Hello all,

Thought I will create a thread detailing my radiator upgrade.

Decided to buy an ASI 52mm radiator for r32 gtst

As with all chinese radiators, the water temp sensor thread is the wrong size and hence it has to be enlarged in order to fit the factory sensor.

Once fitted, there is no space for the factory engine fan and shroud. (unless you heavily chop into both)

When fitted, there was only a clearance of 6.8cm between the radiator and the power steering pump pulley. Therefore only the slimmest thermofans on the market would be my only option.

I ended up purchasing Flex-a-lite 420 slimline thermofans (6.7cm thick)

Brackets also needed to be purchased to fit the thermofan onto the radiator.

The power steering lines also got in the way. Therefore they were modified so they ran to the side of the pump as shown below. You can see the U-bracket which used to guide the hoses.

Final results; There is 1-2mm clearance between the pulley and the plastic mesh surrounding the fan blades. The fan blades sit further in, so if there is any movement, it will not hit the blades.

Thanks to Revzone in Ringwood, Victoria for installing the lot! (customizing the power steering lines and mounting the thermofans onto the radiator)

Conclusion:

- Dont get 52mm radiator :banana:

- Whilst driving on the street, water temps sit on 78-80degrees with no thermofans running (weather temperatures ranging from 8degrees - 18 degrees)

Hopefully others will realise the challenges of fitting a 52mm radiator and have a good think about it before purchasing.

Thanks again to Revzone

- Patrick

Just for other curious members' info, I also have one of these fitted to my RB26. With the factory fan + fan shroud fitted to it, there is only a TINY gap between the fan and the harmonic balancer (not sure if my long nose crank / TuffBond harmonic balancer means more or less space). This also seems to amplify the noise of the fan quite a bit :S

The "long nose" crank is just a longer oil pump drive, it doesn't change where the harmonic balancer sits. The aftermarket balancer is probably bigger though.

      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

      By MBS206 · Posted

      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?
