turbo question!

[BlAcK95sE]

i blew my stock turbo for the second time... so i upgraded to a hks 2510, and i haven't been able to find a waste gate actuator for it... my question is would it hurt my car or my turbo to drive the car with out the actuator?

W/out a wastegate actuator, you basically have no wastegate. This means you have no way of getting rid of the excess pressure at the turbo.

If you drive like Grandma and never get into boost, you'll be ok. But if you get on it just once, you'll spike boost and wreck something.

Shouldn't be a problem, you just wont really make boost well... Your car might also run like **** because of that.... So would personally wait, not much point.

o. i see. i thought the actuator stayed shut untill the set PSI was reached then it opened to relieve excess pressure in the turbo...

Without the actuator, the gate will stay closed right? In which case it won't vent any of the exhaust gas after you hit what should be your safe boost limit, and you'll just keep building more and more boost...

Or is the other way around... with no actuator, the gate stays open and it will never build any boost at all?

no the valve that vents the wastegate gasses is just on a hinge the actuator is what actually keeps it from opening on its own. So it will just always be venting...

perfect example right there. heres a 2530 with no actuator.

on its face its closed from gravity

On its side you can see the valve is opened from gravity pulling it open.

well i just need to drive my car untill i can find one/ afford one. hks discontinued the acuator for the 25XX series turbos. now the only place i can get one form is Japan. my wife and i only have 1 car now and it kinda sucks.

so would it be ok to drive the car if i don't take it above 3000 RPM

yeah you should be ok. Be nice to her though and find an actuator asap!

bingo.

@BlAcK95sE:your car would run NA. you should be fine like that. make sure oil lines are connected to avoid damaging the turbo. you can make a bracket and mount your stock actuator on there. or you can do the poor man wastegate with a long spring for temporary boost. http://www.97supraturbo.com/New%20Turbo ... %20(4).JPG

the adjustability is a good thing

Or you could check ATP Turbo.They have tons of stuff there.I mean a whole page devoted to wastegates and actuators.

hey thanks for the link! the cheapest i could find them for was 190 shipped! should i just order one for the t28 or the t25.

i am guessing that since i hve a gt2510 i should order it for the t25?

[BlAcK95sE]

so will the actuator for the t25 work???
