ls vtec questions???

[paliagp]

hey guys,
i have a 90 teg and im doing a standard swap in the very near future.I finally found an ls tranny with all that i need but i figure since the tranny is out, might as well pull the motor out and do some work to it.I plan on getting the block dipped,decked,bored 30 over,etc.....first off, has anyone bored out a b18a before???will it make the walls too thin???now for the pistons, i thought i would save some money and get perforance 30 over rings??has anyone tried these before???remember im on a budget also.for the head, i thought that i would slap a b16 head on it and call it a day but is the b16 head good for my application?my last concern is the ecu.....i figure that my computer will be pretty pissed at me and just wont want to work right so what would i have to do for my computer problem....thanks....
