A GT3582R which is the correct name for what is otherwise known as a GT35R, or GT40. The 35 refers to the GT35 Exhaust wheel, the 82, is the exducer size of the comp wheel(in this instance its the 56trim GT40 Comp wheel), and the R denotes that it is roller bearing.
Which providing that is what you are asking, plenty of people have gone down this path. Do a search for GT35R, I'm sure you will find plenty of info, as its been discussed many times.

hi guys thanks for the info, i'll search under GT35 on the forums sorry. I was being specific.
I'm yeah interested in finding out who has installed a GT3582R with either the .63 or .82 rear and results.
P.S i know i asked a simlar thread about the GT30 quite a few months back but I wanted some fresh opinions as some people had very conflicting ideas at the time.
and there was talk of manifold design. who's found the perfect manifold design for quick spool for these motors? who makes them or are they custom per car?

had a GT35R .82 AR on my built VR4 motor.. saw only 10psis at 4500rpm.. very laggy and very little useable power band.

Did you get a chance to run a .63 to see if that made a difference?

Diamonds are forever....
Every setup is different, things like cams and exhaust manifold design plays a big part of when and how much boost your going to make.......

I think this argument has been had time and time again.
My thoughts
Before you jump in and go to such a large turbo, decide if firstly you can afford the associated parts/mods to make sure it works efficiently, and secondly that you are prepared for an engine that has its power band much higher up the rpm range.
I find most people go for large turbo's due to the way they are advertised. 650hp turbo etc. It certainly wont give you that, and I'd like see someone genuinely run 600hp on the street in any 4g63 car and tell me its a nice streeter. Not about to happen.
While I believe an engine can be built to use a GT35R effectively on the street, other people do not. JSTYLE obviously had a bad experience with one, or not so much bad but didnt have the results he desired. I've never seen his setup, so cant really comment, but simple things like manifold design to play a large part in how a turbo of this size will behave, in terms of reponse and lag.
As with most things in the auto world, there are always compromises. A turbo manifold that produces great spoolup, will more than likely restrict top end power. Its one of those things where you really have to be very specific in what you want.
I will and can put money on cars with less hp being faster and more fun on the street and the track when sorted correctly. When looking at choosing a turbo, there is a wealth of info available from reputable sources, and when looking at things such as dyno graphs, its the area under the curve that makes all the difference. That is what you feel when you are in the car, not the top mark which is usually just a selling point.
Another thing to note that during my research in producing my current street evo 3 setup. I spent alot of time sifting through garbage information coming from people who either had never tried to achieve what i was after, or simply have a race car, and think what works for them will work for me.
Unfortunately coming to a forum such as this, while you may get some good info, you will always get crap. It infuriates me when people try to tell how certain parts will/wont work when they themselves have never experienced any of it. Hell only recently I witnessed a 1.3litre street engine, which reaches max hp before 9500rpm, and uses a GT35R with a 1.06 exhaust housing. This engine reaches maximum boost by 4500rpm. I also currently have a 1.3litre swift, with a GT2876R, that has max boost by 4800rpm and makes over 350hp@wheels on pump fuel. Its all in the overall design of the system. So choose your setup wisely, do the right amount of research and you will have something that you will enjoy, instead of just having dyno sheets that show a steep power curve late in the rpm, yet is slow on the street.

Well said mate.
So far from what i've done in my own research and what I've seen here, a good manifold design, large waste gate, good tuning and a GT3582R w/ .63 rear will be quite efficient for my setup. A good powercurve should be acheivable with this kind of setup however some downlow torque maybe less available. It's a compromise though.
We'll see what happens plans are always subject to change.
Thanks for your help guys, appreciate it.

Im going to be using a Garrett GT35R with .63rear on my ZR4. Will be used along with custom manifold, TiAL 38mm external, 276cams and fuel system to support it all and Wolf3d computer.. I beleive it will work fine. Wont be as good on the street as say a big16g but it isnt meant for the street so im not worried.
