hey guys so i was having a little trouble finding any real good in depth looks into dump pipes for the external waste gate and i was looking for some info or opinions i should say regarding where to pipe it to, opinions on VTA and or plumbed back into the exhaust also need some thoughts on doing a EWG dump pipe out the hood just because how easy it will be. yes i do realize how ghetto it may be and how loud it may be but i cant imagine if you drive civil and dont get into boost its not gonna be loud and shooting flames all over town. but anyway just looking for some thoughts
oh and im running a t25 off an sr20 with a FM manifold and Down pipe manifold has been modified to take a tial 38mm on top of it (location was not my doing i bought it that way and got a killer deal on it.
also have a fully built forged internals engine build thread that i will be updating with this adding of the turbo soon if you want to know more

interesting i do remember reading something like that you had posted in one of the few threads i found. do you have any idea on how long it took before it cracked
the problem im having with plumbing it back in to the exhaust is i dont have access to the vast array of fabricating tools i had when this projected first went under way over a year ago so dont have much of a way to weld it up or make on so i was looking for ideas that would make it at least a fairly easy bolt on affair which im realizing is probably
any ways basically just looking for solutions and thoughts such as pros and cons which the cracking is a deffinite con but i mean if it took a while that's a fairly cheap pipe lol I could just keep replacing it

I've got a similar setup with a dumped external wastegate. BEGI cast manifold with ATP EWG turbine housing, then a 3 inch exhaust squeezed down into a stock MSM muffler. I love the setup sound wise; it sounds totally stock until the wastegate opens, then it screams like a jet taking off when you get on it.
I ran the wastegate dump down next to the downpipe and chopped it off even with the bottom of the subframe. It was easy enough to build (just a couple small bends) but I get nasty exhaust soot down the bottom of the car. I can't imagine how terrible it would be dumping that crap on the windshield squarely in front of the driver's face. Then you've got the ugly ghetto holes in the hood. That just seems like a horrible idea to me unless it's some insane build running 8's in the 1/4 and you've got a designated pit crew guy to clean your windshield after every pass.

OP Vta ewg's are too much for some people. I might be putting mine back into my exhaust just because of how loud it is. Inside the car it sounds very loud, almost to the point where I feel like a nuisance to near by homeowners.

Your wastegate opens up beside homeowners?......Rice right there.
Cops use that sound as a homing beacon.....Utefan
Clearly you need the noisemaker dude...just do it
You only live once, just don't be a douche and open it up in a residential area!
Is that an ebay 38mm Tial?
I have never owned anything Tial, but I have a 40mm Turbosmart in front of me.
One of these does not look like it like the other...and I'm not talking about the 2mm larger hole!
If that is a real Tial I can see why it was out flowed by the EFR internal gate.
Not impressed!

Ya I have been thinking about buying a vband adapter for the 2-bolt for that exact reason thirdgen
and NBfather thanks for the input on the sound I deffinatley deciding I'll get something fabricated and not go out the hood and if I do VTA I wouldn't be a douche bag like that and get in boost in residential areas. Yes it's a real tial authentic aproved did not buy it on eBay bought it from extreme psi they sell stuff for suburbs and evos and stuff .....what about yours looks different ....also worth saying that's not mounted just slapped on there with random stuff for the picture

the guy who is building the intercooler piping for me is now also suggesting a screamer pipe out the hood for the wastegate
so i have no idea what to do ...... another worry with that method would be what happens to it when it rains wont it cause a ton of issues if water gets in there ....... anyway just looking for some opinions/ pros cons. someone to play the devils advocate to all the people in my ear telling me to do it
