Hey Guys so i just picked up my N/A R32.

I'm looking at doing Oil and filter change, preferably everything, because there was no previous service histories,

Now just a few questions.

How common are the Rb20DE N/A R32 Manual ?

What kind of petrol do i fill it up with ?

Unleaded or Premium , does it say in the book ?

What Kind of Oil do i use ?

10-40w ?

Sorry Guys, Just need a breif explanation.

What are common problems to look out for ?

Does a GTST Gear box fit the NA Version ?

And what pipping sizing are the exhaust and will a GTST muffler fit on mine ?

cheers, sorry for all the noob questions.

recently bought one myself man.

mine came with a 2.5'' exhaust system, feels like i'm loosing a little power at the lower end, i'd go with a 2.25'' system for optimal performance.

As for juice, I've been filling up with premium since i got it, havn't run it on normal unleaded before... so not too sure there.

1: manual natro r32's are common. i'd say just as many manual versions as auto, if not more

2: 10w40 oil should be fine.

3: you could use 91 octane fuel, however my suggestion would be at least 94/95 octane (E10 should be fine for this), and 98 is preffered.

4: most common problem would be coil packs arcing out from old age (resulting in misfires)

5: gts-t gearbox will bolt to a natro. the gts-t box is a stronger box, but unless your box is stuffed i wouldn't waste the money.

6: gts-t exhaust should fit on without much hassle. as said above, if you go an aftermarket system i'd suggest a 2.25" system as said above.

I used to run my RB25DE on E10 95ron with advanced timing, never had any detonation (n matter how far I advanced the timing) used to run fine.

Would probably be OK on 91 with standard timing, but E10 95 is just as cheap and it's worth running the higher ignition timing for that little extra grunt. I actually felt the tiniest drop in performance switching to BP98 before adding a turbo, but have no figures to back it up (just felt less responsive).

Stupid question but how do you know your engine is pinging?

Thats not a stupid question haha, i was about to ask the same thing aswell.

Also, there is a fan that fan's the radiator , can i get rid of it ? and if so what do i replace it with ?

cheers, cause i see most tuned cars have slim line fans, but cause this fan is located on the block thought it worked diffrently, cheers.

You can hear pinging, like a quick flick of a tin can, or if it’s bad like a marble in a tin can... You can get knock warning devices, you can see your knock reading on SAFC and some after market management. The ecu also monitor's knock so you can feel it drop power/hesitate as well (providing all your sensors are connected and functioning).

The stock radiator/engine fan is called a clutch fan, in older age they tend to seize on a bit, make your car sound a bit like a falcon or hilux (windy revs) and steal a bit of power. You do need some sort of fan for your radiator, a good replacement is a temperature controlled electronic thermo fan, I have these on all my cars (inc twins behind a FMIC and a single 7” behind my R34 SMIC). They are noisy when they are on, but the motor is happier & quieter - plus I have lost 2 radiators and one water pump to seizing clutch fans in the past.

only bad pinging is audible. a lot of the time the car might be pinging and you won't hear it. on a stock ecu though, if the knock sensors are working properly it should retard the timing a bit to reduce pinging.

the stock clutch fans, when working properly, are the best option to use. they draw much more air than most thermo fans. there are plenty of high HP cars that still run them. people seem to think that thermos don't draw any power from the motor, but then add resistance to the alternator, which is run by the engine, so they still do drain a bit of power. if you do decide to run a thermo setup then my advice is to use the setup off a car that has them from factory, such as late model falcons, or fwd cars. these are often much more powerful than aftermarket ones, and the fact that they come with ready made shrouds you know that they are going to do the job well.

      Mistakes were made, my R34 Story

      Yup. You can get creative and make a sort of "bracket" with cable ties. Put 2 around the sender with a third passing underneath them strapped down against the sender. Then that third one is able to be passed through some hole at right angles to the orientation of the sender. Or some variation on the theme. Yes.... ummm, with caveats? I mean, the sender is BSP and you would likely have AN stuff on the hose, so yes, there would be the adapter you mention. But the block end will either be 1/8 NPT if that thread is still OK in there, or you can drill and tap it out to 1/4 BSP or NPT and use appropriate adapter there. As it stands, your mention of 1/8 BSPT male seems... wrong for the 1/8 NPT female it has to go into. The hose will be better, because even with the bush, the mass of the sender will be "hanging" off a hard threaded connection and will add some stress/strain to that. It might fail in the future. The hose eliminates almost all such risk - but adds in several more threaded connections to leak from! It really should be tapered, but it looks very long in that photo with no taper visible. If you have it in hand you should be able to see if it tapered or not. There technically is no possibility of a mechanical seal with a parallel male in a parallel female, so it is hard to believe that it is parallel male, but weirder things have happened. Maybe it's meant to seat on some surface when screwed in on the original installation? Anyway, at that thread size, parallel in parallel, with tape and goop, will seal just fine.

      How do you propose I cable tie this: To something securely? Is it really just a case of finding a couple of holes and ziptying it there so it never goes flying or starts dangling around, more or less? Then run a 1/8 BSP Female to [hose adapter of choice?/AN?] and then the opposing fitting at the bush-into-oil-block end? being the hose-into-realistically likely a 1/8 BSPT male) Is this going to provide any real benefit over using a stainless/steel 1/4 to 1/8 BSPT reducing bush? I am making the assumption the OEM sender is BSPT not BSPP/BSP

      Jacks that fit under GTR lips that can reach the subframe?

      I fashioned a ramp out of a couple of pieces of 140x35 lumber, to get the bumper up slightly, and then one of these is what I use

      I wouldn't worry about dissimilar metal corrosion, should you just buy/make a steel replacement. There will be thread tape and sealant compound between the metals. The few little spots where they touch each other will be deep inside the joint, unable to get wet. And the alloy block is much much larger than a small steel fitting, so there is plenty of "sacrificial" capacity there. Any bush you put in there will be dissimilar anyway. Either steel or brass. Maybe stainless. All of them are different to the other parts in the chain. But what I said above still applies.

      You are all good then, I didn't realise the port was in a part you can (have!) remove. Just pull the broken part out, clean it and the threads should be fine. Yes, the whole point about remote mounting is it takes almost all of the vibration out via the flexible hose. You just need a convenient chassis point and a cable tie or 3.
