So first off I would like to say i am new to the hole forum thing so I apologize in advance for any mistakes I make "stupid nubies hu" https://www.nopistons.com/forums/pub...1047683358.gif



That said I have recently bought a 20b engine from a jc Cosmo and am transplanting it into a miata ya that right I said a miata

I've bean told there is something not quite right with me but it's bean done before but I now it will fit I WILL MAKE IT FIT.



I am at the point where I need some Wiring diagrams and pinouts for the 20d ecu i realize they are only in Japanese but I have a friend that can translate for me. if anybody has any or if they can point me in the right direction i would much appreciate it and well you would just rule!! https://www.nopistons.com/forums/pub...#>/bowdown.gif

There are no available engine manuals outside of the Japanese dealer ranks. Plenty of people all over the world have tried to get them to no avail. You're on your own as we pretty much all are with these engines.

Here you go a couple of wiring diagrams for the 20b ecu qualities not the best but should help. If you could get them translated it'd be nice if you could post the translated version for all.

Im not trying to be an ass, but why would you want to know about wiring harness info??

First of all 20b cosmos were automatics?? Unless you want to make your converted Miata to also use auto tranny, I don't see the purpose of getting this info.



Most 20B's on the road today uses aftermarket standalone and that means you need to rewire the set up.. If you are worried about sensors... most of them are similar to FD sensors.. or you could figure them out fairly easily.

whell for now i want to run the car on the stock computer. It is posible to run the automatic computers with a standard transmission because the ecat controler is sepret. I have done this befor I have a 92 mazda b2600 4X4 that I put a 3.0L v6 out of a MPV, the computer was out of an auto van but i am running a standard trans made from half the truck trans and half the van trans so it can be done

cosmo is similar to that. just due to the way the car got wired up, you basically need the dash harness to complete this swap. you also need the coils and ignitors (nothing else in the world works like the cosmo ignition).....

Do you think Cosmo coils and ignitors are better than LS1 or FD??
