Okay I am reworking a Neo head and it so happens that the head I got is missing some parts. I initially thought I would just swap over my parts from my running head when needed but now I am thinking that I want to get the parts and keep my running head in tact. My question now is what parts from other RB25DET's can be swapped over. I am after, Neo cams, Neo Cam Gears, Four intake valves, four exhaust valves, four buckets/lifters with springs and retainers and also the four shims as well (four intake and four exhaust buckets and shims) and lastly all the cam caps with bolts and cam oiling lines. What size are the guides for both intake and exhaust on the Neo head as I want to replace all of these same time as I am working on the head? Let me know what can be used off other RB25DETs or do I have to get Neo specific parts? Yeah I know I should have gotten a complete head but they are quite rare over on this side.

You can use rb26 cams and camwheels if you are happy to lose the vct. valves and springs cam be bought aftermarket, buckets will be genuine only i would say, but vg30 ones may be the same. rb25 caps and bolts shoudl be the same although you will have to have them line hones as you are mixing and matching sets. hope this helps.

Well I really don't want to lose the VCT as this project is based on a Neo head with an RB26 Block. I have also adapted the RB26 ITBs and toying with the idea of doing a twin turbo setup. If anyone has a scrapped Neo head it will be very helpful. I will pay to have the stock items shipped to me over here in Trinidad in the West Indies. This project is not urgent as I have other pending projects so whenever I get them I get them but I would like to have them in hand for the future build.

    • They usually get made by hand as part of any such swap.
    • Was planning on getting an R35 MAF and the adapter, should this be okay? Also any idea where I could get my hands on an intake pipe?
    • I mean yes, if you're starting from scratch on an unknown engine yes you don't need to be doing all kinds of math in the background but if you're doing relatively minor changes like AFM + injectors + boost up with some aftermarket turbos it takes quite a bit of math if you want to do something like maintain OEM fuel + timing tables but compressed and then a bit more load scale up top. I think I've spent too much time working on big engineering nightmares though so I'm a big fan of trying to constrain the scope of whatever work I'm doing as much as possible and trying to get it right before moving on. For example, a local owner just did the usual E85 + single turbo conversion to his R32 GTR and nearly burned his car to the ground doing some spirited driving up the local mountains. Turbine is unshielded and too close to the hood insulation. It's tough to balance "just get the project done" and "seemingly small details can cause massive setbacks I'm not willing to deal with".
    • No idea about Neil's steering wheel, but I have the same behaviour in the Stagea. I doubt it has ever been messed with so might be normal. Indicating to turn right at a roundabout and correcting even a little bit to the left to go around will cancel the indicator. Never considered it an issue other than it being a bit odd.
    • Does anyone know if this is off centered? Looks like it, when I indicate to go right, but turn my steering wheel slightly left it cancels (was always like that even before I started messing around with it) was wondering if anyone else has the same issue?
