I hope someone out there can help me. I've got a '93 R33 GTS25 which need new front pads. I'm looking at EBC pads and can't find the actual size I need. EBC have two sizes listed; DP1082 and 1046 but without pulling my old ones out and physically measuring them they can't tell me what I need. My car is not the 'S type' and is still bog standard brake wise. If anyone has replaced their front pads in a '93 and can remember the product code and brand I might be able to match them up. Thanks.

As far as I'm aware all the R33 non turbos have the same brakes, but I'm not 100% sure though.

I have a R33 GTS25 non type s and my brakes are 155mm long from tip to tip and have a width of 50mm.

So I hope thats of some help.

sorry for offtopic: but what exactly is the S type?

Repco or Autobarn wud usually have a book on the fitment wudnt they?

Type S, has a few standard extras, LSD, an extra few kw at the fly wheel, a different rear muffler, and a rear sway bar, well my friends one has anyway, and maybe a couple of extra things I have over looked.

Thanks everyone. The difference between the two pads I've been quoted on is minimal, both sets are 155 mm long and 17 mm, the width varies. One set is 53 mm wide the other is 49 mm. I know its only a small variation and the pads themselves are the same profile other than the width, just needed to know what difference it would make.

I guess the thicker ones wud clamp reasonably earlier than the thinner ones.

In the end they'd wear down anyway - so I'd say if the thicker ones fit then go for them, you'd

get more life out of them as well i am assuming.

skyla: thnx, I guess I "might" have a type S - stock exhaust has a little flap thing which I am curious about.

That little flap is meant to be attached to a cable to allow u to open up the exhaust fulli. Its meant to open up at high revs and then close againt at lower revs for a more quieter note. Im yet to find a car that actualli has that cable but me and my dad were thinkin of somehow creatin a mechanism that opens up that second exhaust route at high revs to give a much better sound. In the end we couldnt be bothered so i just slapped a magna flow on instead.

Got the flap, the cable and the actuator on mine. Actuator is located inside the LH rear gaurd, below/in front of where the jack lives. Not sure what RPM level it activates at - I think I read > 4000 rpm somewhere?

yeah, i have it on mine also - when i chnaged to a 2.5" system i just left the cable in place where it once was and zip tied it outta the way - lol

and i don't know if my HICAS is locked - i am yet to see the light conme one (except when starting car of course) i assume it's locked - how cna i tell?

And about the LSD - when i do a burnout i get both wheels smoking :rant: but whats an official way to determine if your has it?

yup mine has the cable to open the flap too - I have yet to see it open though (cos I'm always

driving when it opens up I guess :rant:)

gatty: You can tell that your hicas is locked or not by doing a diagnostic (do a search), you can actually see the rear wheels move when your stationary.

Or when you drive, particularly around a roundabout, you can feel the rear end of the

car running sideways, it feels sort of drifty but obviously not on such an angle.

Dont quote me on any of this :) but from what I gather...

An LSD (limited slip diff) will let both wheels spin at different speeds, but it will just limit the amount of difference between them. So basically when you go around a corner, the

inside wheel will spin slower as it has less distance to travel.

I dont think a burnout is the correct way to determine that both wheels are spinning at

the same speeds. But if your wheels are spinning at the same speeds around a corner

(its most probably a locked diff) the inside wheel will chirp.

This is good for dragging, drifting and other straight line stuff ( I am not sure what is

appropiate for track work) But for street use the stcok LSD shud be fine.

      As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year.

      I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.

      Skyline v36 350GT sedan hunting on idle

      By Robot · Posted

      Hi,  Just joined the forum so I could share my "fix" of this problem. Might be of use to someone. Had the same hunting at idle issue on my V36 with VQ35HR engine after swapping the engine because the original one got overheated.  While changing the engine I made the mistake of cleaning the throttle bodies and tried all the tricks i could find to do a throttle relearn with no luck. Gave in and took it to a shop and they couldn't sort it. Then took it to my local Nissan dealership and they couldn't get it to idle properly. They said I'd need to replace the throttle bodies and the ecu probably costing more than the car is worth. So I had the idea of replacing the carbon I cleaned out with a thin layer of super glue and it's back to normal idle now. Bit rough but saved the car from the wreckers 🤣

      After my last update, I went ahead with cleaning and restoring the entire fuel system. This included removing the tank and cleaning it with the Beyond Balistics solution, power washing it multiple times, drying it thoroughly, rinsing with IPA, drying again with heat gun and compressed air. Also, cleaning out the lines, fuel rail, and replacing the fuel pump with an OEM-style one. During the cleaning process, I replaced several hoses - including the breather hose on the fuel tank, which turned out to be the cause of the earlier fuel leak. This is what the old fuel filter looked like: Fuel tank before cleaning: Dirty Fuel Tank.mp4   Fuel tank after cleaning (some staining remains): Clean Fuel Tank.mp4 Both the OEM 270cc and new DeatschWerks 550cc injectors were cleaned professionally by a shop. Before reassembling everything, I tested the fuel flow by running the pump output into a container at the fuel filter location - flow looked good. I then fitted the new fuel filter and reassembled the rest of the system. Fuel Flow Test.mp4 Test 1 - 550cc injectors Ran the new fuel pump with its supplied diagonal strainer (different from OEM’s flat strainer) and my 550cc injectors using the same resized-injector map I had successfully used before. At first, it idled roughly and stalled when I applied throttle. Checked the spark plugs and found that they were fouled with carbon (likely from the earlier overly rich running when the injectors were clogged). After cleaning the plugs, the car started fine. However, it would only idle for 30–60 seconds before stalling, and while driving it would feel like a “fuel cut” after a few seconds - though it wouldn’t fully stall. Test 2 – Strainer swap Suspecting the diagonal strainer might not be reaching the tank bottom, I swapped it for the original flat strainer and filled the tank with ~45L of fuel. The issue persisted exactly the same. Test 3 – OEM injectors To eliminate tuning variables, I reinstalled the OEM 270cc injectors and reverted to the original map. Cleaned the spark plugs again just in-case. The stalling and “fuel cut” still remained.   At this stage, I suspect an intermittent power or connection fault at the fuel pump hanger, caused during the cleaning process. This has led me to look into getting Frenchy’s fuel hanger and replacing the unit entirely. TL;DR: Cleaned and restored the fuel system (tank, lines, rail, pump). Tested 550cc injectors with the same resized-injector map as before, but the car stalls at idle and experiences what feels like “fuel cut” after a few seconds of driving. Swapped back to OEM injectors with original map to rule out tuning, but the issue persists. Now suspecting an intermittent power or connection fault at the fuel pump hanger, possibly cause by the cleaning process.
