You put your trust and maybe engine into a knockoff? knockoff blow off maybe.knock off wastegate..well whatever.

 

it aint rocket science....canister with a spring, diaphragm and a valve. The diaphragm seems to be really good quality which was my main concern but to each his own. I got a ebay i/c with a knockoff BOV as well....look out!!!

 

I went with a 50mm synapse no diaphragm apparently we will see how that goes, it looks like a nice piece

 

I agree ^

I'm originally from the honda crowd... that's how i got into boost...
Now i run a t70 with a t56/LS1 setup in an S10.

Blow off valves, Wastegates, and Intercoolers are pretty fool proof....
No where have i seen anyone blow an engine and 100% blame a faulty IC, WG or BOV.

It is just a simple canister, with a spring, valve, and diaphram. Pull the knock off's apart, and pull your name brands apart... No real differance.

It's like buying walmart sneakers vs Nike's... Even those Nike's are made in China.

Will those name brand Wastegate's pay to rebuild your broken engine if you can blame the wastegate?? doubt it... it's business.

 

Tial is all i would ever run.

 

ran a Tial on the old setup. undecided on the new setup, been doing some research on the JGS's but it's a mixed review

 

same gate I have (HKS GTII)

 

turbo newb here...what exactly do the sizes mean or determine?? it seems like everyone is running a 44mm or 55mm?

 

On larger sized engines, like big blocks, etc... More air needs to be let out to maintain a low PSI.
So a 60mm or 55mm wastegate is ideal.
On a small block, like the 5.7 LS1, a 35 will do the trick...

I'm only running a single 2.5" pipe into my turbo from headers. A 35mm wastegate is in place 6 inches from the turbo flange, so i have no problems with boost creep.

Just think... smaller engine, smaller Wastegate... UNLESS you have HUGE piping. If i had 3" piping, i would run a 44mm gate.

 

thanks for the quick reply. so 35mm -44mm is ideal for 2.5 piping on a 346/347?

 

tiago runs twin jgs's on his twin 76 set up and loves them

 

correct.

By the way.. anyone know why my signature picture doesn't show up?

 

i can see it

 

Yep, works now~

 

I'm running an X02 Racing 50mm unit from Ebay. Works awesome, so far. $150.

However, my 5.3 is sacrificial, so if it pops, I could give a fvk. I guess I will be the guinea pig for knockoff ebay stuff, lol, since I could buy another 5.3 shortblock for the money I saved buying the X02 instead of a Tial....

 

Same here, I saw the video demonstration and I really liked it. Nice piece.

 

Video...?
What do you mean no diaphram?!

 

might as well ask this in the WG thread
is there any down side to a big waste gate other than it cost more ?

 

There was a demonstration on their Ebay ad. As far as no diaphragm, I'll let someone else explain it. This is the only WG I have ever handled up close so I could not point out the differences. It just looks like a big valve in there.

 

synapse uses a piston with an oring instead of a diaphragm. i just traded for one to put on my truck so I'll be seeing how they work
