B20A from gen3 accord. This has been confirmed many times.
B18A/B Requires drilling 2 holes in the manifold flange. I learned of this from bigblockcrx who is no longer on this board and I've verified this one personaly.
B16A/B18C5/ITR/etc other vtec motors that use the same head as the B16A. Justanothermike and I have verified this one. It also requires drilling the flange. 3 or 4 holes I believe, I'm not at home to look at my notes.
Manifolds that don't fit but look close.

The B18C1 manifold is different from the B16A too. I don't know if it fits tough
No good on the B18C1. Its on the C5 that fits. From the 95 integra gsr or whatever.
andy
the c5 is from the integra type r
So I suppose aftermarket (performance) intake manifolds from these engines will also fit. How about the TB?
I would assume that if you can make the manifold fit, you can use whatever throttle bodies normally fit that particular manifold. Anybody know if any of this stuff will also bolt to an Accord B20A with similar modification? Building an engine with that much torque so it could rev to 10k would give me an orgasm...
Exactly ghost!!! Just think once you use another manifold, you'll be able to use any aftermarket part that they may have for that manifold like fuel rails, injectors and tb's....... So with a manifold conversion you have just increased your air and fuel capabilities......:super:
:werd:
Edelbrock ITR manifold has operative range up to 11k I think..
Just image you having a venom manifold, the ones that are built basically for NOS, on a 3rd gen....... Those manifolds are nice as hell!!!:eek:
Yeah, the manifold will fit. Its a b18a btw and starts later then 87 (I think 89). The problem is that the manifold has to tip 15° down to be mounted on an a20a. The b18a sits pretty much strait. I tryed this path already. You can't just bend the manifold, and cutting and rewelding it puts you back at square 1. Only you just paid $500 for a manfiold that you're going to have to cut up. Because the b18a has part of the water jacked in its manifold it pushes the cost up. You don't have to worry about the angle when doing efi, before someone asks.
andy
Also, for anyone who forgot, the B20A is Openloops, 87 LXi hatch is running a B16A manifold; they said it helped the power curve nicely.
My next stop: Skunk 2 B18B manifold. As if I have money, but I can work for it :D
:werd: me and edelbrock are going to do a magic show for yall as soon as i rob a bank or somethin.. :P
http://cgi.ebay.com/ebaymotors/ws/eB...tem=1871743941 If anyone is interesrted I came across this.
andy
I saw on of those on ebay the other day but it was way cheaper than that one...... That would be nice to have......:flash:
So will the B18c manifold fit or not???:confused:
DA FUEL HOLES LINE UP BUT DA OTHAR HOLES DON'T ALL LIEN UP
Say what??? Are you just talking about the B18c??? You know what, I just noticed you're from the burg, I went and played football at Madison........ Small world......:D
so a b16a intake manifold will fit on an A20Ax head right? if you go the fuel injected route, you only need to drill 2-4 more holes in the intake for the bolts to line up, and from then on its a bolt on affiar? you would then need all the sensors, T/b and injectors right? also how would you wire that?
toasty: to rev up to 11k you need more than a solid intake manifold you need a bulletproof valvetrain with better retainers springs etc...
I know that the manifold isn't the only thing that needs heavy upgrading to get that kind of rev range, but I don't want that to be the limiting reagent. AND THIS THREAD IS ABOUT MANFIIOLDS
HARISONBURUG KIKCK ARSE
It's great to finally find someone that knows where the hell this place is...
Which car has the b16a engine in it?
90-93 integra X-Si and R-Si had a b16a in it..Japan only
civics an crx's had b16a's in them also del sol
Individual throttle bodies would be a dream :D

Tell us more!!!:D
so can you make a b18b1 manifold fit on a20 or the head b/c
i have the whole damn motor in my garge
about the motor
Yes. Go get an a20 intake manifold gasket. Tape it on the flange of the b18 manifold. Take a look at which holes don't line up. Then get a drill and make them line up.Quote:

Joker2.
You have a few options for quad throttles. You can pick up a quad tb intake for a b16a and modify it. There are a few companies that make them, twm comes to mind. That'll run you some where around $2400. Or you can make a dcoe style manifold and get some dcoe replacement throttle bodies, again available from twm. The throttle bodies will run you $300 a piece, you need 2, and the manifold can vary but should be between $300-500. With either setup you'll want to talk to our good buddie sean (funstick) about getting a new ecu because the stock one isn't going to beable to handle this.
andy
Well, Phydeaux, I was kinda thinking about the Individual throttle bodies Justanothermike has in his pic, under his name....... Those are nice as hell..... What do you think of those on our cars.....:D
i know the dcoes are a nice power adder so the individual throttle boides should kick ass as well.
Yo Sean, how loud do you think they would be under the hood and should it be like putting a b16 manifold on our cars.......:D
Just wondering if anyone has tried the b16 manifold yet because if not it's going to be nice to be the first.......:flash: :lol :flash:
whats the hp increase for the swapped manifolds ? about, will there even be an increase ?
Anyone found a twin weber manifold supplier?
For fuel injection, cut off the flange from a b20a or a20a intake manifold, get ANY other b series honda manifold (if you get a real new one, look to converting to obd1 for lack of vacuum ports, or just t them off).
Cut the flange off of the b18c manifold (or any other one), you can angle-cut down on the manifold runners if the 15 degree angle difference is going to be a space problem under the hood.
Tig welder - weld the runners back onto the a20a/b20a manifold flange.
Sand and repolish the inside where the flange is welded to the manifolded at the beginning of each runner.
peace
(and good luck finding a tig)
Ok.... I have a twin weber intake from a VW that I can use as a mould....
Is there anything in the 2.0 intake that I should know ? Like does coolant flow through it ? There is a place up here that will cast me a manifold for 70.00 I would have to finish machine the flanges and all the rest...
any insight would be helpfull....
Bob
Cut a flange from an a20a intake manifold (any flange) and get the manifold made, if they'll really cast it for $70... that would be badass.
THe flange is where the runners of the manifold connect to the head, the part that you put the bolts through. No coolant flows through it. Make sure they tap some ports for vacuum to run to your brakes, your PCV valve, and your vacuum advance ignition.
Can they make one to fit a dual 45mm DCOE setup? In other words, twin DCOE carbs (1bbl per cylinder)? The VW manifold probably doesn't have the runners spaced correctly to fit an a20 or b20... but you can probably get them pulled apart or moved or whatever is necessary.
let me know
peace
paul
B carefull not all 'B' runners will be a straight weld to the flanges i.e. B20a4 sohc.
Webers in mind anyone got specs of what angle the b20 sits at? ...it'd maybe help the machiner when making up a mani! Since Webers work best at 5deg. upwards and 7deg. is too much!!!
I read the A20 sits at 15deg? or the mani has to fit at 15?
So the B16 ITB's can be made to fit and guessing angle isn't a concern with F.I.(?) ...anyone used ITB's plus turbo?? the stock tb would make a great mod'd plenum chamber 8-)
The b20a4 sohc is not really a true b-series engine. The purpose of denoting the engine with a b was originally to denote it as a twin-cam engine. Outside that, the b20a4 manifold would not be any improvement over our a20/b20a manifold that we already use.
Regardless, this entire idea begs the conversion to obd1. Obd1 is essential for boosting, using larger injectors (cheap and easy to find DSM ones, for example), more power, and better tuning capability. I think a thread is owed to it.
the b20a4 is sohc.
agreed with the 0bd1.
Just for reference i bought a GSR B18C1 intake gasket and the ports are too high which would leave a gap on top where the injectors go it. So it wont work w/o having some material welded in to cover the gap between the head/manifold. The good news was all the bottom studs lined up exactly. So if your willing to do a little more work it can be bolted up. But im gonna get the B16A i guess since i dont want to hack up a expensive BBK manifold.
ok here is the situation. i have a 88 coupe dx and i want to convert to fuel injected. what all would i need if i want to put a b20a intake into it? (e.i. do i get the ecu off the accord or the crv or get my ecu chipped for the differnt intake?)
uhhh, it'll be easier to just swap over to a fuel injected engine like the a20a3. Swap the engine, ECU, wiring harness, vacuum control box, and you're good to go. You could do it in a weekend.Quote:

yeah, but he's also converting to FI :) Might as well find a whole FI engine, wiring harness, and ECU, imo.Quote:

I heard that the secondary butterflies in the stock A20A3 intake can be blown shut under boost. To fix this, some people have ripped out their butterfly assembly.
Would I be correct in assuming that using a B18/B16 intake would be a better choice?

Well, I don't know if they were actually "blown" shut, or if there was just no vacuum to pull them open while under boost. I will search for the post that talked about it...
I'll spare you the effort. The butterflies close when vacuum is sent to the diaphragm. There is no way they would close under boost. They butterflies will function normally under boost, even if you're seeing positive manifold pressure at a low rpm when they're supposed to be closed. They will stay closed, due to vacuum sealed between the valve and the diaphragm. When the solenoid valve opens and sends manifold pressure to the diaphragm, they will open. I had the 2 stage manifold before I upgraded to the aebs typhoon, controlled by an msd rpm activated switch. The 2 stage is garbage.
I did not find the post I remembered reading, but I did find some interesting stuff along the way:

(Could be useful for the B21A1 head swap where someone said the intake was too tall to close the hood,but it is a less than ideal intake to use)

I just want to point out that the B!8 Intake manifold can'T be used with a DC sports strut bar.... which sucks soooo much.
I don't know about the B18A one. Can anyone confirm if it fits or not? I seriously thing about going back to the stock B20A manifold with all the hassle I've been through.
who can tell me whats the bestest looking but best flowing replacement intake manifold that will bolt on with only drilling/slotting some holes?
i think the b16 one would be the best replacement
a blacktop 20v 4age one :D
