Hey hows it goin I just bought a y8 head with the intake manifold off ebay. It has 100k miles what kind of maintenence should I do before swapping it on to my y7? I know it needs to be cleaned up but my cousin was saying something about getting it machined? Should I get some new valve stem seals? Y8 timing belt, can I use my y7 distributor and y7 spark plug wires bcuz it didnt come with any. It came with the throttle body and vtec solenoid. Do I need anything else before I perform the swap? I have new y8 headgaskets and Ive been told its a good idea to remove the middle layer for higher compression but would it make it less reliable? Im trying not to spend too much on the mini me but i was also wondering whether I should go with the p28 ecu w/ conversion harness obd2-->obd1 or a p2p ecu and a knock sensor. I know I can only chip with the p28 but I decided after the mini me all I will be doing is I/H/E and maybe an ex tranny. Thank you for your help
So far I spent $127 on head and manifold and $30 for the head gasket ... I need an intake manifold gasket to right?

 

yes, you'll need a gasket. and a timing belt, and a new dizzy. Your dx would not work. Different mountings. And what ever you do, if your not gonng to expect a high hp gain, leave the head gasket alone. Not worth the trouble. And for your ecu, it depends on if you are going to do more upgrade later on down the road. You should get a obd 2 to obd 1 conversion and a p28. don't even chip it if all your doing is a mini me. But you could also get hondata s300 for obd2. They recently came out with it. So its up to you if you want to spend the extra money. You could just find a obd 2 p28, click and play.

 

why shouldnt I change the head gasket I already have one. Is it neccesary to do anything with the head and manifold since they came off a motor with 100k miles?

 

lol no such thing as an obd2 p28

 

yes there is they made them for the del sol's but I dont think I can use one bcuz of fuel maps and fuel regulator

 

I wasz referring to a obd2 to obd 1 harness for my ek which is obd2

No they didnt its called a p2p not p28

 

The Y7 dist WILL work. As will the plug wires. Y7 timing belt = Y8 belt = Z6 belt. They're all the same.

Get a Y8 ECU. Otherwise you will need to buy a P28, a conversion harness, and more than likely a 92-95 harness unless you can find the individual plugs you need from one.

 

why don't you just run a obd1 dizzy with the p28 and a z6 intake mani...granted you won't have that
y8 intake mani but still you should just run the odb1 intake mani and obd1 dizzy should run fine..thats what i'm runnin but then again my **** is a cluster expletive....y8 head d15b7 dizzy and d16a6 block

 

Well I already have the y8 intake manifold and I was thinking about the p28 bcuz I can get vtec to kick in earlier like around 4400 rpm plus I wont need a knock sensor but p28 and conversion harnesses get expensive espicially chipped

 

would you guys advise me to do anything to the y8 head before swapping it on? it has 100k miles on it I dont wanna drop too much money.

 

vtec kicking in at 4400 isnt going to do anything. Honda didnt use any ninja skills to hide power gains by enguageing vtec at a different point if your motor is stock.

The advantage of the p28 is that it can be chipped to change fuel curves and ignition maps. which arent going to help you if your motor is stock compression, stock cam, exc...

vtec xover should only be changed in a sohc when a aftermarket / agressive cam is used. IMO.

 

so im better off goin the p2p and knock sensor route if i only plan on doing i/h/e and trans right?

 

If you're handy enough to add the knock sensor, then yes.

 

honestly im not handy enought to swap in the knock sensor let alone do the entire mini me which is why im having a friend help me out. I have read a post or two about adding the knock sensor and even a post about adding in a type of resistor that can be bought from radio shack so if i can figure that out i can save money on buying and installing the knock sensor.

 

well what i would do to avoid the whole wireharness route just to run obd1 just a a z6 intake manifold and a odb1 dizzy and you should be set i would propley be cheaper then buyin a harness....granted the flow capabilties arn't as good as a y8 intake mani but i'm sure you could make that up in other areas..

 

You don't need a OBD-I dist. Just repin the OBDII. You don't have the run the Z6 IM to have OBDI either. Only thing you need for OBDI is the P28 and a conversion harness. You'll also need OBDII injectors unless you have OBDI injector clips.

That's what i used to think, but actually the z6 is just as good as the y8 IMO.
The designs are similar, the y8 has a bigger plenum and slightly shorter runners. I don't think you will see any better numbers with the y8 over the z6, only powerband changes. But they are both considerably better than the a6 manifold.

 

So I should just get a p2p ecu and knockl sensor and ill be set correct?
