well im almost done with my set up and im going to be running a internaly watgated t3 turbo on my d15 j spec, but im scared of geting boost creep from the stock waste gate, and i recently found a cheap 40 mm tial knock of that i want to use, but since i dont trust either one i want to use both so if one fails the other will back it up and i wont go boom couse i wanted to go cheap. My question to you is can it be done, and no dont tell me to buy the real thing im only gonna bost around 7-8 psi and i dont have the money to buy the right thing.

 

anybody know, i have never heard of any body doing this but i think it will prevent me from boost creeping

 

you could always try and find out...

 

that's what im probably going to do,since im thinking no one has ever done this and the knock off waste gate is very affordable so ill see what happens. i just need to start installing my stuff, I've had this set up in my room for around 4 months know and im too lazy to install this stuff because of the welding an taping of things.

 

You could always get a seperate dump for the internal wastegate.

 

Jordo used two wastegates on his setup to avoid boost creep.

I've seen two external wastegates used in pretty extreeme appliacations, but never an internal and external used together....

Why are you so worried about boost creep? It's not that big of a deal. You are not going to see much creep if any at only 7-8 psi, I wouldn't even worry about it.

 

why not use the internal gate, and fix the creep?

well i havent installed the turbo yet, and it isnt a new turbo its a hmt set up so im just scared the wastegate might not work and the first time i boost it will blow, its just for a safety precoution, i dont want to regret it.

 

There is no reason why you couldn't.

I think they get stuck open more than they get stuck closed.[

Haha... dude, don't waste your money trying to solve problems that aren't even problems yet.

Why are you so worried about the wastegate not working? Most stock turbo cars use internal gates and have no problems. I don't know why you are so concerned about your wastegate failing when you don't even have it on the car yet.

Besides, if you do overboost, just let off the gas. My stock d has spiked up to 14psi when I was working on my boost controller and it didn't do any harm, as long as you let off the gas when your boost gauge shoots up you should be fine.

 

you worry too damn much, the internal will be fine for those boost levels. just smooth out the wg flapper port, they get stuck open more than they get stuck closed

i know you can run two external wastegates, but i have never seen one internal and one external used before

in your case, you just need one or the other, though

 

yup. ^ i wish your pt71 was bb

I probably should have been more decisive with my words but what i meant was to have a seperate tube for the wastegate .

 

seperate tube for and internal???

 

you'll be fine with just the internal one. just use that one.
