building my first motor, got a little money, and a little knowledge, but i was thinking the other day about something.

what i need to know is, what is the bore and stroke on an LS motor, and a B20, cuz what i was thinkin, if the LS bore is the same or greater, but the stroke is less, then i could swap out a b20 crank, and make a budget stroker out of it(with pistons and rods of course) kinda want to get started on this thing, and dont want to have to tare into the bottom end after i start on it and THEN find out this would help. thanks yall.

 

bumpety bizump uh lump

 

OK!
B20 and B18b use the same crank and rods
same stroke 89mm.
the only difference is that the b20 sleeves are 84mm and the B18b are 81mm.
everything else is the same.
that the only reason why the b20 is a 2.0L motor.

 

what is your goal.
all motor with high compression or you are going turbo.

 

n/a. i was thinkin that the bore might be the same but the stroke would be greater, but yeah, i was wrong, gotta learn huh? why what was you gonna suggest? either way, thanks

 

because the b20 sleeve wont last for too long. but with good tuning they will.
Are you runing a Vtec head with this set up

 

yeah, ls vtec, should i sleeve the block? with bigger pistons or just bore it? im lookin for hi-compression pistons and good rods, but i dont think i need some 700+hp crower rods. getting a lot of different opinions on what i should buy, and with no experience in this matter, i dont know who is bs'n me and who is real. if everything goes right, head will be reworked by R N D in charleston SC, pnp, 3 or 5 angle valves 1mm over, dont know what kinda cams would be best, any suggestions? would like to get 240+ hp. dont know if that is even pheasable. i know what CAN be done, just not what SHOULD be done.

 

is up to you.
if you have the money i would sleeve the ls block to 85mm.
if not just bore the ls to 82 or 81.50mm

 

what kind of hp is doable on a decent build, with out nitrous on N/A? if i could get 300, then i would like to build to that, but i dont see that being anywhere near possible with out boost. what can i expect to get out of a built N/A LS/VTEC?
