I don't have ac on my car any more and want to fit a elec fan and ditch the viscous

Has anyone done this and use te existing rad fan 25a fuse and relay. Just need a temp fan controller to wire into it I'm assuming?

the existing fan wiring isn't all that suitable for running thermos from memory, as it runs of a little bit higher temp than what you really want.

as for cooling fans though, you are better off with the viscous clutch fan. the power loss of them compared to a thermo is bugger all, and they work just fine. if you are adamant on going thermo though, either go a big single, or a GOOD set of twins that have a shroud already fitted (without a shroud you will cook the engine very quickly, probably in your first drive). something like the thermos from a late model falcon are a good choice (and have been used before by other members on the forum). or some other factory thermos from fwd cars would also do the job

I have a 40mm radiator which has no shroud. The previous owner clipped the blades to get clearance for the thicker radiator

I only want to use the existing wiring for relay and fuse. I want to control it with a separate fan controller

Get yourself a gktech highflow fan & a VL fan clutch. This will be shorter than your current setup, and will work extremely well with a factory fan shroud.

Thermos are a waste of time, and cannot match a clutch fan for airflow.

      By HYBRID VL · Posted

      i have been looking at this ECUtek tunes for my V37 and just wondering if i but it and put it in my ODB connector if i just remove it when the vehicle is off are all the tunes removed aswell ? like basically removing the dongle puts the car back into a standard state? i have never played with ODB connectors with tuning i have always had full ECU with hand controllers so this is all new to me.

      100%  This was also considered however the whole 370Z caliper came up at a good price and I couldn't suppress my temptations to buy it and take me further and further away from owning a factory fast car in the future. Nissans addiction is worse than a meth addiction.

      You could try some less aggressive pads on the rear. I found (a long time ago when all my brakes were stock 32) that using the same (Bendix Ultimate) pads at both ends made the rear bias excessive. I strongly suspect that the stock Nissan pads probably use a different material, but aftermarket pads will usually be the same material regardless of what pad they are put onto. That bias situation did get better when I put R33 calipers on the front AND used the same pads - just transferred them from old to new calipers. So you should feel the difference with the change you're making. But certainly do not forget the option to change the rear pads down a grade or two.

      Ha ha, sorry dose, I wasn't meaning to argue the point on "it'll do f**k all". I was only shining a bit of a light in the flawed logic you used with it mate.   I 100% agree that there is zero point changing stock manifold with a stock turbo, unless the manifold is f**ked. And only reason I'd ponder aftermarket manifold on a stock turbo would be that I'm too scared too look at the potential ludicrous prices people are asking for a stock manifold! Ha ha ha

      Can someone tell me what this part is for? Someone duct taped it.
