provides? you guys tell me! I used to run a 44 so I know how that responds...
We find the same thing even at sea level. I've had a TA49 with a Garret .63 and a TE44 with the PTE .63. The 49 definately spooled faster.
For more fun on the street the Garret is the way to go. IMHO, at the track the added lag of the PTE housing can be easily overcome with the proper tuning, and just launching a little harder

spool-up
my helped my friend BarnesGN swap out his pte.63 housing to a garret housing on his ta-49 and it made a big difference to it in the street.
i have a GT61-52e with a 9/11 3200 stall and with the car tuned it spools faster than the stocker.
i tend to tune the car to be a bit rich on the bottom end so it has some lag to it. if not the rear end tries to pass the front end
the car is a little bit more controllable with the lag. but when it comes on hold on.
also what is a gt61-52e compare to? a pt61 ??

I'm running a PT6152E and I'm glad I skipped the smaller turbos. I have a 3K stall converter actually setup tuner style now with a HD wastegate and have no problem smoking the tires in 1st and 2nd from a roll or stop. It hits 20 psi real quick and the 245/50 R16 tires just let go. It has the Precision housing and pulls really well on the highway especially when the converter locks. I'm sure the heads and cam are contributing to this. I can't wait to put it on the track with D/Rs and see what it does when I can actually use 1st and 2nd gear.

I'll be honest that I don't know much about this turbo... But I run Limit Engineering Ta/Te61's w/ Garrett .63 housings on a few cars in my area. Some of them have or had the stock D-5 in them at one point or another. Tuned properly they spool great and pull low 11's all day long with mild bolt-ons.
The latest bolt-on car went 11.4's @ 119mph with conservative boost and tuning.
PT61, GT61, 6152 are all the same turbo...
The TA61-TE61 and the PT61 are completely different turbos...
I think we went a little off topic...I was curious to see if the GT3255 really does lack up top compared to the TE44 which I don't think it does but somebody prove me wrong! Again I used to run a TE44 with a Precision housing and it did NOT spool slower than stock...so I find it hard to believe the Precision housing is really that laggy...IMO it's all in the tune
