RB25DET head for sale

Note: This head has been modified to suit a RB30 Bottom end, whilst Retaining VCT (PROPERLY!)

Head work Completed:

- Full clean up

- New welsh & oil plugs,

- Decked

- Crack Tested

- Straightness Tested

- Full Valve Cut

- New Set of Valve Stem Seals

- Certain Plugs welded as per high HP requirements

- Weld and Fit new VCT Boss

- Weld and Shut front Oil Feed to head

(this head owes me $1800)

Story: First motor I ran in failed, this Head was on it. The Head had some alloy in it from the oil pump. The head has been cleaned out, and came up good, but I would recommend probably be cleaned again for good measure and plugs replaced.

I would also recommend new lifters as the lifters that were in it obviously will have some ally inside, so would recommend new lifters. (I have cleaned them and they seem ok and have put th em in their original positions, however, I wouldn't take the chance if it was me)

can sell with original cams (that were not in the motor when it failed and they are in VGC, these are the original cams from this Head, the cams that were on the head were tomei ones.

The cam bearings and cap shells got scuffed a bit, but Linished up well and are within spec. (feel free to re-measure)

I wanted to keep the head as a spare, and if no one buys I definitely will, else...

Asking $650 ono.

Item is in Brisbane, Pickup only. Call number provided, if you havnt received a pm.

      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!?!?
