    AEM pulley set:
    http://cgi.ebay.com/ebaymotors/ws/eB...ksid=p3907.m32

    do these do anything on an integra with a b18 or b20?

    i know megan racing is not good for some products, can i trust them for the underdrive pulley?

    would these pulleys well together?

    thx for your input

    They do free a couple of hp from your engine from losing rotating mass.

    my suggestion is, if you are going to do the crank pulley, make sure you do it on a motor build. DOnt just slap it on your factory motor. If you get ur motor rebuilt the crank, pistons, everything will be balanced. Your old motor will prob wear out even faster or do some mighty damage

    does that also apply for a flywheel? i plan on droping either another ls or b20 in my integra because it has so many miles on it and its starting to leak pretty bad. If i get the b20 i need a flywheel for it since it doesnt come with one.

    what are other good bolt ons that i should consider, i already have headers on the way, and have a catback and intake on my car. i was thinking maybe adj cam gears since the engine will need to be tuned with the obd1 conversion.

    bolt-ons: intake manifold, throttle body, header, a turbo BOLTS right on... a nice set of cams would be nice. not too hard to change them out. but...taking off the a/c compressor and powersteering pump ill also help (but i like turning). i've just heard bad things about the crank pulleys UNLESS you get the motor balanced and blueprinted.


    o and a flywheel, i've driven my buddies b18 EK thats boosted with the lightened flywheel and its a REAL paint in the a s s to drive.

    this is only true with engines that use harmonic balancers on the crank pullies... most modern import engines are balanced internally from the factory and decreasing the rotational mass using a lightweight flywheel and/or crankpulley will not throw the engine out of balance, meaning it will not hurt the main bearings or the oil pump rotors...
