I just picked up a 93 since it has no maf is it speed density? I know it is OBD1 and has a removable chip in the pcm what else can anybody tell me about it.Is it easier to run a turbo and what other advantages does it have over a mass air car.

Yes, 92(Vette only) and 93 were Speed Density. Welcome to the world of the slightly faster LT1

how is speed density faster?

afaik the 93s were slightly slower (at least for the f-body).

Six one way, half a dozen the other. They're all the same. Just a long standing joke more than anything between the SD and MAF guys.

According to the majority of people on this forum the SD LT1s were just a touch faster, my assumption as to why would be due to their injector firing method which changed in 94. I think SD is called batch, but I'm tired and don't rightly recall. Flipside is probably slightly less fuel economy which is why they changed it in 94.

Pro: (again according to many people on this forum) the SD LT1s take to mods better.

Con? Well we have to still burn our own chips 94+ gets to re-flash their PCM. (Con to that: software is pricey)

Pro: our Automatics aren't computer controlled, so throwing in a TH350, 400, 200R4 wouldn't be so tough

Con, we can't tune in higher line pressure for firmer shifts, but we also don't have to tune the transmission if we upgrade to a bigger throttle body

LT1 is essentially an LT1, and whatever year you get, you'll be happy with it. Unless you're a lucky ****** who snagged an LT4 in 97 via Firehawk or SS or 96 Vettes, then you're really happy

well again, I don't think that's really the case, and I don't think a majority of people think that either but whatever don't really care.
