First thing to do:

timing belt, water pump

Reason why?

Most imports have had their clock wound back, or clusters have been replaced

Then:

  1. Full exhaust (just get 2nd hand) ~$500
  2. Intercooler of some sort, even a R34 GT-t side mount $100
  3. Hit up Toshi for a socketed stock ECU with a new ROM tuned for AU 98 Octane fuel ~$350
  4. Turbotech MBC 0.8bar ~$30
  5. Fry tyres ~Priceless

The only thing I would add to that is a new fuel pump. The second worst thing that can happen to a 20 year old car after a shredded timing belt, is a failng fuel pump.

Johnny's list is solid.

If you want to go further than that you will find out that everything on the R33 has been sized just right for factory output plus a little more. Figure out what your ultimate power goal is and work back from there to see what needs to be done.

This times 1000!!! I spent about 20 grand on mine when I bought it. Thinking back now could of saved a lot of time and MONEY by researching more. I would of saved about 8 grand and over a year of time for a better result.

Ha ha. I also would have saved a bucket load. 3 turbo's before i reached my power goal,

Part of doing timing belt and waterpump is replacing cam seals. They will leak, they cost less than 10 bicks each and you have to take timing belt off to do them, so do then at same time.

Just a thought, see if you can pick up an rb20det turbo actuator and swap it with the rb25 turbo actuator. I've seen the individual actuators sell for around $50. The rb25 turbo actuator is set on roughly 7 psi whereas the rb20 turbo actuator is set on 10 psi.

Just a thought anyway.

Agreed, mine leaked at about 160k and they were rock hard. Chalk that up as number 6 on the list of things the dropkick knuckledraggers I took it to for the 100k service didn't do properly.

      Shifting questions

      By DRoc81 · Posted

      This was a huge help.  We followed the steps,  although shifting into 2nd was actually into 3rd for us,  and 1st was into 2nd ( steps 9 and 11) .  The long flash was the 4th flash.  So shift solenoid A is possibly the culprit.  Is this inside the transmission itself? Or is it accessible by just front the pan? Or is it bolted to the outside of the transmission?  Thanos for your help everyone

      Can you enlighten me on your best practice regarding these hoses? I don't wanna make the same mistake if you already got a better solution.

      I have some silicon hoses already, for example engine to watercooler. But yeah, I get the sentiment. The lower intercooler silicon hose is drippy too, despite not being very old. Does anyone except Nismo make these same lines out of rubber? Long term I think they'd be the better replacement, especially since the car won't live as hard a life anymore as in the past nor be driven as often.

      I know most issues are just age related. But for example the turbo oil drains, there is dash adapters for these and you can just make a braided teflon line for them and (probably) never have them leak again. Also not terribly expensive. Can you even get the factory hardlines from new? Or are they repairable if they break?

      I know it'd be much much easier with the tool. I hope I can find one that won't take 3 weeks to get to me an isn't a "Asian models kit" that has tons of (to me) useless adapters for a load of cash.   It's a summer project/fun car. I do wanna enjoy it, without endless downtime over and over. So yeah I would even go and buy an engine crane + stand to save myself the trouble of hard to reach or unreachable places going bad later on. Would also be a good opportunity to put on a Fluidamper, renew the mains seals and stuff like that. I have some money on the side that I can use for that, what I wouldn't want to or be able to do is let everything be done by a shop or have my engine completely rebuild right now. I intend to do most of the "doable" jobs myself. Pulling an engine can't be that hard, can it?
