yes, and no I won't bring you back any parts/kobe beef/school girls! haha just kidding mate.

Yeah, I'll be heading back soon. it's worth it for me just for the money saved on freight.

BTW your dyno graph really impresses me. I'd love to come for a ride to see what your car feels like. ie. how responsive, what the top end is like etc. because I'm pretty much doing the same things.

I currently have:

front pipes + cat back system

Apexi PFC

profec b-spec 2 (running about 12psi)

Apexi power intake kit

trust cam gears (not yet tuned)

HKS wastegate actuators

want to add to this:

trust dump+front kit

cams (not sure yet which ones) + valve springs

possibly GT-SS turbo kit

Richard, that sounds like a good list - I think my turbos run out at the top end, so something like a GT-SS will keep the boost on early yet flow alot more for better top end :)

If you're ever in Melb, I'm happy to take you for a spin :)

I do pop down to melbs from time to time. mainly when the GP is on :)

yeah, I think the GT-SS would be worthwhile. not very expensive either. still tossing up whether or not I should go one further to the 2530s.

GTR032 can you please post your graph?

Thanks :D

I dont have my latest graph unfortunately but here's the next best thing. 244rwkw, Blue line is 14psi, cam gears, power fc, filters,full exhaust and rebuilt turbo's. Red line is 12psi, pods and full exhaust - 188rwkw.

Clarification: So 1bar worth of boost on the stock turbos seem to be okay? Is failure past this because of the actual boost or the fact that the turbine shaft speed is too fast causing delamination?

The reason I ask is because I am about to undertake up grades in the way of a competition dump pipes and y piece as well as a retune on the dyno. I already have a larger free-flowing FMIC and pods. What worries me is that with all these mods I will have less restriction in the system and therefore less boost. If I then up the boost to 1bar I would imagine the shaft speed will be greater than a near standard system with 1bar.

Am I on the right track? If so, should I tune for 0.9bar or even less?

So is it the boost or the shaft speed?

Still had no concrete reply. Given that I have less restrictions in the system should I be aiming at only 0.9bar boost or less? So is it the shaft speed that causes the problems or purely the amount of boost?

West - can you post your dyno so I can compare the midrange to the Tomei cams?

I'm sure with cams you'll get more midrange than mine, i can post the dyno graph but it'll take a while, best to speak to BEN, my car was on the same dyno as your or maybe come to the meeting this month?

Where about in melb are you? Pm me.

    • No, code 21 is very straightforward. It can only be the things described in that diagnostic flow. In fact it has no way of knowing that the spark plug resistance is out of spec.
    • Hi, SteveL Thank you very much for your reply, you seem to be the only person on the net who has come up with a definitive answer for which I am grateful. The "Leak" was more by way of wet bubbles when the pedal was depressed hard by a buddy while trying to gey a decent pedal when bleeding the system having fitted the rebuilt BM50 back in the car, which now makes perfect sense. A bit of a shame having just rebuilt my BM50, I did not touch the proportioning valve side of things, the BM50 was leaking from the primary piston seal and fluid was running down the the Brake booster hence the need to rebuild, I had never noticed any fluid leaking from that hole previously it only started when I refitted it to the car. The brake lines in the photo are "Kunifer" which is a Copper/Nickel alloy brake pipe, but are only the ones I use to bench bleed Master cylinders, they are perfectly legal to use on vehicles here in the UK, however the lines on the car are PVF coated steel. Thanks again for clearing this up for me, a purchase of a new BMC appears to be on the cards, I have been looking at various options in case my BM50 was not repairable and have looked at the HFM BM57 which I understand is manufactured in Australia.  
    • Well the install is officially done. Filled with fluid and bled it today, but didn't get a chance to take it on a test drive. I'll throw some final pics of the lines and whatnot but you can definitely install a DMAX rack in an R33 with pretty minor mods. I think the only other thing I had to do that isn't documented here is grind a bit of the larger banjo fitting to get it to clear since the banjos are grouped much tighter on the DMAX rack. Also the dust boots from a R33 do not fit either fyi, so if you end up doing this install for whatever reason you'll need to grab those too. One caveat with buying the S15 dust boots however is that the clamps are too small to fit on the R33 inner tie rod since they're much thicker so keep the old clamps around. The boots also twist a bit when adjusting toe but it's not a big deal. No issues or leaks so far, steering feels good and it looks like there's a bit more lock now than I had before. Getting an alignment on Saturday so I'll see how it feels then but seems like it'll be good to go
