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

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.

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

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.

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

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.

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

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.

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

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.

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

^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.

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

Turn that EF1 into an EF4!

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

^ 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.

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

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.

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

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.

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

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

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

^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.

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

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.

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

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.

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

Get an X. Please stop posting. KTHXBYE!

^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!

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

Your pics don't work. Yes, an 86mm hta wheel...that turbo is legit :) I think it'll be laggier than you want though.

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

haha my graphs made in this thread twice without me :D

Looking back I loved my 3065 and if I get another dsm I'll look for something around the same size. From what I can remember on the street it hit 30psi by like 4.5k and it didn't hold super high (38) all the way to readline but held 31/32 just fine. I've seen them go for kind of cheaper lately and seems like a decent fit.

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

If I were willing to put decent money into a setup I would do something like Brad's old turbo setup, I think it would be an awesome street/road race setup with a 2.3/2.4l.

I don't know much about the HX40 stuff. I don't get a huge amount of cars in with them and I don't build cars using junkyard turbos. New with a reasonable housing they don't seem all that cheap. The Holset stuff mostly seems to be popular with people on Tuner or the DSMLink forums, I don't see them used much on other kinds of cars or by people who aren't on those forums. The cars I have had in with them had not done any of the magic things that people claim about them online for me, typical spool and power that you would exact for that size mm wheel.

Spool up and power output of a turbo are GREATLY effected by other things on the car though. A 16G is always going to spool good unless the wastegate is stuck partially open or you have some huge leak. Something that might make a 16G spool 200 rpms slower on one car over another and barely noticable might turn into 600 rpms on a big turbo. Curt Brown's stuff always performs so well because he puts 200% effort into the little details that add up(not talking about powder coating your valve cover, shiny stuff everywhere and matching hoses) and he will on occasion run things past the edge.

Years ago when the Mutt turbo finally blew up on our hacked together hand me down parts 1G I put a basic SC61 T3 4-bolt .63 Garrett housing. It made something like 440awhp with the turbo going all out, boost controller cranked all the way up. Power seemed okay but nothing that great, car was decently fast. I didn't think too much of it, the motor wasn't in the best shape and most of the parts on the car weren't the greatest. Later on, upgraded and cleaned up a few things and it was making in the 480s, car was trapping 133mph with my wife driving it. At that point I thought the turbo was just maxed, I knew the comp wheel could do more, but I though the exhaust side was choking it. I considered going to the better PTE 5-bolt exhaust housing, since it wouldn't require buying a whole new turbo, I didn't want to goto a .82 though, because the car was already way too laggy into 2nd gear after a launch and with stock motor/stock valvetrain I didn't want to rev it too the moon. I though about getting the 35R exhaust wheel like Momin and a few other guys had on their special SC61s or the 62 exhaust wheel, but seemed like too much cost for potentially small gains. Then the 6262 came out and I wanted that. Never ended up selling the SC61 or changing anything on it and instead fixed a few things and moving the car more towards a drag only car in a mad dash to try to make a race, since we didn't ever drive the car anymore. It ended up making almost 550awhp before the trans broke, but the turbo still wasn't maxed out at that point. Happy I didn't spend a bunch of money and goto a 6262 or 6765 and only pick up 20whp because other parts on the car were killing it or happen to switch turbos and make some other changes at the same time and think the new turbo gained 100whp or whatever on it's own.

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

Scheides, I'll try and fix those links.
CB said DSM86 is turbo he considers has good street manners, and a T3 not so much.

A 3065 does sound good, but it didn't sound like the upgrade would be worth it. The 3065 on a 2.0 sounds sick, and I have to agree with shane on a road race/street car the TQ would be killer, but wouldn't it get choked out up top, it looked to fall pretty decent on brad's setup, but I know that was losing boost too.

Does anyone have dynographs for SPNSALL4 aka Jeremy on here? He was at the last dyno day, i believe he just sold his car to someone in duluth. That was a 2.3, 5857 bolton I believe and I think shane tuned it to 30psi before they ran out of fuel and then just sprayed it.

Scheides, I'm gonna try and run a 10.9999 on my setup before I ditch it, I'm just hoping this motor will hold up to it.

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

This.

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

Yip, it's in the dyno day thread. He made 500whp @ MAP and 570 w/spray.

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

Yea I don't think I would do the hta upgrade again, didn't seem worth it unless you bought a used one with the upgrade already.

Boost/power dropped a little bit at the end but you can see it spiked to 38 or so and leveled off. That was the highest we ever had it spiked and if we kept it at 30 it would have a super flat boost curve. It also only had a .9 bar spring in the wastegate too. Maybe if it had a stronger spring it could of held more boost up top and made more power. We never really got it back on the dyno before it got parted out.

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

Brad's with the HTA upgrade made the same exact power at 30psi as it did with the original FP3065 wheel.

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

We're talking about your automagic here, aren't we? You're going to want a little more airflow to spool that turbo on the line vs a 5-speed, so I'd seriously consider a 2.4 in addition to your turbo upgrade. You just can't go wrong with the bigger motors unless you need 10k through the traps.
