    honestly, you didnt search to hard on here... by the sounds of it you want everyone to do the research for you. there are books about building honda engines, have you seen them?

    ur rite i have not yet searched here. and i have also never built anything automotive before in my life. so im sorry if it seems that im not doing anything.
    i have seen the swap books on ebay.
    but i have a question. i found the b16A head but im not sure if i go with all the same year parts to make it easyer or not??
    so i guess thats the biggest thing that i must have over read or sumthin.

    Well search on here.

    If you want to stay OBD0, then get a 88-91 PR3 Head from an SiR Civic. and an OBD0 90-91 PR4 LS Block. You can keep all stock internals, but its going to bite you in the ass.

    Yea, staying obd0, will be easier, cheaper and less of a hassle. But, you will need to tune. LSVTEC's arent going to run off a PR3 or a PW0 ECU as well as it would if you were using maybe a PM6 w/TurboEdit so... oh, the reason it will bite you in the ass... PR4 pistons dont have as good of valve clearance as the PR3 or most aftermarket pistons you can buy (wiseco, etc...) so, if anything get PR3's, they are cheap. You can usually do it for around $85 and they will fit on the LS rods, after either the rod or pistin is shaved for it to fit.

    that transmission wont bolt to the B series. you'll need a cable trans from a 90-93 Integra or 88-91 SiR
