240sx dohc swap

opie240 · 11-15-2008, 05:05 PM

What all is required to swap a soch head with a dohc head on a 240sx HB?? I think I know most of it but I want to be completely sure. i know head of course, intake mani. and upper wiring harness? This is all I know of.

too much work and not worth it honestly. just find a DE.

for real... just buy a dohc motor

and the single cam block is a complete differant design.

I have a dohc, with a broken rod and crank, everything else is fine....either way you would still have to swap the wiring harness just as you would with just swaping the heads so i dont see how swaping the motor is so much easier. Im gettin a SOHC car and have the dohc motor laying beside the dohc car i already have. Just wanted to know what all would HAVE to be changed. ECU? Exhaust manifold? stuff like that

I know the compression is a little lower and if i'm not mistaken the rods are stronger? But are the oil and water journals in different locations or what?
