Tial Style External Wastegates

[boothy_99]

Hi Guys

Please, no flaming, I'm asking a simple question not opening a debate.

Is anyone using one of the Knock-Off style TiAL External Wastegates (Commonly available from Ebay for around $160 and can shed some light on their quality? Obviously, wont be as good as a genuine TiAL Item, but for a street setup, which doesnt get given hell it's a possibility it could be suitable if they operate properly.

How much is your motor worth? The thing I'd be worried about is a crappy cheap diaphram splitting and boost going vertical with your motor going to heaven

The other way that they have been known to fail......my mate had one that rusted the valve onto the seat. Wouldn't open and freeboosted itself to death on the first drive after being parked up in the workshop for a while.

I guess your boost cut adjustability could add a safety for that, most aftermarket ECU's (Maybe Nistune too) have adjustable boost limit?

Thats strange, how did moisture get into it? I would assume the raw materials of even a genuine one would have had a problem in that situation?

All good points though..

My mate's car was an EL Falcon on LPG. The exhaust was always a bit wetter than when it was on petrol. But you know what happens when a car is in the workshop for a while. It gets started, moved 5 metres outside and stopped. Then again, and again and again. Always running cold for a short time. Makes for a very wet exhaust. The rather crappy copy wastegate's materials rusted. Same mechanic had never seen it before on good quality gear. Was always paranoid about it afterwards though.

In what way do you think it will be superior to the stocker you have on now?

[Ben C34]

Some things are not worth going cheap on. This is one of them.

We all know external gates have superior boost control than that of a internal gates, I have a custom low mount manifold with the outlet on it for a 44mm V-Band external gate which I intend to run plumbed back into the system on my Stagea RB25DET-NEO

Hi Ben, I am the fella that came and bought your Stagea Exhaust. I dont see if this functions properly, it should be cancelled out. I mean, everyone sings praise for Kando turbos which are copies of popular items and operate well on their own with a significant reduction in price.

[Ben C34]

Ahh, we know each other!

I have personally considered buying a knock off waste gate. And decided against it.

The reality is if it stuffs up as described by GTSBOY, boost is uncontrolled. Also, if the diaphragm breaks boost will be too high.

Relying on engine management to cut power etc is not the best way.

A knockoff turbo if it breaks it won't kill the engine. I would sooner use a knock off turbo than waste gate.

[boothy_99]

I had a fake one pulled apart the other day (Atleast I think it was fake as I got it cheap, I sold the whole setup on after rebuilding the turbo anyway) and the Diaphragm material was very good quality, similar to the ducting we use in aviation bleed air plumbing (Hi temperature).

I'm more looking if someone is using one and to see their response.

E.G, Rock solid boost control, with consistent control rather than an expected cheap quality of Fluctuating boost, and inconsistent control.

I've seen knock off trust style ones jam up after the piston deformed. Mind you, this was on a 1.5L mirage with a turbo. Imagine it on a real car, shit be melting quicker lol

We don't all know that because it isn't true. See for example the Borg Warner range of internal waste gated turbos. If your budget is tight a Hypergear turbo would bolt straight on to your stock exhaust manifold. I got reasonable boost control on my IWG GCG highflowed RB25DET with a Jaycar boost controller!

Having said that for my RB30 I got a Synapse wastegate and using a Link and a Mac valve got pretty much "rock solid" boost

That is a nice boost curve, however I have the external gate outlet, so should utilise the opportunity to run one.

By the sounds, they seem pretty unreliable, seeing as no-one has chimed in with a really good result yet.

Guess I will wait for a second handy to pop up before I get turbo, or just buy new once I have bought a turbo..

Ask scotty_nm35, he usually gets stuff a little cheaper than most shops and gives you pretty good post sales support.

[scotty nm35]

I will only sell good Aussie Turbosmart gates these days. I have seen too many issues with other gate brands to recommend them, and you are only talking another $200 or so compared to the cheap knockoffs.

It isn't an item you want to cheap out on, exhaust manifold temps get pretty damn high.

Second hand is useless as you don't get a new flange for both sides.

[boostn0199]

If you dont want to buy a tial or turbosmart etc. another good option that is cheaper than the others is hypergears 50mm wastegate Ive been running one for 3years and no issues its about the 350 mark I think.

[iruvyouskyrine]

I think they use the Synapse gates, same as Kiwi

[methz]

ive been using some cheap 50mm gate for about 5yrs now no drama. but id prefer to spend $$ on a good brand one if i done it again. but in saying that, cheap gate has worked fine on low/big boost e85 etc.

[dori34]

why pay $160 for a copy? i don't see the logic.

i paid $200 delivered for a brand new genuine Tial gate with adjustable springs.

just shop around or keep scouting ebay. even check out turbosmart range

I spoke with Aaron of driftmotion over here. He sells some Supra turbo kits and they use the china gates. He said specifically NOT to use the new ones with V-bands...He said the older Greddy style 50mm and the new flanged 46mm work great. He recommended the 46mm back in the day (when I was thinking about going single on my Supra.

http://www.driftmotion.com/46MM-Wastegate-p/dm513.htm

This is the one he uses on his car.

And...Since i plan on road racing my car I honestly would just spend the money on a proven unit with a warranty...but again safeguards like boost cut could help the issue either way if things went south.
