So, I'm swapping all the external components from one engine to another and am making a list of all the gaskets etc I need, feel free to add anything I've forgotten.

 

2 x exhaust manifold gaskets

2 x manifold - turbo gaskets

Oil and coolant O-rings 12?

Rear sump rubber seal

Front sump oil seal

2x head to lower plenum gasket

Upper plenum gasket

Oil tree gasket

 

Fuel hose clips - any suggestions as the ones I have are complete crap and easily split. Do you use a normal style clip or jubilee clip?

 

Any suggestions for replacing the o-ring style rubber bits on the front of the timing belt covers, new ones are a bit pricey?

 

Cheers guys

Swapping any coolant pipes?

Yes, both front and both back will be swapped. I thought they were just RTV silicon sealed though?

Yes, but i was thinking about thermostat O rings, and also my rubber hoses had corroded onto the aluminium. Just a thought.

Does the thermostat have an o-ring? Mine didn't come with one.

 

All my hoses are silicon and came off fine, they'd only recently been put on there but found the seal around the rear of the crank was badly scratched on the engine I purchased and leaked oil badly so it's just come out again for the new engine!

Perhaps not then, I thought I remembered taking one off.

 

The silicone hoses should be fine to reuse also.

Thermostat gaskets are liquid.

If your going to change the filter tree, change the 0 ring inside it too.

get these fuel hose clamps: https://conceptzperformance.com/nissan-oem-300zx-fuel-hose-spring-clamp-z32-16439-16e0a_p_5657.php

 

These were used on the later model Zeds and are lots better then the older screw type clamps

Good thinking that man, pretty sure I did last time but I'll do it again anyway.

Thanks Lymon, are these strong enough for use with a setup running higher than standard boost?

> are these strong enough for use with a setup running higher than standard boost?

 

these clamps are for fuel lines.. amount of boost is not relevant for fuel lines

OK thanks. I thought the fuel pressure increased with boost hence the vac line

Can anyone tell me the ID, OD and thickness of the timing belt washers and how many are needed?

What do you mean by timing belt washers?

 

Should have read, timing belt cover washers

 

These ones...

Can't help you with dimensions as I don't have one to hand. However your CZP links says 21 are required which tallies here (part 19):

Cheers Andrew, can't get your link to open but I'd read 15 on a couple of other sites so wanted a second opinion :thumbup:
