You got the Neo head, just source a series 2 Na RB30 block, there are plenty around. All your current ecu injectors and ever thing else still works as normal, need a return. The driving ability from the Rb30det to a RB25det is totally different, heaps more torque, plenty of power band and lot faster response.

Im not convinced thats metal man.

Whenever Ive had a metallic issue like that the alloy is generally coarser.

Have you checked everything? If that was from the turbo you would have crazy shaft play, easy thing to check and rule out THB. It may be dirt sucked in from when you had the rocker breathers open.

I don't think it's worth worrying about. It just looks dusty. I think the metal may have gone in during the removal. As they are fairly large bits. So far I've got the top half of the plrnnum off and the turbo off and timing cover off, how do I loosen the belt? Is it just springloaded?

you wont be able to move it side to side...will only lift straight up

as said before there are 3 M6 bolts (10mm heads) 2 at the rear on either side and one on the turbo side front

Massive PITA if you still have the manifolds fitted

there is 2 bolt holes at the rear of the head but there isn't any bolts in them, i un did the bolt from the power steering pump that was into the head but i cant find any more bolts, does anyone have a picture of the bottom of an rb25 neo head? also there is E T written on my intake cam with paint pen.????

ok head is off, apart from the sand in the bores that ended up in there when i lifted the head all looks fine so i guess i just have to keep stripping until i find something wrong.

i find it amusing the stuff nissan stamp into their parts, like my valves all say 5L

definitely a strange question considering all the info you need has been covered before...

Are Rb30's Legal In All States Of Oz?

a man who needs others to do shit for him is a man not able to do shit for himself...

    • Probably speedometer itself if the odometer is ticking. If the needle is stuck from a bit of grease or something that can cause it to stay at 0. Or a cracked solder joint in the speedometer can do it too.
    • Thanks Fella’s   to take this off topic and to elaborate a bit more. I have an rb25/30 going into a r32 GTST.. expected to make around 600-700hp. Would you?   A) R34 GTT box   B) CD00#?  I’ve seen a few posts about the CD swap and sounds fairly involved with making it fit etc but if it’s worth the work then I’ll go that way
    • Lower at the hubs. Funny I forgot to mention that part. Do this pull here I turned the camera off too soon but the graph shows a drop at the top and that was because the pipe from the turbo blew off. The tuner said we could’ve made possibly another 15 whp. He also added if I switched to ethanol we could up the boost some more as well. I was comfortable capping it at the most of 20 pounds. Turns out the turbo pipe just needed a new worm clamp. Got home replaced that then did a third gear pull from 3k to 7200 rpm and the power was great to the top. I just got an ecu mounting bracket from IEE that I need to try and get everything to fit well. It’s a PITA to get the harness and ecu fit properly behind that kick plate 
    • He means "as opposed to mechanical cable drive". Older cars (R32 for ex.) had cable drive. Later cars with essentially the same gearbox, ie R34 GT (NA RB25) used essentially the same box as the R32 GTSt, but instead of a cable drive, had an electronic speed sender plugged into the same hole in the box, running from the same little gear that would have run the cable. Some of the shittier later cars use a speed sender on the nose of the diff, or the ABS sensors.
    • Lower than engine, or lower than it should at the hubs? Either way, that is a nice power figure and I'm not surprised you say it rips now. What stopped you from turning it up any more? Injectors? Or did it just stop responding to boost?
