according to a PM convo ETS Tom and I had. The 50 trim is the closest to the 3076 whereas the 58 Trim is closer to Buschurs 3065.

well looks like my plans for the dyno are over since my clutch has left the building. Today while doing a 2-3 pull on the freeway it decided to give me problems. However after letting it sit for a bit it seems fine now, but I think only until I rip on it a few more times and when its hot its toast.

so I am sorry to say no real data from me till next year

waiting for tom to Pm when my 58 trim is near complete and if I have the funds . . . SMIM too. dyno #s very soon after that so hopefully early to mid september. time to get kicked of the track weeeeeeeeeeee

if you can't tell i'm really excited. Kinda feel like a little kid at christmas!!

Duby

Just thought about it . . . I'll be running the stock maf w/ stock ecu on a stock block errrrrr TOM!! what kind of power do you think I'll put down? I'm nervous as too how long my car will last with 87,000 miles no t-belt job done either_ if it blows 2.1 or 2.3 over the winter

Depending on pump or race gas power should be from 420-520+. only one way to find out how long it lasts though

That suck bro . Atleast next year you will have cams and maybe more mods .

Thats the way i felt when i orders my kit and about every supporting mods to go with the turbo.....my car was completely stock before this, so i was extremely excited .

I will be running mine with stock MAF and stock ECU and stock block too. I only have about 17k on my car though with no heavy driving. You should put down great #. I will have my numbers soon, so.......keep your eye out . So you went with a 58mm option??

Duby

Yea I plan on getting the block built, maybe the whole thing, plus some other goodies down the road.

^sounds great...2.0l built or stroker??

Duby

ams has that new 2.3 that revs out to 9500 I thought so I'd be thinking of going that route

You sir are correct. The 50 trim is more efficient than the 57 trim. Both turbos will make 400-500whp depending on fuel and boost, but the 50 trim does have a better powerband.



Here guys read the basics of turbocharger!

Q: What is a CHRA?
A: The CHRA is the center housing and rotating assembly, it houses the compressor wheel, turbine wheel, turbine shaft, bearing system and other small parts.

Q: So my compressor housing says .60 on it, does that mean i have a 60trim?
A: No, thats not true, the .60ar refers to the aspect ratio, but most know it as the size of the compressor HOUSING not the compressor wheel. you can put a 50trim, 57trim, 60trim, 60-1 and a wide range of others in a .60ar compressor housing. Just because your compressor housing says .60 doesnt mean that its a 60trim.

Q: What are the most common T4E compressor wheels?
A:
-40trim (T4E compressor wheel)
-46trim (T4E compressor wheel)
-50trim (T4E compressor wheel and a SRT favorite)
-54trim (T4E compressor wheel)
-57trim (T4E compressor wheel one of my favorites)
-60trim (T4E compressor wheel)
-60-1

Q: What are the most common compressor housings?
A:
-50ar
-60ar (T4E usually has a 3" inlet)
-70ar (T4S usually has a 4" inlet)

Q: What does T3/T4E really mean?
A: Well a T3/T4 is a hybrid of a T3 hot side and a T4 cold side. The T4E refers to a family of T4E compressor wheels that is paired with the T3 thot side (turbine side).

Q: What turbine housings are available on a T3/T4E?
A: Well there are 5 basic turbine housings, available, they are:

.36ar (very uncommon and usually too small)
.48ar
.63ar
.82ar
1.06ar

Q: What does stage 3 mean?
A: Well stage 3 is a turbonetics term for a specific turbine wheel, Garrett has a term for basically the same turbine wheel, but they call it "T31"

There are 3 basic turbonetics turbine wheels: Stage 1, 2, 3, and 5

The higher the stage wheel, the slower the turbo usually spools, for example, if you have a 50trim compressor wheel, the stage 1 turbine wheel will spool faster than the the stage 5 turbine wheel, but it will not flow as much turbine gases as a stage 5 at high RPMs.

Garrett turbos use different terminology, the stage 3 is referred to a T31 with a 76trim, the stage 5 is referred to a T350, most guys use stage 3's or T31 turbine wheels.

Q: A 60-1 says it has the same trim as a 60trim, whats the deal with that?
A: Well they do have the same trim, but the 60-1 has an additional compressor blade (7 compressor blades) instead of the standard 60trims (6 compressor blades)

Q: How do i calculate compressor wheel trim?
A: Trim is calculated by doing the following equation:

Inducer Squared, divided by Exducer Squared, then multiply the equation by 100.

IE:
If your inducer is 80mm then:
80^2 = 6400

If your exducer is 100mm then:
100^2 = 10000

6400/10000 = .64 x 100 = 64trim


If you guys have any tech questions feel free to ask

^ very good info!!!!!

Duby

those compressor maps make me nervous, especially testing out the 58trim which no one has yet. running 30-32psi on pump meth . . . getting tuned early - mid september. Tom I hope this is some good stuff, If you get your 58 on and tuned, get back to me asap with some numbers, dyno chart and feedback

boostinpsi

yea if you wanna pay 8 grand for just the shortblock. sick motor but thats ridiculous.
