Well, thanks for the info, but we already knew you could run forged pistons in nikasil sleeves. I've seen it done as well and it's even advertised by a few places on the web. The discussion here is that our sleeves are not nikasil or straight cast sleeves. They are Fiber Reinforced Metalic like on the NSX and the S2000. The FRM is a liner which is placed in the sleeve while casting.
Expansion of a forged piston is dependent on it's silicon content. High silicon forged pistons like SRP's do not require the warm up time that low silicon pistons like JE's do.
Anyone else see that S2000 runs forged pistons with FRM sleeves? I wonder if they do anything to them or if it's just the ring package you have to change to run the pistons on FRM sleeves like some people say. I guess when they start running standard forged pistons we'll have our answers.

Here's a reprint from Automotive engineering that specificly mentions the H22a has FRM sleeves.

Hmm... Here's another page on FRM liners specificly talking about the NSX.

I assume that was taken from some marketing paper since there's a bunch of pages with exactly the same wording. (unless it was stolen)
