Now I am talking about a swap not the stock Si, EX or HF models.

I have a d15b2 that I would like to convert to MPFI but this car is my gas hugger . I dont' want to do the swap and have it eat up my gas. I would be use a pm6 ecu (crx si), 92-95 dx intake manifold with injectors (i'm aware of the obd1 factor), and crx si dizzy (if needed). Sound about right?

I am getting about 35 mpg right now on my STD model but I gun it all around as is. so i am sure it can get slightly better.

I say don't change a good thing. Both my Civic's are DPFI right now, and I'm leaving it that way because my STD gets about 32 mpg and my DX gets about 36 mpg.

If mileage is your #1 factor, the only way I'd go MPFI is if you do the entire HF setup, which wouldn't be worth it IMO.

If you're getting 35 mpg with your setup, no need to change!

 

i was getting 20-21 mpg on dpfi and now i'm getting 38.4 on mpfi

 

35mpg DPFI
32mpg MPFI

Both with the 4 speed manual and an hour of city driving to day to work

 

the BIGGEST change will occur after you convert to MPFI OBD-1 from non-OBD, the four wire O2 and higher resolution maps including injector shut-off when you coast downhill in gear.
