sorry to hear that..but genuine will be genuine..

that's the problem of non-genuine stuffs..the QC is never up to the mark and customers will keep on having this kinda headaches..

it's difficult to answer something that isn't build by us mate.. furthermore the diaphragm isn't a universal spec thingy..it's not one size fits all.

That's nipple i think. Try to use white tape tape 9 7 it. see if it improves the situation.

I thought boost high boost (1 bar above) only need external wastegate ??
Boost 0.5bar also can use external wastegate ? what for ?:hmmmm:

The purpose is to have a more stable and reliable boost...even at low boost.. for certain engines with very big capacity..there is a huge amount of exhaust pressure running thru the manifolds towards the turbine inlet, hence there is a chance the internal wastegate flap might not be strong enough to hold the pressure.

If 1 bar above only use external wastegate, why does the TURBOSMART comes originally with 0.5bar or 1 bar spring leh.

That's the REAL problem with replicas aka copies...

They copy things without properly understanding the proper engineering aspects behind it. And to make things cheaper..they cut corners..especially on materials..

i gerenty most will leak even you dont realized it.... slower boost build up.... boost unstable.... some look big but still will creep..... some ngam size but dont know why the sound sa sa sa sa... like the valve cant keep open constant.....

alooot laaa.... buka pasang buka pasang headache la... most customer dun realize the trouble cuz bukan they are the one hold the spanar... sometimes i see also fed up... come wid replica , go other place install.....,most can open and close nicely.. but when it sits down nobody knows whether its shut tight or not.....not the spring not hard but is the seat even enough...?

came wid V clamp.... the surface even or not nobody knows.. tightened like hell still see carbon residue at few spots after few weeks of use..... aparaaaaaa....see also wanna vomit...
