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

      I've heard the Tomei USA head gaskets are decent if you want to o-ring the heads but otherwise not recommended.

      What brakes on R34 GTT(Europe)

      By GTSBoy · Posted

      The 296mm rotors are the R33 turbo brakes. The 310mm rotors are the R34 turbo brakes. The calipers are nearly the same, but not. They're the same caliper but the R34 caliper has longer legs so that it sits out far enough to go over the rotor. The pads are the same for both. When you say, "I bough tsome EBC"....did you just mean pads? Or rotors? 310mm rotors fit under 17" wheels. There may be some wheels without enough clearance though. I can't fit my fingers between the barrel of my wheel and the "corners" of my R34 calipers, but there is plenty of room behind the spokes. This is on Enkei RPF1. You can fit 324mm rotors inside a 17" wheel, but I'd be willing to bet that it would be close to impossible with the Nissan/Sumitomo caliper (using an adapter, of course), because the Sumitomo caliper is fatter than the Brembo caliper that is supposed to go on the 324mm rotors.

      Hi. Can someone tell me what brakes(and mainly WHERE) can i buy brakes on R34 GTT? I bought some EBC which SHOULD go on my car(i have GT but it has GTT brakes) but it does not fit, Brakes are "too" small(296mm) Are 310mm be good or? I have 17 inch wheel so no "big boys" but for me driving i just need one that fits and i can get here in EU/Czech.

      Hey. Very valuable information about pitwork, I will pay attention when buying any consumable parts 🙏 As for the carpets - I got a handful of information from nengun, from which it appears that indeed the carpets for the driver's side are OEM. They are not able to show me any pictures due to the long chain of different sales entities but after I place the order, as soon as the goods arrive at the nengun warehouse from which they will send the shipment to me they can send me photos and if my purchase differs from OEM I can immediately return it / cancel the purchase. I think I will give it a try 😉. Of course i'll let you know what's what as soon as i get them P.s. I know the topic is not relevant to the thread, but both nengun and amayama have these SICK 😍 trunk room lamps available. Do you know anyone who ordered them? I need to have one in my car
