Turbo for DSM, that makes full boost from 4000-8500+RPMS?

[turbotalon1g]

Can anyone find one, between years of experience, professionals, and you professional Introwebz users can anyone find me a turbo that will do as I have asked in the title.

I can accept a late start like 4500rpm and maybe a max of 8000rpms if the turbo comes up on early.

We will call full boost - 25-30psi.

Motor is a 2.3, cams will be GSC S2 grind for strokers.
Plan is to do a 2.3 to 2.4 limit revs to 8500 - 9k. The power doesn't really matter that much because most things that will flow in that region will most likely flow 550+, if i had to state a number I'd say 600 at map thru a 5 spd.

I'm more worried about the RPM as I'm limited to 3rd gear at the track.

Now, i know I should probably just get a X, because I have seen scheides to do it. Please end that talk here, also get MN to use sand instead because I couldn't drive that car in salt i would cry. (well not everyday)

I found this:
2.3, HTA3586 .82, FP3 cams.

Well what kind of power are you looking for?

ps. you have a 2.3L? Or is that the plan?

^Sorry I will update original post.

Since you don't specify what "full boost" means as far as PSI, and since you said power doesn't matter, I ran my E3 16g at "full boost" (20 psi) and it held that all the way to 8500. My GT30R was also at "full boost" at 4000 rpm as well.

[93gtpeater]

My scm is full spooled by that rpm at 29 psi. From what I saw it never lost boost at redline. But the car hasnt been on a dyno so I cant say the power doesnt drop off up top.

kevin, i'm hoping for more input on setups that make good power. KTHXBYE

Yeah, I've heard a few guys are running the 6262 in a bolt-on and getting similar results, apparently PTE has a redesigned mitsu housing.

Everything i find that spools early takes a pretty bad nose dive.

I know, I was just being facetious. Sorry you didn't get my humor. Maybe you should be a little more specific than "power doesn't really matter" for your goals.

[turbotalon1g]

^Sorry, internet humor pwnz me. :O(

But if you read the whole sentence, i said that anything that will actually flow in that RPM region will make 550+.
I guess 600whp on a dynojet thru a 5 spd.

Turn that EF1 into an EF4!

[turbotalon1g]

^ I don't believe they can because DSM turbine housings are too small!! IF not I totally would.
I'm gonna shoot for a 10.99 on this EF1 then move up me thinks.

[Murlo26]

I would look at the new PTE5862 from precision, not sure it would flow all the way to the top like you want though, but on a 2.3 or 2.4 the spool would be awesome. The 6262 is laggy though, which is why I didn't say that.

Honestly, my favorite turbo in that range, although expensive, is still the HTA3582.

That would probably do what you want with ease.

Otherwise look into the new EFR line from borg warner, also expensive but supposed to be uber spool and top end.

I am simply suggesting the ones that spool well still and make good top end, not caring about price.

[Shane@DBPerformance]

Here is a 2.4l old real GT35R .82 A/R exhaust housing. .63 might spool 500 rpms quicker. Only 20psi though.

Thanks guys, Murlo I was thinking the same thing I need to hit up jeremy with the 2.3 5857 car and see how that looked maybe.

Thanks for the graphs shane that graph of the 2.4 & GT35R looks pretty much like what I want and maybe the new tech. wheels can get a couple hundred RPMs of spool.

I'm going to keep researching this and posting graphs where I can.

[19TsiAwd90]

what about a holset hx40 in the divided t4 housing? that should spool decently on a stroker and not die off up top

[turbotalon1g]

^I'd have to ask shane again on that one, because everything I can find does not have solid results to include my own with the bolton housing.
If I were to use a holset again it would have to be in a TS housing and that would take a whole setup change and limit my turbo selection in the future.
I would need a lot of proof that TS works and from what I find 6262/3586 seem to work great in .82 T3 open housings, not that I haven't seen a few TS 35R setups work.

[19TsiAwd90]

well you can get them in t3 or t4 open or divided the cummins fourm is a great place to look i was planning on going this route with my talon

Edit: yeah i would ask shane more about the hx40, he will definetly know more than i..
also you wouldnt want to use a bolt on housing if you went with a holset.. it really chokes them down.

[turbotalon1g]

I know about holsets I have one outside and I have run one before.
Also I ran a bolton housing and it worked great fine, the problem was the internal WG.

The problem with the holset's and it DSM users are that the results are stupidly inconsistent.

Get an X. Please stop posting. KTHXBYE!

[turbotalon1g]

^lol.
Curt Brown said that I should get a 86hta.
All runs were on a 2.0, I believe this is the turbo that did 811whp sometime.
Now i do not expect to replicate this at all, but if I can get that pump gas powerband and numbers I would be happy, i think on a stroker it would be to the left 300-500RPMs. FYI that pump gas number was 29psi IIRC.

Brad's DSM82 seemed to spool pretty nicely and make great power:

I might lean towards the DSM86 with the 2.3L but who knows.




With that in mind, don't do it! Automagic. 16g/ef1. 6-bolt. Keep it as-is, rip it!
