Default Crank Pulley or MSD next?

currently- 93 d16z6
dc sports headers
modified stock airbox with K&N filter
gutted cat with 2 1/2 piping into a supertrapp muffler
no power steering
my question, should I underdrive the crank before messing with the ignition?
how about underdriving the alternator?any downside?right now i have the cooling fan hooked up to a toggle switch(so it runs constantly in the summer and spring)

An MSD won't show you any gains over stock unless you're FI or heavily modded NA, and a crank pulley will inevitably lead to a cracked crank... so the pulley will definately cost more in the long run.

Don't underdrive the alt-- an ECU getting less voltage/amperage will make a slower car than one getting plenty of juice. My Sol is noticeably quicker after going from a toasted OEM alt to a 135amp unit...

You have a link for a suggested alternator?

Got mine on eBay for $134 shipped... but that seller doesn't have any items listed right now. Most places go $180-200. Like the header, I got lucky.

how easily is that done on a b series setup? I'd think it'd be the same process. I however, dont have access to things like that.
