HKS Style Wastegate... who has it?
 

I just want to know who here has the HKS Style wastegate and is using it without any problems. I really don't want to turn this into a debate and stuff like "the wastegates are crap".

Also please state if you are using the 50mm or the 40mm ones.

If you had bad experience with it, please let me know that as well.

Thanks

40mm works just perfect for me
no overboost
useing it on a HKS log manafold

I have the 50mm. Overall when you set the style one against the actual hks you cannot tell the difference by looking at them. Just to let you know the dump tube that came with the kit welded up does not fit the bolt holes. But they do give you 2 different flanges that do fit so I am in the process of cutting the dump pipe off and welding it back on one of the flanges and angling it to fit. As for performance I will let you know.

40mm
gt35r with a blitz manifold.

it would creep when i had open exhaust, but a few bends in the pipes, a resonator and a muffler is just enough to keep it under control.

get a 50... i have the real hks 40 and high and low boost are the same 1.15 bar. the only difference is which one gets there faster. i think the 40 is just too small, i'm using the hks log manny also.

oh wait, i just noticed it was hks "style". i've got the real thing, but it dosn't matter since the copies are carbon copies.

HKS Style
 

I have the 50mm, so far no problems..

I was wandering about the HKS Style ones on ebay as well. What is the difference between the 40mm and 50mm other then the size of the diaphram.

that's about it.
the 50 is a little larger physically, but they're almost identical in construction.

ok ya i have the actual HKS ones as well
oh and also 4" exhaust all the way back.. no creep.. holding 14psi for now

so none of you actually have the Ebay version ones?

I have the ebay 50mm and it opens and closes just fine. I am getting boost creep but think its manifold design.

how long have you had it for? What Boost are you running?

Has any one tryed one of these:

Looks like it may flow a little more?

what I heard from kevin was


physically they are exactly the same inside and out.. (he opened them and compared them side by side)

the only weak link in the Clone is the WG sping...

so u just buy an Original HKS spring of ur desired boost level.. and stuff that into the clone.. and BAM...u got a perfect copy...

i don't own one personally, but i've used them before. never had a problem

Well the ones that actually failed, what happend to them? Anybody on the forum actually had one fail other then the DSM guy that put a screw through a diaphram?

Ive had it for a few months now. I am trying to get it to hold spring pressure right now. If you want more info click here .

this is what i don't understand, how come some people have no creep, while others, like myself, can't seem to get rid of it if we all have the same components?

what size turbo are you running? i've got a "small" t04s with a .84 hotside. my motor is also has a street port from pettit.

the smaller the hotside, the more tendacy to creep.

I posted about one last year in the ebay turbos thread,

make a long story short- friend gets one new in box, we bolt onto manifold with t3 hybrid on his engine, wastegate jams open after about 5 hours of use. shaft was warped (checked on lathe with dial indicator) he threw it away and bought a new brand name WG end of problems.

don't know if this was an isolated problem or a common occurance, when I posted last time everybody was baggin on the turbo's and nobody really seemed interested in the wastegate.

I would suggest you buy it, try it at low boost with a conservative tune, and then slowly up the ante with your boost and tuning until you hit its max, then watch it very carefully for the first couple of weeks. if it makes it past two ~ three weeks of use it should be OK.

So yours was defect to begin with? That's not good.

So who ever posted here had a good experience with them. I can't go by the story "my friend had it and this and that" I just need to know the real facts.

Did anyone on the forum that used the Style ones (ebay versions) have one fail on him... meaning get stuck or something else that damaged the turbo or the engine?

Thanks

I've seen two 50mm HKS knock-off W/Gs work fine. My HKS 40mm works fine with T66 and Profec B. Absolutely no differences in diaphragm construction or material between knock-offs and HKS.

I have a 40mm hks style sitting in my house just havent installed and wont untill spring/summer
