    OK, let me start by saying that you made out like a bandit because it looks to be in very good shape....... Now, I know since you have it now you're eager to put it on and go but I would consider purchasing the performance parts that will fit on that manifold like a overbored TB, fuel rail and performance injectors..... Now I'm not saying that you need them right now but in the end you're going to want them so why not build it right and then put it on...... I think you asked about a P&P job on the head plus port matching, well it won't hurt to do that, it will only improve your performance...... But for right now, you need to pull the head, place the manifold on the head and align the holes and there should be some holes that are left over on the manilfold...... Those will be the holes you will have to drill into the manifold.....

    The only problem I see with this one is that it is OBD-2 or 3 or whatever. we have OBD-0, so some of the sensors will be different and be in different spots. I would definitely contact openloop.

    ok so i will have to drill the HEAD, and not the manifold eh? thats part of the puzzle solved... and since i have never done this before, how big of a project is pulling the heads?

    yeah i cant believe he just gave it to me, its in really great shape, it hasnt been cleaned yet either, so i imagine it will be really spiffy by the time i get around to throwing it on the car.

    and joker youre right about building it up some more, i do PLAN to get fuel rail, injectors, and a bigger TB. those are definetly gonna happen as soon as i can afford them. will my stock TB fit on for now or not? its not permanent, but you know how it goes with the NOW NOW NOW... since i know i cant afford all the other smart supporting mods i figured i would give it a go like this. i figure i will at least P&P the intake manifold, and if i have to have the head of to drill the holes i might as well port match etc... hmm, i cant wait to get this project started.

    as for the hoses and sensors that this uses, i am totally clueless, though ryan, the guy who gave it to me says he will email me a digram of the intake that he got when he bought a gasket.

    Yeah, you'll just be drilling into the head because the manifold already has the holes you need....... I don't believe that your TB will fit on that manifold but you could always give it a try...... But to tell you the truth it wouldn't be worth it anyway because the diameter of the b16 manifold is larger than the A20 so you would be restricting the flow thats coming into the manifold...... You should P&P the head, you can get the manifold polished as well but it's not necessary since Honda already does a decent job of that when they build their performance engines...... Just like if you had a Type-R manifold, you would be a fool to take it to a shop to have work done on it!!!

    ooh no the top of the manifold flange need to be drilled not the head. there no where in the head to drill these hole without hitting water. andy posted a pics a long time ago showing where the b16 intake needed to be modified. and yes the head needs to be portmatched to the b16 intake manifold. please od not drill the head. drill the intake i only need to have 3 holes on the top of the flage. the bottom lins up just fine.

    OK, may bad, I had that backwards!!! "Fun", I mean Sean, HA HA, is right about not drilling the head because I just remembered the studs stick out from the head so just drill the manifold...... That's what happens when you're not paying attention to what your typing.....

    nice... so i think i am understanding how i have to drill.. i will just be drilling holes into the top half of the intake manifold in order to get it properly attached to the head?

    also about the TB, i know i would be restricting a lot of flow, but thats fine as long as i can bolt one on for now. cause i really dont have the $300 to buy an aftermarket b16 TB.. i just want something to get me by...

    and once i get money i will also get the other intellegent supporting mods...

    what i need to know is what is the bare mininum i have to do, to get this going, do i NEED to port match, or is that like a bonus... also, if i were to find a regular civic in the junkyard could i use that TB, or would i need an b16 TB specifically?

    lemme know the cheapest/simplest/fastest way to gain a bit of power, i will eventually do it all right... and if its THAT big of a PITA, i may just keep it all stored away and save for the other mods as well!

    OK, port matching is one of those things that is kinda needed but not necessarly needed for your car to run...... You can get by without it but it'll probably feel like you just have on your old manifold on because of the restriction that's taken place..... As far as the TB, I would check the savage yards first because I really don't believe that the A20 TB will fit but like I said before, try it for yourself and see.......

    hmm, well then SCC has some outrageous prices in their ads... lol... well if they are that cheap i will get one no problem...

    hmm, the fuel rail on our manifold has 4 bolts to hold it on, and the b16 only has 3, do i just use the outer two, or should i get a different fuel rail before i try this? also if i get a different fuel rail which injectors should i get?

    yeah, you should be fine. Its not like the fuel rail is really heavy or puting a lot of torque on anything.

    hmm well lets hope they bolt up...

    i also read on ebay about a TB that fit the b series engine, and the way they described it made most honda TBs seem pretty generic. so i am hoping mine could bolt right on, even though the size would be restrictive!

    I know tons about the B series blocks and what not.. It's what I started on and now I've got another car (89 Accord) that I need to get info on, which is why I'm here. So, let me try to help you out... The B series mani. that you have will use B series tb... I have yet to see an instance where another tb was a direct bolt on affair. I'm interested to learn about this plenum swap... My car is currently carbed, but I would love to go inj... looks like I may take a trip to the jy and see if I can find a head and some hard line.

    lol still nothing yet... actually yesterday i was gonna pick up the gaskets... i have a 80% good gasket for the b16 that i can use for comparioson, and the place that actually had an a20 in stock was gonna be closed by the time i could get there! :P

    anyway, hopefully soon i will get it taken care of. but i am worried about the OBD-I II, all that shit. its totally over my head. but i get the impression from recent reading that i may need a first gen b16 manifold! i sure hope not!!!

    Well, as far as the sensors go, I would just try and get an idea of which sensors are used on that manifold and then compare them to the sensors that you presently have....... I'm sure it can't be that difficult....... And if it gets over your head, contact openloop and I'm sure they can at least point you in the right direction.....

    yeah. but i am so much of a newbie their advice would prolly go right over my head. i cant pretend to know what all that means!

    all i know is, it will be nice to drill the holes, then i want to port and polish the sucker before i throw it on the car. also i am looking into getting some bigger injectors as well.
