First of all thanks for your help drift.
If I do go with forced induction later on, and I do use ductile iron sleeves, how will forged pistons hurt the (FRM sleeves) engine in the long run.
If I do have sidewall contact and damage, can I be sure that a 0.25 overbore piston will suffice? will such an overbore make a less reliable engine since it's weaker? Is my understanding correct? Can you elaboratemore on the slipskirt design?
Sorry I did'nt mention earlier but my car is a '97 non-SH(so h22a1).
Also are AEBS T-sleeves much more durable that ductile iron sleeves?
I had assumed that forged pistons and forged rods mated to the stock crank would be a relatively solid bottom end setup.
i've done alot of research into the products but I have more questions knowing which ones are good and maybe proven.
Any input will be appreciated.
first off, like stinger said, your motor is an H22A4, not A1.
you'll need to inspect the cylinder walls to see if it's worth rehoning or not. if there's gouging, you wont be able to rehone and use rebuild pistons.
you need to decide if you're going forced induction or not. it's not worth me explaining all the stuff about strengthening if you're not planning to boost. besides, you can do a forum search for that info.
as for the slipskirt pistons, they're basically the S2000's piston design. they're forged, but designed to minimize piston skirt to cylinder wall contact and damage while used with FRM liners. standard forged pistons will destroy frm liners due to piston to wall contact, as forged alloy is harder than frm. the slipskirt design is the only way to run forged in an frm liner without damaging the liner.
i have no experience with AEBS products. all i know is their drag car is a Ford Focus, so i question their extent of knowledge on Honda applications. Darton sleeves are a brand i have heard nothing but good things about.
a small overbore for the sake of rebuild at .25mm over will not reduce the structural integrity of the motor. this is Honda certified rebuild specification.
