Hi fellow stagea owners I NEED YOUR HELP!!! My stagea was steaming up alot and had a bad smell coming in from the vents then i noticed a wet patch on my passenger footwell OH NO! water was coming in from up in the well!! Im sure its the heater matrix which has gone, so im wondering if any of you guys can tell me do i need a stagea matrix or will any of the skyline or any other nissan ones fit and if so is it a huge job to fit it or can anyone have ago at it?

Any help will be gratefully apprectiated thanks.

hey your heater core has gone by the sounds of it

go into the engine bay and disconnect the hose that goes into the firewall above the turbo heatshield, just under around bonnet height. probbaly best if I take a photo to show it.

I have heard you can use a 300zx heater core, I ordered one months ago for $220 and have never seen it (better check my visa card actually) so i cant confirm.

My local radiator peeps have quoted me $450 to rip out the dash and put back together, plus the core which is $500 from japan with new brass fittings

it's a biatch of a job!

i took mine out of my R33, and even with no intentions of putting the dash back in, it was quite a job.

you basically have to remove the entire dash, and everything in the way of the core...

dunno about a skyline one fitting, although the dash is a very different shape, but heater cores are pretty much the same regardless of make or model aren't they? You will only be restricted by inlet/outlet size, and what will actually fit in the hole left by the other one.

as for it being a hard job? To be honest, not really. It is a long, involved and fiddly job, but there is nothing that is very technically demanding about it. Same as everything else, if you take your time, pay close attention to how things come apart, and bag and label everything you take off, then you will be fine. I do recomend that you have a digital camera on hand to take photo's as you go - this can be an invaluable tool when it comes time to reassemble.

Ditto on what Stinky Rooster said.

I've done this on an R31 Skyline and VC Commodore, except had A3 pieces of paper

on the garage floor with bolts laid out in position relative to the dash position.

Took 5-6hrs taking my time on a Saturday with a few ciggie/drink breaks in between.

Do it yourself take your time and save $$$$.

Looked into this and was told by a well known Skyline tuner in the UK that the heater Matrix will come out into the passenger footwell. They reackon no more than a couple of hours to change !

Don't shoot the messenger as I have not done it myself yet.

YEAH, I have heard that in an auto you can get to the heater core thru the glovebox area, but need to disconnect air conditioning and regass afterwards.

yes i can say taking the dash apart is a killer of a job, finding all those damn screws and clips is a job in itself :rofl: Good luck, dont forget there is a couple of screws in the demister vents and they are hard to see unless u look through from the outside of the windscreen. These 2 bolts prevented me removing the dash for a day as i couldnt work out for the life of me what was holding it on

    • The time is always correct. Only the date is wrong. It currently thinks it is January 19. Tomorrow it will say it is January 20. The date and time are ( should be ! ) retrieved from the GPS navigation system.
    • Buy yourself a set of easy outs. See if they will get a good bite in and unthread it.   Very very lucky the whole sender didn't let go while on the track and cost you a motor!
    • Well GTSBoy, prepare yourself further. I did a track day with 1/2 a day prep on Friday, inpromptu. The good news is that I got home, and didn't drive the car into a wall. Everything seemed mostly okay. The car was even a little faster than it was last time. I also got to get some good datalog data too. I also noticed a tiny bit of knock which was (luckily?) recorded. All I know is the knock sensors got recalibrated.... and are notorious for false knock. So I don't know if they are too sensitive, not sensitive enough... or some other third option. But I reduced timing anyway. It wasn't every pull through the session either. Think along the lines of -1 degree of timing for say, three instances while at the top of 4th in a 20 minute all-hot-lap session. Unfortunately at the end of session 2... I noticed a little oil. I borrowed some jack stands and a jack and took a look under there, but as is often the case, messing around with it kinda half cleaned it up, it was not conclusive where it was coming from. I decided to give it another go and see how it was. The amount of oil was maybe one/two small drops. I did another 20 minute session and car went well, and I was just starting to get into it and not be terrified of driving on track. I pulled over and checked in the pits and saw this: This is where I called it, packed up and went home as I live ~20 min from the track with a VERY VERY CLOSE EYE on Oil Pressure on the way home. The volume wasn't much but you never know. I checked it today when I had my own space/tools/time to find out what was going on, wanted to clean it up, run the car and see if any of the fittings from around the oil filter were causing it. I have like.. 5 fittings there, so I suspected one was (hopefully?) the culprit. It became immediately apparent as soon as I looked around more closely. 795d266d-a034-4b8c-89c9-d83860f5d00a.mp4       This is the R34 GTT oil sender connected via an adapter to an oil cooler block I have installed which runs AN lines to my cooler (and back). There's also an oil temp sensor on top.  Just after that video, I attempted to unthread the sensor to see if it's loose/worn and it disintegrated in my hand. So yes. I am glad I noticed that oil because it would appear that complete and utter catastrophic engine failure was about 1 second of engine runtime away. I did try to drill the fitting out, and only succeeded in drilling the middle hole much larger and now there's a... smooth hole in there with what looks like a damn sleeve still incredibly tight in there. Not really sure how to proceed from here. My options: 1) Find someone who can remove the stuck fitting, and use a steel adapter so it won't fatigue? (Female BSPT for the R34 sender to 1/8NPT male - HARD to find). IF it isn't possible to remove - Buy a new block ($320) and have someone tap a new 1/8NPT in the top of it ($????) and hope the steel adapter works better. 2) Buy a new block and give up on the OEM pressure sender for the dash entirely, and use the supplied 1/8 NPT for the oil temp sender. Having the oil pressure read 0 in the dash with the warning lamp will give me a lot of anxiety driving around. I do have the actual GM sensor/sender working, but it needs OBD2 as a gauge. If I'm datalogging I don't actually have a readout of what the gauge is currently displaying. 3) Other? Find a new location for the OEM sender? Though I don't know of anywhere that will work. I also don't know if a steel adapter is actually functionally smart here. It's clearly leveraged itself through vibration of the motor and snapped in half. This doesn't seem like a setup a smart person would replicate given the weight of the OEM sender. Still pretty happy being lucky for once and seeing this at the absolute last moment before bye bye motor in a big way, even if an adapter is apparently 6 weeks+ delivery and I have no way to free the current stuck/potentially destroyed threads in the current oil block.
