What could I expect with switching out my 6262 precision with 6262 Garrett

I know, sounds weird right? But yes, I have a couple turbos. The current 6262 PTE I have is fine, pulls well, spools fine. But, I also have a work turbo 6262 as well down stairs with an 11 blade GTX35 MFS Billet wheel. From what I have been told the wheel is a beast. I remember this turbo being a pretty nice turbo, but have done alot to the setup since I ran this turbo. Since it appears I will be taking my headers off I thought about putting this turbo in and seeing how it does. What I am looking for is anyone that has experience in using the garrett 63 turbine housing with a 62 wheel, and could I expect more more spool quicker, but less top end? The compressor cover is a .70 garrett housing.

The garret .63 ex housing needs several hundred less rpm to get the turbo going in general.inmo I would only swap turbos to pick up on the exhaust side as that usually is the limitation if the compressor has the ability to flow.your shift rpm and motor compression should be matched to the turbo you choose.i personally like the 65/66 turbine wheels on motors with heads and cam as they go further up the rpm range with the right comp wheel.My thought is on both your turbos the 62 ex wheel is the limitation especially going up in the rpm range the smaller ex housing further limits the rpm range but needs a lot less ex gas to fill,spooling the turbo up sooner.
 
I am pretty happy with the performance of the PTE6262, my question was pertaining to if using the Work turbo with the garrett housing, what would the manners be like? I know and have heard the garret will spool quicker. Based on progressions with my build, maybe the garret will spool sooner and make seat of the pants more fun in street, but on track runs the garret would hinder. If this is the case, I would have a very nice turbo that would need to be sold off for someone with a more stock type setup (stock converter, minor mods, etc)

Ok I will try again.the garret .63 generally speaking needs 2/300 rpm less converter to get spooling.so if your converter is on the tight side the turbo will be more responsive.looking at your sig your turbo should be spooling really fast if the converter and tune is on point.either turbo you have will spool really fast if the converter has the right initial and flash stall.
 
ok let me try as well. Will the smaller garrett hurt top end, word has it the precision .63 is a little larger than the garrett .63

Yes, going to a smaller housing with hurt top end. Pte.63 is actually more like a .77/.78

The garret is smaller than the pte.will your car slow down depends on how much power it makes and the shift rpm like I stated.
 
If you run 20psi and shift at 5000 rpm the garret in most cases will be faster,now if your looking for 30psi and 5800rpm shift points the larger pte may be faster.
 
My car dropped 2psi or so over 5400-5500 rpm @ 26-27psi boost..Switched housing and pulls clean to 5800rpm.

Thanks. Appears I need to sell this Work 6262 to someone with less mods to take advantage of it.

fyi, the car made 575 on 19lb 6000 WOT rpm E85 with the 6262. THis was on a mustang dyno.

At that rpm and power range I would not be looking to move to a smaller ex housing especially if your happy with the turbo response.going to a bigger turbine wheel and larger com wheel would be your next step.fyi on one of the stroker motors here it made 698 rwhp at the same 6000rpm but the turbo is a 71hpq dbb.
