t3 .60 ar whats it like

[Mr. Spool]

I am wondering what this turbo would feel like, I am looking for something with alittle surge to it? or would I be better with a t3/t4 with a .50ar compressor, .63 turbine. any info would be apreciated.

[DuffMan]

go with the t3/t4, it will spool up fine and have a lot more potential.

[Mr. Spool]

will it give me that surge of tourque that I am looking for, instead of the t3. thanks.

[Mr. Spool]

I am also looking for which one will give better top end power as well.

I have a T3 super 60 (.63 Turbine A/R)..
Spools up pretty quick.. starts boosting at around 2400rpm.. full boost (7psi) at 2700
Loose power up top in the RPM, but i think thats mainly from my stock exhaust.. still waiting for my buddy club exhaust.
I like it, Im planning to keep this turbo until I can afford a GT30
my ultimate goal is only 350rwhp and im aiming for responsiveness.. thats why I went with T3 instead of T3/04e.
As for the torque.. oh yeah.. you can feel it.. your passenger will feel it more though..
I dont know whenever I drive my car.. my car felt slow.. but when someone else drive it, and im sitting in the passenger seat... the car felt pretty quick.. I guess its a mental thing.

I havent drive a T3/04 ka-t before though so I cant really compare...
However I heard that with a T3, you can feel the "pull" early, while with a T3/04, you feel it "later".
It all depends on how you use the car though.. drag-race = T3/04, autoX = T3 or smaller

the .63 turbine housing is a very vessatile one. they usually spool quite quickly and still have the potential to make 300-400 whp with the correct compressor housing. The .63 turbine with a 50 trim compressor wheel will be able to get you about 350 whp. it also starts building boost very soon in the rpm band, about 2-3psi by about 2300 rpm's. go for it! I don't have one but have talked to someone with a kat with that turbo.

good luck.

Ahhhhh...

.63 A/R means jack without the wheel "stage"

A .63 Stage I T3 turbine is good for less than 300rwhp...they are smallish, with a ~1.5" outlet. Will choke the topn end considerably.

Now, a .63 Stage III will get you 350 no problem, and you'll still have spool starting at ~2900 and full boost (8-9psi) by 3200.

As for compressor..."bbandit" - Skip the 57 trim. 50 trim is very much the sh!t...

50 trim is more efficient across the board for 7-15psi KA-Ts...

I have a 57, and will buy a 50 at some point, with a coated turbine housing, etc...

I am trying to get my spool alittle latter in the rpms, my current turbo spools imediatly and I know want something that will take up to 3000 rpms to spool. and give me more top end power. will the t3/t4 with the .50 compressor give what I am looking for or should I look for something bigger.

[RBS14]

are you crazy? why on god's green earth would you want it to spool later?!?

[Bbandit]

yea the T3/T4 will give you what you want
A friend of mine has a T3/04 in his SR and he starts boosing at 3000rpm.. too laggy for my taste but hey, He ran high 12s in it

[Will fastback SE]

There are benefits to spooling later. One major one is fuel economy. It be more like your stock motor for commuting until u want to move at which point you would put your foot down and have the full thrust of the turbocharger.

[Mr. Spool]

That is what I was going for, I have been getting about 16 miles to the gallan and only 200 miles to a tank lately. Quick spool is great for auto xing, I would think, but for around town i would prefure something that I had alittle more control over the boost.

this is kinda silly, but when I was a kid my dad had a fiero that was turbo'ed. It was kinda tourquey under throttle, but when the turbo kicked in, you were thrown back in the seat hard. You didnt have huge control over the car. but it felt great, So I guesse it is a sentimental thing, as well.

So anyways sob story over, The t3/t4 with the .50 compressor, and 63 turbine should do what I am looking for? should I maybe step it up to .60 compressor and 63 turbine? Also I have heard that there are fitment issues with the t3/t4s in the ka's is this true.

[RBS14]

I'm not starting a pissing contest, but you are building a kat but are complaining about gas mileage? accept it, if you want a fast car, the gas mileage is shit, even with a well tuned engine.

as far as placement goes, it's all a factor of what manifold you want to run. different manis place the turbos in different spots. you've got some reading to do. search please.

[Mr. Spool]

thanks for the input, I have searched, I have found many different threads about log manifolds puting t3/t4s into the brake mc. I just want to know what I am infor with the t3/t4 turbos, Gas millage does not have to be bad, if you set it up right you should still get the same gas millage as with stock, exept when under boost.

[Bbandit]

If I were to go T3/04.. im gonna get T3/04e 57 trim .63 A/R turbine.
As for turbo fitment, RBS14 is right. Its all about the manifold design.
my manifold's quality is bad, however, The turbo clears the MC by like 1-2inch.
You can also make your own manifold from JGStools. be sure to place the turbo flange far from the MC.

[RBS14]

thanks for clarifying my post! I've always wondered about wheel stages, now i know.

[mellojoe]

now, i'm a turbo noob, but wouldn't you want a good wastegate, too?

If you want that kick-in-the-pants rush, then you'll want something that stays closed until the very last pound of boost is built and then pops open hard. That way, you will get that stock driving feeling until BAM the boost hits and off you go.

So, I think its more about the wastegate then about the turbo...

[RBS14]

You definately want a good wastegate, but a good turbo is more important. you can have an awesome wastegate but if you have a t88, it's not going to matter how good your wastegate is, it's not going to spool until the next millenium.

[Mr. Spool]

I am using a tial 35mm, so I think that I have that base covered, hopefully. I just ordered a t3/t4 with a .50 exhaust compressor and .60 ar. hopefully this does it.

now I just need to figure out how to get it to hook up to my current set up. any imput on doing this the fastest and best way.

[Bbandit]

whats your current setup?

[Mr. Spool]

Its an Ihi turbo with a 3 inch down pipe, on a log style manifold.

[Bbandit]

you'll prolly need to weld new flanges onto the manifold and the downpipe

[Mr. Spool]

the t3/t4 does not use the same manifold flange as the ihi? will the hot pipe that went between the ihi and the intercooler line up with the t3/t4 or should I expect to modify that as well. thanks.

[ryan hagen]

what does anyone think of a ka-det with a hks gt2530 suposedly good for 330hp. i was thinking of using that sr style bottom mount with that turbo, or maybe disco potato, but i rather go the way of the hks.
