T40E, T40B, 60-1, or some hybrid
I've been looking at turbos recently, and I'm leaning towards a T40B because of its flow. How do I interpret the compressor maps, the different turbines on the T40B look almost the same(the V1/V2 and the H3 at least). I know people have gotten T40E's, T3/T4 hybrids, and the 60-1 models, but the T40B looks interesting to me.

I don't mind relatively slow spool up, I want to be able to use this turbo for putting lots of boost(after rebuilding the engine later), and having it be a fun street car before. What turbo is in your car? Are you gonna be in DC next week? I'm coming home to MD from college 
. I'd love to see it. To put numbers to the motor, I'd like to push close to 500HP in the end, seeing that 500 would be pushing the limits of the block heh.

I got a t3/t04 hybrid because I dont plan on going past 350whp. Plus i was more interested in faster spool and less turbo lag. I will be in MD next week, im out in KY all next week.

Think logical, dont push the limit of the block just cause you want to. You gotta be able to put it down as well.

I am going with a t4/60-1. After talking to alot of turbo guys & shops here in NY, we came to the conclusion that this turbo would be the best bang for the buck for a v6. Putting the power down will be an issue of concern no doubt. I also had the Quaife & PR mounts added last week thanx to Jeff at Maximum Tuning so this will help to get the power down we hope. We are also looking into a bit of custom work for faster spool too... maybe customer tubular header or something along those lines. Not sure if it will work but my mechanic is an expert turbo guy who has notriety all along the east coast. I'll keep everyone posted as the month goes on. Still waiting on my turbo kit...

The T04E compressor is going to be too small for this engine regardless of the boost. Even at 1 psi the the effic. will be 60% or less. Typically the rule of thumb is if it isn't better then 60%, don't do it.
Realistically to make 500 HP, as BigDogJox said, you're going to need a T04E compressor. I don't think you should change the turbine housing. A .63 Stage V would probably work out just fine.
There's two sides of the story when you turbocharge, as you already know. Even though your compressor may be big enough, that doesn't determine how fast it can actually start spooling.
If it were me, I'd use a T3/T04E .63 Stg V/60-1.
Just remember, the engine needs to be built up, you need proper fuel and timing control and driving it at lower boost levels will not be very fun. You'll have quite a bit of lag down low unless you keep the boost around 20 psi.
Hopefully that helps some.

what
Is there some sites to educate me on the principles of turbo's? I want to get to know the little details of turb"ing" so I can have a better understanding of what I want from a set up and what I can except from that set up.

Details of compressor maps and trims and all those are fairly simple but also complicated. It basically is a map of what the turbo can output and what efficiency it works at depending on what BAR (psi for us US people) you run the turbo at and what you want to expect from it. You dont want to be putting like a T3 turbo into a big V8 and overwork the turbo or according to the compressor maps push above the surge limit on top end, that will make the turbo die quicker. Then other options like what AR to get is more fine tuning it like if you want it to spool quicker but with a disadvantage of lower top end, or less spool but major top end. Things like that.

sup Dixit.. I want Turbo Now instead of SC.. hehe
HI..I want the Same set as yours on my car since its an Automatic as well..but Do i have to change the Valvebody Recali???? most likely i just want to set this for a Car show...I guess I have to call and find out about the price ??? I want to get either your set up or kev's turbo..

You are gonna have to ask Hal about all the details on how you want it. He can work out what you need to be show quality like powercoated pipes, chromed out piping if you want, polished housing. All the bling bling stuff.

Thought this might help. I have a 3.2 L SHO with a 60-1 hifi. The Yamaha and your engine are similar in a number of aspects. The car was running a t3/4 before. The boost was instant on with that combo, and while the 60-1 has a bit more lag, it is hardly noticeable, and I think actually can be helpful in moderating throttle/wheelspin. Currently the car has ran a traction limited 13.1 @ 114, and is putting down 360hp and 345 tq at the wheels. It needs some more tuning to see it's full potential, but I am confident that running a full 1.o bar will give me some serious hp. Car still gets 23 mpg on the highway running as rich as it does currently. Here is an old pic of the T3/4. Engine bay needs a little work, but she is getting there

Custom, there are no kits at this time. While there are rumored to be other turbo SHO's out there (there is a turbo-SHO powered sand rail car and a turbo-SHO powered Probe), mine is the only one I know of. The rail car is a completely different design (due to the layout and LOTS of room), and the probe is a twin turbo. Gotta love the torque

Well, that's what my company does - turbo and supercharger kits. 
The difference between a Stage I, II, II, and V is the size of the exducer on the turbine side. More or less, it allows gas to flow out of the turbine at different volumes. Important when initially building the charger assembly so the engine doesn't choke.
We've tested .48 and .63 Stage I through V on our Mitsu 3.0L and the best result came from a .48 Stage II and a .48 Stage III.
If we weren't doing a supercharger kit for this car, we'd be using a .48 Stage II.
Email me if you have any specific questions.

I dont ever see anything about the StageV stuff, I know another turbo guru told me the same thing to get the StageV .63ar. I couldnt find anything on the site. This is where I get lose on what the .ar means and then the stages. Does this apply as well to the compressor side?
