i know.. this might be the dumbest question ever.. but.. i have heard it is possible to swap pistons from the underside of the car. is that true? If so.. do u get it up on a lift.. undo the belts.. the oil pan.. oil pick up and unbolt the crank? i have a N/A sleeved and high compression engine installed in my prelude but someone who is interested in purchasing it would want to go boost. i know u cant go boost running 11.5:1 comp so the pistons would have to be changed. do u have to un-install the engine and take the head off to do the swap? i know its probably a dumb question but i heard it somewhere... just looking for the truth.

thanks guys for the help.

 

why would u have to unbolt the crank

its possible yes, but plastigauging under there is a pain in the ***..

yes its possible but u cant pull the crank with out dropping the tranny, you pull the head, oil pan, windage tray, rod caps n push the pistons out the top, use a ball honer to re hone then re gap new rings n put em back in. takes about a day.

 

ahh no $hit. so remove the pistons but leave the crank still attached by going through the head.. how much do u think it would cost to have this done by a professional? and i dont consider myself a professional. lol

that sounds like a good time to change over some cams and springs... i mean.. might as well.

no clue its gonna be hard to have someone do that cause no one wants too...its not hard...id do it my self if i were u

 

yeah, i did rods and pistons while the motor was in the car, on the lift at my shop. it was quite easy, and didnt require the process of pulling a motor out. as long as you have the right equipment its no problem at all.

 

you guys aren't worried about replacing the main bearings?

 

the main journal bearings were replaced when the engine went through the entire rebuild for n/a. that was done all of like 2 weeks ago.. or so.
