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.

    • Yeh I think i'll message an old contact i had for ages that manages his own tyre shop now.. n tell him what i want n work with him before ordering..  Got this 17x9 +30 Driftteks on 245/45/17 PSR Drag Radials on the rear.. They fit well - for your reference in future - Rear guards  have been lipped in & minimal to non flaring of the rear Gaurds.  
    • If only it were that easy! I also needed to remove seats, shocks, brake calipers, send my car through a fence, and use measuring and ended up guessing because I didn't remove seats, shocks and brake calipers. It can be hard sometimes Can be a little more complex than 'just measure' if you want to truly measure the entire wheel through all of it's suspension travel. But if you aren't going for every last mm then yeah, you can check the space you currently have and guesstimate.
    • If you own a car, and it has wheels on it, and you know the offset of those wheels, and you have a measuring device, you have everything you need to work out if other wheels will fit.
    • Will this fit? but they are staggered set - RAYS 57DR SEMI GLOSS BLACK 18x8.5 +37 | 18x9.5 +38 5-114.3 STAGGERED SET   or If no go could just get a set 4's wheels of 18x8.5 +37 5-114.3 - would i run 8.5's 235s up front n 245's at the back if I do?   Thanks.        
    • Put a clamp on your return line. I have a feeling it's sucking air, and introducing bubbles to your fuel. With a lot of fuel, less problematic. I'd honestly be redoing all the lines in the tank and clamps on everything.   Also, you've given two different answers to the same question: Asked if being followed by the police you could get down to use the whole tank, you said yes you could, so long as you keep off boost. However, you then followed this up that free revving, it would also cause the issues. I'm doubting free revving is enough to make any noticeable boost on what is likely a decent sized turbo.   So now I have to ask, can you actually drive it lightly and use all the fuel, or does it break up even free revving? Also, have you put a fuel pressure gauge on it? Can you hear the pump change noise at all when you're having this issue?
