Has Anyone Had Any Sucess With Chinese Wastegates ?

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

Spoken like a true salesman of expensive parts :ermm:

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.

      Actually,  just remembered there should be info in the threads (somewhere) about swapping to a manual steering rack and deleting power steering all together.

      Thinking of getting a Q50 300hp and just tuning it instead of getting the Q50 Red or 400R

      Also had a look at the Nissan JP website looks like the 400r has a slightly shorter ratio than than the regular V37 3.133 VS 2.937 which from a guy who has driven both 3.69 vs 4.11 ratios in the S15 is bugger all. Seems that the AUTO Z runs the same ratio as the 400R but can't find any info as to if its an open or LSD? More often than not the auto LSD is open

      Do not replace the power steering lines with this stuff. If it's anything like the Chase Bays stuff it will leak and be worse than stock. The reason why the reservoir is on the LH/passenger side of the car is because that's just where the reservoir was most convenient to fit. Don't overthink this stuff. The intake/cold side of the engine is pretty busy on these cars. And again, the hardpipe is designed to be a janky power steering cooler. In theory you can replace it with a real power steering cooler but that's really only for track use where boiling the fluid is a distinct possibility. Start with the low pressure lines feeding the pump from the reservoir. Make sure there isn't a bunch of junk in the reservoir filter. Be careful to not get ATF all over the engine bay. I hate dealing with ATF spills, you can clean it up and the slightest crevice will still release more oil that can still drip over time. You also want to inspect for leaks before you make a mess and can't tell what happened. Most likely you have a leak somewhere that is allowing fluid out and air in. Failing that it's allowing air in but not fluid out. Only place I can really see that happening is on the low pressure side because the pump will pull a slight vacuum to draw fluid in. Everything after the pump is high pressure or lower pressure, approaching atmospheric by the time it returns to the reservoir.

      Skid pans in/around Sydney?

      I did a skidpan night at SMSP this week, it was much cheaper than $350. But yeah, you need to slap an LSD in that thing.  I put an OS Giken in the 370Z and it's f**king MARVELOUS even compared to Nissan's viscous LSD. So you're saying it's free now that it's a housing estate? 😂

      Nah, the car seems to run exactly as it did prior, in saying this it does "seem" to be better down low, like more eager to rev, but that may be 100% placebo effect from intake noise But, I'm not worried about it at all, in the end it is a fairly low compression NA engine that has a well shrouded intake,  if it is getting hotter IAT I cannot notice anything negative performance wise from the seat of my pants thrashing it about on the street or sitting in traffic, so meh, car now now makes induction noise so I'm happy
