i am the best...i agree with melt, for awhile I was able to tolerate you, but going around calling everyone noobs when this is probably your first day here and you already have 30+ post, half probably from insulting people and calling people noobs. Look I really don't have a problem with you, but cool it down with your post whoring calling people noobs and being a smart ass.
EDIT: sorry to get O/T, but I really don't know that much about the ZC swap, but im sure you can find plenty of people who do.

ok a zc motorwill bolt up right to your car but it would def. be a good idea to switch over to mpfi. and it would be smart to upgrade to a zc or integra ecu. and thats about it. it will bolt up to your dx tranny but si tranny is the way to go.

OH boy, here we go again.. You better read all this dude!
For starters the diff between 88-89 and 90-91's are plentifull yet few... MPFI is on all the 90-91 (I believe) and DPFI is in the 88-89's... In order to use the ZC with the ZC intake manifold you will have to switch over to MPFI wich in itself is a whole new ball park... (I myself am not sure what all is involved... I just grabed all the stuff off a 90 SI for my D16A6 and moded the harness) The DOHC ZC engine will bold directly into your chassis without using aftermarket mounts, it is however smart to get new stock engine mounts before swaping because the ones in there have been beat on since 1989... The transition will work with a 90-91 SI (D16A6) trany... Use the the SI clutch and flywheel... You will probably want to get a new radiator before swaping the motor but thats just a sugestion and is not neccesary. When you get the engine its always smart to do the internal upgrades while the motor is out. You can get an engine manual for it from haynes its the UK edition in english (Thank me for that later, I looked for days before I found it!) You can use the SI ECU and that will work the best Ive looked at the dyno sheets! People say the ZC ecu is best and the 89 teg (D16A1) is second best because of the fuel maps, the SI ecu runs a little bit leaner and as we all know as far as N/A goes leaner is meaner! I saw 6HP increase when my homie tried the SI ecu instead of the teg one, i dunno about the ZC ones. You will need to modify some headers OR buy the DC top part for the 89 teg D16A1 and the bottom half for the 90-91 SI and you will still need to do some modification to your exaust system.
The best place to but is www.Hmotorsonline.com thats were I got mine. Also I got a few ZC threads started in this forum, there is plenty of information there. your welcome.

thats where I'm geting the motor.
also, why would I need to swap out to MPFI when the engine comes with the intake manifold? would I still need to do the swap? also where do you think I could find a decent Si tranny? I am for sure going to go with the ZC ECU, ive heard really good things about this ecu and wanna give it a try. so here is what is on my list to buy, please tell me if I need anything esle or forgot somthing Si tranny ZC Ecu Inserts exhuast system is that all?
