i'm thinking bout getting this engine for my sedan. will i need to do a obd1 conversion to use this engine? i'll probably just get a vtec controller and run the correct ecu. can i use a 88-91 si tranny as welll? any help appreciated

 

might as well do the obd 1 conversion, you will have distributor issues if you don't. if you don't want to do it, you can get a one wire conversion done http://zdyne.com/convhome.html . it ends up being about the same price. no real need for a vtec controller just yet, but fields are basic and go for around $100 used on TR. 89-91 si would be primo for you. the 88 is a little different (spline count? can't remember) you need to change the mount under the timing belt to your old one off your stock 4dr motor. get the flywheel resurfaced and a clutch for a 92-95 si. if you plan on nitrous/turbo/sc anytime soon, you may want to get a good clutch (act, clutchmasters, etc.). don't want to tell you what to do, but general overhaul is easier while the motor is out. it is up to you..

i have a d16y7 with my old obd0 dpfi in it now.

is the installation basically the same as a d16z6?

 

with a y7, i think your dist. bolts right up to that head, no issues. you also don't have to hook up VTEC as there is none. convert to multipoint, KJ does this i believe and he is a reputable person at a decent price, not sure if 60-1EK does it. that would be more like just swapping the same shiet you already have. it's newer and probably has less miles on it. with a shitty transmission, it's not going to accelerate well. get the Si reguardless of the motor (y7,y8,z6,zc,d15b,a6), you'll be happier

 

DOHC16CRX is gonna be doing my MPFI conversion and engine swap.

do you mean get a si wiring harness reguardless what motor i have? i will be getting it from him probably as well.

 

the MPFI swap is going to *usually* add to your existing harness to compensate for the 2 other injectors and shit. the other way to do this swap is to take your harness out, and put in an Si. what i mean is you WILL have an 'Si' harness either way. you need multipoint to take advantage of any swap (d-,b-,or h-series) in your car. what motor is going in, you confused me 2 posts ago...
