Look man, I think just about everyone here has had enough of your shit, either contribute something constructive (aside from postwhoring) or go somewhere else where your whoring will be better tolerated.

Back to the situation at hand, Info on the ZC Check out this page http://dmoore.com/crx/zc.htm

or just do a search and you will a lot of info.

i have been reading a lot, but I was just notified that the DOHC would need mounts and a b series tranny, is this true?

you newbs dont know what 1/1 means ?

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 fair enough, good attitude theodditie (seriously)

for the record to all the board newbs out there... 1/1 means first view first reply

I just need to find some one that has done a ZC swap on a 88-91 civic dx, than he can answer all my questions.

i have been reading a lot, but I was just notified that the DOHC would need mounts and a b series tranny, is this true?

This to my knowledge is definitly not true. You are able to use your existing motor mounts (I recomend getting new inserts for $20) and for the tranny, you can also use the one you already have. If you have a DX then you should upgrade to an Si tranny. It will also bolt right up. Overall, the ZC swap is very easy. Hope this helps.

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.

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?

ok, so I would need a

Injector Resistor 88-91 si or 88-89 teg

Extra wire or a wiring harness from a si

Injector o-rings and seals

thats is right? do any of these things come witht he engine that I dont have to buy?

All the shits was wired on mine, but then it was whacked off.... I will just send you apic, that sounds about right thoe. Like I said When I got my car it had a D16A6 but the wiring was fucked to all hell... I just went to the pick and pull grabed my the ecu and wiring off a 90 SI... Well anything that looked electical, and stuck it in my car...

ok, Seth, you are dead WRONG!!! sorry, but the MPFI came on 88-91 SI models civic's, crx's and hf crx's and ex sedan's......... only the DX and STD model civic's and DX crx's came with DPFI........

ok, so in reality you dont need the mfpi swap, you just need the wiring harness, it would be pointless to do the mfpi swap becuase the engine alrealy comes with mfpi.........

you will still need stuff like the ECU and injector resistor box and stuff like that, so YES you will need it!

Ok so I was wrong about 1 thing... I didnt see you helping for crap so I posted what I knew... AS I said in my post I wasnt sure about the whole wiring thing... I was just helping him with what I knew like trany ecu and mounts.

ali is correct about the DPFI and MPFI, as for all the wiring, whether or not you have to do the MPFI swap or not, I'm am still a little lost on. tryin to get some help on that on my D16Z6 Swap thread.

Hey man, i wasnt tryin to be mean or anything, i just wanted to get my point accros :D sorry if i came off as a dick! :p
