EVO III turbo parts ?('s)

[Phaze1ne]

I find someone who is will to sell me a EVO III 16g for a decent price, and it comes with an EVO III exhaust manifold also. I have a few questions befroe I actually buy it.

1. How can I tell if this is the real thing? I've been hearing about another 16g which is a total knockoff of the EVO III. I want to buy the real thing, not a cheap knockoff, so how can I tell the difference?

2. Will the EVO mani be a direct bolt-on on a 1g head? If not, what can I do to make it fit?

TIA!

the evoIII manifold bolts right up and is better than the 2g manifold too.
not,%100 sure how to tell the difference but i've seen ones that say EVOIII on the compressor housing and have heard those are the knockoffs

If its the evo III GT that your talking about the compressor housing says "Evo III GT" or something like that. I know it says GT on it. The EVO manfiold will bolt right on to your head. Take the time to port your manifold, turbo, and 02 housing while your in there.

So there is two types of EVO III's? The EVOIII Big 16g and the EVOIII GT? What are the differences?

 

[Phaze1ne]

Also, what kind of porting should I do to the mani and the turbo?

 

[2gPressure]

you would be okay without porting the EVOIII manifold because it is already large and the turbo was built with decently correct sized openings, so you would be okay without porting them, though you could see a little less turbo lag with some porting.
One thing you would definetly need to port is the O2 housing

You want the turbo that says "TD05H" on the compressor cover.. NOT Evo III GT - that's the cheap China copy..

Are you kidding? 16g's are known to have boost creep with out porting. You can try it with out porting the turbo/manifold/02 housing but good luck. Youll end up pulling it off again and doing it right by porting it. Youll also help on spool up time. Porting is cheap and easy to do.


If your wondering where to get porting info, check out www.vfaq.com and go to DSM modification and then porting.

Here's an optional question-

I might be getting a custom turbo-back, but if I don't I might be using the EVOIII O2 housing. Is the EVOIII O2 housing also a direct bolt-on?

The 02 housing will bolt directly on. Since your vehicle profile shows NOTHING its hard to tell what you have as far as mod's. If you dont have exhaust, gauges, a boost controller, injectors, a fuel pump, a SAFC, and a logger dont bother even buying it yet. It is CRITICAL to have supporting mods when installing a bigger and better turbo. Your 14B has PLENTY of potential to start with....

 

[Phaze1ne]

The one in my profile is the one I'm selling. I have another one I just bought. Building that up to be a monster. And trust me, I'm way smarter than most of these jackasses that put in a bigger turbo with no supporting mods. I just got way too good of a deal on all three items that I couldn't pass it up. The turbo is going in next year so I have all that time too put in all the supporting mods that I need to.

Here's my list that I'm working on, add some stuff if you think I need it or give any good info that I might need to use-

Dejon Intake pipe (what size should I use for the 16g?)
Custom 2.5in turboback, maybe 3in.
Boost Controller
Greddy Type-S BOV
Walbro 190lph fuel pump and re-wired
FMIC with custom 2.5in piping. Maybe 3in.
550cc injectors
EVOIII 16g
EVOIII manifold
S-AFC
Gauges (boost, egt, oil pressure, wideband)

Anything else I need?

yes and no

the o2 housing is a direct bolt on to the turbo, but the angle of the output is diffrent so it will require some adaptation to the DP unless you buy one already flanged and angled for it.

TURBODSM: true, but it is also well documented in numerous threads here and elsewhere that if you are going to run 20+ psi you shouldn't port since the flapper will blow open and the "creep"' is only to about 20 psi. Big problem on the CLONE GTs since they have big flappers and castin porting.

This is very true. He hasnt given any details about what he was plannin on doing as far as the set up, psi, hell he didnt even show supporting mod's. Good point and i will include what you said next time this topic comes up.. AKA tomorrow probably


For the 02 housing, i cut 2 slits so it would slip on and used washers and the nuts to tighten it down on my stock downpipe when i had it. It does come off at an angle like said but with a good cut off wheel you will be fine.


AS FAR AS YOUR SET UP,

Id add a logger to use to set up your SAFC, a clutch, and possibly a flywheel if your a big spender.

I put some stuff in my car's profile for you guys. Just a little somthing so you can get the jist of what I want to do.

1)porting the manifold won't help control boost creep.

2)porting the turbo MAY help if you do it right.

3)2gpressure did recommended porting the o2, which btw if done wrong *apparently* makes the creep worse.

but otherwise good advice. I just needed to add those comments to straighten out any misconceptions that may arise from your post.

I've never seen data that shows that porting turbo components helps with power or lag.

My 16G isn't ported at all. Neither is my manifold. I don't get boost creep in the summer. In the winter, I get a little creep. And it seems to do "ok" for power and doesn't lag at all.

 

[drag97GSX]

I got all my turbo components from SBR and they were all ported...current mods ON CAR are in profile. My turbo creeped regularly to 25-27 psi. Needless to say i would hit fuel cut and scare the piss outta myself. I got the flapper mod and all on my turbo. I finally had to pull the turbo outta the car and remove a ton of material above the WG passage. This way some of the airflow hit the bottom of the WG passage and helped to route it to the WG itself. After re-install, never crept to anything above 17.5 or so psi. Keep in mind that i have the boost set to around 15-16 psi (because of the factory fuel system). I found the thread on here that showed how to do the porting/material removal. Can't find the link as this was last winter i saw it...sorry. Hope that helps anybody who reads this.

 

[Phaze1ne]

Well, I was curious about the knockoff situation, even though it said TDO5H on the compressor cover, so I sent the pics to SBR. They told me it was not the EVOIII, but either a oldschool Big 16g or a small 16g, but couldn't really make out the PN's on the compressor cover. I sent them one more email to clarify on it, but this sucks that it could not be the real thing. $600 for the so-called EVOIII turbo, manifold, and O2 housing is pretty tempting, but I want an actual EVOIII.

Ive read a quite a few posts speaking of this. As of right now the "search" isnt working so i can bring up any threads at the moment. I'll get back to the post. Congrads on the good time w/the 16g as well.

 

[ShapeGSX]

Unfortunately, "speaking" isn't necessarily positive proof that porting helps anything. We need datalogs or dyno plots

Question, why don't you hear about turbine housing porting on other cars, or on Garrett turbine housings on DSMs?

Sorry to be honest i dont follow any other cars really.

Heres a full write up on boost creep w/a 16g and how porting solved that. I found it on the top of my first search. Searching is how ive found the info i was talking about before. Porting solved the creep on my B16g.

Yes, porting can definitely help with boost creep. I don't have a problem with that concept.

Whats the concept? Is it that it helps on a spool up a tad?

i bought the evolll gt ported turbo from machvmotorsports.com and it says evo lll gt is that a real evo lll gt turbo or not
