I blew the head up in my built rb25det (snapped cam shaft), now when I pulled the head off I noticed that piston to bore clearances were quite large, about ~10 thou or greater I would say, there is nothing wrong with this, the rings seal fine, the bores are perfect and it uses zero oil but it means louder than normal piston slap, and it still rattles when warm, the bottom end however is in brilliant condition.If you aren't familiar with piston slap basically all forged builds do this, just mine happens to be louder than most. Now that I have the engine out he car I figured I could upgrade the engine at the same time I am looking to build either an rb30 or 26 so I am selling the bottom end off.

Now the block is about 8000kms old, had no issues when running apart from the loud piston slap, would be suitable for very high temp/boost applications due to the clearances, when it was running it was making 236rwkw on 18psi with a high flowed rb20 turbo and had zero issues. Here is the receipts for the work done, I personally did not perform this work but the previous owner did.

Has arias forged pistons, arp rod bolts, stock rods and crank, new bearings. Now the motor cost $5.5k to build but I just want it gone so I am very negotiable, so lets say I'll put the price as $1k for an easy sale, I am open to offers however . Here are the receipts for the work, if you want to confirm any of the details with the work shop then feel free to give Rob at Sabbadin a call.

If I get no interest in the motor I will pull the pistons out and sell them.

Still got it, had a few low ball offers for less than what a stock motor goes for!

C'mon people the pistons alone are almost worth what I am asking.

Just a thought mate. How are you measuring the piston to bore clearance with pistons still in block?. I had arias pistons in my Sr, and the crown of the piston ( above top ring) is actually a smaller diameter than the rest of the piston. Which when I checked when I pulled the head off, seemed like I has waaaay too much clearance. But once had pistons out clearance was ok. Good luck with the sale!

      Leak from Tokico BM50 Brake Master Cylinder

      By brillo · Posted

      Hi, SteveL Thank you very much for your reply, you seem to be the only person on the net who has come up with a definitive answer for which I am grateful. The "Leak" was more by way of wet bubbles when the pedal was depressed hard by a buddy while trying to gey a decent pedal when bleeding the system having fitted the rebuilt BM50 back in the car, which now makes perfect sense. A bit of a shame having just rebuilt my BM50, I did not touch the proportioning valve side of things, the BM50 was leaking from the primary piston seal and fluid was running down the the Brake booster hence the need to rebuild, I had never noticed any fluid leaking from that hole previously it only started when I refitted it to the car. The brake lines in the photo are "Kunifer" which is a Copper/Nickel alloy brake pipe, but are only the ones I use to bench bleed Master cylinders, they are perfectly legal to use on vehicles here in the UK, however the lines on the car are PVF coated steel. Thanks again for clearing this up for me, a purchase of a new BMC appears to be on the cards, I have been looking at various options in case my BM50 was not repairable and have looked at the HFM BM57 which I understand is manufactured in Australia.

      R33 GTST Steering Rack (49001-19U05) Rebuild?

      By Gantai · Posted

      Well the install is officially done. Filled with fluid and bled it today, but didn't get a chance to take it on a test drive. I'll throw some final pics of the lines and whatnot but you can definitely install a DMAX rack in an R33 with pretty minor mods. I think the only other thing I had to do that isn't documented here is grind a bit of the larger banjo fitting to get it to clear since the banjos are grouped much tighter on the DMAX rack. Also the dust boots from a R33 do not fit either fyi, so if you end up doing this install for whatever reason you'll need to grab those too. One caveat with buying the S15 dust boots however is that the clamps are too small to fit on the R33 inner tie rod since they're much thicker so keep the old clamps around. The boots also twist a bit when adjusting toe but it's not a big deal. No issues or leaks so far, steering feels good and it looks like there's a bit more lock now than I had before. Getting an alignment on Saturday so I'll see how it feels then but seems like it'll be good to go

      Leak from Tokico BM50 Brake Master Cylinder

      By SteveL · Posted

      I don't get in here much anymore but I can help you with this.   The hole is a vent (air relief) for the brake proportioning valve, which is built into the master cylinder.    The bad news is that if brake fluid is leaking from that hole then it's getting past the proportioning valve seals.   The really bad news is that no spare parts are available for the proportioning valve either from Nissan or after market.     It's a bit of a PITA getting the proportioning valve out of the master cylinder body anyway but, fortunately, leaks from that area are rare in my experience. BTW, if those are copper (as such) brake lines you should get rid of them.    Bundy (steel) tube is a far better choice (and legal  in Australia - if that's where you are).
