Guys and gals...
I finally got this turbo installed after having it for months waiting for the weather here in lovely Alaska, err, ah, I mean, Michigan to break. :smile:
This turbo is replacing the OLD faithful and trusty T-63-1 (3in inlet, 2 1/2 outlet) with a PTE .63 housing. I was using that with an "O" pump, real Art Carr converter. And it spooled OK, to not bad at best. From the right launch or roll it was sometimes better.
The new 62-65 DBB was installed with an .85 PTE ex housing and otherwise the exact same set up. I am using an HKS external gate to control boost, and thoroughly ported the wastegate whole to 1 1/2in, which is the max for my downpipe and gate. A little background info here... At the end of last season I was able to clip off a couple 10 second runs with 25psi with the 63. Then promptly turned the boost down to 20-21 as I left the track very happy to have those 10 second runs finally under my belt with the car. So, after all the porting, and the initial drive, the boost with the new turbo is just about 25psi with the same wastegate setting.
Needless to say, I was suprised to see the boost so high. But, with what I have heard from a couple vendors I shouldn`t of been to suprised.:wink:
The new 62-65 DBB turbo spools WAY quicker than the old 63, even with the 85 housing installed. It feels like I put a TE-44 on the car as far as spoolup goes. I do not have any numbers from the track, but it feels at least as good, if not better on the top end as well. I have been out tuning the new combo, and have been suprised at the mph it has gone during my WOT pulls. I actually did not think I was going quite so fast. I guess that is a good thing.
In closing... I am VERY pleased with the feel and performance of this new turbo. On the street, there is no comparison. It is WAY BETTER! If you are on the fence about this turbo, grab it. You will not be disappointed!

I gave mya "dial a gasket" a full turn, and fully expected 2-3 psi more. Not to be. The car saw 23 psi through the traps and went 10.905 @ 122. The 63 that came off propelled the car to a 10.84 @ 125 at 25 psi. Keep in mind, this is a stock cammed car, and I go through the traps at 5400-5500. So, your numbers may vary!
