I may be upping the ante soon and I'm looking for a quality turbo in the range of 450-550hp give or take.

I have every supporting mod. Just give me some ideas and your experience.

The turbo needs to be available in a Mitsubishi housing.
 
There are a lot more things to consider when picking a turbo other then maximun horsepower rating. What are you going to be using it for? Street, drag, autox, they will effect the type of turbo you pick. Here are some similar theads to get you started:

Street and the occasional strip.

I'm not concerned with ball bearing turbos. Journal is just fine.
 
I run a PTE 5031 50 trim on my daily driver 1g.

For a street turbo it is a lot of fun. At 15psi I am making 400 and once I get bigger injectors I am gonna push it to 22 to 24 psi and hope to make 450 ish or more.

The 5031 on E85 and a good efficient intercooler can make over 500 if needed.

What current size injectors are you using?

B.S. on making 400 on 15psi.
Max that 50trim at 30+psi on 1000cc's+

Crappy log as I hit the rev limiter in first and short shifted 2nd and 3rd.

Take a look at the top of 1st gear.

Boost crept to 17psi, injectors are 650's and as you see they are maxxed at 17psi.
I will be doing a rewire on the fuel pump today to get those numbers down.

Thats a 450-460hp turbo at max. Your numbers are incorrect. I'd put a E316g up against that turbo any day. :thumb:

This thing pulls a lot harder than any E316G I have ever been in personally.

What makes you think my number are not right btw?

Wow, 400whp at 15psi on a PTE 5031? Is that a 2.0L? What type of fuel? That's really impressive. I was only able to get 280whp out of my new PTE 5557 dbb billet 50 trim at 19psi on 91 octane here in Cali. And that's with Lucas English doing the tuning... what the hell did I do wrong on my setup to lose 100whp at 4psi more boost? I know once I move over to E85 and turn up the boost the turbo will stretch its legs much better, but it's not the ideal turbo for under 20psi and crappy octane.

You just haven't been in the right 16g car yet. :)

Your turbo isn't large enough to make those numbers on 15lbs. Notice this guys making 360ish at alot more boost than your running. These numbers make sense.... yours do not. I run an HX40 and don't make 400hp at 15lbs. (60 trim)


2g GSX pte5031e turbo dyno 361whp/350tq K.P. Tuning - YouTube

Go run it at the drag strip. Your MPH will tell you your no where near those levels. Not trying to flame you... just pointing out if you think your cars fast now... wait till you turn it up! That turbo isn't even in it's "happy place" at 15psi.

If you want to get semi-accurate numbers you don't test HP pulls in 1st gear. And you don't count spikes durring shifts. Do a nice 3rd gear pull from 2500 or so. :thumb:
 
I made 441whp on a DSM-housed BW s362, on 30psi and like 4 degrees of timing advance on pump gas. I liked the hell out of that turbo. It made good power on just a base tune! If you want to go a less-expensive route, I would say go with an HX40 in a BEP housing. I am running that turbo now with a BEP housing (I sold my Tim's Turbo Housing) in their .70 T3 variant. I'm expecting some 500+ numbers when all is said and done with my new setup.
 
I honestly do not know what the car is making but I have had DSM guys in my car and Evo guys in my car and they were very impressed.

I am still a 2.0 running 93 octane throwing upwards of 20-22 degrees of timing on top end.

Magnus SMIM and Delta 275's. It may not be making 400hp but 350ish may be more accurate.

And 280hp from a 50 trim at 19 psi? Something is wrong.

280WHP sounds perfectly normal to me for a load bearing dyno. (better than normal for 19psi) 50HP is a big jump. What educated thought process came up with an even 50 hp? Sounds like guess work to me... Most "DSM guys" wouldn't know 400hp if it bit them in the butt! It's natural to guesstimate higher. Who wants reality when you can have a 400 hp car instead? It's just a bite in the shorts to the few of us that do build a 400+hp car to hear all these claims.

Weigh the car and take it to the track if you want an accurate number. Do a 3rd gear pull to redline and see what link comes up with. I think you'll be surprised.

To the OP... I wouldn't suggest a 50trim for your goals. HY35 or an HX35 would work great IMO. Don't go HX40 pro with a .63 garret housing! It's a lag monster. :)

I have already done plenty of 3rd gear pulls, Link shows 38-39lb/min and is estimating 376hp.

I will do another 3rd gear pull Tomorrow when I am headed out of town and post it up here but honestly it is not going to satisfy anyone.

And yes I have been in DSM's that make over 600hp and know what the power should feel like.

On stock cams, piss water CA 91 octane, and being well below the turbo's efficiency range, I don't know that there's anything wrong - and if there was, Lucas would have been suspicious as he was doing the tuning. I think at around 20 lbs, most people would expect to see roughly 300whp on a stock engine/head DSM. Mine came close. Lucas wasn't too surprised. 50 trims and E316g's are pretty comparable at that lower boost range.

At 15psi I am making 400

Soooo which is it? You're either talking just to entertain yourself, or you're bench racing and 100% full of shit.

Not at all. Pump gas with conservative timing numbers definitely translate to 280 at the wheels at less than 20psi.

I have already done plenty of 3rd gear pulls, Link shows 38-39lb/min and is estimating 376hp.
Too many variables in Link to claim that as an accurate horsepower estimate. Judging by the compressor map for that turbo I find it hard to believe you're logging nearly 40 lb/min at 15psi, so I'm willing to bet you're lucky to make 280whp as the car sits right now.
 
I made 496WHP, 452TQ on HX-40, 28PSI pump gas.
Pump gas being 93 octane? Here in Cali we have 91 octane, and it's impossible to run 28 psi on this crap (without meth). E85 is the only way to go, but it's only available in certain areas out here - luckily it's convenient for me where I live. But it's hit and miss when you leave this area.

Hell Chris, I made 297whp on Cali 91oct with my 20g and 12-14lbs boost on STOCK injectors..

OP: I would suggest perhaps any kind of 20g or a holset. Maybe an Hx35 with a BEP housing. That package has been proven to make upwards of 500 whp!!
 
Holset hx35/40 Fpgreen or Borg warner sx200 is what i would go with
