Ebay External Wastegates

[The Humjet]

For my turbo build i'm planning to go with an external gate and I've been looking at some Tial 44mm wastegates and they're not cheap enspecially when compared to the price of some chinese ebay one like obx for example. how bad can these wastegate can be?

[fiftytakedowns]

hey, I have a turbo concepts (name brand) external wastegate that is 38MM if you are interested. I'd sell it for 140 dollars. Thanks!

sorry for the thread jack, but I had an ebay eastegate, and it failed immediately.

i need a 44mm one because thats the size of the output on the manifold I have, do they make adapters to fit 38mm wastegates because that seems to be a more suitable size

If your going to go cheap get the wynton unit.

china wategates are mostly fine but never come with the right spring.
They're usually like 30psi springs.

I've heard good things about those. I have his BOV and LOVE it!

You know what einstein you always know what cheap stuff works best, the problem with most build threads is that they tend to buy quality and very expensive parts to make their turbo build work, which is great but it can get out of hand when you look back and realise that you just spent a shitload on a car you originaly paid nothing for, but I think you don't have to spent lots of $$$ to have a reasonably quick car. At the moment I'm going budget here I don't want the fastest e30 on the street infact Australian laws don't even permit young kids like me to drive a turbocharged car so cheap and discrete is what im after. Einstein you seem to know how to go about it do you have some sort of build thread I could refer to.

I can also vouch for wyntonm bits. I have one of his BOVs; works great and is quiet.

Seriously, do NOT go with a cheap wastegate. That is one item I would never cheap out on. The last thing you want is for a wastegate to stick shut, overboost and blow your motor. I stick with only Tial for my wastegates and I have never heard of a tial failing. You can find tial's 38mm pretty reasonable if you look around a bit. They do also make adapters to go from the 44's to the 38's I believe.

Tials fail too. Usually a torn diaphram. But they last a hell of a lot longer then the ebay ones. A lot of people will buy the ebay unit and then toss in a $50 tial diaphram when theirs gives out. I have a build thread but i did use all good hardware ($2600 build). I researched for a year before i bought any turbo parts to see what parts are proven to work and what is just junk. Wynton is one of the best ebay sources for quality chinese parts. He uses his designs and sells everything direct. CXracing has the best prices on intercoolers and plumbing. The quality of their plumbing is really good and it can even be stretched 1/4" with out cracking. Also comes with good couplers and t clamps. I was planning on doing the ultimate budget build this week but i've been swamped. If you are patient and always have money on hand you can find some killer deals and get your car built for peanuts. Also DSM bypass valves work in a pinch and can be had for nothing at your local pick and pull.

Yer I found the adapters they're all over ebay which is cool

I had a look at the wynton wastegates and they're going for peanuts so your saying they hold up ok for say 10-14psi of boost
the CX racing manifold isn't exactly a pretty looking thing and the wastegate port hit the steering shaft (RHD car) what are you thoughts on the obx turbo manifold adapter

If your wastegate fails and you hit 30 PSI and blow your engine, dont say I didnt worn you.

It happened to me.

It also blew 3 pistons, but I didnt know that till later.

buy my wastegate :)

You know what ill take that onboard I don't wanna be blowing any pistons usually when I buy something I opt for the more quality product anyway but for this build im trying to go budget cause sadly turbos arnt cheap, should i just go for an internal gate instead. Sorry fiftytakedowns but atm I'm in the selection stage of my build by the time i start put money down to buy bits and pieces you'll probably would've have sold your wastegate by then

Honestly, that's exactly what I did. My turbo adapter came with a provision for an external wastegate, but I blocked it off. Worked fine.
