What is everyone's thoughts on this turbo?

I'm looking to run into the low low 11s, even dip into the high tens on boost alone....trap into the 130s

then i'll probably throw a small shot of juice to push the car over the edge into the mid tens....

Will this turbo be capable? Anyone currently running a simular set up?

will be running eagle/wiseco combo, hks 272s, JMF Intake, SBR i/c, dsmlink, 1000cc inj, etc....

i'm thinking like 33psi will do it?Turbo will be run with tial 38 off the o2 housing....

I'm thinking this turbo because of the price...Can't go wrong whent hey are 749 at dejon tool...

Get the T3 version with the SP compressor cover.

That would easily hit your goals.

I prefer to stick with the mitsu manifold, becuase my wastegate set up is for off the o2 and its a mitsu o2 housing...

If your wanting to use te bolton turbine get the scm6176 its the same as the scm6152e just uses a P trim turbine wheel

according to precision's web site the largest bolt on would be the 6152e...

where did you see a 6176, last I knew it was the t3 housing that had that

Its not on there site but you can order one that way. And its a good way to help lower the backpressure of having a smaller a/r turbine

if you ordering SCM61 make sure you get the S/SP comp. housing.... stay away from TO4E comp. housing.

There are issues with compressor surge on PTE 60trim or bigger turbos using the E compressor housing.

Is it only on pte turbos.I have a t4 60trim with a to4e housing.Are you guys saying it has bad compressor surge or something.

Mine initially was a SCM6152e boosting at 25psi the surge is slightly noticeable. After it smoke for sometimes i send it for repair and change to P trim with ar .70 T4 turbine housing. During the repair i found out that the thrust bearing is not screwed to the center cartridge. Now i'm running around 29-30psi and it surge like hell....

Where did you hear that?

yeah see I asked around a little bit and a lot of people are very successful with an e cover. Seems like you shouldn't surge if you have the b.o.v. adjusted properly. But what do I know I have no personal experience with my turbo yet.

Also another question is, do you think that a .63 is ok? I plan on building a motor that can rev so I was thinking maybe the .82 a/r t3 housing would be better.

Members on here and Dejonpowerhouse. I think I still have the e-mail, I'll have to go find it.

EDIT: Nope, don't have the e-mail. I found a thread about it though.

Nothing to do with what's happening on these turbos.

My SC61 surges rather badly, and I ordered a custom T04E surge ported cover.

Some info...

Surge is the left hand boundary of the compressor map. Operation to the left of this line represents a region of flow instability. This region is characterized by mild flutter to wildly fluctuating boost and "barking" from the compressor. Continued operation within this region can lead to premature turbo failure due to heavy thrust loading.

Surge is most commonly experienced when one of two situations exist. The first and most damaging is surge under load. It can be an indication that your compressor is too large. Surge is also commonly experienced when the throttle is quickly closed after boosting. This occurs because mass flow is drastically reduced as the throttle is closed, but the turbo is still spinning and generating boost. This immediately drives the operating point to the far left of the compressor map, right into surge.

Surge will decay once the turbo speed finally slows enough to reduce the boost and move the operating point back into the stable region. This situation is commonly addressed by using a Blow-Off Valves (BOV) or bypass valve. A BOV functions to vent intake pressure to atmosphere so that the mass flow ramps down smoothly, keeping the compressor out of surge. In the case of a recirculating bypass valve, the airflow is recirculated back to the compressor inlet.

A Ported Shroud compressor (see Fig. 1) is a feature that is incorporated into the compressor housing. It functions to move the surge line further to the left (see Fig. 2) by allowing some airflow to exit the wheel through the port to keep surge from occurring. This provides additional useable range and allows a larger compressor to be used for higher flow requirements without risking running the compressor into a dangerous surge condition. The presence of the ported shroud usually has a minor negative impact on compressor efficiency.

So you are sticking with the E cover but modded to fix any surge issue that might happen? Any advantages to going with an S cover other than the surge thing?

Can you, or anyone, provide some more info on the 6176?

I had planned on purchasing a 6152 w/ a SP cover but sticking with my mitsu hotside for a few reasons. One being its a fairly new sbr mani w/ a tial 38mm wg on it, and two I don't have the extra money to throw into a t3 mani/ header and then build/buy a custom 02 housing. If I were to do that, $750 would easily turn into $1500+ for a good setup. While I know a full t3 setup would have significant gains, I just need to stay with the mitsu hotside for now.

So yeah, more info on the 6176, is it what you say it is?

You'll more than likely gain a bit of flow out of an S cover, but the problem for me is that I would need a new backplate, which means the turbo would have to come apart, which means rebalancing.

By going with a custom ported E cover, it's a direct swap.

Ah yeah I wasn't sure about the back plate. So in your opinion the flow difference wasn't worth the price of all of the work.

How much was that housing?

Nah, it wasn't worth the cost. For someone looking to max the turbo out, yea, it's worth it.

Note, too, that you can buy these with a T04S already in place.

Price for the cover was $195

yes it's just a SC61 or SCM61 with a p trim wheel rather than a T350 http://www.precisionturbo.net/turbochargers-display.php?company_id=101795&category_id=3026 any precision turbo dealer should be able to get you the 6176 with a mitsu hotside

Ok well on that website it doesn't show the 6167 as being available with a SP cover, but would it be? I'd assume so b/c the coldside specs are the same.

And what about the 6169? Looks to have the same specs all around as the 6152 but with a t04 wheel compared to the 52's t350 wheel.
