Daily how does my port job look thread + smoke from high temp anti-seize?

[Atuca]

Well to start the thread off, HEY LOOK I CAN HAZ PORT JOB!

My Evo 3 16g started creeping on me with the install of my 3 inch Megan Racing turbo back, so I got to experience my first porting job.

What do you guys think?


Than next, when putting my turbo back into the car, I used high temp anti seize on all the new oem bolts from the o2 housing to turbo, as well as exhaust mani to turbo, and o2 housing to down pipe. Is it normal for the car to smoke? I'd say it did it at least 5 mins on two occasions on the night I got it back together. It looks like it is the anti seize, but if I rev it at all, the smoke seems to billow out more. It doesn't smoke out the exhaust, just the engine compartment.

I added oil and water afte the swap, but other than that, it should be really clean since I cleaned up the turbo housing when I had it out.


Either way, looking for thoughts on the port job and the smoke, let me know, hopefully this fixes my creeping issue!

Did you port the flapper on the o2 side? My understanding is to solve creep you need to grind away enough material so the flapper can open a full 90 degrees. Other than that looks like ya got her opened up a bit

Porting looks good,port out the wastegate area so the flapper can open all the way & shim your wastegate,it (Might) cure your boost creep,helped on my setup with creep

 

[Atuca]

You guys realize the flapper only opens 30-40 degrees right? It won't open 90 degrees unless you do the Modified Wastegate Mod:

I varified by hooking up a 20 psi air through the wastegate with the turbo out of the car and watched the flapper only open the small amount. So porting the o2 housing side wouldn't change how far it can open, since it doesn't hit it anyways.

Any ideas on the smoke though?

Pretty nice port job, especially for your first time. Sorry I can't help with the smoke

 

[mattdev]

Port looks good! Looks better than mine, . And as far as the smoke goes, it could be a million things.

For example:
Did you use wd40/pb blaster/ etc. before removing the turbo? That stuff smokes alot, and smells like candy when it burns!
Also, when porting I'm sure you didn't have the cleanest hands, probly got grease everywhere.
And what did you clean it with? Anything more than water will burn off, even soap.
And lastly, yes, if you put a ton of anti-seize on there (as you should have) it will burn off.

You should use nickel anti-sieze tape thread.

I did use alot of anti seize, I can see it sizzling where the bolt protrudes through the turbo housing. I just want to be sure that some kind of smoke from my dirty hands, or anti seize or something was normal, it breaks my heart to see it smoking

But I guess it has coolant on the motor as well probably when I droped the turbo, just wanted to be sure though.

Thanks for the props, if all looks good I will have to take it for a spin today

bad news, didn't fix my creeping

The car is able to hold boost up into the 6k range though, which is 2k more than I did have, but I am still missing the 6k-7.5k.

I have hks 272s though, so the upper rpms I am still making power (supposedly since I havn't been able to rev that high yet I don't have personal experience >.<)



Guess I have to do the wastegate mod now to keep it from creeping. What are the chances a evo 3 o2 housing would fix it? Or maybe o2 dump I guess..

thoughts?

 

[Atuca]

Option 3 get meth and run higher boost.

the descions the descions...

 

[gixrman]

Had the same problem with my 16g, the problem with running higher boost is your running outside the comp. efficiency range and basiclly just pumping hot air and over spinning the turbo. I was flowing around 40lbs. and not really making all that much power. The meth kit will help but the only other known cure that I know of is the external WG o2 housing.

 

[JusMX141]

Getting the o2 dump, adding restriction to your exhaust system, or porting the wastegate hole and adding a 34mm flapper are all options.

I like the idea of spraying meth and giving the 16G hell. It doesn't matter how much hot air the turbo's blowing if you're giving it enough meth.

 

[Atuca]

I am running a ETS ultra short route, with a 4 inch core.

heat soak? What heat soak




I was REALLY trying to avoid meth, because it mean mixing, and more chances of failure, and just things that bother me. But if I HAVE to run higher boost, oh well.

Option 4: Go external wastegate and try to find a setup/exhaust manifold that will work with a bigger turbo.


By the sounds of it porting didn't look to bad so no use trying to port more? Not going to help me none is the general agreement?

meth all the way.

 

[Scoped_GST]

meth all the way indeed. just give it an m10 nozzle and spray away. mines at 30psi creeping down to 27psi from 6-7k. no matter where i set it in the 20s it spikes to 30 and then falls down. might as well just enjoy the extra powa.

this is after i ported the manifold, turbine housing, wastegate, and wastegate flapper hole a bit a couple weeks ago.

There's a huge difference between the anti seize paste bought at autozone, compared to the nickel anti seize TAPE.

 

[Ahsieh2]

meth all the way.

Heck, with enough meth you can keep your car awake for weeks at a time!

 

[kenamond]

I'd consider an O2 housing with external gate built into it. They sell them so that they'll bolt up to the E316g and DP with internal dump. It's basically an O2 housing that you bolt the external gate to. I'm not sure what options you have for the existing WG flapper, but maybe you just tack weld it in the full open position. Then you don't have the problem with the limited flapper range. You already ported the WG port, so that might do it.

 

[PieEyedPiper]

Before spending any more money I would try porting the 02 housing as well. Unless you've already done that. While some cure their creep with turbine housing porting alone, some solve it with the combined efforts of porting their o2 housing too. Just a thought.
