Default debating building up a new engine and have a couple question

my local yard has a 3.8 n\a engine setting out in the weeds that i could get for praticly nothing. can i use that block as a starting point? is there an after market blower that makes more boost? since the ecm is already programed to run the engine with positive pressure would it be crazy to build a n\a engine for a twin turbo setup?

I think your biggest concern at this point is money. If you got a good 5k at least, then go for it! PCM and ECM'* are the last of your worrys. What car would it be going into?

93 ssei. right now i'm not too worried about the money but i don't want to dump a whole bunch into it. i am mainly trying to research what method of making boost would be better. twin turbo or super charger. i also am curious if the heads and blower from my car will fit on a 3.8 n\a block

Theres a thread floating around here somewhere about the comparison of heads. I think a twin turbo would be awesome! Definately be unique

Now the question becomes, is it a 3.8 LG3-LG2, or is it a 3800 3.8 LN3, 3800 3.8 L27?
