99 si (b16a2) into a 93 del sol si
 

Hey,

Ive gotten some mixed directions on this swap. Ive been emailing Jerome Soh at Sohfast.com and he states that after I get the complete swap kit for the 99 si, I would need to get and intake manifold from a 94-95 del sol for the obd2 to obd1 issue and an ecu from a 94-95 del sol VTEC so the INSIDE harness fits up again for the obd2 to obd1 issue.

Anyone do this swap or something close to it that might point me in some kind of non-confusing direction as to what I might need and not need??!! :)

thanks alot!

well, you pretty much got it :) you will need an obd1 ecu out of a del sol with a b16 or a jdm one so it will plug in to your existing harness, and you can actually more than likely use the obd1 intake manifold, the only sensors on it are the tps, map, and iacv, and the obd1 plugs for those sensors, are the same as the obd2 ones. i've had an obd1 b series and i have a 00 si with an obd2 b16, so i know this. you will need an obd1 b series dizzy (distributor), and injectors, other than that, everything should plug up. you will have to run wires to the ecu for the knock sensor (your stock harness won't have a plug for this) and maybe for vtec also (i'm not too familiar with del sols). good luck.

Re:99 si (b16a2) into a 93 del sol si
 

So this swap isnt as straight forward as everyone says??

So im pretty much getting this info from everone so far:

1. Need a 94-95 del sol VTEC ecu
2. Need to keep the old intake manifold even though the plugs are the same on the obd 2 harness?
3. obd1 b-series inj. and dist!
4. Run some wires from the ECU?

Number 2 sounds a little fuzzy. One reason is cause Ill have to drive to whoever i sold it to on eBay and beat their ass for it! There is no way to use the new int. man.?

Number 4 - b series ecus come with a knock sensor, no? So im good if i get that 94-95 del sol VTEC ecu.

One more thing, am I able to use the new OBD2 harness or should I keep my old harness around just for kicks?

Thanks alot! I shoulda just came here first! :)

Re:99 si (b16a2) into a 93 del sol si
 

this whole post is full of ----.

you have a del sol Si. Use your p28 ECU with the b16a2 intake manifold and injectors and distributor. it will work fine.

the only thing you'll need to do is get the p28 chipped with b16 maps, which cost about $20 for a chip off ebay, or you can have someone make you one.

beats the hell out of paying all kinds of money for ---- you dont need.

Re:99 si (b16a2) into a 93 del sol si
 

Then what would be the difference in chipping my ecu or getting the 94-95 del sol VTEC ecu and not worry about ------- mine up? That ecu already has the b16 maps cause its for a b16a3 which is in that year del sol VTEC.

Re:99 si (b16a2) into a 93 del sol si
 

oh, i didn't see that it he had a del sol si, so yeah, you could just chip your current ecu to run a b16 map, or swap it out for one for a b16 (whichever you feel would be easier), i tell you one thing though, i sure as hell wouldn't buy a chip off of ebay, you may as well bend over, now for your new questions.

1. we just addressed that above
2. no, you don't need you old intake mani, just swap the engine in with the obd2 intake mani on it, the sensors will plug up fine.
3. you can use any obd1 honda injectors (as in the ones out of your current engine will be fine), they are all 240cc.
4. you will have to run wires for your knock sensor (a sensor that is on b series vtec engines), you don't have to use the knock sensor, but you may as well since you have it, and actually, i don't think there is a pin out on the p28 for a knock sensor, so if you do, you will have to get a different ecu.

Re:99 si (b16a2) into a 93 del sol si
 

yeah, if you want to ensure that it runs perfectly the way honda intended it to, then you should just get the ecu (not sure which one it is) from the del sol vtec

Re:99 si (b16a2) into a 93 del sol si
 

Thanks alot for the help!! :) Many MANY questions answered in abuot 1/4 of the time!

one last one though - easy!:

Harness: use the new one (99 si) or the old one (93 delsol si)

Re:99 si (b16a2) into a 93 del sol si
 

when ever doing an engine swap, ALWAYS use the original harness for the car ;)

Re:99 si (b16a2) into a 93 del sol si
 

Oh.. alright then!! Stick that little goodie in my back pocket.

So pretty much the only thing I need is the new ecu and the old injectors?

And the thing about all the obd2 crap on the new engine; they will just be running in an obd1 state?

Re:99 si (b16a2) into a 93 del sol si
 

i bet most of the obd1 sensors are the SAME as the obd2. Just that obd2 has more sensors.

plugs may be different, just re-pin the obd2 plugs on your harness.

sensor voltage ranges are mostly the same.

Re:99 si (b16a2) into a 93 del sol si
 

and don't forget an obd1 distributor for any b series (b18a/b, b16, b17, b18c, b20). as far as running in an obd2 state, there's really no such thing, the only main difference between obd1 and 2 is some of the plugs are a little different, and obd2 ecu's are a little more ---- than obd1 :P

Re:99 si (b16a2) into a 93 del sol si
 

on another note, i swapped an obd2 b18b in to my 93 teg, every thing plugged up exactly the same, except there were like two extra sensors, i just left them hanging, and they were fine ;)

Re:99 si (b16a2) into a 93 del sol si
 

oh ok!! that rounds everything out. Hopefully!! I didnt know about the dist.

my shopping list includes:
93 injectors
obd1 b series dist
94-95 del sol VTEC ecu
keep both harnesses for plugs and such

Am I missing anything?

Re:99 si (b16a2) into a 93 del sol si
 

diapers. for the first time you hit Vtec and rev her to 8grand.

Re:99 si (b16a2) into a 93 del sol si
 

92-95 injectors
yeah, you can keep the extra harness just in case, but like i said, when i swapped an obd2 in to an obd1 car, all the plugs matched up perfect.

as far as diapers for the first time you experience vtec at 8k+ rpms, more like you'll want a turbo, it's not as great as you'll expect it to be, i was in love with my b16 for like a day, now i just think it's pretty :-*

Re:99 si (b16a2) into a 93 del sol si
 

hehe well that all DEPENDS! heh depends.

Alright thanks for the input. Ill post some pics when I get the engine in. Not looking for anything sooner than the end of april. Painting it now! heh

Thanks again!

Re:99 si (b16a2) into a 93 del sol si
 

not in your pig of a 99 coupe!

a crx/del sol would feel way better i bet.

Re:99 si (b16a2) into a 93 del sol si
 

it's a 00 you slut ;)

Re:99 si (b16a2) into a 93 del sol si
 

Welp, the "wife" wont let me get any forced induction. I might have to rethink her!!! hehe. Im going to do the swap this summer and the build the ---- out of it over next winter. i might sneak somethin in later down the road. My boy, specialk, on your boards, just put together a HMT and he is still shitting his pants over it.

thanks again! :)

Re:99 si (b16a2) into a 93 del sol si
 

you would spend less money putting together a turbo kit than if you bought all of the bolt on goodies for your engine, and make tons more power, it's a win win.

Re:99 si (b16a2) into a 93 del sol si
 

just get stiff motor mounts, the wife will enjoy the "race like vibrations" ;D

Re:99 si (b16a2) into a 93 del sol si
 

Yes I would agree about the win win situation, but the problem is that the car cant have FI because of the sick power gain which would also improve my chances of getting to know a guard rail or tele pole on a more intimate level, if you can pick up what im putting down.

The whole reasoning behind it is that im trying to get ridiculous power out of just the engine. Not sure if its going to happen. Id be happy with 200% HP gain off of stock, which would land me in the neighborhood of 270-290 at the wheels.

Re:99 si (b16a2) into a 93 del sol si
 

you're not going to get those kind of numbers with out forced induction, or swapping an f20 (s2k engine) in there :P

Re:99 si (b16a2) into a 93 del sol si
 

ya man, with b16 NA you'd be LUCKY to get 200 w/ EVERY bolt on known to man.

but by that time you would barely be able to drive in on the street.

Re:99 si (b16a2) into a 93 del sol si
 

yeah, not to mention all the damn money it would cost to even get 200 hp out of an na b16, if it's not street driveable by then, at least you can live in it on the street

Re:99 si (b16a2) into a 93 del sol si
 

OBDII injectors are compatible with OBD1 ECU.

The P28 is the most chipped OBD1 ECU and will work perfectly fine chipped with B16 maps, and will cost 1/8 of the price of a P30

OBDII distributor will work fine with an OBD1 ECU.

basically, bolt the engine in, run wires for the knock sensor and go with it.

Re:99 si (b16a2) into a 93 del sol si
 

haha this post is funny lol here is what you need to get the car running. (done swaps liek this more than a few times)---

-you can use the OBD 2 dizzy but you need to cut the connector or make a "conversion harness"
-you can use the OBD 2 intake manifold but you will need the IAT sensor out of the intake tube of the SI.
-the injector clips are diffrent but can be made to work.
-the P28 ECU WILL run a b16a2 engine lean and will need to be chipped or get an OBD1 P30 ECU.
-If you go with the P30 ECU you will need to wire for knock sensor.
-OBD 2 has a sensor mounted on the oil pump for the crank possition sensor, wire it if you use an OBD 2 ECU
-OBD 2 also uses 2 O2 sensors and they needto be wired if you go OBD 2.
- you will need to get a new drivers side mount, the SI's mounts are completely diffrent on that side.
-Use the tranny and rear mount that came with the b16.
-make sure to get the axles as well as the half shaft
-make sure you upgrade your radiator to a del sol VTEC one.
-fuel line is diffrent as well. make sure to get a b16 one.(from the filter to the rail)
-O2 possition will be diffrent, the O2 that you will use if you go OBD 1 is the one before the car and you will have to extend the plug from your current O2 to the rear of the engine just before the cat.
-The plug for the altinator will be diffrent as well. you will need to modify it, i do not belive the D16Z6 alt will work.
-make sure you use the engine harness that CAME with your car!!

That is all i can think of off the top of my head.

Re:99 si (b16a2) into a 93 del sol si
 

ya like that isnt enough already... ;D

Re:99 si (b16a2) into a 93 del sol si
 

Holy christ. Your kickin my ass here!!

-Where can I get that drivers side mount?
-I can use the clips off the new harness and cut them into the old harness?
--Im going to use the p30 ecu
-So i can use the new dist.?
-I can use the new inj. as well as the dist.?

Re:99 si (b16a2) into a 93 del sol si
 

you can modify the injector to fit the housing on the injector clip itsself, but seeing honda used the same injectors in your z6 as they did in the b16, use them and the fuel rail. you can make an OBD 1 to OBD2 dizzy converion harness for the dizzy but its the same internally as the OBD1 dizzy, all the parts are the same. Make sure you get the harness off the old motor so you can use the plugs for it for the knock sensor and the alt. you can use a stock B series (92-97 del Sol VTEC or integra) mount to replace the si mount. i belive the mount that is attached to the block is fine but the mount from the block mount to the engine mount is way diffrent.

Re:99 si (b16a2) into a 93 del sol si
 

i hope this is a manual car...

Re:99 si (b16a2) into a 93 del sol si
 

yes it is a manual!! :) hehe

I dont understand that. Do i need to change the mount that is welded to the car or what? or is that just a bushing?

Re:99 si (b16a2) into a 93 del sol si
 

nono, there is 2 nuts that holds the part of the mount that goes into the motor mount. i dotn know for sure youll have to check on it when you get the motor. here is the SI mount, compair it to your current engine and youll see why you need to change it.

Re:99 si (b16a2) into a 93 del sol si
 

the mount on my si looks nothing like that ???

Re:99 si (b16a2) into a 93 del sol si
 

on every 99-01 civic SI they are

Re:99 si (b16a2) into a 93 del sol si
 

<<--------- 00 ???

Re:99 si (b16a2) into a 93 del sol si
 

So im going to need a mount as well? hmm.... More things to take in consideration. That sucks.

One more thing. I have an MSD SCI Digital+ with a blaster coil and I cant seem to find a modified distributor cap for the 99 si?

Any ideas on where to get a decent engine swap kit at a decent price with a start-up guarantee?

Re:99 si (b16a2) into a 93 del sol si
 

del sol VTEC cap will work, hell and DOHC VTEC cap should work, and teg boy, your weird then lol maby its jsut the 99 si's weird.
