OK, I had the idler bolt snap on my Rb25det Neo, which threw the cam belt on the free way at 110kph. As a result, both sets on valves are bent. yes all 24.

So engine is in bits, and valves are out, but here it is...... Where can I find replacement valves other than Nissan. The place where the head is cant source them, and well the ***** on ebay say they can get them, but that was over 2 weeks ago. They arn't the same as a normal rb25det, as mine is a NEO, they seem to be a different size to others.

Is this normal?

Inlet About 104mm head 30.4mm tip 6mm shaft dia 6mm all approx. as I don't have verner

exhaust about 98mm head 29mm tip 4mm shaft dia 6mm

Nissan want, inlet $35 ea exhaust $59 ea

With all the rb's out there, there must be someone who does them cheaper the nissan

Need help pls

Erics performance parts in the US sold me valve guides at a good price. They have a fair bit of stuff. Cant say I ever looked at valves but worth a try

As suggested though, getting a second hand head and robbing them out of there would be cheapest

I bought some pistons from Eric's Perf ebay and took forever to arrive. I was a good price but after the sale communication was lacking.

He did come through, but was frustrating for a bit for my one experience.

Yer I been looking for a 2nd head, but no one has 1, or wants to part with it cheap or wants the same price as the valves....

The normal rb25 heads are different to the NEO. The only thing that might fit on the both of them is the exhaust manifold. Rest of hardware would have to be changed.

I bought the ones from ebay over 2 weeks ago, and they are having "problems from there supplier" getting them. Now Im in a dispute trying to get my money back and got to look else ware. i got to wait for money to get back before I can buy new ones atm.

Is there a link to Amayama Wolverine so I can check that out?

I agree. Im m very tempted to get one to port. If it was sa I would have bought it.

Of course they are going to cost what the valves alone cost, it's a whole head!

      G.G.C. (Gibier German Cook) restaurant in Motomachi in Kobe: A tiny 2 floor restaurant that was founded in 1976. The original couple who owned/ran it retired and sold the business to a corporation who pretty much tried to keep it the same as it was.  Lots of lesser known (to me anyway) German beers available.  Venison with vegetables. The meat came from deer from Hokkaido. The chef told us that there's a whole industry around the use of all parts of the deer from the antlers to the hooves. Sure enough, directly accross the street from this restaurant is a shop that sells all manner of utensils, clothes and objet d'art all made from deer skin, bones and horns.... also owned by the same corporation. The venison was super tender 😋 Various decorations, a lot of which were quite old, no doubt from the original owners. A nice pilsner too which I'd never seen before.  It's well worth a visit but check the opening hours, they're closed on Wednesdays, only open 11:30am - 3pm on Mondays and Tuedays, 11:30am-3pm for lunch and 5pm-11:30pm on Thursdays, Fridays and Saturdays, and 11:30am-3pm and 5pm-9pm on Sundays. Last order is 30mins before close.

      Another BK R32 GTR money pit...

      Have I not posted since 2022 ? wow... Yes, it's pretty much finished mechanically. I'll probably sell it soon as the old man is 80 in November, so 99% he won't ever drive it again. I don't really need 3 GT-R's and I haven't driven any of them since September last year - correction, drove my 33 earlier this year on Australia day. All of them have been like this since then.

      So, after talking to Tyson at Auto Tech Engineering about my "cunning plan", he suggested to "not piss money away on stuff that the car probably doesn't need" (the max IAT at the end of the 1/4 ever only seen around 30°C, which is in no way a issue, and as such, for what I use the car for I really don't need colder IAT anyway The whole point of the "upgrades" that I thought about doing was that my IAT started creeping up from 25°C to 30°C when cruising, then drop back down, then raise back up, rinsing and repeating, it has never done that before, so after talking to FI interchillers they assumed that it was the Bosch pump starting to fail, and if I was going to replace the pump....... I would do my usual thing of "while where in there" But, Tyson said he has seen similar things happen to IAT with failing or leaking AC compressors on other cars with interchillers, and as the AC compressor is 22 years old it is probably well on the way out anyway, and if a electric water pump fails it stays failed and doesn't just speed up and slow dow, but if a AC compressor starts to fail or is leaking, it will fluctuate and give a typical result to the IAT He said he could test the compressor and see how it is functioning and pressure test the whole system, but, as I do, I've just got them to order a new compressor to install to start with, and do a AC service and see if that fixes the issue That way, if it is the compressor, I wouldn't be spending lots of coin on something that wasn't the issue, and not actually needed, as the stage 2 kit, and pump, comes in at around $2k in parts alone, not including the plumbing and other parts that will be required or labour  And apparently the Bosch pump I have is really reliable and well up to task for the flow/pressure requirements that I need to keep my intercooler and massive amounts of boost heat (7 psi LOL) under control giving a nice and cold IAT A big shout out to Tyson for this, not many people will talk a idiot out of wasting money on car modifications, and the saved car budget funding can be wasted elsewhere on things that I may, or may not, need, like a nice new leather SS interior with red stitching......maybe I can convince the Minister for War and Finances into a nice trip down to Victoria for a week away to see the sights (I'll explain that I will need a hire car once we're down there so we don't have to worry about the Commodore being parked up on the streets at night, and it just so happens there's a joint that I can store it during that time) $1680 for all of the interior trims, + installation cost (I'll ask for a quote to install the trim if the new compressor fixes the issue)   https://leatherseats.com.au/products/leather-seats-trim-skins-kit-to-fit-vt-vx-vy-ser1-ss-green-black-diy-install
