okay i bought a b20vtec engine both head (b16a) and block (b20b) in stock condition, now i know that this is not very reliable but i have this idea in mind------> i dont want to sleeve the engine because i dont have enough money for that, so i was thinking of putting in some decent compression pistons (JE 10.5:1) along with new connecting rods eg. crower, eagle ect. with ARP rod bolts, and ARP head studs. My goal is to get at least 180 hp out of this engine. It will be my daily driver so i need reliability, i would like it to be able to rev to at least 7500- 8000 rpm pretty safely if possible.

let me know what you guys think about this.

 

put in new bearings and have the bottom end balanced on top of what you listed. and depending on the condition of the sleeves, you may have to do a slight overbore.

 

okay this may be a stupid question but........ if i buy after market pistons and rods that already weighed eg.. (all 4 brand new rods weigh 250grams)
or (all 4 four pistons weigh 450grams) do i really need the balance the rotating assembly if the rods weigh the same and the pistons weigh the same? sry if this is hard to understand. or u can just tell me what is involved in balancing the rotating assembly. thanks man

 

if the rods and pistons come balanced from the manufacturer, it's still a good idea to get the crank balanced. plus it's not too expensive.

 

so if i do this setup will the sleeves be okay? on my block the sleeves look in very good condition. but i also know that b20 sleeves are quite thin and have a problem with cracking do to the r/s ratio. so i take it that balancing the bottem end will help decrease load on the side of the cylinders and the main bearings??
