I did have a T 70 , it boosted quickly and pulled real strong , but its not comparable to my "new " turbo!!.
I run a half bridge with a TA 45 / 51 ("special") - 76mm comp wheel and a 71mm turbine wheel. 10psi (WG pressure as I couldnt get the EVC to hold the boost ) of boost is available from 4500 RPM up , the **** really starts to happen past 5000rpm. I got it up to 15psi in third gear whilst tuning a few times and it was scary as **** !! , I couldnt't even hold the RPM's past 7000.
I have since sold my boost controller and will be replacing it with a better one so that I can get the boost to 25+ psi.
I have also broken a few parts (2 diffs , 2 clutches & a PPF ) and am replacing/upgrading them as I go , I personally prefer a LARGE turbo , but it has to be PROPERLY matched to the motor and you HAVE to compramise a bit when it comes to all out power and response. Although you don't see 20+ psi on the boost meter by 3000 rpm , you sure as hell feel a similar or even greater pull but at a lower boostlevel !!.

If you are going to be running a large turbo, why not step up to t51 series? You get the bigshaft option and all the bearings, etc are more suited towards heavy duty usage, which more than likely means a longer life. I have a brand new Davinci: custom Garret utilizing a 76mm comp wheel, jet hot coated, .96a/ near exact same dimensions as HKS t51spl )i am going to have to get rid of.Let me know, also got a HKS 60mm racegate, and a blitz bov too.

I used the NPR large ic that I got on thr parts trader for $300 , all the piping was done using 3" aluminum pieces that I got welded on work. The exhaust manifold was made of schedule 40 steel "steam " pipe and elbows , wastegates and bov are tial ( cheaper and better than the BIG brands , in my opinion)

Marcel, did you bust your diff, ppf, and clutches from launching the car? I'm hoping I can get by without replacing a few things since I'm not going to be launching the car. Please tell me you didnt bust your diff just from rolling into it
Thanks
STEPHEN

You have an idea of the power you were making when you busted the ppf and diff just from spirited driving? Was it from the boost kicking in all the sudden and just busting it to hell and back or what? It wasnt from wheel hop or anything like that?
Damn, that sucks....I'm not running 315's but I do run drag radials all that time

No I dont know how much power yet , I havent been able to get to the dyno yet ,I keep breaking things . With a large turbo like I have it builds gradually to 10 psi (my WG pressure) till around 4500rpms , after which it spikes past the 10psi (when I had the EVC working).
I have also maxxed out my A1000 at the 15psi , so I am again limited until I get my twin BOSCH '044's , I also sold the EVC to get an e Boost , I am quite sure the boost rise would be faster , since I use two 35mm gates that bleed off a lot when they start to open up early. The only thing left to break / upgrade now would be my axles.

10 psi . As is said , 10 psi on a large frame turbo is like 15-20 on the smaller ones . I had my car bone stock with the twins working perfectly with 10psi boost by 1500RPM and I am quite sure that my car is a lot faster now !!!.

How many miles were on those parts? I been running 18psi on BNR stage 3's making over 400rw for over a year and never broke anything. Surely your not making 400rw or more on just 10psi of boost

Please tell me the ups and downs of this turbo.... Some feedback please...
thanks
Also please tell me how much boost i would be able to run on this turbo and how much better would it be from the twins. The spooling and the top end?
Please help...

Well the only comment I can give you
is you wanted to be cheap so you got a cheap turbo
a T 70 has 70mm wheel
the Super T70 you won has a 60mm wheel
aka 60-1
I belive it has a T3 flange
you will need spend upwards of 150 to change the turbine housing
It should work
any turbo would work how good? is the real question

Can you send an ebay link, a T-70 should have a 69mm compressor wheel.
THE BEST OF THE BEST:
BRAND NEW IN THE BOX!
SUPER 13B TURBO
MONSTER STONE " T70 "
FOR A GREAT POWER BOOST
WET FLOATING BEARINGS
WET FLOATING BALL BEARINGS
SHAFT & WHEEL TRIM 64.5mm
COMPRESSOR WHEEL SUPER 70 60.5mm
TURBINE HOUSING A/R .84
COMPRESSOR HOUSING A/R RATIO .70
I am sure now that is not the complete truth... but what is... I mean i just registered today on e-bay and in the excitement placed the bid.. Please tell me the ups and downs of this turbo...
I did not want to be cheap its just that i thougt it was too good a deal to pass on..Never had i thought it would not be true... Actually a friend on mine is using a T04e i think with an A/R of .60 and still his car is very fast.. i thought since this turbo has better A/R it would have more power...
Please tell me how much Hp would this turbo be good for and what sort of spooling should i expect
thanks

They have been selling those turbos for a while
now
Yes The price is good
and they have half-a-dozen of those turbos for sale all the time no real OMG factor to rush and buy
If your on a budget
then I say go for it
It has a T3 flange
you will need to make a custom T3 manifold
or change the Turbine housing to a T4 which adds to the cost of the turbo
ok 1st
almost ALL Turbonetics or PT
names reflect there size
(rounded off)
a 60-1= 60mm
62-1=62mm
PT67= 67mm
T-66= 66mm
T-70= 70mm
T-76=76mm
etc
for mazdas
.81-96 turbine center housings
1.00-1.32 Tang turbine housings are optimal

Old thread,but I ran a t70 on a street port. It had a
.96 exhaust ptrim. Full boost by 4500. I don't think
these are good for drag racing/street because their
sweet spot is way up there- 25+psi.It pulled like a
freight train up top, but lag was an issue between
shifts. I think a t66 or gt67 would be better. I have
switched to a gt67 .81ptrim and it is a much quicker
car. Still have to tune to get#s hopefully next month.

Thanks guys... Having a manifold and downpipe fabricated is no problem for me.. I will make a custom manifold and downpipe just please please tell me i can make more than 400hp with this turbo... and also that it will spool before 5000rpms... I think for what i am paying for it i do not ask for more.....
The only confusion still there is that what actually is the A/R of the turbo?? They say 0.84 and 0.70
Is that true??
Thanks alot guys... Please tell me it is not a very bad buy... Do it for a guy who just blew his engine on which more then $4000 were spent
