How's my port job? *PICS*

[always_broken]

It's my first time. I tried to match it to a 7cm ss gasket.


Please comment, I know it isn't perfect but any one w/experience chime in. I need the help.

2g manifold, the runner divider wasn't touched:

I cleaned up the runners a tad bit on the 2g manifold. I also wanna know if I can port this:

And I haven't messed with the wastegate flapper part yet, but it's a 14b and was wondering if I should do it...

Not bad at all.

Couple minor things. In the first pic it looks like you ported a bit of the whole there, which you want to stay completely round. Not a huge deal, but be careful to just port the inside, not extend the outter hole here.
The second pic is good. If you want you could even shave off more of that inner ring there. I wouldn't port it anymore then just making it flush with the biggest part.
Don't port what your showing in the third picture. As for the flapper hole. My experience with that is DON"T. It is way to easy to port to much and have the flapper not seal. I didn't even like upgrading the flapper. The best thing in that case is buy a bigger exhuast housing that is preported there and has a bigger flapper. When the flapper doesn't seal all the way, life sucks.

Good job porting, you got alot farther than I did... that's for sure... what tools did you use if i may ask?
I used a crappy dremel type of wheel which wore away in seconds after touching the cast iron..

looks sloppy
don't worry the first ones always are.
yes you can port the outlet of the turbine side but DO NOT go deeper than 1/2 to 3/4 inch.
just gasket match it to an evo o2 housing gasket and you will be good. so long as you have done the same to your o2 housing!
I would smooth the turbine inlet more too. really knok that step out of there. again do it to the same gasket you are porting the exhaust manifold to. go a touch smaller than the gaskets all over. the gaskets have play around the bolt holes, so if you gasket match PERFECTLY, when you bolt it up you will have a bit of gasket hanging out somewhere you dont want it to be... in the flow!

An air die grinder and a set of double cut carbide bits are a great investment.

get good and charge your friends!

 

[always_broken]

and charge your friends...


haha


I used a electric die grinder from :
http://www.edmwi.com/home/edm/search?keywords=die+grinder


7 bucks and some double cut carbide burr bits from ebay 10 bucks shipped.

I'll smooth things out tomorrow and see what kind of results I get.

 

[sd_ff22]

did you pick up some aluminum oxide shaper stones? after you do your material removal, you can do a good amount of smoothing and blending useing those stones.
keep us posted!

 

[always_broken]

No I didn't.. ^^

Thanks for that tip though, lets see if they sell em at lowe's. bb on tomorrow

 

[sd_ff22]

Oh yeah just to specify!
you can port the Outlet of the turbine housing ON THE END THAT GOES INTO THE O2 HOUSING! just thought I should clarify cause your pic showed the wheel side.

Hmm.. can you ms paint how much I can port off? Pic below

Also, is that stud to be removed or left there? Edited in pic below...

I got the same kit... the bits that come with the kit turn to dust within seconds.

I recommend the double cut carbide bits from ebay.

What about that stud in the pic?

 

[blair6389]

Just buy a port cutting tool from extremepsi.com

 

[sd_ff22]

don't remove that stud!!!
it has to be there because you can not fit a bolt inot the place that has to fit. look at your o2 sensor housing and you will understand.

 

[blcknspo0ln]

Everything looks good to me. Albeit, a bit sloppy, but we'll forgive you for that.

Couple pointers -
1. remove the lip of the inlet of the turbine housing and smooth
2. The entrance above the wastegate hole (in inlet of turbine housing) looks ok, but concentrate on limiting the 90* turn the gases have to make when exiting the wastegate hole. DO NOT port it too much, as it will crack.
3. DO NOT port the turbine outlet to . If you port it out too much, it actually decreases efficiency. That, along with the inlet, must retain a conical shape.
4. Did you port your wastegate hole? you can port it a bit, but not too much or the flapper won't seal.

Oh and definitely get a nice stone bit in there, it really smooths everything out.

Where did you see that on their site?

 

[oldman]

D- on the inlet, looks like you didn't do much there.

 

[gorf]

Definitely take the lip off of the inlet side on the turbo housing. For smoothing, they sell 1-2 inch grinding wheels with mandrel at both Lowes and Home Depot, they work great. On my wastegate I did not touch the hole but I ported out behind the flapper so it would open further. I have not had any boost creep problems so far.

 

[1512gvr4]

looks like a really uneven port, i'd say take some more time and clean it up

Looks like you need to read the forum rules about using proper punctuation and capitalization.

 

[D_Roc1320]

not bad.. ###### better than what I could have done in all honesty.

 

[romeen]

Here you can see how I took the lip off of the turbine inlet on my EVO III 16G. I also ported my compressor outlet but this is not nearly as important as working on the hot side of the turbo or even (arguably) necessary. Remember to keep all transitions as smooth as possible.

^^^^ F- for the inlet.

Point taken. Capitalization & punctuation here I come!
