Hey all,

I'm about to pull the head off my RB25 Neo in an attempt to fix a sticking valve problem, and I'm thinking I should just get it reconditioned and while I'm at it upgrade the valve springs and retainers, possibly the valve guides as well.

Is there anywhere in Perth that has experience with RB's or that people would recommend for me to take it to to have all the above done? Removal and refitting of the head I can do myself. I've had a look in the consolidated workshop thread and seen Bert Vosbergen listed in there, anyone dealt with them before? What are they like price-wise? Any other recommendations?

Cheers,

Martin.

Hey Martin did you give Gerry a call? If he isn't on the road when you call then he will have a good chat and can give prices. They make their own guides suited for high lift cams incase you go down that path later on. Not sure how many Neo's they have done but well worth the chat. Just make sure you have at least 15-20 minutes to talk:)

Another option is Sam @ N&A Cylinder heads in bassenden.

thought about droping cams in at the same time?

Thanks mate, I'll check them out too.

As for cams, yes I've thought about it. Still thinking about it, I am very very tempted. It's going to depend on how much the labour will cost me though I think, if it's not too expensive then I'll get some Tomei Type-B's as well.

Make sure the valve guide clearance is set correctly. Have seen alot of head shops get this wrong and have the same problems you're experiencing.

What would cause them to be incorrect? My head has never been off before. I'm fairly certain the current problem is being caused by a bit of debris getting stuck in a valve, as when I installed my Plazmaman plenum I made a mistake which caused the manifold to twist and break on the cylinder 1 collector.

Haven't given him a call yet, I'm actually a bit sick at the moment and I hate talking on the phone when I have a blocked nose lol. I will definitely give him a call though, I'm quite keen to see what he thinks :)

Thanks for the feedback mate, I still haven't got on the phone yet as I need to wait for the space before I can pull the head off. Mind if I ask what you had done there?

All the porting i did myself. Was a crack test, relieve head to suit big cams, his valve guides, race valve job think it was 3 or 5 angle, shimmed up/adjusted valve clearances and a reface.

    • It is a kunfine Android screen . Does anyone know the wirering diagram of the fuga ??
    • just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.   
    • My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.
    • Awesome, thanks for sharing!
    • To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?
