PTE 71 GTQ 4 bolt .81

[turboclam]

I can pick one up locally NEW for $650. It's such a good deal, should I just go with it? Would it work well with my combo? I was leaning torward the 71 HPS ($800 more) but is it going to make that much of a difference? Street car. Thanks!

Here are the specs...

Precision 7168 GTQ TRIM Billet Compressor Turbo
rated at 945HP
71mm compressor and 68mm turbine wheel
HP Cover with anit-surge porting
4 inch inlet 3 inch outlet
81A/R exhaust housing standard T4 flange
zero miles on turbo

Sounds like an excellent deal for you if have the proper converter to go with it like a 4-4500 stall.

Yep!! Listen to Nick!

That's a good deal! I have a junior build of yours. 247"(109), T/A S/E race port hds, 212/212 roller,etc, I have the 71 GTQ 3 bolt coupled w/3500 neal chance converter and yes it has a lag when kicked down in a roll on the street. From a red light and a chance to build a little boost!!!!! If you are looking for instant power, It would require a shot of nos! or a higher stall:frown:. I just purchased a T-ntics hp-76 4 bolt b/b(used), last month but I'm saving it for the rebuild. so no help there.
The question will be, can you live w/the lag? Also, higher compression helps on the street. I 'm @ 7.8:1:redface: w/the 55cc heads.

OK, I picked this turbo up today and it looks really good but...................................after inspecting the compressor housing after I got home it says 7180HPS. ,...............and he took $550.

The 80 is basically the older version of the 68 wheel.
It should be very similar.

What does the HPS mean anyway?

What does the HPS mean anyway?

H = 4inch Inlet and 3 inch Outlet
PS = Ported Shroud, for anti surging

Thanks for the info! So do I still need a 4000-4500 stall to run on the street?

anything below 3800 = weak kneed puke ..

What about the Sound Performance flap that thi imports are using for quicker spool up. Anyone try it?

Talk to Patrick at PTE, but he rates the Journal Bearing at 3800 min stall.
I had a 4200 stall with my 70 P trim and 3.8 back in the stone ages.
I could have gone tighter.
With extra cubes and compression I would hope you could do it around 4k.
Who is doing your converter?
I recommend speaking to Dusty Bradford.

I lied, HPS is what they call a specific turbine wheel.

 

[DR BOOST]

7168 is a hpq71

7180 is a gtq71

No, you were right before. H is the cover and PS is for the ported shroud.
