replacement actuator for 3071 tubby

just wondering wondering what would be the best replacement actuator for a 3071 want to run around 1.8 bar, i have a boost controller.
current one is a forge but bored of rebuilding it

cheers joey

Anyone got an idea? Always had boost tail off up top of rev range with this forge one

Have you not thought about an external wastegate .... not really sure about other makes of acuator i always thought the forge one was an upgrade so to speak ...

what spring rate is it ?

Didnt really want to go external unless its for a bigger turbo, spring is the strongest one they sell think it 1.6 bar it does make 1.8 bar just doenst hold it

Could you remove test it on a vacuum tester or send it somewhere that deals with and get it checked? How old is the spring?

If you really want to keep internal, what about the turbosmart twin port internal gates?

This site only has Borg Warner ones but turbosmart do a universal one also

What boost controller do you run joey? Does it hold boost on a manual daws device controller?

Yeah may not be the actuator causing the issue, I know some older electronic boost controllers can start to play up with the solenoid

What do forge say about it ?

The spring is new, i guess i could test it i just assumed it was a actuator issue.
Have hks 5 boost controller it is old now tho i guess, havnt spoke to forge about it to be honest.
Woody ill take a look at those now

Push forge thst you think it's there product of nothing else they should tell you the full specification of your actuator. E mail and then you can post reply up here if you need further advice on there reply

Yep good idea ill email them now

Try running boost directly from boost source with a Dawes device
pop it down one day when were a bit quieter Joe and il try it for you if you like plus give her a run out on dyno to check fuelling and so forth

My monies on a faulty boost controller.........Dawes device is much more accurate

Haha you beat me to it! Thats what I was suggesting run it with a dawes and see how it runs cheap and easy to test rather than ripping actuators out all the time

Good shout bob, will do that then mate is a very old boost controller now so would make sense if it was that i guess
