Hey guys,

Servicing my car soonish, i need to replace the timing belt mainly because i dont know when it was last done and better to be safe than sorry really.

Is there anything thats important to do on a 32 GTS-4 w/ RB20det while im changing the timing belt? I just remember something about changing the water pumps on the 34's at the same time due to the accessability of it or something.

Anything similar?

Obviously ill be doing plugs and such at the same time as the basic stuff just wondering if there was something else i should be aware of. Any input helpful guys.

Cheers,

Greg.

should say on your engine cover. Mine says 75000, and seeing as the previous owner didnt know if it was done by the owner before him im assuming that was the last time it was done.

because mines on 165000 now i figured i might as well just change it, better safe than sorry.

ive had mixed opinions about using a different timing belt. The fact is how different can it really be? Is my car reallllly operatin at over 5k rpm at all times that it needs one?

I just really think theres no point.

On a side note i was gonna do all the seals in the first place, comes in the timing belt kit. I dont really know why anyone buys a belt on its own.

Gday

just changed the timing belt myself on my R33 (Rb25DET)

Its not as complecated as you think

the RB25 and RB20 front ends are pretty similar so u shouldnt have a problem

the only problem ou might have is removing the harmonic balancer, which u need a puller for, but is fairly straightforward

make sure when the cover is off that you replace the TENSIONER and IDLER. Theres no point changing your belt just to have a bearing seize 2000 km later

The idler can be a little expensive (around 200 mark), with the tensioner around 120. no idea why its like that but hey it is lol

yeh and when you go to take a plug off you will probably damage a coil.. peice of shit things haha

but yeh as others of mentioned.. 100K the belt should be done by, do tensioner bearing and cam crank seals otherwise it makes it alot harder to do it twice, waterpumps shit themselves on 20s about 130 thousand kms and if your puln plugs out unless they are irridiums I would be replacing them and set ur plug gap at .8 but its one of those things.. where do you draw the line how far you go through? Coolant should be done every 30 thousand so its probably in need of that as well and all those heater hoses under the intake manifold will need attention especially seeing January/Feburary is comn up as thats usually when it starts getn hot

$500 bucks for a 20? i sold my last one for 200 with a good turbo and seen many others but they are pretty much needing the same attention anyway

      S1 rb25/s14 starting problem

      By 25zenki · Posted

      Maf is a question mark but TPS  I have set at 0.47, the fact that I’m getting proper voltage range out of it with the key on leads me to believe it’s functioning properly. I’m getting proper voltages on basically everything. I still need to look up voltage ranges for z32 maf and test that

      S1 rb25/s14 starting problem

      Honestly no not at all, but it’s a very basic tune, it’s stock injectors q45 tps and z32 maf. Other than that it’s a completely stock base map. The file is from nistune and from my understanding if it was tune related I would be able to unplug maf and tps and it would still start even if it was a really shitty start. I have tried starting it with coolant temp, maf, and tps unplugged none of those 3 togethor or individually changes anything

      What does it look like with highway driving? And yes, I had a similar thought as Duncan. It looks quite similar in my Stagea and I have made myself accept it as normal. Might have to look into it some day   Highway gets as low as 10l/100km on my end so I'm not as worried about it being a mechanical issue. More likely just the tune on the haltech.

      RH9 R32 GTR Build Thread

      By OST Micah · Posted

      While I was waiting for the new parts to come in for the charge pipe and radiator I decided to do some turbo modification. The drive pressure (exhaust backpressure) was a lot higher that I thought it should be. For 32lbs of boost drive was 55lbs. The turbine housing is a 1.10AR and my turbo builder has suggested to go to a 1.25AR. To test if a larger AR would do anything to reduce drive pressure AND not spend any money I decided to hog out the divider in my current housing. I removed it from the inlet and the whole way through the housing.  After reassembly and testing it doesn't look like this modification did anything for reducing drive pressure or requiring more fuel (making more power). Oh well, it was worth a shot. We'll get some data at the track if it makes it past the 60ft. I also machined a $7 shift knob off Amazon to fit my Stillway shifter since I didn't like the Stillway shift knob. Next on the list was the radiator replacement and fabrication of a new intercooler tube that had no silicon coupler. No pictures of this - I was short on time each night after work to get this done and didn't stop to take pictures.  Next was to get the clutch disks out and replaced. Previously when installing the dogbox I had ordered a set of the same sintered iron disks I had been running because I switched to the 26-spline input shaft. I thought it was odd that they didn't have any markings or brand name on them like all my old disks had but installed them anyway. At the track I could not get the clutch to lock up using my normal strategies. After two track nights I reached out to the clutch manufacturer and ask their thoughts. They said they had to switch the material out because they were having trouble getting the original material and that this new material would not take to being slipped very well.  So out with the first set of 26-spline disks and in with the correct material 26-spline disks. While I had the trans out I added an inspection/service hole. I've wanted one of these for a while. Now I can have a look at things and change the front cover shimming when needed (clutch wear). I hustled and got the clutch change done in a few hours on a Saturday. Hopped in the car and drove home. On the way home I did a 1-3 pull. When shifting from 2nd to 3rd the core plug in the back of the cylinder head popped out and dumped all the coolant. Thankfully I was only 30 seconds from home and coasted it there. Datalog showed nothing unusual and 2.5psi of coolant pressure. That plug has been in there since 1992 but I guess it worked its way out. Pulled the trans AGAIN and replaced the plug, JB welded it in, and made a brace. Also deleted the head drain I had added in during the bearing issue fiasco.  I am currently changing my boost control plumbing to make it cleaner. After that is done I'll make another attempt at getting past the 60.
