Forged pistons for f22a/b

[bournetc]

I'm having a really hard time finding forged pistons for my car. I've found connecting rods easily enough but pistons seem to be only here: https://www.raceeng.com/p-31047-wise...t-526p85r.aspx so I was wondering if there were any other options and does a set mean 2 or 4?

A quick google search brought up Arias and the Race Engineering link you posted above. Less than 2 minutes of work. I'm not sure why your having problems finding more places to buy pistons.

because the ones you linked are 86mm and the engines (f22aX and f22b2) are 85mm? I mean sure I could get it bored out an extra mm but that's gonna be another $200 or so on top of the price of the pistons.

I wouldn't expect an engine with 200,000+ miles on it to pass tolerance specs needed when installing forged pistons. There's a possibility it's not completely round. In addition, you're going to want slightly more loose tolerances if you're running forged pistons that have different expansion properties and you plan to get on it regularly. If the intended application is forced induction, the heat you'll be exposing the piston to is even that much greater.

My intention was to get it honed just not bored, the car only has 90,000 on it so I figured it wouldn't be too much out of tolerance.

To be absolutely certain, you're going to need to tear down your block, send it to a machine shop, and have them hone and measure it. Paying the extra for a 1mm overbore and getting the 86mm pistons to be 100% certain that everything fits properly might be your best bet. Sucks to have to spend extra money, but it would suck even more if you build the engine and blow it up in a short time because you cut corners.

Most shops will do 10 or 15 dollars a cylinder

If you are putting new pistons in it is **HIGHLY** recommended that you bore your sleeves anyway. Pistons slightly distort themselves and the cylinders slightly after enough miles. Your going to put perfectly round pistons into non-round holes. Not a good idea especially since you want to boost it.

The cheapest I've seen is $30.

I think it depends on where you live. If you live in an area where shops are plentiful and the business is competitive, there will likely be places with low prices. If you live in the middle of nowhere, the one or two shops in town can set the price how they see fit.

I've even known shops to charge more for import engines, claiming "special tooling" or "tighter tolerances"... when they will freely admit to anyone they believe to be anti-import that the reason is simply because they "don't like that ricer shit".

You can find Arias pistons for about $160 less than that posted price.
