Questions for Justin...

[stevecbr929]

I don't see anything at all on the center cartridge either. He said he bought it new at ATP turbo & it's a GT28RS - I just can't find anything specific to this exact turbo on their site. A ton of variations, but not this one so I don't know what to order. The measurements I took may not be accurate because the wheel looks like its missing some meat on it. Thanks again for getting back to me.

 

[JusMX141]

All T28's have a 60mm exducer I believe, but there are variations on the inducer spec....so without a firm spec on the inducer, you could end up with the wrong wheel. Unfortunately yours appears pretty hosed, so that could be rough to figure out. If there's even one inducer tip that isn't damaged, just measure from the center of the shaft bore to the one good inducer tip, then multiply by two.

A standard GT28RS compressor will be 46.5mm/60mm.

 

[stevecbr929]

So if all the inducer tips are damaged (yup), what do u suggest? I tried to find the least damaged to get a measurement, but he managed to have every blade on the thing hit more than a few times. I've seen some vendors offer wheels & compressor housings as an "upgrade" but I'm not sure what I would be upgrading from. Would that be a safer plan do you think?

I'm running a MHI E316G now & am pretty happy with it but I've always wanted to try a ball bearing setup & now all I need is a O2 housing & a compressor wheel & I'm rolling but I honestly have no idea what I'd be gaining with this setup. Goal is about 350whp on our crap 91oct CA fuel. Would this setup make this a possibility you think? I also got a tubular manifold & a 38mm Tial WG with a 1 bar spring.

 

[JusMX141]

You realize this will be a downgrade from a 48.2mm/68mm Evo III 16G, correct?

 

[stevecbr929]

That's what I'm tryjng to figure out. That really sucks. It doesn't flow as well as my 16g? Is there a way to "upgrade" it with a new compressor housing & wheel?

 

[JusMX141]

You can put the biggest compressor on you can find, you'll still be stuck with a turbine wheel that is smaller than a TD05H. Do this and be ready for unnecessary lag and incurable compressor surge.

Or you could forget about it altogether and buy a 30R instead.

 

[stevecbr929]

So sell this thing before I put any money into it? Damn - that sucks. The wheel looked almost identical to my 16g (compressor), but I didn't want to pull turbine out because I obviously don't know about these things. Bummer. Thanks though - you just saved me some money & I don't know how many hours trying to get this dialed in.

 

[JusMX141]

You can't remove the turbine from a GT Garrett- it's pressed into the bearing cartridge. A 16G compressor will never work- different spec, different shaft bore.

 

[stevecbr929]

I wasn't saying I wanted to try it, just trying to get some comparison. I'm fairly familiar with MHI turbos - I've rebuilt quite a few of them. All I know about the Garrett is the one that came with my car is s#^t & that a GT30/35 is what my turbo wants to be when it grows up.

 

[stevecbr929]

Thanks again for getting back to me - not the answer I wanted but at least I know not to put any more effort into this thing except to sell it.

 

[JusMX141]

Toss it on eBay- some Nissan guy will likely pay more than it's worth because of that Disco Potato car that was in some magazine 10 years ago.

Honestly the evo 3 16g if thats what it is will make 400awhp pretty easily with a set of cams and a intake manifold with good supporting mods. The highest dyno is 499awhp by curt brown but 400-430seems to be more common for people that aren't gods.

Going to rebuild my H1C and was wondering a place to pick up good rebuild kits. Ive looked at the e-bay ones already and also found this web site.
BAE Racing Components

I am also wondering if I install a new compressor if the turbo would need to be rebalanced as an assembly. The site list the compressor as prebalanced.

Thanks

400whp from an Evo III 16G isn't in the realm of realistic for the general population. I hate seeing guys recommending the Evo III 16G as an "easy" 400hp turbo...that's a total lie.

BAE is all Chinese parts. I've used a couple of their CHRA's in the past for guys who had turbos that were completely destroyed and needed to get back up and running on a budget....just beware that you're getting Chinese parts, and you're not likely to get the correct parts the first time. Their customer service is horrible, too.

 

[pos4g63]

Ok thanks and any sites you know where I can pick up a good rebuild kit?

That is not a lie. If your competent it isn't hard but varying dynos and conditions could make it more or less true. 400whp on a dynojet isn't hard with the correct supporting mods and good tune. I made 335whp with just a couple of bolt ons, 21 psi, 93 octane, tuning with the original maft on 720cc injectors back in 2004. I could have gotten more with dsmlink because the original maft on that big of injectors made wide swings with the smallest changes. Add a set of cams,dsmlink, and intake manifold and I have made around 400whp without sweating much.

So where should we get rebuild kits? Im also going to rebuild my h1c, I was going to purchase the kit from gpopshop for 89$. But if there's a cheaper kit please let me know.

 

[JusMX141]

Sounds like they have a legit parts kit- the Genuine kit #4027309 would run around $95 from a Cummins Power dealer.

Justin,I just bought an HX40G,It has 8 blades and has a T4 flange.I've been looking for specs but i haven't found anything.Did i make a good buy?

Here are the pics:

It's an 8-blade HX40- specs are everywhere on this site.

I don't know what you paid, so I don't know if it's a good deal or not. If you paid $150 it was a great deal, $300 would be average, $500 would be too much.

Evo3 16g has made 499hp. And is rated at 42-44 lbs/min. I wouldn't call it super easy, but its not super hard either. Yes it does start to blow hot air, but that's what big intercoolers, meth, and E85 are for.

 

[JusMX141]

It is a lie and your full of shit I have been building these cars since you were in diapers.I have taken a 16g to the max with more than bolt ons and at that hp you start to blow hot air and surge. I recomend you keep you mouth shut and not pic a fight with someone who rebuilds turbos for a living. Good old tunners full of little kids and dip shits go paint your car green and put stickers on it with a body kit o wate you prob have all that shit

Please don't start a flame war in this thread- that is not what it is intended for.

If you feel compelled to tell someone they're retarded for something they've posted here (including myself), do so by sending them a PM and not commenting in the public eye of the tech forums.

Evo3 16g has made 499hp. And is rated at 42-44 lbs/min. I wouldn't call it super easy, but its not super hard either. Yes it does start to blow hot air, but that's what big intercoolers, meth, and E85 are for.

These numbers have been produced on ONE car running around 13:1 compression, Alcohol-based fuel (E85/E98), a 4-speed converted manual transmission, ceramic wheel bearings, and alot of other one-off's. There are thousands of people running 16G's; the percentage of people above 400AWHP is likely less than 1%.


One of my close friends that is local did do 475FWHP/460TQ on a 6b 2.0L w/ 9:1 Ross/stock 6b rods, with a host of mods on a 2.5" exhaust. Big SMIM, FMIC, 272/272 cams, 255HP w/1000's and to M10 nozzles with 100% Methanol injection on 35psi with a ported Evo 3 16G.

Again, it is still quite a bit of work to put down over 400AWHP on one of these turbos, but it is possible and people have done it maxing out the turbo.

If your goals are for 400+AWHP, I would personally recommend a different turbocharger, such as a 50-trim (PTE SCM5031E) or Garrett GT3071R or Borg Warner S259 or Holset HX-35. They are all way more efficient at these power levels and boost levels at/above 20psi.


Though 16G's are nice little turbos, they are really ideal below 400AWHP and better suited for the 300AWHP range for durability/reliability. If you want to go above 400AWHP, then expect to be popping turbos in a shorter period of time. As well, these turbos (16G's) have dramatically increased in price from Mitsubishi and are being phased out on a production level; you are better off going with one of the other options I mentioned for a more cost effective turbo and better suited above 400AWHP.



As well, this thread is not meant to become a flame war, so stop the harrassment or flaming right now. There is no need for it.

 

[woooop]

JusMX141 so sorry to make comments like I did in your thred I am sorry, But I am so sick of these kids who think thay know everythng when I have done what thay may have and a hell of alot more. Sorry to you again I am I respect you wont happen again.

Thanks Justin,Also can i ditch the T4 Housing and put a regular HX40 T3 housing on it?
