Pt-72

[turbo grey]

Hi guys,just got a PT-72 the other day and was wondering if anyone here using one has any feedback??
such as how you like it,spool up characteristics,and performance
et/mph.
also I will be i will be needing an inj upgrade,and was thinking 75's would do the job,but a friend suggested 83's??
thanks.

I would say use the 83's with that 72 turbo...you'll be guaranteed to have plenty of fuel...that's a honkin big turbo ya got there

Ill be running a LT 72 P trim .63 A/R.


Only thing is,why dont I see more people running this turbo??And I know a q trim wheel is more effecient so....

The .63 is really choking that turbo, and makes for a inneficent combination. The compressor side is huge, and but that housing wont allow all that airflow through the motor, thus horsepower is serverly limited. If you go to 4 bolt/ .81 a/r and have enough stall, 4000 plus.......you would pick up at least 75 hp at the flywheel. I run a 68 a/r 4 bolt and i picked up a solid 4 mph over the .63 garret 3 bolt, have you ever looked inside one???????moussy!

With a 72, I would go with a 72GTS. Using the new GT wheel. Much more efficient and you can make another 50-75hp.

This is the turbo that Limit reccomended to me.I spoke directly with John C about it. I dont want to swap to a 4 bolt as my ATR headers are 3 bolt.Unless someone knows where I can get the adapter from...

I made one from a piece of soilid 3/8 steel, i think turbonetics makes one. once you go 4 bolt you wont go back!

lol

I guess when your running a 76 turbo on a stock block,3 or 4 bolt isnt that much of a diff.

You wouldnt still have that 4 bolt housing or an adaptor would you??

I have a 3-4 bolt adapter, pm me with an offer if your interested.

Thanks.

Sorry for whoring up your thread turbo gray

Go with the 83s. That is plenty of injector for that turbo.
