change pistons

[deevergote]

kinda like when u change the clutch. the old grooves dont line up with the the new.

Exactly. Any surface where metal parts must properly seat must be prepped before a new part is introduced. Pistons, valves, brake pads, clutch... (yes, the pads and clutch aren't always a metallic material... but the concept of proper preparation is similar)

if the block is low mileage, you can get away with honing it at a 85mm piston because a forged piston requires a lot more clearance.

bring the rods to a machine shop and have them hone the small end to accept a floating wrist pin setup and get the big end re-machined to ensure you dont spin a rod bearings. it's fairly common on honda engines.

will the machine shop know what i'm talking about if i say that. cuz i'm not sure i could explain something like that to them, as i dont fully understand everything yet

Find a machine shop that's familiar with Honda engines, first. Then ask them. If they don't follow you... either learn more yourself, or find a shop that DOES know what you're talking about!

Wes, couldn't you do that if people sent you the stuff? (not that I'm promoting doing business here... but it's my rule... )

would i need to do that to bisimoto rods? or just other rods?

thats very common for shops to kinda specialize even though they dont say it like that. which is kind of wierd though because my shop does it all. we build euro, import, domestic, marine, diesel...blah blah blah.

but yea, contact bisimoto first and if he doesnt want to do it for 80 bucks then you'll know

[theSOB]

so u think it'll still have to be done to his rods for extra $$?

[wed3k]

you can use his rods or if you get a set of oem rods, those can be modified but if you get those reconditioned, it'll cost almost as much as a set of chinese rods.

IMO, if you're going to spend the time and money to replace everything inside the block, and you're seeking additional performance... spend the money on quality parts, and do it right.

is it hard to change pistons in an f22a1.some one told me u can remove the oil pan and disconnect the rods to pull the out the pistons. is this true or do i have to rip the block apart.

Correct me if I am wrong but in my limited experience you have to take the head off to get the pistons out. I think the pistons catch on the bottom of the block if you try to just drop the oil pan/crank and slide them out.
