Hey dude... I didnt mean anything like what you though. Everytime I come to this forum I see 100 new posts by you about basically the same thing. Confine all your questions into 1 post, then update regularly, as I do. Anyhow, I cna be a big help to your questions i fyou PM me or Post them.
The B20Z swap is a great start, 140HP, 133TQ is a great number to start at. Although, while your at it, you may want to Get a differnet INTAKE MANIFOLD, cuase hte B20's is hella restrictive as is the LS's. A Skunk2 Unit can be bought for about $200 or AN-r, BLOX, etc... just search it out. Check into a header... on G2's you can use hte JDM ITR 4-1 Header from the 98+ Spec ITR, they cost about $300+, bu tyou have to cut a relieve in your front crossmember. Dont get your ecu chipped to rev higher, the B20's have weak Rod Bolts and this will lead to a spun bearing... Anymore questions? Post em.
