i measured back pressure on a -10 equiped rb2630 we had at work that just would not makle power over 18psi.

on 14psi there was 25psi back pressure. on 18-20psi it had 35-40psi back pressure.... (30psi boost guage the needle wraped around to 0.. and our dyno can only read 30psi.

What power did that particular engine make on your dyno?

Just need someone with 2530/-5 to take the plunge and try a cropped GT30 exhaust wheel as above and use the HTA 68 front wheel and hope for the best! If its to laggie 3ltr it!!

you want me to try what? :D

i'm in Melb, dealt with Stao quite a bit before with my GT-T, nice little high-flow on that car, punchy little number.

So what are we trying to do with the 2530's? in laymans terms, i'm terrible when it comes to turbos, other than a 3071 is less laggy than a 3076, basic crap like that :D

are we trying to make them more responsive and powerful at the same time, or just more top-end out of them? I'm running 2530's in the R

Attempting to push 2530's harder! Whats the consensus of whether to open up the entry to the wastegate flap on hks 2530's? More area on the flap would apply more force to blow it open?

These could be my next upgrade (4th set) of actuators the dual ports look real nice!

Now i wonder if running boost pressure to the bottom side of the gate will enable me to crack 30psi up top with the 19psi actuators or head straight to the 35psi units? Be interesting to see base pressure with the 35psi ones! :domokun:

The reliability of the stock extruded manifolds are great but at 460awkw i wonder if theres power there aswell?

Nice looking actuator!

Where did you get the manifolds extrude honed?

Berry's GTR used to be (still is?) on stock manifolds, surely they'd know if it's a restriction so maybe call CNJ Motors in Queensland and see what they have to say?

UAS organised the honing back in 2004 not sure if there still doing it..

Maybe hypergear could join the conversation with a few options on high flow bolt in low mount GTR turbo's that give 50-60AWKW extra than current offerings without masses of lag??

      KW only offers a set for the R32 GTR. Popular options are D2 racing, Ksport or Öhlins. I have a D2 Racing coilover set, though I don't know for sure which one.

      Well, the good news is you have more than one very good option for new coilovers in and around your country. Worth the drive over to KW to talk about GTR stuff.

      Fair enough, I am in no way a tire expert so I'm not familiar with all the terms and conditions. I'll definitely note down the AD09 to potentially try in the future. Rain is not too big of a concern for now as I will probably only drive in the rain when I have to. And considering I still lack experience driving the GTR I'd more than likely take it easy too. I have coilovers in the car but as I barely got to drive so far I never bothered to even check if they are adjustable haha. The suspension is almost entirely old and worn as well so I suppose when I eventually fix that in the future that would make a huge difference.

      There's not a great deal to report here .... except ...... FOR .... LSD!!!  I bought a Quaife LSD from the UK and shipped it here .... Wish I'd just bought locally cause the shipping and duty was $700! But there were so many diffs used in the E90s I just wanted to be absolutely certain I was getting the right one so I spoke with a supplier in the UK who builds race cars and they have heaps of experience with the E90s.  I pulled the diff out which was seriously awesome - I've never done anything like that before, I must have watched 1000 videos on YT about it as well as consulting the Bentley manual. It was super easy in the end. The diff was delivered to the awesome folks at Hornsby Diffs and will be back in a few weeks. I also replaced the diff bushings with some Nolathane ones.  Really looking forward to getting it back and getting back to the track or even the skidpan.

      yeah... the 13kg/mm springs weren't always in there, I had 10kg/mm but doing a few SMSP commanded heavier front springs. It's so good now going into T1 and T2, just need more seat time and real tyres.
