I'd steer clear man.

Some Chinese parts are okay, like downpipes and whatnot, but I wouldn't put my faith in something mechanical that could fail easily and trash your engine.

Just my point of view.

ive been using one for over 2 years now no problem. holds what ever boost i want it to (14psi and up). Just lap the valve into the seat to give it a decent seal and have had no dramas

the jjr ones look like a straight copy of the HKS units, I looked at 'em, but found a s/h HKS unit that I rebuilt - it was a bit more expensive than a chinese knock off, but it was worth it [and it was way cheaper than a new HKS one].

Tial and such aren't that expensive anyway, your only saving a $100-200 total.

You may get a result, but its consistency you want.

CHEAP-FAST-RELIABLE <- you can only have 2.

If its cheap, might go fast but wont be reliable.

If is fast and reliable, it wont be cheap

so on

I also run 50mm HKS Copy chinese gate from the states and it works perfect. 14psi spring with boost controller i run 20psi no creep constant strong boost to redline.. thats been on nearly a year now without a drama.Its not rocket science in design seriousily.

I had a faulty one on a SR20 running a T70. one of the grub screws that hold the valve into the diaphram hat fell out and was leaking manifold pressure like an internal bleed valve. The result was the first time I held the car on full load the boost short past 25lb. It was very exciting for about 1 second till luckily a hose blew off and it save it all from certain death.

Granted putting the grub screw back in properly did solve the problem and it was able to regulate to 20lb with a 38mm gate just fine, but still Id never buy one again.

Get a turbosmart ultra gate or something Jap brand named and you dont have to worry about dodgy assembly quality.

* yep cheap gates are the best.....

* Only for apllications where overboosting, stuck bypass valves and burst/split diaphragms are needed. In fact they are perfect for those wishing to let thier engine expire prematurely.

please dont bring them anywhere near me (unless they are fully sorted) as the amount of times ive had to send customers home to repair / replace dodge chinese wastegates is unbelievable.

A wastegate is a very simple device, it's only a matter of time before the "chinese" develop one with the proper materials. That's said I wouldn't run one of those "chinese" gates just yet.

I run a Synapse 50mm gate which doesn't have a traditional diaphragm design and has built in boost settings. Oh yeah.. it's made in China :D

I dunno it seems kinda silly to cut corners there when a shitty one could potentially wreck a $3000+ engine build. I'd be cutting corners more on say the intercooler and exhaust than something which is regulating boost pressure.

      Nah, they'll do it without a receipt, tell em roughly when it was, that it was cash, youll likely only get store credit, but that gets you some dollars towards the newer better shovel, or other item you need/want later.   Still take it back and have a crack at returning it.

      Nah. Was just wondering if you were having a small stroke or if there was some slur/gaf/inside joke that I wasn't aware of.

      That was a fark up, it's Salamanca Place I was thinking of. And now I'm curious as to what potential slur/gaf I have caused with Salamander Road, ha ha!

      Actually everyone on the roads was really well behaved. The only person that did any minor tailgating was a local hoon in a Turbo Focus. Unfortunately we weren't going the same way so there was no grand initial D touge battle. Lots of people pulled over and let me through. The amount of "Hey man nice car, omg skyline, nice 34 man woo" was suprising. Like really suprising. Like almost annoying. My partner was obviously surprised, she'd never seen anyone in the real world point out the car/like the car/want to chat about the car before, so to have like 3 people per day mention it was notable, I could finally say SEE? SOMEONE THINKS THEY'RE COOL. Everyone was also pretty suprised about the weather. Every day was dry and about ~13-14C. Mount Wellington had a sign that said they close the gates at 9pm and I was heading up there at about ~7:30. It was VERY apparent that conditions were getting significantly worse by the minute on the way up and down. The road on the mountain was terrible though, it's no driving road. I have various suspension related questions now. Luckily it was only about 20 minutes from where we were staying to the top of the mountain as said Google maps. We only had the 2 nights in Hobart. We went to the Farm Gate Market though which was really good - And went down to the Hastings Thermal springs/caves down there during the day. I'd definitely be up for going back again, so luckily there's a few more sights yet to see. Didn't get to do the west coast/queenstown/cradle mountain so this was supposed to be a 'scouting' trip anyway of sorts if I were to one day do/take part in/organize a more car-focused trip. As for the boat, it wasn't bad. Well it was bad, but not in the way you're thinking. We did the night trip which leaves at 6:45 (though you have to be there ~2 hours earlier) and arrives the next morning at about 6am. There is nothing to do on the ship. If you plan accordingly and bring a book/tablet/show to watch/charger you can just chill out, take some Travacalm and just sleep through it. The food there is an extremely basic buffet that costs $32 a plate, or $14 for a $3 pizza. The way back we had a travel kettle and a few different types of cup noodles and made our own tea/coffee in the room. This was a far superior way to do it. At the very least book one of the rooms with beds. I guess as we were in the off season we didn't have room mates. You get an option for rooms with 4 beds (2x bunks) or a room with just the two bottom beds. There's also some option for a deluxe queen bed but it's much pricer. We've been on sleeper trains in Asia before so we figured this is similar (and it was)

      Was that deliberate?
