My engine is making a loud knocking noise iin the bottom like from the oil pan
89 honda Prelude B21 dohc fi
I was driving and i parked and when I restarted my car there was a loud knocking noise coming from the bottom of the engine. Like where to oil pan is. it will crank and I can move the car but have to have it at like 4000 rpm. What could it be and should i just buy another engine? I want to get a acura integra b20 would this be better?

Did you check if you have enough oil in the motor? Sounds a lot like rod knock (spun bearings).

You can't put an Acura Integra B20 in it dude, it's a completely different engine. 
Sounds like you need to have a shop or someone qualified look at it.
