    I was planning a gsr swap and eventually jrsc in my 89 crx hf but I've recently found out that I'm going to have a baby so it kinda changes things. I was going to sell it it and get a four door but then I thought screw it. I'll buy a daily driver and keep the crx. My crx already has a b18a1 swapped into it and I was considering building using
    http://hondaswap.com/threads/building-an-ls-all-motor-monster.31401/

    Or ls/vtec.
    Ive heard ls/vtecs are monsters but so far all the research I've found on ls/vtec are guys running 14-15s quarter miles and dyno at 150-160whp.
    I did the math
    Ls vtec= $3000 give or take
    Built b18a1= $2000 give or take

    Built b18a1=150+whp(link says)
    Ls vtec= 150+whp(research says)

    I was willing to invest into the ls vtec thinking that I'll get a 200 whp monster crx but idk anymore.

    Pretty much what I want your opinions and to know if the research I did was just on the lower end $$$ builds and anymore useful information.
    Thanks

    Also my ls vtec build would Consist of mostly everthing from the "ls all motor monster guide"
    B16a head
    crower cams
    Crower valves, springs and retainer caps
    B16 intake manifold until I get money for an aftermarket one
    P30 cams
    Itr water pump
    Itr oil pump
    Itr timing belt
    Arp head studs and rod bolts
    Shot peen ls rods
    I'll probably scavenge for a b16 tranny
    Am I missing anything and I'm open to opinion that may save me money for equal power

    Mild built LS-VTEC motors that are able to support 8000-8500rpm's will be 190-205whp (give or take a few ponies) with a proper tune. The parts you mentioned seem like they'll get you in that area. But you shold get some bearings too. For an OEM build, I think some prefer to go with a P30 piston.

    Numbers/letters combo on crank and rods of the motor to tell you the OEM bearings to buy. OEM is what I'd go with.
