Need advise/guide on acuator or ext wastegate for 612ATT

[kanan]

Hi guys, I'm in the middle of changing to TT engine from the original troublesome engine/GB for my perdana V6. I don't know am I solving the original problem or just created a new ones with the new engine replaced. I hope not. Everything else about the replacement engine was fine for me except the 2 pcs actuator that stick to each of the T025 turbine.

Picture as shown above. I tried to move it with my bare hand but they hardly move. Actually I have been searching/asking around ZTH about the possibility of changing the actuator to external wastegate. Lots of views saying it's rather a nightmare to fit the ext wastegate for the back turbine near the firewall. no space . Fitting 2 pcs external wastegate was my first choice. If you had done this on TT engine please share here about what brand/size and where to do the job. Because this is actually what I wanted to do.

I still have strong feeling that I need to change the actuator either to ext wastegate or to the same one but new ones. I can't afford to see my engine kebaboom on the first week after engine conversion. Further more i'm tend to have a stable boost system for years. Finding out that ext wastegate is hard to fit, I'm now going for actuator. Due to my lack of knowledge, i appreciate if you can share what brand and where to do the job/buy that thing. I heard lot of HKS actuator but with higher spring rate. Can you exactly tell a place i can go and have a look.I would like to have 0.5 bar spring rate if possible.It's enough for my daily driving. I'm looking for a good workmanship shop.

thanks very much!!

i dunno if theres space to put WG but then Malaysia boleh ... i think if u have clearance issues just go get actuators from other turbos ... such as those from RHF4 (cut and weld)... or this ... Turbo actuator 1.5 bar universal - Accessories & Parts for sale Kelantan - Mudah.my

if WG i think u would need 2 of then ... :) plus stock spring usually comes at 0.7bar ... u might have to buy 0.5bar springs at Tong or sumwhere else ... :)

Happy Modding ...

It's hard to find actuator that can be used. Only left with JASMA . but the price justifies the quality..

JASMA is a Malaysian brand. In actual fact, JASMA is a council in Japan on the emission approval for exhaust. Coincidently, a malaysian vendor likes the name and established his own brand call JASMA.

So far, the smallest wastegate is TIAL MVS. Please refer to the catalogue. If u wanna install 2 wastegates, i think there are ways. But can u show me the turbine outlet flange..?

speed2horizon, 0.7 bar still ok for my default driving. I went to the mech last saturday but he did'nt open the turbo. i cant take the turbo flange pic. My car will be on the road expected this coming thursday. the day i went to workshop the engine still lying outside just finish install new timing belt & waterpum. I was thinking this afternoon going to the workshop take both manifold and send to welder to weld the wastegate. But it will delay the car's work progress. I rather wait longer time then later found out that i need to change the actuator. might as well i do it now. issit possible. where to buy the tial bTW?
