Okay, hi! I have a 1993 240sx and I just pulled the motor. I plan on placing in a rebuilt S14 motor. I know to swap out the dizzy and atleast the lower part of the intake manifold.

This is where I get confused as to this being the first time this deep into an engine. The engine has been ran for about 1k miles and I just re-sealed the oil pan so I know it runs. It has been out of a car for several months but is squeaky-clean. I need to try and get it to TDC in order to put my S13 dizzy in for the timing. Is it okay to go ahead and rotate the crank or should I get some more oil in it first? I am concerned about F-ing things up.

Now the other part. The intake manifold. The S14 manifold already has the EGR stuff deleted. SO, all I has to do is unbolt the lower half off my S13 and bolt it to the S14 upper mani? Anything tricky or special I have to do? I have looked online for answers but nothing is specific enough. They all just say that it works and the S14 top mani is better due to no butterflies or something of the sort.

Is there anyone who can confirm and/or tell me how to do this correctly? I do plan on turboing this engine. The S14 engine is already tapped and set for oil and I already have a T2 manifold.

Thanks and any help/information is much appreciated!
