Wastegate

[STAGE-A]

Might be a question for the "forced induction" but thought id ask here first in case anyone knows, with the new hi-flow turbo im about to put on it doesnt come with a wastegate actuator so can i use original stock one or do i need to upgrade the actuator ? im looking at only runnin 1 bar if that makes a difference.

Cheers

Is it a standard turbo that's been hi-flowed, or a completely new turbo? If it's a hi-flow, it *should* already have a wastegate on it (assuming it's a Skyline/Stagea turbo that's been used to do the hi-flow).

Not sure if you can use the standard one, though - sorry, can't help you there.

I dont think you know what a wastegate actually is

Thanks, dude...

Meh, just realised the error of what I was saying (and no need to check howstuffworks.com).

I was actually thinking of the actuator - stupid me...

CORRECT INFORMATION: So obviously it's not a Skyline/Stagea turbo, so you will need to add one - can't use the factory one because it's part of the turbo and can't exactly be removed.

THAT's the wastegate... If your new turbo doesn't have a "little flap thing" like this, then you need an external one.

And if you need an external one... thats a mission

he means the actuator i bet, and i'd say the stock one is fine, but not 100% sure, sk will be able to answer that easily

stock actuator is fine as long as you control the ammount of pressure that goes to it, say via any boost controller

You'd be surprised with high flow turbos... I've seen the stock wastegate actuator leak boost at high RPM because it was going way over it's operating efficiency (?!?)

If you are looking to get a actuator for the Nissan turbos; go the HKS Adjustable Actuator. Not very expensive and definitely worth your money over a stock item.

ya reckon the 10psi spring?? does it make a difference if i want to run 14psi??

couldnt find any on nengun, anyone know if this is a good buy?

[satanic]

That's the one; it's cheaper on Nengun though by around $60
