What all parts would I need? Just the head or what? I was told to slap on a y8 head, but I dunno if it's a direct bolt-in or if there are other things involved?
Any help would be appreciated for this first-time-honda guy!

in your situation its easier than most, you already have a y8 intake manifold, so just grab the head, slap it on, wire up the knock sensor, and vtec, and plug in the new ecu. bam, you're done.

head gasket, IM gasget, i would recomend using a y8 intake manifold. You can use the stock timing belt. You will need to wire one wire to the vtec solenoid and use a p2p ecu.

85_305

shardbody- How do you know I have a y8 intake manifold? How do I wire the knock sensor and to what? And the same with the vtec... what do I do with that? Is the ecu a direct plug in to the existing harness?
97spooncivic- what is a "p2p" ecu? plug to play or am I off?

85_305

Oh and a quick question.. how will making my 1.6 vtec help with performance?

seabass10369

ok lets start by you telling us what gen and motor you have from the start and we can help you from there. since ur new to honda things might not make sense right a way p2p is the ecu from a 96-98 civic ex with a d16y8 vtec motor

85_305

Oh shoot sorry.. forgot I dont have my new car in the sig. It's a '98 LX 1.6 5spd

seabass10369

ok for starts you'll need a y8 style im( horizontal plenum and normal runners) d16y7 is your motor code the im's are worth much, you'll need y8 injectors, ecu, tb and 2wire iacv, and wire vtech solenoind and pressure switch to ecu. I am SURE you can find a more comprehensive post on this swap, oh and i think pull the oil squirter from block since there is on in the y8 head but like i said dont take this stuff i say as fool proof read up

85_305

Oh boy.. much more than your average SBC swap huh So pretty much I think I'm over my head unless I can get a complete writeup haha

seabass10369

trust me you can find a full write up and its really not that bad you can start off small like swap ims first and then going to full mini-me or do it all at once both have there advantages

schardbody

click on the FAQ sticky at the top of this forum, one of the FIRST writeups is 96-00 mini-me. in all honesty though, you wont be happy with it still, and unless you have all the parts already the couple hundred dollars isnt worth the gain IMO.

and i know you have a y8 intake manifold from the pics you have linked in your other post.

seabass10369

ok so i checked out some pics of the civic in your webshots and i am assuming you bought it modded like it is the manifold you have is edelbrock victor x and you have some headers there which could mean the person who didnt the work might already have head swap but to be sure look for the head number its most likely an ej-somthing ej-6 is y8 or look for a vtec solenoid on the back pass corner of the head just a thought

85_305

seabass10369- well according to schardbody I already have the y8 intake.. and I can find a head for 80$ or so.. how much would everything else I need cost?
schardbody- what kind of gain would I get by upgrading this car to a vtec? I still want to boost it.. but trouble is installing everything then tuning it

edit:
seabass10369- yes I did in fact buy it modded What would the vtec solenoid look like? I will check out the number on the head as soon as I get the car.. I am actually RECIEVING the car wednesday or so But the thing is.. the side of the car says Vtec SOHC.. do you think the sticker is BS, or does that just mean there is a great chance of it being a vtec motor? The guy that's dealing it to me is a dealer in florida whom sells ferraris and porches, and everything else, and even he said that the car is pretty "zingy"..
Doubel EDIT: and even though the car has teh Eddie intake, it will still work with the y8 head the way you are talking I am assuming? How much will the Edelbrock give in hp/tq on average?

schardbody

he is right, it is an eddie manifold (looked again), but definately not a vtec head.

for gains i would say anywhere from 10-15whp max.
AND THAT IS MAX.

85_305

schardbody- deffninently not a vtec head huh? Damn. But 10-15 WHEEL HP?? Just from the intake? I would be satisfied with that.. what will the full vtec upgrade wield me?

97spooncivic

10-15hp is reffering to the vtec head, not the intake. If you can get a head for 80 dollars I think that is cheep. I would do it. Because since you already have an intake manifold, you dont need to buy that or a tb. Pretty much all you need now is a headgasket (or copper spray), P2P ecu, and wire the vtec solenoid and pressure switch. There are great write-ups on here. So you shouldnt be disencouraged from doing it yourself

And you do NOT need to pull out the oil squirter from the block, that is only d15.

seabass10369

yah i wasnt sure on the squirter but would he not still need to change tb if he is using the original tb it has the iacv built onto it and it is a 3wire unit he would need a 2wire manifold mount one and a y8 tb unless you can remove and block off the on on the y7 tb

no need to mess with the oil orfice, its built into the head on Y motors, and no need to worry about the IACV problem cuz its done already.

97spooncivic- 10-15 from the head isn't bad.. how would gas mileage be affected by upgrading to a vtec head? What kind of performance increases will the Eddie intake give on a 1.6 civic? where can I find a p2p, the vtech solenoid and pressure switch (wouldn't those two come w/ teh head??)
And what about wiring harnesses? The p2p is a direct plug in to my current harness or what? Thanks guys, you are amazing so far!

egmatt93

vtec = worse on gas im pretty sure

85_305

oh I thought they were more efficient at a given RPM :D Oh well. I really don't know much when it comes to honda but i'll learn! The performance increase will make up for the gas mileage decrease haha

Vtec should increase gas mileage because the vavles are not fully open and therefore requires less gas. Keep the Eddie intake manifold because its better than a y8, as far as hp goes it depends. maybe like 5hp. You can find a p2p ecu here in the for sale thread or on ebay. I got mine for 40 dollars of ebay which was a really good price. The vtec solenoid and pressure switch come with the head. But i was saying you need to wire them. The p2p is a direct plug and play with your harness.

hey bud i did this swap to my crx wit a jdm SOHC ZC motor... i STRONGLY recommened using the D16Z6 head... its the head from a 92-95 ex vtec, its rated the best head honda ever built, it has the best set-up for valve train and all, trust me buddy... anyway you will need the following parts:

head gasket - 92-95 ex or si (D16Z6)
intake man gasket - 95-95 ex or si (D16Z6) or if your using the Y8 get the D16Y8
exhaust manifold gasket - 92-95 ex or si (D16Z6)
spark plugs - (D16Z6)
spark plug wires - (D16Z6)
timing belt - ((D16Z6)

before you start you are going to have to pull the oil jet plug out of the center back of the block, it looks like a bulb shaped object with a hole in it, that hole can be removed, if you dont remove it you wont tget the oil pressure you need to make your VTEC work. then you'll be in the same position as you are now ... everything you use your going to want to use the parts for THAT SPECIFIC HEAD. like i said i STRONGLY recommend you use the D16Z6 head, so every part you get you need to get for the D16Z6 head!!! its really all self explanitary.. when you get to the timing belt it is going to be a REALLY REALLY tight fit trust me, i have a secret to help you out when you get there. take the bolt out of the timing belt tensioner and remove the tensioner, now you will have the slack that you need to install the new belt, once its on then re-install the tensioner! now the belt is on... you ARE going to need an ADJUSTABLE CAM GEAR, the timing needs to be "ADVANCED 2 DEGREES, this is very very very important. the car will NOT run if you dont advance it, if it does it will have absolutley no power... your done. just hook up your VTEC, and your there.. GOOD LUCK, if you need anything else let me know...

bahahahahaha, who was rating it? It is greatly debated whether the zc is greater than the y8, people are always saying different crap. As far as the best honda head ever built, haha, i would say mayb b16b or itr. How does the zc have the best set-up for valvetrain and all?

What block are you using?

If you have a d16y7 block, YOU DO NOT need to remove any oil jet. that is only for d15 block. If you use a y8 head, you do not need to change the timing belt, spark plug wires, or spark plugs

97spooncivic

and a y8 intake manifold pwns zc's
