T3/t4 differences really need to know

[98GST]

What are the advantages/disadvantages to different things?? Here are the things I speak of.
Compressor: T04E 50 trim; T04E 57 trim; T04E 60 trim, 60-1, 62-1
Turbine Wheel: Stage 3 or Stage 5
Turbine housing- .63 AR; .82 AR

What are the differences between these selections and what would be best set up for 1/4 mile and what is the best setup for Top end?

What are your goals for the car? You have some drag only setups there and some street setups.

I want to be running low 13s to high 12s but still be a bi-daily driver. Those are just some specs i got off of www.diamondstarmotorsports.com that have that 1775 for turbo and stuff

 

[L2RTSiAWD]

For street get the 50-trim T04E compressor side and the stage 3 wheel .63 ar turbine side.

Agreed. The T04E 50 Trim is the best of that bunch. If you want bigger than a 50 Trim I'd suggest going full TS04 or T61. But that's insane on a FWD street car with a 12 second goal. The 50 trim is all you need. I'm considering it myself among other things. I can tell people which turbos to choose but I can't seem to pick one for myself.

Actually, the T3/T4 57-trim, with Stg. 3 wheel would work well. .50 A/R on the inducer side, .48 on the exhaust.

Or, do yourself a favor, and just look over the AGP line @ www.agpturbo.com

Otherwise, you're going to need to spend a fortune to get a good manifold to run that turbo correctly (HKS or a custom), or have to buy the crappy turbonetics one.

With the HKS manifold and changing the exhaust housing to a .58 tangential/divided it's a great street turbo as well. Throw in a set of HKS 272s (among all of the other mods needed to support this turbo), and you have a nice street brawler on your hands.

Don't you guys think that is all he wants to run is high 12's that a Big 16G would work just fine?? That would save him alot of money that way also.

Yes a big16 would be fine. I just wanted to answer which of the 2 setups he posted was a street setup.

OK I would also agree with the 50 trim!

Just out of curiosity.....

Which of you have actually ran any of these turbos?

 

[BatmanGSX]

With all the compressor maps available and loads and loads of emphircal data, any informed person should know something about the T04E series turbos. Have I ran one? No. Do I know 5 people who have? At least that many.

I'm in the process of choosing a turbo now, I'd like to think it's possible to make an informed decision without actually trying the turbo first. I've done loads of research, I've asked people who know (Josh, I think you know where these people can be found, you're there too). I've studies maps for hours.

I'm no expert, of course, but this guy is looking for which one of those turbos can get his FWD into the 12s. I think the 50trim/.63 Stage 3 can. Do you disagree?

I have a 50-trim right now... and know 2 other people with then and one with a 57-trim.

What is the difference in a stage 3 and stage 5 exhaust wheel?
Where are some websites to look at maps?

 

[fast_talon]

I am running a 50 trim with an internal gate and my friend is running the same turbo with an external gate. So far I am impressed with the turbo. I just need the weather to cool down, so I can do some serious tuning. Tuning in 90+ degree weather just sucks.

 

[IPT]

I had a 50 trim. I am not sure what I am going to get this week.

 

[GRNDSM]

Supereclipse, stay way from stage 5 wheels! I do not care how much more they can flow, they are just too heavy and take too long to spool up. My 60-1 stage 5 w/.63 does not get 25psi until around 5500rpms.

And forget about lifting between shift! That slows the turbo way too much!

Stage 5 is best suited for Automatic cars running NOS.

From the original question. NEVER EVER EVER use a stg. 5 wheel in a DSM. And NEVER EVER EVER use a .82 turbine housing. Even with a stroker, these are just too big. Maybe if you are building a drag only car with a large shot of n2o, then you can play with that crap. But you should consider using the new ballistics .48 turbine housing. It kicks ass on the old ford style .48 and gives you a good responsive turbo. The 50 and 57 trim are both good wheels. The 50 puts out a little cooler air but the 57 puts out a little more air. The 50trim is a little better all around for a DSM. The 60trim IMO is ass. You have it induce a lot of lag to keep it from surging. The 60-1 is a power monster despite not having the greatest looking map. Just run a BIG FMIC.

Or Just spray the piss out of it will N2O..

 

[supereclipse]

Thanks for that just what i wanted to here.
I thought i would be to big i didnt know it was that much difference.

 

[BrnOutKing]

I'm still a little confused...

So your saying the best streetable turbo is the

T04E - 50trim with the stage 3?

but I'm also seeing the 60-1 is also a great turbo?

I guess right now I don't care about to much lag..... my S20G seems to not hit full boost till about 5200rpms now anyways.... (got a leak somewhere) or the psi goes to 20psi at like 4000rpms... but seem like the actual power kicks in until 5200rpms.

I see the $1775 - package deal.... and have been thinking about swapping up. after I get the tranny fixed.

I want at leat 350whp... on pump gas (92 oct). (stock internals - for now)

Then 400whp on pump with internals.....

Is that possible..... with this set up and still be daily driven at that power out put?

I'm hoping with race gas to be over 500+whp (with internals)
at somepoint.... is that set up capable....I don't want to upgrade again.

Also I don't do much 1/4 mile racing anymore.... (GS-T isn't worth the time - 5/6 trannies and counting with only a best of 2.3 - 60')

However I do run a lot of top end runs from 50mph starts....(some of the people I've been rolling with have 600+whp Domestics and prefer to start from a roll)

what set up should I be looking for.....

My current set up is:
HRC S20G Turbo
HKS 264/272 cams
ARP head studs
ported exhaust manifold
ported 02 housing
3" downpipe
3" theremal Exhaust
Greddy LG FMIC
Complete I/C Piping
Blitz BOV
Injen intake
K&N
RC 550 inj
SAFC
255 walboro fuel pump


Current set up has dyno'd at 322whp(20psi) on pump and 363(24psi) on race gas.

Preferably I'd love to trap the 1/4 at over 115 on pump gas... and 122+ on race gas.

Om pump gas *with* stock internals, 400 to the wheels (FWD mode) isn't that hard. Give the guys at AGP (www.agpturbo.com) a call, and they can point you towards a turbo to support this...and spool a lot quicker than 5000 rpms.

<raised hand> Not on a DSM but on an SR20DE (Pretty much identical from a turbochargers standpoint)

50 trim T04E, 76 trim stage III Turbine with .82 a/r and ball bearing center section.

Boost onset around 3500rpm, rocking hard by 4500rpm pulled right to 8000rpm like a scalded cat.

The car made 409whp and went 11.5@124mph.

I would recomend the same turbo with a .63 housing for you. A BB center section makes for a very sweet street turbo if you can do it...for $500 more.

The 50trim is the sweetest wheel for that housing.

 

[DSSA]

From experience on a DSM..that setup with the .63 housing is quite laggy. .48 is nice on the street with some loss up top. The .58 is a nice medium.

Heres a question, is there any way of knowing what are the specs of a t3/t4 turbo just by looking at it? i.e. is it written somewhere

Not really. You'll need to measure the wheels to find out exactly what you have.
