I have had a pt-70 gtq .91 hot side on order for 2 weeks now. i just found out that it will be 2 more weeks before they get the parts for the build. Is there any other turbo that is about the same or does everyone think i should wait it out. I am ready to get on the road. By the way he didnt sound sure about the additional 2 weeks.

 

Is there anyone here using a precision turbo.

 

Garrett has a huge backorder right now. I have a ton of people waiting for 35R's for quite awhile. Precision and others are stuck waiting as well. Sucks to be a vendor/distributor right now.

 

it sucks to be a customer right now too. it looks like i will have to bolt the stock twins on to make it to the gap.

 

well guys is there any other turbo that anyone recomends of the same size. i really want to get finished.

 

Yeah I bought a PT74GTS-H about a month ago and it only took 2 weeks to get the turbo. It was a special order turbo and I got it fairly quickly. Who did you buy it from? Is it directly through Precision or getting it from a dealer? I got mine from this place http://www.theracingstore.com/turbos.html good luck.

 

i made the order directly through patrick at precision turbo. i could have got it with the sh trim but i dont know much about it. what mods do you have and how does it perform?

 

i guess i should list my set-up. half bridge with new housings, 850 prim.,1600 sec.,aeromotive a1000 fuel pump, haltech e-11 v2 all new internals from atkins 2mm 2 piece seals, water injection kit, custom turbo manifold, custom 3 row inter cooler and ect... i never thought to ask if this turbo would be a good choice!

 

sorry guys. the turbo is a .96 hotside.

 

Yea, you could just get a Garret T70. The PT turbos are basically just Garrett turbos with a unmarked Holset compressor housing.

 

my pt63 took 2 weeks to arrive......i did order 2 months ago tho

 

Look at my Vbgarage https://www.rx7club.com/vbgarage.php?do=view&id=58067 I don't have it up and running yet hopefully by the end of summer I'll have it runnig but a friend of mine with a steetport 13brew on alcohol has made 680rwhp with this turbo. I'm going to run VP C16 and conservatively shooting for 580rwhp because my friend has made that number on gas and I have his old setup so I should definitely be able to meet that goal. I just want to make it reliable I'll be happy if I can make 400rwhp seeing that my Datsun 1200 is still on stock leaf spings and will be a handful to drive being under 2000lbs with me in it.

 

With a 1/2 bridge you may want to go with a larger A/R on the hotside.

1/2 bridge's breath alot of air, i'd recomend a 1.15-1.35 you will be able to actualy use more of your topend (im asumeing ur reving to 9k?)

 

so a larger hotside will give more top end. what about spool times?

 

if i go with a 1.15 a/r what trim should i go with. they have the q, p, and the sh.

 

does any have any idea what the s or sh trim is. they actually have this in stock.

S trim is the turbine wheel size which is larger than both p and q. Ralph at Ground Zero uses a PT70 with an S-trim. He's pushing 650rwhp all street.

Don't know if Precision makes an ar larger than .96 for the PT70 but if they don't, an S-trim turbine wheel with a .96 ar will do just as good if not better than a larger ar q-trim

Precision is having a hell of a time getting turbos out to customers right now. Bigger turbos like the T88 ship out real fast though. Bought a PT91 and a PT101 and got them within a week

thanks lt1-7.. something wierd happend with posting last night. i never saw your post and it looks like you didn't ethier. thanks. i think i will call precision today and check on the s trim.

 

so lets go over this. the larger the trim the more lag and the more top end. the smaller the trim the less lag and better mid to low range power. thats the way it looks to me right now. also are you saying that the s trim is bigger that the p and q trim, sizes smallest to largest is p then q then s? ethier im getting really confused or im halr way right.

 

ooops. thats half way right.

 

yeah this turbo will be worth the wait. I am waiting for my setup now aswell and I am looking a another 2 weeks. If I had went with a large port I would have most likely got the same turbo as you. What manifold are you running? Divided or Undivided?
