ICM Removal Question - HELP!

[Rabbi]

Ok guys im going to the junkyard today to pickup the ICM from my old z34. What size sockets do i need to get the ICM out?

Any other tools that i will or may need to get the ICM out as well?


Thanks guys!

don't remember the sizes but i think its eaier if you unbolt the x-over and remove the front manifold. opens it up alot. I do remember its kind of a bitch. i would just take a complete socket set with. and a extention and a swivel/universal.

If you don't need the icm mounting braket i think you can just take off he 7mm or 7.5mm coil bolts and once all coils are removed i think the icm is lose at that point iirc.

The bolts for the coils are actually a goofy size. It's 5.5mm if I remember accurately.

Yeah, thats right. I was thinking it was 7.5mm but they are smaller.

Since it is so hard to get an ICM off of the early (91-93) DOHC's, I would think you would want one from another 90's 660 car. Much easier to remove off of a 3100sfi, Right?

Just grab one off a 3.8 its the same thing. The z34 has 4 bolts that attach it to the block and they ar 13mm. I have no idea about the 96 z34. I would just pull a 3.8, its right in the front.

3.8 coils are the same. the controller is very different. C3I

Its not hard once the coils are removed. And yes coil bolts are 5.5mm

Hey man, chris, I liked your mounting spot for the coils, so I copied it,lol. Almost done with the OBD II swap and then I will shoot some pics up
