Hi guys, i'm new in the carworld and finally got myself my dream car. the R33

I bought a 1997 40anniversary R33 GT-S 3weeks ago. I gave it a service(change oil, oilfilter and sparkplugs) and the car runs great.
I don't drive much.

20minutes to work, and 20miuntes back home. There are times when the car is on for more than 30minutes(Incase i have to drive my gf somewhere before home) that my car sound turns into this gruggling noise but my meters seems like nothing is going on.

One thing that comes to mind that i am not using a coolant. Just using water atm in the radiator and i think that the water becomes so hot that it maybe causing the gruggling noise to happen.

I can get home, turn off the car and start it back up tomorrow and the sound is back to normal like nothing happend. just that if the car is on more than 30minutes i hear the gruggling noise(doesn't sound like a bubble noise, just a harley davidson idle ish overheat noise idk how to explain)

My car is currently at 394WHP if i'm on stage B(22psi) but its currently on stage A(16psi).
I tried hitting up 3 local mechanics but they told me it could be my thermostat or a blown headgasket but they seem too busy to give a hand. So i thought to ask on forums.

I thought maybe flushing the radiator untill the water end up coming out clean, and get an antifreeze coolant should do the trick but idk if the issue might continue.

Any help would be nice

      Yeah, you are right. It seems easier and more reasonable to boost the engine. And as you said the blocks are very similar but the cylinder bores are different.

      Anyone know this frontpipe?

      Sound logic, but in actuality way more illegal than just having the wrong pipe. Normally, doing something like that would be forgery. Meaning you may have certain documentation for vehicle parts, but the actual parts are different ones and you just assign them the numbers and badging from the documents. But nevermind that. Nonetheless, I AM curious if this pipe was ever made by any official manufacturer this way, because I honestly am not familiar with this pipe layout and shape. As I will be putting on the HKS Silent Hi Power once my exhaust gaskets arrive, as long as it sounds right I will just roll with this front pipe. I can always order the actual Mines part if I run into legal issues. It would be an unnecessary expense as there is lots of other problems I have on this car as of now.

      So, weld a plate with the Mines logo laser cut into it, onto it. Instant Mines pipes, whether they were or weren't originally.

      I don't know if the blocks are "the same". They will be very very similar. Obviously, either the bore or the stroke is going to be bigger on the 20. If the bore is bigger, then the 18 head is unlikely to fit properly. If the bore is the same, then you can almost certainly fit the CA18 head, but there migth be a few fun things you have to do to make water galleries (or other things) line up properly. Or... it could just be real easy. Is it worth the effort? Almost certainly not. You can make nearly as much power on a 2 valv ehead as you can on a 4 valve. There's not any "magic" in a 4 valve head.
