i am building a lsvtec . i dont want crazy power just more than i have and some torque oh much needed torque i have a 98 civic ex. what i am useing is a b18b block to start with with all stock internals should i swap these out for aftermarket or use internals from another b series engin or just leave the stock internals ? all i want is 150-200 hp max , if i use pistons and rods from another bseries engin do i have to bore or are the bore and stroke the same the same if i should use aftermarket what should i use or is i use from another b sweries what should i use. then comes the head i have the b18b head but i want v tec so should i go with a b16 or a b18. i have done a bit of research and i am not sure about the machining on the head or the block or can i skip this if i buy a ls vtec kit such as (golden eagle) and last i need a tranny i have a ls tranny but frome what i understand they are junk and i need a hydro tranny what tranny would be best for this setup. thanks for who ever helps me out

 

jdm b16 pistons machine to fit on ls rods
bore and hone to size of piston...
ge ls/vtec kit
b16 hydro tranny
headstuds & rod bolts
and upgraded cams in a b16 head should get you a nice beefy powerband and a decent n/a car...

btw search

 

i to am building an ls vtech i have the block all done up its b181a or b but i have brand new rods pistons and a crank from a gsr. i also have a ported and polished type r head with upgrades springs and valves and skunk 2 cams and gears i have the skunk 2 intake manifold and a chiped computer from a 96 gsr 5 speed wut else do i need for the vtech ls swap alsowhere can i get this stuff for a good price. i am farly new to this import tuning.

 

to correct you...when using a gsr crank and rods...you are not building an ls/vtec...your are building a gsr in a ls casting....the reason why people use ls's is because it has a longer stroke from the crank...now by swtichin this for a gsr crank etc...you complete eliminating the longer stroke....you might as well have just bought a gsr shortblock and had some nice oil squirters and girdle...and you have an obd2 chipped ecu...i kinda find that hard to believe....get an obd1 and run uber or crome for engine management....

the classifieds are you friend...do research on sellers to make sure they arent scammers or visit the retailers on HT...they are all great and willin to help you get rolling

 

thank for the help . so i need b16 pistons stock ls rods. do i have to bore the block for the b16"s to fit or i will be fine they just slip right in .

 

boring is not necessary, unless you have any scarring or nicks on the cylinder walls. a machine shop can determine this if you are unsure.

if you decide on stronger rods, check my sig...

 

resized rods ,,, not sure what that means

 

resizing the rods is needed when upgrading rod bolts.
the higher torque setting of aftermarket rod bolts will make the rod end ''egg'' shape

 

the rod ends of the ls where the meet the pistons...are larger than what the b16 piston can accomedate....1mm needs to be shaved off on each side of the rod...any machine shop should easily be able to do this....i also recomend shot peening the rods...
