SR20 problems?

i bought an SR20 180sx from world car link recently (still in japan), i dont know a whole lot about the sr, but im just wondering what kind of troubles do the sr’s have if any? ive heard that the water pumps arent too good. anything else?

I have had mine now for over 30,000kms, Had no problems besides replacing the clutch. has original water pump.

in my opinion very solid engine, I havent had any problems with mine or even feel there is a problem coming. Ive only driven it for 5000kms though

wait wait ill say it CA is better

before i parked mine for the winter, it was very reliable, with that in my 240, its a blast to drive.
