I'm looking at buyign my first skyline.

As advertised....GTS R33 1994 (non turbo)

I was under the impression that _ALL_ GTS R33 had RB25.

This car has R33 stamped all under the bonnet, but is also stamped RB20. Does anyone know if this is the original motor, or if it is a replacement (dont ask me why ud put a smaller one in)?? Also is there a simple visual difference between the RB20 and RB25 that is easy to pick?

Thanks in advance

yes, they were available with only RB20DE.. or was it even RB20E - the japanese "taxi" spec, or close to it..

Well the RB25 will have Nissan 2500 on the cam cover, the RB20 won't.. you'll also notice that the RB25det has "kinks" at the back of the cam covers.. the RB20 doesn't. Note that both of those items may be swapped quite easily... check the engine number, down bottom left the block (will need torch).. starts with rb20.. it's an rb20..

Ok ok, thanks

So does anyone know if there are other differences between

the japanese "taxi" spec R33 RB20

and the "normal" R33 RB25

Clearly its 0.5 Lt bigger, but are there differneces to the gearbox / diffs / cooling ... that i should know about. Seems to be a common reported problem that R32 RB20's are crap as they aparently over heat, is that a known problem of the R33 RB20?

Ok, R33 GTS has the RB20E - SOHC head, good for 100kw or so. R33 GTS25 (note the '25') has the RB25DE, 147kw in type S form.

If you look at the VIN no on the firewall the GTS is HR33... whereas the GTS25 (and 25T) is ER33 (or ECR33 for HICAS equipped models).

There are a huge number of GTS's in NZ, but apparently not so many in Aussie from what I've heard.

As for overheating - not something I've heard of, I would guess that the 2.0L has to work harder as it is dragging round a whale designed for a 2.5L engine. However the 2.0L engine is quite a bit smaller than the 2.5, so the engine bay looks pretty empty and therefore cooling is better.

Gearboxes etc - the gearbox and diff type numbers are also listed on the firewall plate. I believe that the GTS and GTS25's are different in this respect, but not certain, if I remember I'll check what mine has and post it up.

this version of the rb20, as mentioned, is absolutely GUTLESS

remember that this engine makes less power than a locally-delivered R31 and in the heavy R33 chassis

yeah its a skyline, and looks a treat too, but if you are thinking you will get a little bit of power with this car you are wrong. don't be surprised if this car gets beaten by a stock pulsar at the "traffic light grand pirx"...

Wow, I rememba tha first time I drove my baby home (a few months ago hehehe), I was so excited I spent an hour in the driveway just lookin at the body, engine and interior. :boinkcar:

I hope your 'line brings you as much joy as mine does fer me :(

hmmm, only 2L engine huh? I guess if u drive around an stick to the speed limit ppl won't be any wiser. U can be like "psshhh" I got a "skyline" it ain't worth the effort to race you! :talk2hand

besides, ur insurance is prolly HEAPS betta then mine

Its listed as a HR33, so he's listed it wrong?

Thanks for your reply boj

Im totally in the dark, don't know a thing re skylines, so im learning :P Sorry for my stupidity :P

Err, that's an interesting looking car. HR33 - yup, sounds like he has either got it wrong (H=2.0L engine, should be E for the 2.5), or it is really a GTS and he is trying to pass it off as a turbo. Ask for a pic of the engine bay/vin plate.

Also not so sure about it being a 96 - it has a S1 front, AFAIK all post 96 cars have the S2 front end. It does have a S2 wing, though that is a relatively common mod for S1 owners, also some '95 cars have S2 wings (and other S2 bits) from the factory and are known as S1.5.

Definitely ask for the VIN number and post it up here (or PM me), then either myself or someone else can use FAST to check out exactly what it is for ya.

      Neil's R33 Gts-t Build

      Then today, I went to visit a man with an r33 hat Peter and Road and Race sorted the alignment. As it is being set up for general track/hillclimbs etc it has a heap of caster (7o), less camber than I am used to (1o front and 2o rear, as the caster looks after that in turns without the braking downsides), 3mm front toe out and 0 toe rear. Will see how that goes and track tyre wear to see if it does need more camber, but adjsustment is also limited with nismo arms and adjustable bushes at only 1 end. It does have a bent inner tie rod on the driver's side front but as it came up within spec I'll just leave that as is. So, that is getting close to my chapter of this story....could of tidy ups then a shakedown in early October before it finds a new home.

      So, it went to Unigroup for a run in and tune on Friday, everything went (generally) well. In terms of fixes, the engine was good and there were no leaks. It needed plugs (I hadn't checked them because the coil pack cover was on a new engine and I couldn't imagine they weren't new.....but turns out the temporary plugs to just keep it sealed up were in there.....new plugs gapped to 0.8 and it was fine from there. Also, there was a little preload on the clutch slave which caused some slip. I haven't had the box off so I don't know what the clutch looks like; my guess it is brand new and the pedal had not been adjusted....backed that off a bit and it held fine. Last thing will have Dose crying....the idle especially when cold is a bit difficult between the cams, forward plenum, atmo blow off valve and an 80s air management system. It is fine when hot but a little uneven when cold, will see if I can sort or at least improve that one cold morning. Other than that, tuning went fine. It made 245 but was pulled back to 227 which 2 opportunities to improve in future. 1. The factory CAS is not great and was jumping around at high RPM, so Mark took 2 degrees out up top (that is why it stops making power and lost 20kw). Very safe this way and the extra power is available but will require a more modern ECU and better cam (or even better crank) sensor 2. The 2871 in factory housings is very big for a low mount, and the internal wastegate is too small, so it was creeping from mid range all the way to redline....the duty cycle on the boost controller is turned down a little for safety. That is much harder to fix, it would need a large external gate and that would require a whole bunch of other changes, so it will go as it is for now. It feels nice and healthy and safe, so should be good for about a billion laps like this.

      Slight brake pedal stutter after new pads

      By Duncan · Posted

      what sort of caliper are they? If they are a slider and you gave everything a good clean, you might need to regrease the pins. My guess though is they will come good after some abuse as suggested above
