Koyo Radiator Questions R32 GTR

I received my koyo 53mm radiator, this one to be exact: http://www.rawbrokerage.com/koyo-53mm-aluminum-racing-radiator-for-nissan-skyline-gtr-r32/

Looking at it, i am slightly confused. There are three ports:

1: Small port, looks like 1/8 npt, it came with a blocking screw already in, with a ton of teflon tape, I unscrewed it to make sure it was a npt port but the sender from the autometer gauges does not fit. So whats this port for?

2: Large port, looks like it would house an adapter for a gauge sender. both adapters from the gauges do not fit. Did not come blocked off. Is this where the stock sender for the car goes?

3. That's a drain plug, I'm not that crazy. lol!

 

Thanks in advance

The one right next to the bottom radiator hose is for the thermo fan sensor and the one on the other side is the drain plug


Thermo fan switch, got it thanks.
lol I knew #3 was the drain plug.
Now what about number 1?

      RB25DET with solid lifters - which cams ?

      They are under bucket shims. Tomei provides a test shim kit and then any measurement of shim required.

      I always wondered how you were supposed to buy a set of 24 buckets and somehow magically have every single one of them yield exactly the desired clearance. I would have thought you'd need to assemble a cam with either 12 "sample" or "example" buckets of known top thickness (or a single such sample/example 12 times over!!) measure clearances at every valve, and then do the usual math to work out what the actual "shimness" of each bucket needed to be, before buying the required buckets to make up he thicknesses that you didn't have on hand.

      I now seem to be limited in power due to my rev limit/hydraulic lifters in my built RB25. I'm looking into converting over to Tomei solid lifters. Question for anyone that has done the conversion. I was always under the impression that when using the Tomei solid lifter conversion, you would also require new valves (Longer or shorter stems, I can't remember which).  I don't know where I got this idea, as so far I see no mention of this in any of the Tomei documentation. It just states I need the Tomei solid buckets, solid lifter cams and upgraded springs. As my head is already built, all I would need is another set of 1000$ Kelford cams, 500$ buckets and about 4H hours of my time installing and I'm off to the races!?!? There's no way it's that simple, I must be missing something?

      Why am I hitting a power wall with my stroked RB25?

      I couldn't agree more. I should have started from the get-go with a NEO or solid bucket conversion. I started looking into converting over to solid lifters yesterday. Now for some reason I was always under the impression that when using the Tomei solid lifter conversion, you would also require new valves (Longer or shorter stems, I can't remember which).  But I see no mention of this on any of the Tomei documentation. It just states that I need the Tomei solid buckets, solid lifter cams and upgraded springs. As my head is already built, all I would need is another set of 1000$ Kelford cams, 500$ buckets and about 4H hours of my time installing and I'm off to the races!?!?
