Hi, Just got my car back today from RacePace. Ben & myself are very pleased with it.

I had someone sell me the wrong Spring for my wastegate - wanted 14.5 or 15psi spring but got a 25 or more?

Anyway Ben had a 10psi spring and the car made 284.6RWKW @20psi. I will be putting another spring in & try for 300RWKW.

The car feels great & Ben was right - It does feel like a lot more than 285.

Cheers

Chris

What size turbine housing?

Very nice complete setup. :)

Hi Cubes, I think it is 0.62 for the housing. I will check tomorrow. Sorry I have to go out again!

you running a 3.5" dump also?

thats gonna make the difference that i didnt have :D

Also you got the slightly smaller one... hence the extra psi to get to 280

I'd take a staby-stab at it being a .82

If its a .63 then thats amazing results

Another quality job. Good to see that the stock cam'd RB25 heads pumping great power without the need to spend $$$ on em :D

Thanks Ash, I think you are right, more likely the .82. I must have been looking at the cover size. I'm not sure if it's a 3.5dump, can't remember. I will be talking to Ben tomorrow because he want's some feedback and I'm going to change the wastegate spring, maybe the whole waste gate.

What are your thoughts - Should I stick with a 50mm gate? or put a Original HKS 40mm one on?

Cheers,

Chris

Should be 0.82 turbine housing, not 0.62

if your current gate is giving no issues and its not creeping too much, stick with it.

The idea wuith the rates is to get as close as you can to ur target psi off the gate spring where u can... im sure you already know that :D

mine crept heaps (45mm t/smart progate) in 4th/5th under load @ higher speed when i was using 7psi spring/17psi (bleeder)

using a 14psi spring/17psi (via bleeder) it was excellent and stayed shut in 5th much longer

on 24psi with the juice it was just mental so i didnt have time to worry about it.

find out about the dump, be interesting :D

      new 1.5 LSD issues/concerns

      By GTSBoy · Posted

      I gotta pull you up on this. It's driving me crazy. A shutter is something that closes, like over a window or in a cmera. The word you want is shudder. That LSD is clearly f**ked. Take it to a diff shop and get it disassembled and examined by an expert. YOu might have plates welded together or something equally crazy.

      S1 rb25/s14 starting problem

      By GTSBoy · Posted

      Check the Nistune doco. There are a few assumptions being made here that might not be valid. I will list the things that occur to me: Base map. Base map for what? Base map for Z32? Then the cranking pulse width is probably wrong for an RB25. The extra 500cc of capacity might well be enough to prevent it from catching. Base map for RB25? I don't think you can load one of those into a Z32. You have to just make the settings correct for an RB25 in the Z32 base map. That is either K or the TIM to get the pulsewidth right. Loom. You bought a loom for an RB. And you plugged it into a Z32 ECU. Did you make sure that any iwre differences were swapped. From memory, there's at least a couple. And as per the others, I would suggest making sure that the fuel pressure is correct while cranking and that the injectors are actually flowing as expected. They really must come out and go on the bench, unless you do find that you have messed up as per above points. I would also suggest watching in Nistune to make sure that everything is reading correctly. That the correct binary flags are raised at the right time (like the crank signal), that there's no stupid values in K or TIM. That you have not got mismatched firmware for the ECU and/or a wrong image loaded.
