To4R feed back/advise

[FastRthenU]

Now Iam looking at a garrett t3/t04r but I cant find to much feed back with these on a 4g63. I was thinking about using a .82ar with a stage three wheel, or a .63 with a stage 5 wheel. Im just wonding about spooll characteristics, and what kind of power it should make with these selections.

So you can get a idea of what the setup is. 2.0L, 9:1 comp, hks 272's, alot of head work, and I think thats enough to give you an Idea of what its going on to. Im basically looking for 650 whp tops, full spool around 4500-5000, will see very little street and alot of drag racing.

Sounds similar to my setup, what EMS you running?

I'm on a PT67 .58 a/r P trim with T04S cover, making 15lbs by 4700, 28lbs shortly thereafter

I have never heard of anyone using an .82ar on a 4g63, I say go with the .63 and stage5. What compressor wheel is in the t04r? I know it is a turbo often used for single turbo Supra's so Im guessing its huge (<67mm). You plan on using nitrous?

I believe 90GSX (Eric Gash) is running a T70 T04r I believe with an .81 GTQ t4 hotside. I saw it in the shop. He's on the spray though. With a T04r cover on my turbo, Precision said another 500 or so rpm spool time.

If you're going with that size turbo, T04, none of that T3/T4 sissy stuff

There are some out there and actually quite a few at least in my vicinity.

 

[FastRthenU]

there are a lot of people running .82ar's. Does anyone know what the spool times are going to be with these set-ups? I thought about going t4 foot print, but for right now the t3 is ok. Im also not planning one spraying

 

[myblack98gst]

here is a car using a semi-similiar turbo

check that out it is close to what your asking

 

[FastRthenU]

Anyone else?

If you still can, go with a T4 .68 a/r housing. I have a .82 T3 a/r P-trim wheel on a 67mm (same as your To4R) compressor and it is a tad bit laggier than I had hoped for. Full 31 psi is at 5700 rpms on my 2.4. I've seen a T66/Ptrim T3 .82 a/r do 31 psi at 5700 also on a 2.3L. I know there are a few guys running the 67mm's on their 2.0's and they seem to be spooling about the same as myself. A friend has a 67mm/Ptrim .68 a/r on his 2.4 also and gets full boost about 400 rpms faster than I do. That leads me to believe the T3 .82 is either that much bigger than the T4 .68 a/r or something elseout of whack on my car and the other car with the Ptrim .82 T3 hotsides.

As for getting full boost from 4500-5000 rpms and being able to make 650 whp, good luck without nitrous and with a 2.0L.

On a 2.3 or 2.4, with my turbo as stated above, that would be MORE than achievable. On my 2.0, spool is around 5500, and 650 is within reach no spray.

What compressor wheel is in the t04r?

T04S 76 trim: 2.920" Inducer 2.542" Exducer
T04S 69 trim: 2.920" Inducer 2.420" Exducer
P-Trim 76 trim: 2.920" Inducer 2.542" Exducer
P-Trim 69 trim: 2.920" Inducer 2.420" Exducer
Q Trim 70 trim: 3.110" Inducer 2.695" Exducer - this may now be called GTQ
R Trim 79 trim: 3.200" Inducer 2.850" Exducer - may be called GTR
S Trim 85 trim: 3.200" Inducer 2.960" Exducer - may be called GTS

It has been recommended not to go larger than a P trim wheel on a 2.4 if you want to retain any "enjoyable daily driving".

Those are turbine sizes, not compressor. I wouldn't go larger than a P trim unless you're an all out drag car on the spray. a .58 or .68 a/r if you feel compelled t4 p trim will suit those looking for tons of power off the bottle.
