i bought this a few days ago and all i've been hearing about it is bad... there is no shaftplay but i'm being told that they create alot of smoke and that they wont give me the power i want. My goal is 300whp and i'm hoping i can do that with this turbo. let me hear from people that have the same one, please give me your input.

thanks

To small for 300whp

 

i used the same one not on a honda but another one of my cars, spooled great low end but topped out very fast, not enough volume go bigger.

 

what do you all think is the max power i can probably get from it?

 

first off, no particular model of turbo 'makes smoke' so whoever is telling you this i wouldent take their advice on any other car related stuff. 2nd that compressor could be any number of sizes. most common that have that style housing are the 40-45 and 50 trims. The 50 trim could make maybe 250-275 on a D series if you ran over 15psi. For 300 a 50trim To4e would be great on both a D and B series.

 

You need to take that thing apart and find out what you've got.

It could be a small T3 a large T3 or something in the middle. 300 whp on the larger T3 is very doable.

how would i know once opened? sorry new to the game.

 

2 things you need to know:

1) The A/R of the turbine housing...it's usually stamped into the casting on the hot side of the turbo (that bolts to the manifold). It's usually .36, .48, .63, or .82.

2) The trim of the compressor. You will need to remove the compressor housing by removing the 6 bolts that hold it to the center section. Once you pop the cover off, you can measure the outer diameter of the compressor wheel and the inner diameter. Once you know those 2, you can look on a chart to see what "trim" the compressor is.

A 60 trim compressor wheel coupled to a .63 a/r housing will easily make 300 whp.

That looks like .42/.48 ar t3 turbo. I had that on my setup before b18b1 and it is not candidate for 300whp.

 

will i need any new parts when putting it back togheter or just use the same things? (i.e. gaskets, seals)

how much hp were you making?

 

I found one that looks exactly like mine and it said this;

Compressor: .42 A/R, 45 trim
Turbine: .48 A/R

What would mean as far a power making capabilities?

 

i dont think 300 hp is going to happen with that.

I have the same thing 42/48, 45 trim t3 now. I'm only aiming for 250 or so and that may be a little difficult.

If you're goal is 300 hp then try to find a 60 trim. I had one one on my old LST hatch, I think it was 263 hp or 253 hp that I made with it at 10 psi.

You can't judge by looks. Many of the Garrett turbos in the T3 family look identical on the outside.

I've had many T3 turbos pass through my hands and I have never had one with a 45 trim wheel. They've all been 50 or 60 trim compressors.

Take it apart. Don't be a chicken.

Sonny

 

i separated the manifold from the turbo and i found this number inside the turbine housing is .63


Then, ilooked careful for any other numbers and seen that on this part of the turbo there was a 42

 

the only really important variable is the compresor wheel size, the rest of it is all minor comparatively. take off those bolts and measure it. you dont need any gaskets.

I get 45s all the time. 50s are more rare than 60s around here. and ya, dont be chicken!

 

first of all, i want to thank you Sonny and Bailhatch for all the help!
ok so i'm not a chicken, i opened it... i found a link and i'll let you know what i found out. Do you know a simpler way to explain the formula to determine the size. im not too god in math and the way it looks is just more confusing.

Thanks again

 

I buy those turbos all the time from the bone yard for $25.... my best time in my LS civic coupe with one at 11 psi on a FMU was 13.2 spools very quick! i did have to replace it every few months do to blowing oil seals though but that could be cuz of my shitty oil return. but since junk yard turbos are so cheap its not a bad deal

Good job.

The upper 5 maps are T3 compressor wheels. Each map tells you the outer diameter of the wheel (Excuder) and the inner diameter (Inducer). Simply compare your measurements to the ones listed to find out what trim you have.

Sonny

 

Went out and got me a 6" dial caliper and measured the diameters of the wheel and it turned out that they were the exact ones as this one:

What does that mean? Does the "S" mean something that you guys know?

I think T04S means a .70 AR compressor housing.

 

is it the same ones as these?

http://www.turbocalculator.com...1-101

Would the only difference be that mine is a .63 A/R?

On the S trim the compressor map is the same one...

 

weird, i did not expect that thing to have that wheel in it at all. looks like it could make 300. Seems to be a pretty narrow efficiency range though.

those turbos you posted have much bigger turbine wheels than what you have, I think its time to see what turbine wheel you have so pull off that housing as well and do the same measurments.

 

Are you sure you measured that thing right? It is really unlikely to have a T04B compressor wheel in that housing. If that is what you've got, you lucked out. It takes a lot of custom machine work to put a compressor wheel from one family into the housing of another.

Measuring again right now and came up with the same result... So it's a good thing having a wheel that size? How about mine having a .63 A/R and not a .84 or .96, is that going to be a problem?
