Hi guys,

I have an issue with the sunroof on the r33. I went through the car wash(Only purchased it an hour ago), and suddenly had water dripping on my head.

So I then opened the sunroof, and then went to close it and it would stop half way. The motor tries to keep going but it just gets stuck.

Anyone have any ideas on what this could be? Cant really keep it open as it is, as it will be raining soon.

Also, the interior slide out bit seems to be loose, and not guided. Is this how it should be?

Thanks guys in advance.

Having a sunroof is awesome, I love it, but also blows at the same time...just another hole for water to leak through. Try checking/replacing the sunroof window seal to eliminate it leaking again. Check the the window guiding rails (on each side of the sunroof), for anything obstructing the rollers from moving. Maybe rusted, unlubricated, etc etc. Maybe having a look at the moving gears, maybe it's lost a tooth, therefore motor keeps winding but it aint moving, just stuff like that. Could be problem from ages and has damaged the interior slide pannel, as usually constructed with chip wood sheet, or something like that....im just ranting on...hope it makes sense to you owen. haha.

Damn, I cant even manually close it. This is not a good start :huh:

It seems to stop right when the two feet (The parts where the roof tilts at the axis) approach the little openings on the rails.

It does not stop as if it were a motor problem, or tooth, it seems to just suddenly stop as if it has hit something.

the sunroof runs on cables that corkscrew when the motor rotates..

Is the motor trying to rotate?

Could be that one of the cables is stuck - mine did a similar thing where a cable came out of it's grip and the sunroof wouldn't really move.. Ended up having to take the roof lining out, take the sunroof out and pull it apart and replace the cable with a spare one I picked up..

The feet that it slides on can break as well which will cause it to jam.. i've attached the service manual for it.. This was the same as my S2 sunroof..

Costs about $400 for the new feet I think.. Ring nissan.. My advice, pull it out of the car and than asses what is wrong with it - you can't fix anything with it in the car..

I agree with Links. The best thing to do would be to take it apart and try and find out what is wrong like that. It could be a whole heap of different things, so we couldn't tell you for sure just from your explanation. We'd have to see it for our selves. But good luck trying to fix it tho.

Yeh I have been looking at it, and it looks like it is snagging on the roof where there is a support?

Just wondering if the feet that push up are stuck in the upright position? Or close to it.

Another thing, When the sunroof is open(into the roof), I assume the up down button would not work at all??

i had the same problem in my R32, all i did is lubricate with a long nosel. but u have to clean it first, if it doesnt work, the only thing u can do is wen it get stuck halfway u open it with a button or push it back and then when closing push the screen with ur hand from the start to close, thats wat i did until i oiled it ;)

I had the same problem where the sunroof opens 1/4 way and then stops. Then when you press close, it won't close anymore. I had to press the close and push the sunroof back to it's original position to get it to work. For my solution, it was to replace the sunroof motor which took me a looooong while to find as no one sells a 2nd hand unit. I finally got the motor on e-bay and it's for the Silvia S14 model. Most of the parts that are on the R33 are identical to the S14. Got it and installed it. Now the sunroof works like a charm. As for the leak, it's just the glass seal. Replaced that easily as well.

I have tried to push it.. Its too damn solid.

It appears to stop at the guide links?? Which appear to be loose.

Am I able to remove it with it half open?

Is there any way to close it manually? (Its raining quite a bit).

FIXED!!!!!!!!!!!!!!

Took me 4 hours to rip the car apart, take the whole unit out (Myself I may add.. Tough job), Took all the rails out and found out it was a piece of filing/metal that was blocking one of the rails.

Thing was, it was between the two runners, so I could only get to it by taking the glass off.

Anyhow, off to the car wash... Its well over due!!!

Cheers guys.

      R32 GTS (RB20DE) Injectors Replacement

      Stock RB fuel pressure is near enough 43.5 psi, so the latency in that table at 31.6 will be close. You can see that 7 or 8 psi equates to about 0.4µs extra latency. So if you wanted to interpolate between the 31.6 and 39.9 psi values you could say you're going up about 2 psi out of those 8, so add about 0.1µs, which is barely worth talking about and is quite possibly wrong because ideally you would fix the latency while running at the appropriate conditions on the dyno, with a wideband sniffing its butt.

      The pressure, is what you set the fuel pressure to. If you have the factory fuel reg, you'll need to find the factory spec. I don't know it off the top of my head, but someone else might.

      Belt flex under throttle

      By MBS206 · Posted

      For others, what GTSBoy states here should be paid attention. Why? Well lots of people play with different engines, and they LOVE to change things like remove AC, or steering pumps etc, and it lends to them needing to move the tensioner too. You want your tensioner, particularly those that are sprung or hydraulically tensioned, to be the first thing after the harmonic balancer, or technically the "last" pulley in the chain. By saying last pulley, I mean look at the direction the crank spins when the engine is running, follow the belt from where the crank is pulling the belt FROM, and keep following that until you're between the last pulley/accessory on the belt and about to reach the crank again, this is the spot where you put the tensioner. This is the area that will always end up with slack. This is worked out exactly the same way for chains too, as the physics is the same for them. The crank pulley is where all the force to drag the belt around comes from. You will never ever get rid of the slack that appears, especially under load. The tensioners job is to keep the belt loose enough when stationary that there shouldn't be out of sync movement in slow movement, and then be tight enough when running, that the belt can't jump off any gear and get damaged. Too tight, bad things happen, too loose, bad things happen. Have a tensioner (mainly sprung/hydraulic one) in the wrong spot, it can't actually do anything about keeping the tension.

      It was gonna take much longer for the 440cc so I'd thought I'd risk it with the 550cc. They finally arrived and I couldn't wait any longer (I could but I was quite excited after 2 months) and installed them myself. Removed the old injectors, inserted the new and connected everything up. Before starting the car, I tuned the injector size from the factory 270cc to 550cc using Nistune.   This did some of the calculations automatically which catered for the TIM. The latency however did not seem to change. Deatschwerks have the tuning data available for each injector online, and I had a look at it. It has a table which relates to latency according to pressure and voltage (see below image). Nistune requires the 14v value, but I am unsure of which pressure value to look at (my lack of knowledge and experience have something to do with this). The highlighted value is close to my current latency which is 760µs. It is for 14v which makes sense, and the pressure is 31.6 Psi.   I still gave the car a test drive to see how it goes, and honestly it has never felt so powerful before (and some people say the RB20DE is very weak?). I really enjoyed the drive. Side note; The injectors are quite noisy, which someone mentioned before. This does not really bother me however. I will still ask my mechanic to have a look at it and perhaps ask a tuner to fine tune it if they have the knowledge.

      Also true. But imagine not wanting new injectors? Imagine wanting to use 30 year old injectors?
