b20 exhast manifold

[K-MOD]

Does anyone know if a USDM B16 or B18 header will bolt up to JDM B20? I want to go turbo and if the bolt patterns are the same it wiil be easy to find a turbo manifold. If not who sells a turbo manifold?

I need to know what exhuast manifolds fit the JDM B20a- from JDM 86-89 AccordSI You know the 2.0L DOHC.

If you did a little reading instead of all these posts you would have an answer.

I've been reading I am pretty sure from what I read that the 88-91 Prelude manifolds fit but since I am new to this forum I wanted some help from you guys. I spent about seven hours reading stuff last night. If you dont have an answer please keep the BS to yourself. I am here trying to find out all I can before do my swap withot any problems.

You know Rob is one of the members that has researched the most about the JDM B20a. We will give you help but this topic is almost as common as a CAI thread or a exhaust thread. The search button is one of the finest parts of this stie b/c you can pretty much find everything there.

I dont spread BS and if you read for 7 hours you could have read everything on the B20A multiple times. I have run through all the stuff multiple times myself because there are a lot of parts that work from other engines and i know its here so i dont bother others to re-post stuff that has been talked about several times over. Im not being rude its just every time we have a new person we get the same stuff over and over again which is a waste of the bandwith and makes the "search" portion take longer to go through senseless topics.


If you need help i dont mind helping if you do the little effort on your part and feel free to PM me if you need something clarified. I am in the middle of my buildup and have been finding aftermarket stuff like the recent ARP fasteners that took a bit of time to get the right stuff.

Oh BTW i wont take credit for doing the most research on the B20A because Carotman and Yasu have contributed so much effort into this project. But the 3 of us all put in a lot of time to help others out and take the mystery out of the swap itself. So hopefully the 3 of us will have the swap done in the spring. There are many others involved in this swap as well so hopefully in the end everyone is happy.
