    hey whats up. I was just wondering if its worth building an LS all motor? I know this probably contradicts everything about building a honda and not using vtec, but the issue i wanted to focus more on is about the valve train. I came down to two different setups (head choice): keep my LS head and use aggressive cams? Would crowers 62404 be a good choice, plus crower valve train? (Who else builds nonvtec valvetrain?) Or just better get a full civic type r head and go vtec?

    Just to note: My bottom end is an LS with CTR pistons, and pending on aftermarket connecting rods. I know that if i use a vtec head, my compression ratio will also become higher; i guess thats something to incoperate when deciding my head.

    thanks in advance hondaswap :worthy:

    forget the CTR head business.. way to expensive for what it is...

    get a b16 head and port it... if you are planning on building the valvetrain up , then you would want something more aggressive than CTR cams anyway.

    well i planned to get a b16 head with b16b valve train and cams...what i wanted to know was will i make more power with a stock b16 head or a b16 head with CTR valve train (including cams) or an LS head with crower valve train w/ 62404 cams). thats basically what it comes down to for me. thanks in advance.

    So crowers 62403 are more aggressive then having type r cams? and can someone help me with this issue on the CTR pistons? can i still use them on LS rods? i thought i read on a thread here that they fit...

    nope- ctr pistons wont fit ls rods. end of story. if you read that they did, the poster is a moron.

    in an LS, you can't have type R cams. the ls has 4 less lobes than a vtec cam does.

    note:(civic type r cams are larger than itr's, but i couldn't find the itr specs off hand.)

    Description--------Duration @ .050" ----------- Lift

    Civic Type R--------I-233/E-224----------------- I- .449 /E- .417
    403's --------------I-211/E-210------------------ I- .423 /E- .409
    GSR ----------------I-230/E-216------------------ I- .423 /E- .378

    they have less duration, cuz they don't rev as high, but offer some good lift.

    yes i know that the LS head has 4 less lobs...thats why im asking if i would gain more power by doing a vtec conversion, or leaving the head and using 404 nonvtec cams.

    oh yah about were i read about the ctr pistons with ls rods...no offence but i think it was by you

    http://www.hondaswap.com/forums/index.php?showtopic=11

    i dont know how to use the quote but u wrote this

    "BLOCK SET-UP

    LSVTEC block MILD: (250)
    CTR/TYPE-R pistons (330)
    LS rods "

    ARP Head Studs (Thanks Bill)

    My engine isnt built yet waiting on people to come through but it will be! All motor all the way. I will eventually go LS-T though but not for awhile.

    slap in some 62403 cams with springs and that was basicly my setup . . . i think you'll be very happy with the out come.

    good luck, happy building

    and do yourself a favor and get a set of new usdm b16 piston rings . . . it would ahve saved me 8hrs of my time rebuilding the motor in the car in a saturday afternoon :doh:
