Probably already a few of these threads but here is another.

I have resently installed a ca18 rad into my rb20 r32 and am having troubles with pressure inside the rad. There is no milky substance in the oil and im not losing coolant, but when I open my radiator cap after 24 hours since the car was last started, heaps of coolant spills out. Im pretty sure I have bled it properly. The radiator cap has a 0.9 on it and I cant find what the correct number for rb20det. Can anyone tell me what is causing this and what the corrrct cap is. Cheers

how low is the radiator compared to the engine?
is the overflow hooked up properly, does it flow propperly when running?

seems odd to spill out when cold, something is either holding pressure when the car turns off or the radiator top is lower than the rest of the system. both are odd.

      Yeh I think i'll message an old contact i had for ages that manages his own tyre shop now.. n tell him what i want n work with him before ordering..  Got this 17x9 +30 Driftteks on 245/45/17 PSR Drag Radials on the rear.. They fit well - for your reference in future - Rear guards  have been lipped in & minimal to non flaring of the rear Gaurds.

      If only it were that easy! I also needed to remove seats, shocks, brake calipers, send my car through a fence, and use measuring and ended up guessing because I didn't remove seats, shocks and brake calipers. It can be hard sometimes Can be a little more complex than 'just measure' if you want to truly measure the entire wheel through all of it's suspension travel. But if you aren't going for every last mm then yeah, you can check the space you currently have and guesstimate.

      If you own a car, and it has wheels on it, and you know the offset of those wheels, and you have a measuring device, you have everything you need to work out if other wheels will fit.

      MAJOR FUEL ISSUES 25det neo r32

      Put a clamp on your return line. I have a feeling it's sucking air, and introducing bubbles to your fuel. With a lot of fuel, less problematic. I'd honestly be redoing all the lines in the tank and clamps on everything.   Also, you've given two different answers to the same question: Asked if being followed by the police you could get down to use the whole tank, you said yes you could, so long as you keep off boost. However, you then followed this up that free revving, it would also cause the issues. I'm doubting free revving is enough to make any noticeable boost on what is likely a decent sized turbo.   So now I have to ask, can you actually drive it lightly and use all the fuel, or does it break up even free revving? Also, have you put a fuel pressure gauge on it? Can you hear the pump change noise at all when you're having this issue?
