Tial Style External Wastegates

"road racing"

Huh?

[2pee]

Seems to be missing half a dozen springs. Should be reported to ebay for gross misrepresentation too.

"road racing"

Huh?

Perhaps it's called "circuit racing" there?

We call it "road course racing" or shortened to road racing, road course, etc. Semantics

[jay-rod]

Ok makes sense.

I though you meant on the street

Does anyone know if they produced fake Synapese Synchronix gates? Anyway to decipher if one of them is a fake or not?

Those Chinese will copy anything you are willing to buy, and they do a damned good job of it these days. Sometimes it is nearly impossible to pick, such as the new Bosch 044 copies.

The price. I think mine was about $550 for 50mm

If you want to be sure you can buy direct from Synapse Engineering:

Hey all just resurrecting a zombie thread from last year to look for a bit of advice.

I have a split flange t4 manifold for an rb26 and it has provision for two 38mm v-band external wastegates.

I don't want to cheap out on the wastegate (or boost control in general) as I spent a fair bit of money building the motor itself.

So far the only reputable brand that seems to have a suitable wastegate is the TiAL.  I have seen them priced in the AUD$300's.

My questions are:

1) Are there any other reputable brands as an alternative to TiAL that do a 38mm v-band (turbosmart only seem to have flanged items)

2) who is the best priced supplier from whom to get a genuine item in Australia?  I'm a bit wary of ebay as some of the replicas look very convincing.

[KiwiRS4T]

Looks like Turbosmart do a V band:

That's a 40 mm. The Turbosmart 38 mm are 2 bolt flange.

[sneakey pete]

easier to get flanges welded onto the manifold?

[GTSBoy]

yeah.....and the functional difference between a 38 and 40mm gate is ......?

Seems to me that the 40 is no different to the 38, just has different connections.

I have the 40mm turbo smart Vband gates. They aren't that much bigger than the 38mm tials.
I might have mine for sale soon as I just bought another car with a full setup. Still brand new in a box of your looking for some

Will it be possible to fit 40mm onto the 38mm manifold flanges without any issues? I haven't used v-bands before so not really sure how they work.  Don't want to have any sealing issues.

When you say they aren't that much bigger, do you mean the physical dimensions of the thing? Do they have ports for water cooling as well?

Hey mate, not sure if the 40's will fit onto 38 flanges. I'm sure someone else here will know though.

Yes they aren't much bigger in physical size, that was the main reason I bought them. Tial prices are now through the roof so I got the 40mm turbo smarts for a better price.

[Soundboyracer]

Tial ,turbosmart and precision makes some excellent wastegates. i usually go with the type thats v band mounted than the regular two bolt setup due to ease of install.

a legit set also comes with springs.

[dorifticon]

has anyone had any experience with go fast bits?

Bit concerned the max boost pressure appears to be 22psi, am currently running 21 and the motor's been built for a lot more.

[Piggaz]

That's base boost pressure. You then use your boost controller to run more if needed.

the tail 38mm v band flange is the same as the turbo smart 40mm v band flange
