Rb25det - Common Replaceables For Major Service

Hi guys,

A few weeks ago I acquired a series one R33 GTS-T. She's done 92,000km and as I do with every car this age and lacking a service history, first order of business is a timing belt change. Have purchased idler, tensioner, belt and a waterpump. As I'm not too familiar with these engines just yet, I thought I'd ask if there was anything else at the front of the engine worth replacing while I'm doing this job?

On the side, and excluding traditionally serviceable items (filters etc.), are there any other electrical/mechanical parts that commonly wear out on these engines? I belong to a Calibra forum and one of the first things we tell new members to replace is the coolant temperature and oxygen sensors, because they deteriorate around this age and have adverse effects on performance/economy. I'm looking for things like that, and manufacturer faults. I don't believe in "don't fix what isn't broken" so I have no issue spending money on preventative measures. Have read through the general maintenance FAQ and service schedule too...thanks for posting that as I have no user or workshop manual :D

Thanks in advance.

P.S. What I do believe in is "if something is broken it's a sign you need to modify it" :P

sounds like your mechanically mind and have things sorted out.... but you can also check:

-replace O2 sensor (as you mentioned)

-clean the AFM wire with brake cleaner

-check coil packs for hair line crack and use silicon to fill out - to reduce miss fires

-clean the idle control unit

-not engine related, but check caster rod bushes for leaks

I can upload the r33 service manual if you like? 23mb pdf file

Thanks for the suggestions, I was thinking along those lines. If it's not too much trouble and it hasn't already been uploaded, that would be fantastic.

Your R33 looks exactly like mine :D

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      I'm back from the dyno - again! I went looking for someone who knew LS's and had a roller dyno, to see how it shaped up compared to everything else and confirm the powerband really is peaking where Mr Mamo says it should. TLDR: The dyno result I got this time definitely had the shape of how it feels on the road and finally 'makes sense'. Also we had a bit more time to play with timing on the dyno, it turns out the common practice in LS is to lower the timing around peak torque and restore it to max after. So given a car was on the dyno and mostly dialled in already, it was time for tweaking. Luis at APS is definitely knowledgable when it came to this and had overlays ready to go and was happy to share. If you map out your cylinder airmass you start seeing graphs that look a LOT like the engine's torque curve. The good thing also is if you map out your timing curve when you're avoiding knock... this curve very much looks like the inverse of the airmass curve. The result? Well it's another 10.7kw/14hp kw from where I drove it in at. Pretty much everywhere, too. As to how much this car actually makes in Hub Dyno numbers, American Dyno numbers, or Mainline dyno numbers, I say I don't know and it's gone up ~25kw since I started tinkering lol. It IS interesting how the shorter ratio gears I have aren't scaled right on this dyno - 6840RPM is 199KMH, not 175KMH. I have also seen other printouts here with cars with less mods at much higher "kmh" for their RPM due Commodores having 3.45's or longer (!) rear diff ratios maxing out 4th gear which is the 1:1 gear on the T56. Does this matter? No, not really. The real answer is go to the strip and see what it traps, but: I guess I should have gone last Sunday...

      What brakes on R34 GTT(Europe)

      By GTSBoy · Posted

      310mm rotors will be avilable from Australia, Japan, and probably a few other places. Nothing for the front can be put on the back.

      The filter only filters down to a specific size. Add to that, the filter is AFTER the pump. So it means everything starts breaking your pump even if its being filtered out.

      Just like in being 14mm too small (296mm) makes it not fit, being 14mm too big (324mm) it also won't fit. You want to find the correct rotor.

      @GTSBoy Ok so that was the shops problem...they showed R33 rotors on R34 page and i did not know 296 do not fit(and are for R33) Yes i bought "kit" with rotors and pads. Pads are ok(i have GTT calipers front and rear). They have some 324mm but no 310mm. So i dont know if they would fit. I have 17inch LMGT4s So another question. Can i fit those in the rear or they are just "too" big for that?
