    i have a quick question... i can get a ls vtec dropout from a local shop who sells em... its a ls bottom end with ls rods, new bearings, p30 pistons, arp head studs, cosmetic head gasket, b16 head, b16 tranny, chipped ecu for $3700... how safe would it be for high revs with the ls rods?

    LS don't have the girdles of the VTEC motors, thus limiting revs, i have seen numerous LSVTEC that has blown when over-revved, NOT TO SAY that the lsvtec motor is bad, it just requires more building. i have seen lsvtec that has been built right that has run really nice, i say spend time on the bottom block, good bluepringting and modifications will be a big insurance policy.

    answer to your question right here


    With a stock b16 head you would stop making power around 8200 anyway. If you want to be a little safer replace the weak LS rod bolts with some ARP's

    you dont need a girdle. and LS rod bolts wont handle 8200 RPMS for too long if at all.

    and if you pay 3700 for that swap you are getting ripped off. for that much they should at least have aftermarket rods and aftermarket pistons. and an upgraded valvetrain w/ cams.

    i dynoed mine a few weeks ago. my ls vec stop making power at 7400ish. stock rods except for the pistons(Pr3). The day after i threw a rod :cry2: . If you have ANY weakness in your motor the dyno will bring it out. I used to rev to 8000 the motor at least 2 a day and no problems. Obvously that stopped when i realized where my power dropped.

    my suggestion is get rid of those rods AT LEAST.

    is a rip off. what ecu is coming with it? a chipped PR4? What clutch, a stock exedy replacement? I think youre gettin ripped off. its cometic, not cosmetic. what lsvtec line kit, GE or some company we havent heard of?

    get more details before you buy at least and yes, replace the stock ls rob BOLTS with ARP's as mentioned above.
