i have a 90 240. is there any mods that have to be done to drop the dohc engine into my car? i want to turbo the dohc ka. please let me know of any problems i will encounter with this project with the swap and the turbo and fmic...thanks

i know that you will need to tget the p/s reservoir
the a/c lines are also different
you will need mounts
i don't know about much of this swap

the fmic will need holes made for the piping, the turbo should fit fine if its a kits with minimal relocation of items

you do NOT need mounts it is a drop in swap. I did it on mine. All you need is powersteering lines and a pump off a 91-94 240sx. Also there is a little wireing involved. There are 2 plugs by the battery (they connect but the wires are in diffrent spots) you have to cut the connectors off the harness and off the harness built in the car and match all the colors up. Thats about it and you will need the ECU off the DOHC.
