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.

not sure if you can see it but here is the best pics i could get. it looks like a mix of dirt and metal filings.

[GTScotT]

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.

[lilcrash]

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?

ok undone all the head studs and given up for the night, i must have missed a bolt but i cant find it, im too tired

[DVS JEZ]

There is 10mm bolts atthe corners

[wolverine]

Don't do anything stupid like try to lever the head off until you know where all the bolts are hidden.

[lilcrash]

if i cant move it by hand i wont try to lift it. il keep looking around

[zebra]

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

[lilcrash]

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.????

[lilcrash]

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

[GTScotT]

lol RB50?

Maybe thats why its so epic

EDIT: on a serious note, did you do a leakdown test before you removed the head?

[lilcrash]

What is a leakdown test? All I did was a hot comp test and then put oil in cyl 1 and tested it again.

[mico]

too late 4 a leakdown mate lol.do that when the new engine is in.

[lilcrash]

Lol

[lilcrash]

Ok so opinions, block out or just sump off?

[zebra]

engine has to come out to get the sump off

[lilcrash]

Ok strange question, how do you all get around the legal stuff when putting an rb30 in? As far as I'm aware rb30s were not used in the 90s let alone in 2000.

[75coupe]

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...

[lilcrash]

Thanks, doesn't look like a good idea to me now. So rebuild here we go.
