jsm b20a5

is the wiring different from a b20a5 ro a jsm b20a5?

JSM :confused: :confused:


and are refering to the early prelude B20a5, or a version of the B20a in the US CRV :confused:

and what part of the wiring are you worried about being differt?
what are you doing? swaping motors? :confused:

:cool:

sorry about that thanks i have a honda prelude 88 2.0 si i was going to do a h22 motor swap but then i have heard that is it better do just get a jsm so i was going to do that and i found a jsm b20a5 out of at lude it is getting shipped from japan now but im just wanting to know could there be any difference in the wiring harnce and it the a computer up grade i need to do when i do this swap. thanks

umm.......this may seem a bit straighforward but..

WHAT THE HELL IS JSM?!?!?!?!?!?!?!?!!!!!!! :confused:

I think you mean JDM, as in Japanese Domestic Market.
jsm just sounds like something rude.


Well your basicly swapping the US version of your motor for the Japanese version of your motor. Its exactly the same engine, I dont think there is even a HP differnce.

So there should be no problems with wiring etc, infact you will be able to use your existing inlet and exhasut manifolds, and have things like spare dizy etc from your old engine.


Putting an H22 into your car would be a real mission by the way. :)

look these are the B20's

B20A Gen 2 Prelude Si 160 ps
B20A Gen 3 Accord Si 160 ps
B20A Gen 3 Prelude Si 145 ps
B20A5 Gen 3 USDM Prelude 20.Si 135 hp
B20B CR-V 126 hp
B20Z SM-X 146 ps

these are the DOHC B20's, if any of this seems unbelievable, look at Honda's Japanese site under History. There are numerous B20A's SOHC and DOHC since for the JDM motors they dont use numbers i.e.B20A(5)
all motors regardless of specs are all called B20A.

I have...my number plate got ripped off the back so I have to wait for new ones:(

There is absolutely no difference in the wiring harness from the jdm B20a5 and the usdm B2015. in fact, they match identically to the a20a3 motor to (third Gen accord LXi and SEi). but if you ask me the swap is worthless unless you drive an accord. or a sohc lude. the B20B is hardly even an option for the car and would take way too much money and time and custom shit to worry about. same with the H-22. why don't you just build the motor you have and make it fast, alot easier and less hours
