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!

Was yours the white the GTST? Was there at the same time as mine 'cept I was without mine for 10 weeks!

Nice result too BTW. :mellow:

Yep, Mine was the Polar White GTS-T with a couple of Scratches which are being fixed very soon.

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

    • I don't understand how this hasn't boiled down to - Upgrade the turbo when you have everything required. ECU, injectors, fuel pump, turbo, etc. Do it all at once.  If you don't have everything required, just enjoy the car as it is and keep saving up your pennies. 
    • Sounds like you've got an interesting adventure ahead here with local support if you have trouble! My guess is that, unboosted, you will be OK with a small upgrade like -9. What will happen is that once the stock ECU sees more airflow than it expects it will add a heap of fuel and pull a heap of timing to be safe because it can't understand how it could get that much air without there being an issue. You will see clouds of black smoke and it won't pull hard through the midrange and top end. So, overall it will be a bit frustrating but should be OK. If you are still nervous set the base timing back 2o through the CAS, but it will be even more sluggish everywhere. As said above through...this is not my guarantee your engine won't be blown into a million pieces, leaving you looking for very hard to find parts A better idea is get a computer with logging ASAP, wire in a wide band O2 sensor and a use remote tuner. I've done multiple cars this way and while it is not as good as a specific tune on a dyno they can get it 90% right. I'd suggest if you can afford an R33 GTR these days you can afford an ECU and tune. And if you can't afford that you sure won't be able to afford the rebuild if it goes bad in the meantime,.  
    • Yeah it would be nice if someone took the time to put that sort of information together, but there are a lot of variations in looms. I think you are making this way hard for yourself if you just want to get it running....sourcing an SR20 with the right wiring will be a billion times easier than matching the RB loom to an S15 chassis. If you do end up going this way, you just need to trace every wire in the loom with a multimeter, 95% of them will go to a location you can confirm at the ECU.....and then post it up for the next person who needs it  
    • Just top it up with water, and keep a general idea of how much you added. It is normal for water to be pushed into and pulled out of the reservoir through the cap, and it should not be more than half full or it will be likely to overflow when hot. Any decent mechanic can do a pressure test of the cooling system to confirm if you have a leak. Keep in mind if it is only leaking a little and when hot it may well evaporate before you see it hit the ground
    • I'd ask the shop what they used and use that. Mixing coolants is sometimes OK, sometimes not, and you have know the details of each coolant to know whether it's a good idea or not.
