DPFI to VTEC conv

[aal]

I just bought a 91rex with a smoky d15b DPI motor

I have ordered a JDM d15b for it but after investigation
I am now considering upgrading that order to a d15b VTEC for $60 more

I would like to know how much trouble this conv would be

this is my first engine swap and I dont want to get stuck with a major project that I cant drive for a while

If it its just swaping a few wires and adding a resistor pak like a DPFI to MPFI I would like to know.

Waddya think?

this project is probably more difficult but better than a zc swap. i've heard a lot of complaints about the zc and i've heard a few good things... but i've heard only good stuff about the d15b vtec. however for the d15b vtec u will need to do wiring for vtec, dpfi to mpfi conversion, and if i'm correct...an si ecu.

So I should stick with the drop-in D15B for my DX

I start a new job 10/25 and wont have time to deal with it then
so I want to get this done in 2or3 days total
am I ?

I hope my motor arrives on time.....

the only real problm is the tranny because d15bvtec is obd1 and is hydro so you gotta swap your old long ass geared dx cable tranny for a si or by the conversion kit!
