yes, i have searched, and i have not found nearly enough info to begin work. i have a '91 2.0 si b20a that i'll be turboing within the next week or so, and i also have a '91 2.1 si that i'll be dismantling within the next week or so.

question is, what exactly does the conversion consist of? i know the ecu, harness, and distributor are involved... but what goes on?

does anyone at all have a write-up for this? i've searched all over, but ended up with the same useless poo.

i plan on using ghettodyne or uberdata with 440 dsm and 255 lph pump, as opposed to the fmu i have. btw, how will the 12:1 fmu hold up to the 7 psi i'll be pushing (stock pump, injectors)?

thanks for any input.

You shouldnt have to change the dizzy. The ECU conversion should be sufficient.... I dont know... i've never done any B20a swap but have placed a B17 to a civic EF (OBD0). It was a pain in the ass but I remember not tampering with the dizzy.

I dont preach FMU anymore, however I know that 12:1 is more than enough for 7 psi. That is 85 psi plus 40 psi stock fuel under 7 psi boost. That should be enough.

thanks. is there something better then the FMU that you would recommend?

AFC hack...but only if you have an AFC already. I would rather do Uberdata for sure....

FMU = horrible...

AFC hack or Uberdata... Hack is easier but you really dont tune with it. uber gives you much much more flexibility.

sounds like a plan. now i need to find a 88-91 prelude to commence this project. the last car was to much of a "project".
