I just picked up a Spirit RT that is supposed to have a 2.5 TIII setup. Would like to know what is needed for that so I can verify it. I guess I can measure the stroke w/ a rod through the plug hole. From what I read, stock 8v 2.5 pistons would fit but cause a lower compression ratio. The proper way is to use the custom ones FWD-P sells?

I'm hoping it has all this and was done right
