Koyo Radiators Options

[elvasoshexai]

so my radiator cracked and i'm looking for a new one. but had a couple questions

For those using the all aluminum racing radiator (R1958), how many of you actually changed the thermostat/water pump (whatever else is needed) to achieve lower temps?

Koyo also makes an OE replacement (A1575) that has a copper core and plastic tank. does anyone have this? is this as thick as the all aluminum one?

and i'm just deciding on which to get. i read a few old posts and it seems like most people with the R1958 all alum radiator don't change anything else, so it seems like they aren't taking advantage of the better cooling anyway.

so i'm wondering if i should just get the OE replacement one for about 1/2 price. (i will be going 5sfte soon)

does anyone know what aterial our oem cores are?

also, if i go with either the koyo oem replacement or the all aluminum, do i need to buy new fans + brackets + radaitor cap?

your fans and brackets will bolt onto the new radiator, and it includes a radiator cap. but honestly, I noticed no difference at all with the aluminum radiator. I changed my thermostat too, but I just put in an oem replacement.

also, if you are going 5sfte, know this, I have the thicker aluminum radiator and it takes up a bit of much needed space. I had to cut a corner off one of the brackets for one of the fans in order to get the turbo to fit in place, and also now my oil filter relocation lines are pretty close to the fans... you can use it, for sure, but it makes space a little tighter and doesn't really do anything besides look good.
