the k24 block has a 87mm bore...

well so does s2000, and also h22a.

so since the head designs are almost all the same, wouldn't that mean that we could introduce a type-s piston (11.0cr) piston instead of the 10.5cr that the TSX gets???

i'm curious to hear imput because these pistons can easily aquired..

something to think about..

what happens if you put an FRM designed piston in a "STEEL" sleeve ??? nothing or would something happen...

because getting a CRV block and dropping some Prelude type-S pistons would be a cheap 11.0cr block upgrade... don't ya think ?

please keep the thread clean

 

Do a search I think this question has come up be4. Wasn't too long ago I think.

 

under what ?

 

You need to compare the following info to determine if this is even possible

Pin size
Compression height
Dome displacement

 

Don't forget pin size also.

If you were to build a bottom end, why use a stock piston? It seems like spending the extra money for some aftermarket pistons that are stronger and lighter would be worth the extra 150-200 dollars.

 

The type s has an 86mm bore, not 87mm.

 

Prelude type s pistons are 87mm

 

k24 block has a bore of 87mm, when i was talking about the type-S i ment the prelude type-s pistons which are 87mm in bore.. H22a block = 87mm bore same as k24 and also same as s2000.
