Hello everybody. I am your typical early/mid 20's guy, with a Honda looking for help . In the past year I bought a 1994 Honda Civic Ex, with d16z6 with.....automatic transmission . I had plans for swapping this and that and B series and H series and manual swap and, then injured myself in a basketball game and am told to not use my left leg for anything for like a year . So, I started my research for ways to make my automatic civic a little ballsier while staying automatic, for now. I have read of a few people that have successfully swapped a usdm 94/95 integra ls b18b engine and automatic and using the usdm Ls ecu and tcu and being able to chip the ecu. I have also read of a few people who have swapped in jdm integra sir-g (gsr) b18c engine and auto trans using the jdm ecu and tcu, which I've read is not chipable, meaning no cams or pistons, just bolt ons? I've also read of people swapping jdm civic b16 and auto trans using the jdm ecu (no tcu required?) which is not chippable which is not cool to me. So, from what I've read, the jdm gsr auto trans is an mp7a, being better than the usdm ls auto trans which is an sp7a. I've also read that the jdm b16a automatic transmission is an m24a which is also the auto trans mated to the d16 vtec, which is said to be better than the d15 nonvtec s24a found in the us dx and lx. So I am wondering. Could I swap in the jdm b16a and m24a transmission and use a chipped p28? I've read that the integra b18 autos require an external tcu which provides major headaches during the swap, but both the jdm b16a automatic and the usdm d16z6 automatic are m24a which dont require a tcu, and the usdm p28 automatic ecu already controls a d16 vtec and m24a auto trans. So could I use a chipped usdm p28 automatic ecu and control the b16a and jdm b16a-m24a automatic transmission? Sorry for the long post, and thank you to the guys with useful information!
