I'm swapping inlet manifold gaskets on my R32 GTR this week

Need to know if plenum bolts need to be set to certain torque?

Any advice be appreciated, thanks in advance.

Theres a sequence to loosen/tighten them in.

And the set torque taken from the Nissan GTR32 manual is 16-21Nm

good luck...!!!

Any idea of the sequence?

And how much torque with HKS metal gaskets?

I used the same amount of torque with my HKS gaskets.

I did them by hand, and then just re-checked them with a torque wrench.

Sequence is a diagram....

9 5 1 3 7 11
10 6 2 4 8 12

Hope that gives you an idea

Thats the same I used on my R34 GTR from the Nissan manual I have.

Are you doing this with the engine in the car? Because if so, it seems to take for ever and you may need to get under the car to get to the hoses and some of the bolts.

This has got to be one of those jobs that really tests your patience!

I removed the engine mount nuts so I could jack the engine up it helps a bit. the alternator and the idle control valve are also best removed.

Its a fun job, but if you know what your doing its not that bad.
Totally agree.

I didn't jack up the engine or remove alternator. May have to try that next time. But hope there is no next time!!!

Yes, engine will remain in the car, but have use of a ramp, so hopefully will be easier..

To be honest ramp will not make it easier, as this has no use. All the work is at the top

I done mine without the use of a ramp

Surely it'll be easier to get to the bolts under the plenum from below the car?

Or at least have a look where they are?

Mind u, in saying that, no job on the Skyline has been straightforward so far.

As usual, it is just two of the nuts which are an absolute bastard, the lower ones on cylinders 4 and 5.

Some people remove the mini plenum underneath, some don't, either way round you will lose your temper atleast 5 times:chuckle:

Ok thanks for all replies

Taking the job on tomorrow, any other things/problems to look out for?

Job went reasonably well... apart from one minor hiccup.

Car wont start!

Its got fuel, but no spark, we've plugged everything back in (as far as we can see)

There are however a couple of plugs under the plenum, we think weve reconnected them properly but its a nightmare to check..

Does anyone know what this plug is? And would this being unplugged cause it not to have a spark?

From what i can see from that pic, it maybe the AAC valve socket

Edited to say, that you should be able to easily fit this with the plenum in situ, as you need to connect/disconnect it when setting up the idle

Uhmmm, Do you have to do something special to set the idle on this. I'm having the usual idle wobble problem of mine and we changed nearly everything but I was unaware that you have "connect/disconnect it when setting up the idle"?

There is a thread on here somewhere.

Something like that you disconnect the connector, and then set the idle to 950 or whatever, and then reconnect it. The revs should rise slightly, and then settle at the setting, i.e. 950rpm

Edited to say did you clean the so called "carbon" out of the throttle bodies? And did you adjust the stops on the throttle stops?
