Vr6 engine knock

[grassy 4]

My vr has started with a knocking noise as of Friday. I went to over take a car and when I put my foot down it didn't seem as powerful at high rpms like normal, I checked my oil temp and it went up pretty quick to about 106 which worried me but it was a very warm day is this normal. Barely see it go past 102 usually. Within 5 minutes of getting home coming up a hill I heard a knocking noise coming from it so I got home steady to save it.

I'm unsure whether it Is a spark knock/preignition or rod knock.

There is no noise at idle just between 2-3k rpm

No lights are on the dash.

Engine is obd1

Any help is greatly appreciated!

im not sure its that at least i dont think it is. timing chains and guides are all new. ive done 600 trouble free miles. its in a mk2 the first engine i had was a new rebuilt one but it started knocking badly which i knew was bottom end so i pulled it out, bought a replacement engine transfered a few parts over to run it on obd1 wiring loom as it was and obd2 engine originally. but now im having problems. it sounded like a bit of a mis-fire at over 4.5k rpm you could feel it really lacking in performance
