My son has a 91 civic hatch DX with a jdm b16a swap installed. This car has the dx wiring harness which I modified for this conversion. NOW he tells me he is having a b18 block built to replace his perfectly good b16a and will use the head off the b16 on the b18. I'm sure this will work but what else does he need for this swap? going from obdo to obd1, different harness and which one, engine mounts, shiftlinkage, axles, injectors, manifold...... what does he need to do this swap? Of course I searched but it did no good, Please tell me what he needs to have to make this swap work. He doesn't have much time to keep this car off the road, it is his only transportation.

LS/VTECH that isn't a b18 is it?

 

i'm not to sure about this but i'll throw in some info;
just because you are doing an LS/vtec swap doens't mean you NEED to convert to obd1, but you can. to convert to obd1 you'll need an obd0-obd1 conversion harness, new ecu, distributor any obd1 b-series will work some with modification and others without. (i used a obd1 gsr dizzy), and a 4 wire O2 sensor and i believe that is all for converting to obd1
For the block swap you cna get a conversion kit, sold by golden eagle, goes for about 230ish???.... that will let you run your b16 head no problem. other then that you use all of your B16 parts i believe, others can chime in, just gave you a lil info.
But yea, theres tons of info, and it's prolly in the FAQ thread at the top

 

Did he say it was an LS bottom end?

Sean

 

b18 bottom end, b16 head ==LS/VTEC

 

B18 block and a b16 head is commonly termed LS/VTEC
don't ask me why he would buy a gsr bottom to fit a b16 head on

 

is this swap a good idea or not? What is a gsr bottom end? please forgive my stupiditty(SP?) but I've never done this before. am an old time VW restorer that has come to the Honda scene because of 2 teenage sons and I want to make sure that anything we do is right the first time and that I don't have to worry about them breaking down, or if they are losing the race--haha.

its really not a good idea if you're really just worried about it running reliably, especially if he already is running a good b16

 

I'm worried about reliability but being 18 he wants to go fast at the drag strip. The car is on laughing gas and he really is careful on the street, just want to know if the swap is worth the time and money. By the way, he has no money and I wil probably wind up paying for the whole thing, that is why I want to know if it is worth swapping.

 

you'd think that the NAWZZZZ would be enough for him, but if your looking for reliability i would just go with another motor setup. The LS/VTEC if put together correctly would be fine, but since your asking all these questions there is a chance that somethign might be messed up internally. Why not just go for the GSR motor, since u want to convert to obd1 anyway. It'll be way more reliable, and uber fast with NAWZZZ

 

nothing is messed up with the engine he has now, I just think he talks to friends and they say you should have blaablaa blaa and it would be faster. That is why I want to know if the swap is worth the effort. What would be the best way to build horsepower in the JDM b16a swap he has now and still be NA? He does have laughing gas!

 

back to the originalquestion, what is needed for this swap? axles, wiring harness, motor mounts.........---------_________?

 

if he wants to be fast and not worried about breaking anything there always is the good ole b18c5

 

Well to me Nitrous isn't NA..... buttttt, The biggest advantage of staying NA is having less weight, so he could completly strip his car. otherwise, get a better motor for an all motor setup, a b16 is not the best choice, unless you really wanna mess with internals, like stroking it, head work, high compression pistons, etc.. Its more cost effective IMO to slap a turbo setup on it.
Regarding the LS/VTEC setup, its worth it, everyone has different turn outs in power range though

I agree nos isn't NA but he has it and will use it. Back to the original?, Will the components from the b16 work on the b18 or will we have to replace- wiring, axles, injectors (obdo to obd1),dizzy and what else?

 

why do all that work when you already have the best thing in the world, NAWZZZZZZZZZZZZZZZZZZZZ!!!!!!!

 

any other ideas how to search this swap? Itried LS/VTEC and got zero results. Ant ideas are greatly appreciated

 

All you would need is the block, then I suggest you but an lsvtec kit from golden eagle which will include a head gasket, oil line (goes from the back of the block where your oil sensor is) to the head, and a copper tee that plugs into the back of the block. I suggest getting a new water pump unless you want to use the one off the b16 and while you are at it change the timing belt as well. As far as the axles go use the same ones. Most B series parts are interchangeable

 

Where can I order the is/vtec kit and why is an oil line needed going to the head?

Like it was said in the begining tons of info on it out there, and after countless attemps on helping you i decided to do the searching for you

 

Get the proper engine code off the block first if you're not sure what type of B18 he has/wants.

There are a couple of variations on it, that will need different electronics.

The LS engine, the B18A is a non-vtec engine.
Swapping over the head of a B16 will require an oil line kit for the pressure on the vtec solenoid. If he already has a B16 running, you will not need to do any modifications to the wiring. However, you'll want to have the ECU chipped.
1.6l and 1.8l engines obviously have different fuel needs. Several sponsors here provide that service.

I'd keep the B16 intact, and source up a seperate head. That makes the B16 easier to sell.

You can use the same tranny, axles, starter, alternator, injectors etc etc...

An OBD1 upgrade is reccomended.
For this you will need a different ECU, a wiring harness (because the ECU has different plugs) and a new distributor. OBD1 is much much easier to tune after the LS VTEC conversion.

Now if you're getting a different head anyway, it might be worth while to source a B18C1 or a B18C5 head.
The C1 head will need some wiring, because it has an adjustable throttle plenum in the intake manifold. Real nice piece of wizardry gives you some more torque down low. It also has more agressive cam specs than the B16.
The B18C5 head is a type-R head, and has a factory port/polish job, and slightly more agressive cams. Even more so than the C1.
It also uses lighter valves and heavier valve springs.

Just some things to think about.

 

a good how-to here on the lsvtec

Thanks for the info SET120, He is having a block built but I don't have any specs, I didn't even know he was doing this. He says he wants to use the head and trans from the b16 but i"m with you keep the b16 together and source the parts he needs (the b16 would really be nice in his brother's 89 CRX-Si). He has obd0 but said he wants obd1 and I am trying to compile a list of what he will need for the conversion beforehand so his down time is minimal. When I know exactly what block it is , I will post it up.

 

Just talked to my son and he said the block is a GSR block- already vtec.
