I am looking to convert to convert to EFI on a 1993 profile with twins. Where would I start and who has had success in this area? Thanks!

What kind of motors? I've got 2 complete MPI's off 1998 502's. Let me know if you're interested.

I've been posting as well to understand what's involved with taking off the carb and intake of my 454 mag and putting on an MPI. I haven't gotten much info as yet, though I believe there is an issue with the head ports shape being correct, adding an electric fuel pump, also with bolt pattern on heads if the engine generation is too old. Again, I'm trying to understand this process and gather details myself. ecu will have to be reprogrammed if it didn't come from the same hp engine... There is one on ebay from a 502 with only 30hrs on it, buy it now price is 600, bids are at 200... Nordicflame here also has one for sale.

I'm interested in putting on two complete mpi's, but want to understand what's involved first before I purchase anything and how much two complete units will cost me.

Fountain38sc, do your units include the ecu? How much are you asking for both sets? Again, I'm not ready to purchase but interested in how to do it and how much this will cost me. And if there are any additional parts I would have to buy.

Thanks!!

suggestion , strip poker has his hp 500 intake set ups and harnesses , give him a hollar . then , call mark at precision
504 469 7463 or www.pmefi.com for any additional info , between the both i'm sure you can get hooked up at a fair price....

I am interested, willing to purchase today, if I know what I will have to do to make them work in a non-MPI boat. THe technical part is where I need to know more before going forward. Thanks.
