Building a reliable R33 Skyline

Hi guys. I want to build my skyline into a reliable track/street car. It is not my daily, but I still want it to be as reliable as possible.

At the moment it has a 3" turbo back exhaust, spitfire coil packs, hks coilovers, return flow fmic and a ebc running 10psi and upgraded radiator with a gktech fan.

I run Penrite Racing 10w-40 10 tenths engine oil and change every 5,000km.

I have heard some issues with the rb25 is the oil pump, needs a crank collar. Can this be done without removing the crankshaft from the engine, pretty sure you have to machine it though.

Oil restrictors I have heard from research on here are essential too as well as a head drain kit and rb26 rocker covers.

What else should I look at doing to make it a reliable package. Also is this stuff required if my plan is to go to 250rwkw running a Link G4+ with a Kinguawa low mount turbo?

Thanks guys, please leave details and no sarcasm.

None of that is required. Fit your ecu, bigger injectors and turbo, retune and enjoy. 250rwkw is a walk in the park for an rb25. You'll need a better fuel pump if you don't already have one. Walbro 255 for that sort of power will be fine.

A mate of mine blew his engine from a failed oil pump at the track because he was on the limiter for a couple seconds. His was a neo seems like its a common issue, of course can keep it off the limiter but it happens sometimes

I'll change that to none of that is required if you stay off the limiter.

Raise rpm limit to 10k. Lol. Honestly man there's heaps of unopened rb25's out there pushing above 300rwkw doing hard track work and surviving for years. If you want to pull an engine apart to fit a crank collar and oil pump, go right ahead, you may as well put some forged pistons and rods in it and then you can go out and test how much limiter it will take before it goes bang. Then you can tell us how many seconds it took so everyone knows the limit :)

Not sure if the RB25 shares parts with the 26, but my car showed up with 5 destroyed main bearings from what was no doubt oil starvation. BUT the thing I want to add here is that mine also had 2 cracked valve guides. They are brittle and crack. I would change them for bronze and get the head overhauled in a heartbeat if you are pulling the head off.

If speaking of reliability.

No need to open the engine for 250kw. Use a quality synthetic oil and a quality tuner.

If you want to bash the limiter go right ahead and wait till it blows. Then pull engine and spend the $10K - $20K to make it stronger.

Bragging rights. 

370kW here, has about 27psi into it and used for track. Usually run about 23 to 25psi on the track. Motor has 350000km+ still going strong. Just pushes a bit of coolant after 10 hard laps at 27psi. Seems ok about 23 to 25psi, all it has are ARP non 2000 studs.

250kW is a walk in the park.

Well that kinda sucks. Tracking being a drift event or circuit?

      What brakes on R34 GTT(Europe)

      By Dose Pipe Sutututu · Posted

      Pads for R32 GTS-t, R32 GT-R non V-Spec (Sumitomo), R33 GTS-t and R34 GT-t are all interchangeable. R34 GT uses a 2x piston caliper, hence it didn't fit.

      Checked with amayama and nope, the full S2 manual set is not available anymore. Unsurprising, but still disappointing as the ? on availability gave a glimmer of hope.

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

      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.
