Hey for anyone out there running a GT35R or similar turbo, just wondering what A/R you are running on the compressor and exhaust housing, what kind of spool times you are getting(where your boost starts to come in), and what kind of power you are putting down.

I am sorry I see nobody ever answer your question but I am having a GT35R installed in my car right now( in a month or so it should be finished)
As soon as it is done and the engine is broken in I will do some tests and tell you if you are still interested.

Go 1.06 turbine if you like to use the gears properly and want more power. Full boost by 3600 rpm.

Actually yes my turbo has a 1.00 turbine and .70 on the compressor. So it should be like cewrx7r1 is saying. I have heard the same most of the time that the 1.06 is the most used on this turbo and the one with the best characteristics.

1.06 housing with stock ports 18psi by 3800rpm

Hey dregg100 are you making 440 whp with that setup with stock ports and 18 psi?

where i can buy the 1.01 exhaust housing for the gtr35r with the t4 flange.
Cause I have find that they sell the .086 R in ATP turbo , but I can't find the 1.01 one

a-spec have the 1.01 housing dont they?

the 1.06 housing is better in my opinion.

Excellent spool and as far as the cars i have tuned make a flat power curve from just over 4000rpm to 7500-8000rpm.

1.06.... T3 or T4?

lzamboni

iTrader: (8)

They have 1.06 T4 and I think they also have the T3 on that size. Of course if you want to make power, the T4 is better and it spools fast enough.

Ok , yes in deed , depends in what are you going to use the car , I need it for circuit track use and street , meaby the smaller one can give me less turbo lag, in case I want to know where I can buy only the exhaust t4 housing for the gt3582r turbo.
cause I allready have the gt3582R.
I know that ATP have it , but I think that is quite expencive , please let me know if you know where I can buy it besides ATP turbo.

this is for the .82 one

and this is for the 1.06
http://www.atpturbo.com/Merchant2/me...egory_Code=HSG

the first one is arrownd $200 but the second one is arround the 400 , it should not be a big diference in price betwin them.

With the .82 one, of course you will have a little faster spool, but you will loose top end power. I had the stock twins but not sequential and they were giving me max boost of 15 psi at 4000 rpm. So for example with the GT35r and the 1.00 housing I have, I will get max boost around 3600 to 3800 rpm. So you see that even for the streets it is very nice and fast spooling. Of course if your max power expectations are no more than 420 whp then maybe you can stay with the .82 and you wont feel much difference.
As for where to buy the housings, I dont remember at the moment, but you can find out easily on this forum. As you said, there should not be a big difference in price.

1.06 T3 Garrett Off the shelf item.


I cannot comment on the t04 housing so please do not fire me down, but the t3 1.06 housing is single entry, so it does not restrict like everybody claims it does.
It makes the turbo spool incredibly fast and on every car i have tuned with that rear housing, power is flat 4000-7500rpm and on some of the cars even up to 8000rpm.

People should spend money on actually using the turbo properly. put cdi, water injection and run 25-27psi of boost.

i have a t3 1.06 turbine housing. 10 psi by 3k and 16 psi by 3500 rpms. it probably comes on a little sooner in 4th and 5th. you want atleast a 1.0 a/r t3 or t4. mine revs nicely to 8k+. power does start to drop off slightly at 7500rpms. it will also make you 500+whp at 22-24psi.

rexset

Yep I think that I will go with the 1.06 t4 for the gt3582R , you just convence me , cause I dfor sure I want to get more than 400whp with mi Rx7.

And now, do you know some special compressor housing that I can make the turbo upgrade? (meaby anti surge) cause mine have the standar one.

I got the GT3582 here in my hands , but mi exhaust manifold is T4 and I got the turbo with the T3 flange so , I will buy the T4 1.06 housing ,is there somebody can help me telling me the Garrett part number of that housing , cause I think that ATP sell it a litlle bit expencive. And I have xpecial price at garrett , but I have to give them the part number.

And the last question , which do you think that is the best ingectors and fuel pump setup for that turbo (1000cc primaries 1600 secondaries ,and dobble walbro in tank , or 850cc primaries and 1600 cc secondaries one walbro or....?).

Yes, with the T4 then you could make 500 whp at 25 psi but you will NEED Meth or water injection to go that high. With the T3 I dont think you can make that much power.
As for the anti-surge, as far as I have read in the forum, you dont need them in the rotary engine since it always sucks way more air than what the normal turbo can deliver. Thats why a GT35R can give you more than 650whp on an EVO but doesnt give you more than 520whp on a rotary. Our engines are way too hungry
For the injectors, the best setup is always dependent on the use and max power you are expecting to get from the car. If you are like me, trying to get around 500 whp now and expecting to get some more in the future, the best setup is 850 primaries and 1600 secondaries. With a Supra (denso) pump in-tank is enough for that power range. I spoke with some people in the forum including ErnieT that has the almost 800 whp FD and he told me that the dual in-tank setup would be overkill for that power range. Later on if you decide to go with more power, then you can upgrade to a dual in-tank.

rexset

With 400 whp at 15 psi Im more than happy , obviously I prefer make 400 whp with less Psi possible , you know what I mean..so I will go for sure for the 1.06 ratio housing. And I will use the car for a every day driving
Ok so I can use the standard secondaries (850cc) on the primaries and buy a costume rail for the secondaries with 1600cc injectors and a denso Supra fuel pump and a fuel pressure regulator and Im done. Sound very nice in deed.

And I have only to buy the 1.06 t4 exhaust housing for the Gt3582R.

do you know where I can buy it in a nice deal price , cause I think that ATP is quite expensive , just for that housing.

Well you just posted on the thread of charlies7, the guy that is selling the 1.06 T4 divided turbine housing on the forum. That is exactly what you are looking for and a good price too.
I was looking around and didnt find a better price. Maybe if you contact a-spec tuning here on the vendors forum you may get a good price.
By the way, when you get the secondary injectors and place them on the primary rail, you have to mill a little bit the primary rail to get them to fit.
I will have a set of used 1600 with their secondary rail for sale in a week if you want it. I also have an SX Performance fuel regulator with gauge.

Ok sound nice , let me know the price of the injectors and the pressure regulator how used are they.

why are you changing you injector setup?
