engine swap on a gu series 4

[moparcm]

hello to all. my zd30 decided it didn't want run any more, so i am swapping over to a 4.2. i have a few queries about parts that may need to be changed. i no the bell housing is different but can i use the gearbox thats in the car? i have engine mounts for the 4.2 as they are different. i know i will have to do a bit of rewiring. would there be any other major changes that would need to be done.
thanx all for youre time.

You can use the ZD belhousing but you need to modify where the starter mounts.

If you have the wide radiator, not the skinny tall one, you can use this just need TD hoses ,including heater hoses.

The gearbox is fine to use.

The crossmember you will need a TD one as this pushes the motor forward 10mm. Otherwise in reverse the exhaust manifold hits the firewall.

Get Killa Kustoms to mod your loom, so much easier than trying to work it out your self.

You'll need the weld on engine mount brackets to weld to the chassis. Patrol a Part sell these.

TD accelerator pedal and cable.

Clutch and flywheel of course, although I am told the ZD clutch fits. Just get the right one though and be done with it.

Thats pretty much it from memory.

thanx for the info.
i do have the td42 bell housing. have also just got a new radiator to suit both the zd and td. using the td crossmember will it affect the tail shafts at all?
i have got the engine mount brackets from patrol a part. also have the pedal amd cable. my dad is a whiz with wiring so will leave that up to him.

It won’t worry the tailshafts at all. There’s plenty of room for movement.
If your doing the wiring yourself your gonna need the adapter thingo for the tacho. Not sure what it’s called sorry.

Great News Brother, one less wire to worry about versus the TD42Ti injection pumps, I’m lead to believe from newer variant owners. Was it an immobiliser Ti 11mm pump extra thingy?

can the zd crossmember be used? i cant seem locate a td one.

You can but like I said, in reverse the exhaust manifold hits the firewall. And makes a horrible noise in the cab. Been there and done that.Theres only 10mm difference in the transmission mount spacing, not much.If you could fab up a adaptor plate to use on the ZD crossmember that would work.

Is there any overheating issues retaining the ZD original OEM radiator system versus installing an OEM TD42 radiator system?
