ltx12 offers sequential fire (as opposed to the usual wasted spark) and also has 6 spark leads (I *think* the ltx8 only has 4 - paul can confirm this for you)
I'm quite happy with the microtech... I'd recommend it. Paul and I wired it up in a little over a day, with no major issues.
ah, 1jz.
well, I'd go it. that's what I've got running my 1jz.
I cant offer any opinions on the wolf3d from personal experience, but I've heard the microtech is between the wolf and motec. It's designed a little more for track cars than street cars (it's not *quite* as smooth as you'd like up the rev range). but unless you're really picky, you wont notice or mind. I only notice when I go slowly up the revs (which is rare) and am looking for it
