Al, thanks for the info (only noticed your post today). I did read something a little while ago about someone doing the hiflow with VG30 exh housing and getting good results. I'll look into it as well - and yes, it's also added to my confusion :)

porschephile, definately post up the dyno chart from your friends car if you can - i'd be very interested to have a look. I assume that your friend has the GT2835 with the .87 turbine housing?

Also, just having another look at the Nengun website. They have the 2835's on special for $2,560 delivered to Sydney ;)

One question though, they have 2 versions of the GT2835 with A/R 0.87...one with Strong Actuator attached 80mm diameter and the other with 100mm diametre.

Pardon my ignorance, but what exactly does the actuator do and which choice would be better for my application?

Come on guys - help a novice out :P

Thanks!

The wastegate actuator controls the amount of boost that is pushed through the turbo by pushing excess exhaust gases through the wastegate. The harder the spring is the harder it will be to open the wastegate thus controlling boost.

Not sure which actuator is better, as i am note that technically minded, i usually ask the turbo experts that type of question and allow them to make the decision for me :).

About my combo and your decision, if you could hold off for about 3 weeks i should most definately have a dyno graph to post up. Head has already been sent to be ported, turbo sent to be upgraded, ecu out to be upgraded, cams have arrived, it's all moving quite nicely :D

    • Anything above ~9.5V is acceptable. The higher the better, but it will almost always drop to at least 10.5V, if not lower, even with a new big battery and everything else being good. 9.76 is not a concern. If it goes below 9, you'd be sure that there's a problem with either the battery or the connections.
    • It's new almost. Under a year old i think and I've tested it twice at supercheap
    • Glue the head from a Pez dispenser on it. Goofy, or Winnie the Pooh, so something.
    • Adjusting the idle screw is usually (emphasis on usually) just covering up deeper issues. Stuff like the cold start valve not closing properly. Throttle shaft seals on the way out. Coolant temp sensors getting out of spec. Coolant temp sensors especially can be a bear to diagnose because they can fail subtly. My dad just spent weeks chasing down his high idle. He cleaned the coolant temp sensor and everything but the resistance curve just drifts over time and if it's been 20+ years they also get super slow to respond as well. Has a massive effect on fuel economy as if it's off the ECU is going to run richer and command high idle for far longer than it should otherwise.
    • How old is the battery, it's more likely your battery is on its way out.
