im pullin a f23a1 out of my wrecked accord is there a link where i can get some info. i pulled a h23 out of a lude and dropped a jdm h22 before but for that project i had the lude haynes manual.

as for my questtions here they are:
Is there a knock sensor and a oil pressure switch under the intake manifold or any type of wiring on the back side of the engine???

 

if you pulled out a h23 and installed a h22 in a prelude, this should be cake for you...
in fact, the accord motor is smaller than the h23 and h22.

as far as the knock sensor, no to sure. but theres should be an oil pressure switch under the intake manifold by the oil filter

 

yes there is a knock sensor under the intake mani. i broke mine when i was pulling my engine so be careful, it was 170 from honda lol.
