Doesnt matter if its a redtop, blacktop, bluetop, pinktop etc, you need to do preventative maintenance on it before dropping it in. If your so stingy to change shiet like thermostats, water pump, belts, oil pans, etc, then you will end up paying alot more in the long run when that engine starts having issues, because you gimped on it when you did the install.

The difference between a S13 redtop/blacktop is a couple hundreds, tops. You want a reliable engine, blacktop wont be a good candidate (for me atleast). Why? All blacktops came from 180sx in japan. I have yet to see a 180sx that hasnt been BEAT TO HELL. Go find an automatic SR engine and youll have a better chance of finding them in a better condition and less abuse. It doesnt take much to make them work with a 5 speed tranny.

yea, that's right! i just did a swap in my 1991 240sx with an Automatic SR engine, well what can i say it runs perfectly and reliably, soon, i will rebuild the motor, just in case.
