I still need a lot of parts for my B20a. I was just wondering if anyone on here has done the Gold top b20a to the 88-89 lxi swap?? If so please list all of the parts that I will need and any parts that are interchangeable from other cars. This b20a swap is taking wayy longer than I planned
Ok this is what I have so far
1. Pk2 ecu from 88-91 prelude si
2. Distributor from 88-91 prelude si
3. Timing belt from H23 prelude
4. Goldtop B20a block with B20a 5 speed trans. Working on getting power steering pump
5. What intake manifold will work??
6. Will stock injectors work??
7. Will 86-87 a20 throttle body work??
8. What else will I need??

Is the b20 from the 88-91 prelude???
Its the jdm b20a for our accords. Some parts from the U.S. 88-91 preludes will fitOriginally Posted by LiTtLe xOx BitT
Use the intake manifold from your '88 A20A3 with the injectors and throttle body that came with it. You need the igniter from the prelude also. And you'll need to do some wiring. The pk2 ecu also use 2 oxygen sensors, so you'll either need to add an oxygen sensor to your B20A or convert to 1 oxygen sensor.
Did you get the B20A5 water pump and crankshaft timingbelt cam sprocket and B16/B20A5 cam gears to go with the H23 timing belt?
Nope not yet. I'm trying to get a complete list of everything I need. Then I'm going to take the car with all of the parts I need to a performance shop to get it dropped in. Anything else I might need??
You will need a length of shielded wire for the crank sensor.
That's about it. If you reuse your complete old intake maifold like thegreatdane said, you'll be fine.

dam good luck with the swap bro! cant wait to see it done
not to change the subject or anything, but would the wire be able to pick up any interference from the connection between 2 wires?
so let me get this set up straight. is this what i would need?
h23 timing belt
b20a5 water pump
b20a5 crankshaft cam sprocket
b16/b18/b20a5 cam gears
Do you have the gold top or black top??
i'm told it will be a black top.
Then you will have less problems than I will. I have the gold top from 86-87 b20a and my Honda is 88-89. So I will have to switch more things around to get the gold top 2 work. If your b20 is coming with all ot the accesories it will be a easy swap but mine just basically came with the block and nothing else.
yeah, mine is supposed to be basically a front clip without the frame and body panels. but i still need to know what to use when something breaks.
What about the headers Carot?/ Will they fit on the B20a?? And do you still have that mugen valve cover for sale?
an update, i found out it actually is a gold, not black top, b20a.
i would get a 4th gen TB...i heard they are plug and play

The a20a3 exhaust manifold wont fit. just look at the engines or search, completely different exhaust port spacing...
Not that we dont want to help you, we do, but you'd find yourself asking a lot fewer questions if you read through some of the b20a threads sticky and howto/faq. That goes for a couple of other members too.
have one, i just have to put it on. i'm too lazy to go get the necessary gasket. :)
yesterday i went over to picos house and him and his buddy helped me install my CAI....i should of looked at the tb.....snoopy do you knoe the bore on it?

no, not off hand. and i don't think i have a caliper either to measure it. but eyeballing it, it doesn't look that much bigger than stock, maybe 3 mm bigger at the most. maybe you can find out on www.cb7tuner.com
edit: went on cb7tuner and apparently the f22 tb is 57 mm. however, the prelude h22/h23a1 manifold is a bolt-on improvement for them at 60 mm (or 62 mm, that wasn't really clear), so it should also bolt on to us.

Actualy I did search dude. Its bits and pieces of information all over the place. The reason I'm asking so many questions is I just got the B20a block with no accesories. Had I have known that I would have never even bothered to buy it. I just feel we need to get all the info from bare block to finish in one place because I know more members will be doing this swap. For me it has taken me a while because if all the parts I need but I hope it will be worth it in the end. I want to say thanks to you personally cause you have answered a lot of my questions. Now 1 more question what headers willl work??
the A20 hearder will NOT work on the B20.....the only ones are like the b20 lude ones...but even then you will need to figure out something with the downpipe and everthing.

No problem. And I do agree that some of the info might be a bit spread out, so it takes a while to find the answers.
The B20A5 prelude header is the closest fit, almost bolt-on iirc, you should ask twoloudnproud about the excact details since I think he is the latest person to have installed a not already modded B20A5 header.
But I dont think anyone has used a stock B20A5 cast iron exhaust manifold if you were thinking of going cast iron and not a header, but your chances that it fits are good I'd say.
An H22A header can also me modified to fit but involves cutting and welding it and rerouting the downpipe. I'd only recommend for the more experienced people doing that.
