Is this turbo way to big?

[RJ138]

Precicions SC6169E

.70A/R 4''Inlet 3'' Outlet (Ported Shroud) -- Compressor Housing
61MM (2.416''Inducer 3.227'' Exducer) -- Compressor Wheel
Oil Cooled / 360* Thrust Bearing / Pro Race -- Cartridge
T3 .63A/R STAGE 5 -- Exhaust Housing

It would be on a T3 with nitrous, I think the turbine will be to big.

Thanks,
Ryan Johnson

thats a little large, but a TIII with a ported intake and exhaust and head and cams should be able to spool it probably by about 3500rpm, i maybe be a little off tho. Nitrous will help it

[Frank]

A SC6169E is not the specs you listed above. That turbo is huge. Its a GT35R compressor with a full T4 housing, not a T351. The specs you listed is a SC6152S which is good for our cars if it has either N2O or some good port work done to it. The reason is the T351 is larger then a T3. At a StageV wheel, it is actually somewhere in between a T3 Stage II and a full T4. I have a SC6152S sitting on my bench downstairs to go on a 2.4L.

[Speedeuphoria]

they don't even list that turbo on there site, but I'm sure they do many custom jobs
6169 is just like a 6152 except for a T04 housing and turbine wheel w/ the same dimensions as the T351 wheel
here's the link

the other thing is the compressor cover listed is way larger then the 3" inlet/2" outlet of the E and the 4" inlet/2.5" outlet of the S cover

[Frank]

The turbo specs he listed is the SC6152E with the S option you see at the bottom of the website. It is a .70 TSO4 compressor housing.


Frank

[Speedeuphoria]

It states that the compressor cover is 4" inlet/2.5"outlet on the S cover, not 3"outlet.
I am not arguing, I think some of this info is misguided. I also believe its from SRT forums because I think I stumbled on it for sale there when searching for "SC61"

[Frank]

Oh gotcha. I missed the 3" outlet part. Read too fast.


Frank

[RJ138]

Thanks guys, the turbo ended up selling to someone else. So my search continues, might just go with a holset...

[Frank]

What are your power goals and setup? Yes Holset is cheap, but its not a direct bolt on which makes it not worth it on an 8v IMHO.

[show-off]

Ryan Johnson

Has a girl ever told you it is too big????? You car won't either!!!! lol

If you are spraying it to spool it, you will be straight.

Sorry for the confusion, this is for a Spirit R/T so the Holset should bolt right up. I want to make around 400-500+ whp, on a basically stock longblock. The car has a walbro 255, +40s, afpr, Trimcal, nitrous setup, spearco intercooler, and some other things. I also plan on adding alcohol injection for any extra fueling I will need. Now all it needs is a turbo upgrade.;)

That's the very turbo I'm running on my 2.2 8V right now!

Here is a SC6152S, however the map isnt quite the same... the S means TS04 ported housing, which gets rid of that upper left dip. Even the 2.2L guys can run this turbo without much issue of surging! This is the turbo that 4sfed4 (larry jollifee) made 501whp in his stock long block Spirit R/T with just Alky!

Here is a Holset HX35, however I think it wont meet your goals because your run out of map big time.

I would suggest the SC6152S as the price is awesome. I dont think the motor will hold together if you spray. Unless you begin to spray with a good boost controller. See if you spray on turbos this big, even to encourage good down low power, you have to be carefull because the boost will shoot up very quickly. While spray down low is good, especially with these turbos, I would seriously look into getting a good boost controller so you can keep that ramp up under control. You could bypass that by going with a bigger turbine (which would be say the SC6169E or the Holset HX40), but then you loose any streetability because the turbine is too big and it wont spool worth a crap. Plus the SC6169E doesnt come with a TS04 ported housing so then you have to really worry about surge when you spray. The turbine is big enough that you wouldnt need to worry about surge under normal config because the turbine is big enough.

Frank, so in seeing how the SC61 is mapped out, and how some are using it successfully on 8V cars, and moreover since the compressor wheel is near spot on (or is it exact) to the 35R, would that make it a possible contender on an 8V? The exhaust wheel is just a big jump from the 30R to the 35R, and I'd be a bit nervous it wouldn't come on till too late... 4000 rpms seems to be where my 30R hits. Then again, my cam is way advanced, so maybe that isn't helping things.

AM

[Frank]

The 30R should be full boost by 3700rpms. The SC61 is a real GT35R wheel, so I dont think I understand your question....


Frank

[8valves]

I trying to figure out if the 35R is a feasible turbo for a high-flow 8V car. By suitable, I mean if it would come on by 4300 rpms by the very latest.

I understand the compressors are the same, it's just the exhaust side that worries me. getting a .63 T3 35R isn't hard, but the exhaust wheel is a large steup up from the 30R. Since with my combo now I don't get it till 4000 on the 30R, I'm curious as to where that would bring the 35R on at. Did you follow?

I'd like the compressor wheel saize gain to make it easier to achieve the higher boost levels. The 30R is going to peter out around 30psi from what I figure.

AM

[Frank]

I just typed up all kinds of stuff, and then I lost it. I just started really looking around, and the GT35R has a smaller turbine then the SC6152S which is rather suprising. So the GT35R can spool faster in theory. Still not as fast as a GT3076R, but still. I do know that Larry Jolliffee's Spirit R/T with Methanol had full boost by 4000rpm and 4300 rpm with meth. He had a lot of things stock. I believe Ken just got a GT35R for his car... or was going to.

I do have a new SC6152S that could be bought :) Might go with a GT35R for the 2.4L shadow or a GT40AVNT

On my 2.2 8V, below 3500rpm around 10psi is all I get. It will start to make boost lower than that. By 4000rpm it starts coming on hard and by 4800 to 5000rpm it goes ballistic. And at 5500rpm it's full tilt. I don't know if it would work good on a 2.2 8V 5 speed. Of course it seemed to work good for Larry on his T3 engine. Although, it seems to make good power at the lower boost levels before it kicks in.

[RJ138]

Where are you guys getting turbos from? A while back I asked two local shops how much a SC6152s would cost through them, one said $850 and the other said $1050. I am just curious if you have any recomended sites that I could check out.:o

I am going to stay with an internal wastegate and saw a pretty badass setup on ATP turbos website (http://www.atpturbo.com/Merchant2/merchant.mvc?Screen=PROD&Product_Code=ATP-WGT-023&Category_Code=FLS). Has anyone used one of these? I think it would make fabbing up a downpipe easier than the turbonetics setup were the downpipe flange bolts to the wastgate housing.

[Speedeuphoria]

yep $850, if you call them direct they want $1000

Talk to Terry Ryan, aka gasketmaster, he is a PT dealer....

I was thinking about one of those, but it says T3... the SC6152 is a T350 which is differen then the T31... so I dont know if it will or not.

We also build custom turbos using the same compressor/turbine wheel combinations that PT uses. Since there hasn't been much demand for these in the past we never bothered adding them to our website. If we get enough requests we may consider adding them.

That's a nice piece. Better make sure it will fit. That exhaust wheel is HUGE. I used the Turbonetics piece but cut the whole center out of it, built up part of the flange with weld so I could port it enough to totally clear the wheel, then fabbed up a 4" down pipe for it. Works great except the internal gate doesn't flow enough and I have massive boost creep. I'm controlling it with the BOV for now until I go external.

I am still trying to learn and figure some things out, when it comes time to buy the "right" turbo I will keep you mind. I just want to see all my options and figure out what all the different terms mean, its a learning process for me. Would you be able to build an SC6152S exactly if, that is what I decide to get? Would it still come with your sweet warranty?:thumb:

Yeah I like it because it has the v-band flange, I think it would make things simpler and easier. I did see some turbine housings for the GT35 turbo on ATP's website that had an internal wastegate housing that looks like it would work to, but doesnt make mating the exuast up as easy. I would go external but I dont want to break the bank getting a custom manifold made for the T3, I think Wallace might make one but I doubt its in my budget right now.

Heres a pic of the GT35 turbine housing:

Wow Chris had no idea you can do things like the SC61. Interesting.

I have as much boost as I want (wherever I have max set at, usually 24-26) by 4100 rpms on the dot. On a 5 speed 2.2 8V. This is with the straight 30R on a TU header. You should see the dyno graph- below 3K I make under 100WHP, by 4000 I'm at 360 climbing to it's peak at 6000 and holding out till 7200. :eyebrows:

That's Awesome!! Your making some darn good power! I will be willing to bet, that in a week or so I will be pushing 8000+ R's. At the very least in the high 7's. I've found something that I feel is holding me back. I just got through doing one mod yesterday, and I carried it out for a rip to see if it helped any. The boost was 15psi in first, raised to 18psi at the second gear shift. I punched it from a 15mph roll in first, gear was gone (7200+) in what felt like a second literaly. That was about 55mph or better, shifted to 2nd boost jumped to 18psi and the tires broke loose and spun to well into the 80+ mph range, they finally hooked and 7200 RPM (90+ MPH) came quick well before 1/8th of a mile!!! I'm finally starting to get somewhere with this clunker!
