Sounds like they will fit my RB25 NEO! Would I be right?

I dont think they fit NEO engines.Tomei have a different part number on their website.But the best way to find out would be to take your car to your tuner and get them to tell you what part number and cams would suit your car. :D

Does anyone know what effect the CAMS have on fuel economy?

Speaking generally..

Mild Road Cam 257deg-260deg. Gives low end improvements and used in unmodified engines suitable for all car types and gives a smooth tickover. Fuel economy may actually improve and power and responsiveness will be greater.

Fast Road cam 270deg-285deg. Good compromise for a road car the tick over is still fairly smooth and emissions are within legal limits. A good choice for a car used daily and for weekend track use and perfect for a hot hatch. This profile still gives reasonable fuel economy and a choppy tickover.

Competition cams 290deg-320deg. The best performance profile for an engine which works continually over 3000 revs. The tickover is very lumpy and irregular and the car is lumpy to drive round town. Fuel economy is pathetic and it is unlikely that a car with this fitted will pass any kind of emissions test.

      RB25DET with solid lifters - which cams ?

      They are under bucket shims. Tomei provides a test shim kit and then any measurement of shim required.

      I always wondered how you were supposed to buy a set of 24 buckets and somehow magically have every single one of them yield exactly the desired clearance. I would have thought you'd need to assemble a cam with either 12 "sample" or "example" buckets of known top thickness (or a single such sample/example 12 times over!!) measure clearances at every valve, and then do the usual math to work out what the actual "shimness" of each bucket needed to be, before buying the required buckets to make up he thicknesses that you didn't have on hand.

      I now seem to be limited in power due to my rev limit/hydraulic lifters in my built RB25. I'm looking into converting over to Tomei solid lifters. Question for anyone that has done the conversion. I was always under the impression that when using the Tomei solid lifter conversion, you would also require new valves (Longer or shorter stems, I can't remember which).  I don't know where I got this idea, as so far I see no mention of this in any of the Tomei documentation. It just states I need the Tomei solid buckets, solid lifter cams and upgraded springs. As my head is already built, all I would need is another set of 1000$ Kelford cams, 500$ buckets and about 4H hours of my time installing and I'm off to the races!?!? There's no way it's that simple, I must be missing something?

      Why am I hitting a power wall with my stroked RB25?

      I couldn't agree more. I should have started from the get-go with a NEO or solid bucket conversion. I started looking into converting over to solid lifters yesterday. Now for some reason I was always under the impression that when using the Tomei solid lifter conversion, you would also require new valves (Longer or shorter stems, I can't remember which).  But I see no mention of this on any of the Tomei documentation. It just states that I need the Tomei solid buckets, solid lifter cams and upgraded springs. As my head is already built, all I would need is another set of 1000$ Kelford cams, 500$ buckets and about 4H hours of my time installing and I'm off to the races!?!?
