Hi y'all

My bro finally joined the skyline club!

It's an '95 R33 series 1

He wants a drift car out of it and has to rebuild it cos piston rings are gone

My question is what would you suggest he does whilst the engine is apart? He's a mechanic and all the work will be done at home... He wants to spend about $2-3K

The front mount has been installed but that's about it at this stage, pretty stock...

Thanks heaps

Forged pistons, RB26 or just balance and shot peen stock rods, Nissan or ACL bearings, Metal head gasket, N1 oil pump with Billet gears if you dont want to go a good oil pump, Head drain/return, IF he's building a dedicated drift car id go a larger baffled sump ASR or Hi Energy.

What power figures is he after also how reliable does he want the setup to be?

1> Don't drift it on the stock turbo. He will want more power, he will turn the boost up, the turbo will shit itself, he will be unhappy.

2> Don't drift it on the standard ECU. He will want more power, he will turn the boost up. The ECU will crack the shits, he will be unhappy.

That's already more than $3k right there. Double the budget, then double it again.

People are out there drifting with RB20e motors in there cars, so a standard RB25DET should be fine. More power is great, but I guess it also shows that handling setup can and is just as important as power. By all means though get some more if he can because, why not!!!!!

Head studs, oil pump collar, oil pump, oil restrictor in head and enlarge block drains.

Extended/baffled sump with an oil cooler. Then you should be set.

Stocker 25's go great. Dont worry about power yet. Get the suspension gear done (diff,castor,camber,coilovers,rack spacers) then worry about hp.

Basically. Get the cooling spot on, Oil control and reliability spot on, Suspension and steering spot on then when you can confidently drive it in the red all day long (7,000rpm) and pull big entrys.. then you put more power into it. Your coight will pucker when you're 3rd pinned about to initiate your entry at winton before the last s bends. Thats without much power.

In terms of the factory RB25DET tune, is it considered "safe" for drifting/track work/in general? Obviously not maximized for power or apparently ralative fuel economy but aside from that.

Stock tune with the engine in stock form and it will do fine. From memory i think it runs a little rich so not a bad thing, correct me if i'm wrong.

I drifted mine for over a year, factory tune with just a front mount and turbo back.

I'd never go to the track with a stock ecu on a RB25DET thats been boosted. I melted a couple pistons on the street with my old RB25 running 12psi. Put in an unopened engine with an ecu and a good tune been making 300+kw for around 6 years and ringed the absolute neck of the RB and it hasnt even had a missfire.

A vehicles tune is a make or break sort of thing.

      Replacing turbo water line - any recommendations or advice?

      By jtha7 · Posted

      Hi all, Restoring r33 series 1 rb25det. All the heater hoses were on their way out, have replaced them and put it all back together. After testing I noticed a small leak from behind the head on the actual metal water line to the turbo when cars warm. I tried running a longer hose over it but it kept leaking...   I am about to take the (stock) manifold off again😔 to change the water line does any one have any lines they recommend? I was looking at Aeroflow Turbo Oil & Water Line Set but not sure what everyone else recommends. Car is completely stock but want to upgrade turbo eventually. it looks like ill have to disconnect a lot just to replace these lines so if there's anything else recommended to do please let me know. Thank you in advance!

      From memory, on the R33 GTSt at least, while everyone says "It's not adjustable", I found when I changed clutches in mine, it just needed a small adjustment on the rod length. But be very wary here, as you could end up trying to push the pushrod in the master too far, or blowing out the slave.   Most likely though, if the master/slave isn't bypassing internally or leaking out, then the throw out is the wrong height compared to the fingers on the clutch, so when it moves to disengage the clutch, it isn't 100% disengaged. You can check part of this out too by jacking the car up, having the engine running, put your foot on the clutch and try to engage 1st gear. If it goes in pretty easy (Compared to the ground) and/or the wheels start turning a fair bit and it takes a bit too much brake pedal to bring them back to a stop, this is likely the issue.  I'm not sure if you can adjust the height of the forks etc in these though, it's been that long since I've touched any RB gearbox.

      That's all good, I thought I was missing some interesting feature! Maybe @PranK can double check if that is something that is meant to be operating or not.

      I hope that is not something that bad. From what i remember he said that only first gear is "hard" to get in and that he has couple of ideas what to try next but idk 😕  hope it is not gearbox out. I will let you know.

      If it's not the hydraulics, it is probably gearbox back out. Usually as per @Duncan's post, or otherwise associated with not getting the throwout fork positioned correctly. All the way up to catastrophically bolting shit back together without it being aligned properly and wrecking the clutch/input shaft/flywheel/something else.
