hey guys...im new to the rotary engines, ive done many engine swaps in the past (all on hondas) but i found a cosmo 20b with low mileage near me for sale....was wondering if you need a new wiring harness and ecu to go along with it and will the stock tranny bolt up to it? if it doesnt come with the wiring harness (which it doesnt look like from the pic) where to get one? or can i fabricate one from my stock harness...and will the stock ecu work, or should i just upgrage to an aftermarket .... what about intercooler, i imagine i will have to upgrade to a FMIC, and fuel pump upgrade too...

here is the link: http://www.thepartstrader.com/single...0&adnum=194885

most likely i wont do this, but something i would like to know for the future

thanks

 

I'm not an expert on the subject by any means, but from what I've heard, it costs alot of money - 10k to 30k. You have to modify the subframe also. I think the 13b is a great motor, and can be modified to fit most people's hp needs (for alot less then it would cost to fit that 20b in there).

I think that it is a complete waste of money... Unless you need 1000hp and gobs of torque

There was a thread I read a couple of days ago on here with alot of info about the costs of doing this... try doing a search for it.
